Reduce High Blood Pressure with Mindfulness

 

By John M. de Castro, Ph.D.

 

“meditators showed not only a significant reduction in blood pressure, but they also had nearly 50% lower rates of heart attack, stroke and mortality compared to non-meditating controls.” – Elaine Pomfrey

 

High Blood Pressure (Hypertension) is an insidious disease because there are no overt symptoms. The individual feels fine. But it can be deadly as more than 360,000 American deaths, roughly 1,000 deaths each day, had high blood pressure as a primary or contributing cause. In addition, hypertension markedly increases the risk heart attack, stroke, heart failure, and kidney disease.  Hypertension is present in about 70% of first heart attacks, about 80% of first strokes, and about 70% of chronic heart failures. It is also a very common disorder with about 70 million American adults (29%) having high blood pressure and only about half (52%) of people with high blood pressure have their condition under control. Additionally, nearly a third of American adults have prehypertension, with blood pressure higher than normal, but not yet considered hypertension.

 

High blood pressure, because it doesn’t have any primary symptoms, is usually only diagnosed by direct measurement of blood pressure usually by a health care professional. When hypertension is chronically present over three quarters of patients are treated with antihypertensive drugs. But these medications often have adverse side effects. So, patients feel lousy when taking the drugs, but fine when they’re not. So, compliance is a major issue with many patients not taking the drugs regularly or stopping entirely.

 

Obviously, there is a need for alternative to drug treatments for hypertension. Mindfulness practices have been shown to aid in controlling hypertension. It is not known, however, which practices work best. In today’s Research News article “The Effect of Three Different Meditation Exercises on Hypertension: A Network Meta-Analysis.” See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5424182/, Yang and colleagues compare the effectiveness of three different mindfulness practices, Qigong, Tai Chi, and yoga, in controlling hypertension. They reviewed and summarized 19 research articles from the published literature that measured systolic and diastolic blood pressure before and after training in either Qigong, Tai Chi, or yoga.

 

They report that all three practices helped to relieve hypertension, significantly lowering both systolic and diastolic blood pressure in comparison to control participants. But, they also report that Qigong produced superior results, lowering blood pressure to a greater extent than either Tai Chi, or yoga. It needs to be recognized, however, that the current review did not contain any direct comparisons between the three mindfulness techniques. Rather, different studies employing different techniques were compared statistically. It will be important in the future to explore direct comparisons between techniques within the same study.

 

Regardless, these findings suggest that the amount of exercise is not the important component of the practices for blood pressure reduction. Yoga, arguably, contains the most exercise, Tai Chi next and Qigong last, exactly the opposite ordering to the results. These results are a bit surprising in that Qigong and Tai Chi are very similar, each involving slow mindful movements, breath control, and meditative focus. The difference is that Qigong employs fewer and simpler movements than Tai Chi. It is possible that the simplicity of Qigong is more conducive to clearing the mind and relaxing which in turn reduces blood pressure. It should be emphasized that all were effective in lowering blood pressure. It remains for future research to begin to clarify which of Qigong, Tai Chi, and yoga is best in controlling hypertension.

 

So, reduce high blood pressure with mindfulness.

Abstract

We aimed to use the pairwise and network meta-analysis to estimate the effects of different meditation exercises on the control of systolic blood pressure (SBP) and diastolic blood pressure (DBP). Randomized controlled trials (RCTs) were retrieved from PubMed and Embase up to June 2016, which are published in English and reported on meditation exercise for hypertensive patients. Risks of bias assessment of the included studies were assessed by Cochrane Collaboration Recommendations and network meta-analysis was performed by ADDIS. Mean difference (MD) and its 95% confidence interval (CI) were used as the effect size. A number of 19 RCTs were included in this study. Results of pairwise comparisons indicated that meditation exercise could significantly decrease the SBP and DBP, compared with other interventions (MD = −7.10, 95% CI: −10.82 to −3.39; MD = −4.02, 95% CI: −6.12 to −1.92). With good consistence and convergence, network meta-analysis showed that there were no significant differences between meditation and other interventions on SBP. For DBP, Qigong was significantly lower than “no intervention” (MD = −11.73, 95% CI: −19.85 to −3.69). Qigong may be the optimal exercise way in lowering SBP and DBP of hypertensive patients, but a detailed long-term clinical research should be needed in the future.

Improve Major Depression with Yoga

 

By John M. de Castro, Ph.D.

 

“Yoga gives us an active role in healing. And by slowing down mental chatter through breath work, it helps facilitate self-acceptance. In other words, through practicing yoga, we become quieter and more grounded. Yoga can help perfectionists as well as those who tend to be self-critical or lack self-confidence,” – Janeen Dr. Locker

 

Clinically diagnosed depression is the most common mental illness, affecting over 6% of the population. Major depression can be quite debilitating. It is also generally episodic, coming and going. Some people only have a single episode but most have multiple reoccurrences of depression.  Depression can be difficult to treat. It is usually treated with anti-depressive medication. But, of patients treated initially with drugs only about a third attained remission of the depression. After repeated and varied treatments including drugs, therapy, exercise etc. only about two thirds of patients attained remission. But, drugs often have troubling side effects and can lose effectiveness over time. In addition, many patients who achieve remission have relapses and recurrences of the depression. Even after remission some symptoms of depression may still be present (residual symptoms).

 

Being depressed and not responding to treatment or relapsing is a terribly difficult situation. The patients are suffering and nothing appears to work to relieve their intense depression. Suicide becomes a real possibility. So, it is imperative that other treatments be identified that can relieve the suffering. Mindfulness training is an alternative treatment for depression. It has been shown to be an effective treatment for depression and its recurrence and even in the cases where drugs fail.  Another effective alternative treatment is exercise. But it is difficult to get depressed people, who lack energy, to engage in regular exercise. Yoga is a contemplative practice that is both a mindfulness practice and an exercise. It has been shown to be effective in the treatment of depression and even yogic breathing alone has been found to be effective. So, the combination of yoga practice with breathing exercises should be particularly effective.

 

In today’s Research News article “Treatment of Major Depressive Disorder with Iyengar Yoga and Coherent Breathing: A Randomized Controlled Dosing Study.” See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5359682/, Streeter and colleagues examine the amount of yoga practice needed to treat depression. They recruited adult patients with major depressive disorder and randomly assigned them to receive either a low or a high dose of Iyengar yoga practice combined with a coherent breathing exercise. Treatment occurred over 12 weeks. The 90-minute practice consisted of 60 minutes of yoga, 10 minutes of relaxation and 20 minutes of breathing exercise. In the low dose condition, there were two 90-minute yoga sessions and 3 60-minute home practices per week for a total of 6 hours of practice per week. In the high dose condition, there were three 90-minute yoga sessions and 4 60-minute home practices per week for a total of 8.5 hours of practice per week. The participants were measured before and after training and during training at weeks 4 and 8 for the presence of mental illness and depression.

 

They found that as practice continued over the 12 weeks there were systematic significant decreases in depression. But, there were no significant differences between the low and high dose groups. There were no adverse events other than mild muscle soreness. Hence, they found that yoga practice was safe and effective, producing clinically significant reductions in depression regardless of dose. There wasn’t a control condition, so it might be argued that the results were due to confounding conditions. But, the fact that previous research with appropriate controls demonstrated that yoga practice reduces depression makes it highly likely that the reduced depression in the current study was produced by the yoga practice.

 

It is interesting that there was no difference between the dosing conditions. It might be argued, however, 6 hours of practice per week for 12 weeks is not a low dose. It is possible that this extensive of a practice is all that is necessary to produce maximal effectiveness. It would be useful if future research employed a range of doses including some much smaller than the current low dose. It would also be important to follow-up the results to investigate the long-term effectiveness of the yoga treatment. Regardless, the present study and previous research make it abundantly clear that yoga practice is a safe and effective treatment for major depression.

 

So, improve major depression with yoga.

 

“Some people who haven’t responded to traditional treatments might do well with yoga, because unlike antidepressant drugs, yoga and deep breathing target the autonomic nervous system. If your autonomic nervous system is balanced out, then the rest of the brain works better,” – Chris Streeter

Study Summary

Streeter, C. C., Gerbarg, P. L., Whitfield, T. H., Owen, L., Johnston, J., Silveri, M. M., … Jensen, J. E. (2017). Treatment of Major Depressive Disorder with Iyengar Yoga and Coherent Breathing: A Randomized Controlled Dosing Study. Journal of Alternative and Complementary Medicine, 23(3), 201–207. http://doi.org/10.1089/acm.2016.0140

 

Abstract

Objectives: The aims of this study were to assess the effects of an intervention of Iyengar yoga and coherent breathing at five breaths per minute on depressive symptoms and to determine optimal intervention yoga dosing for future studies in individuals with major depressive disorder (MDD).

Methods: Subjects were randomized to the high-dose group (HDG) or low-dose group (LDG) for a 12-week intervention of three or two intervention classes per week, respectively. Eligible subjects were 18–64 years old with MDD, had baseline Beck Depression Inventory-II (BDI-II) scores ≥14, and were either on no antidepressant medications or on a stable dose of antidepressants for ≥3 months. The intervention included 90-min classes plus homework. Outcome measures were BDI-II scores and intervention compliance.

Results: Fifteen HDG (Mage = 38.4 ± 15.1 years) and 15 LDG (Mage = 34.7 ± 10.4 years) subjects completed the intervention. BDI-II scores at screening and compliance did not differ between groups (p = 0.26). BDI-II scores declined significantly from screening (24.6 ± 1.7) to week 12 (6.0 ± 3.8) for the HDG (–18.6 ± 6.6; p < 0.001), and from screening (27.7 ± 2.1) to week 12 (10.1 ± 7.9) in the LDG (–17.7 ± 9.3; p < 0.001). There were no significant differences between groups, based on response (i.e., >50% decrease in BDI-II scores; p = 0.65) for the HDG (13/15 subjects) and LDG (11/15 subjects) or remission (i.e., number of subjects with BDI-II scores <14; p = 1.00) for the HDG (14/15 subjects) and LDG (13/15 subjects) after the 12-week intervention, although a greater number of subjects in the HDG had 12-week BDI-II scores ≤10 (p = 0.04).

Conclusion: During this 12-week intervention of yoga plus coherent breathing, depressive symptoms declined significantly in patients with MDD in both the HDG and LDG. Both groups showed comparable compliance and clinical improvements, with more subjects in the HDG exhibiting BDI-II scores ≤10 at week 12.

Produce Lasting Improvement in Post-Traumatic Stress Disorder (PTSD) with Yoga

Produce Lasting Improvement in Post-Traumatic Stress Disorder (PTSD) with Yoga

 

By John M. de Castro, Ph.D.

 

“Knowledge of yoga can help relieve us, direct us and give clarity of mind. It is the ultimate self-help. The first step in yoga practice is to link the mind and body through the breath, bringing awareness to what is happening in the moment. Intense feelings and thoughts can be experienced and reduced in intensity as the mind becomes more still and calm and the body allows the sensations to pass. With repeated practice and guidance, a yoga practice can bring long term relief and a fresh perspective on life for PTSD sufferers.” – Art of Living

 

Experiencing trauma is quite common. It has been estimated that 60% of men and 50% of women will experience a significant traumatic event during their lifetime. But, only a fraction will develop Post-Traumatic Stress Disorder (PTSD). But this still results in a frightening number of people with 7%-8% of the population developing PTSD at some point in their life. For military personnel, it’s much more likely for PTSD to develop with about 11%-20% of those who have served in a war zone developing PTSD.

 

PTSD involves a number of troubling symptoms including reliving the event with the same fear and horror in nightmares or with a flashback. PTSD sufferers avoid situations that remind them of the event this may include crowds, driving, movies, etc. and may avoid seeking help because it keeps them from having to think or talk about the event. They often experience negative changes in beliefs and feelings including difficulty experiencing positive or loving feelings toward other people, avoiding relationships, memory difficulties, or see the world as dangerous and no one can be trusted. Sufferers may feel hyperarousal, feeling keyed up and jittery, or always alert and on the lookout for danger. They may experience sudden anger or irritability, may have a hard time sleeping or concentrating, may be startled by a loud noise or surprise.

 

Obviously, these are troubling symptoms that need to be addressed. There are a number of therapies that have been developed to treat PTSD. One of which, mindfulness training has been found to be particularly effective. In today’s Research News article “Yoga for Adult Women with Chronic PTSD: A Long-Term Follow-Up Study.” (See summary below), Rhodes and colleagues examine the ability of yoga practice to treat the symptoms of Post-Traumatic Stress Disorder (PTSD) in women who had persistent symptoms that didn’t respond to treatment. They demonstrated in a prior study that yoga practice produces significant reductions in PTSD symptom severity and PTSD diagnosis and decreases in engagement in negative tension reduction activities (e.g., self-injury), and greater reductions in dissociative and depressive symptoms. In the present study, they performed a long-term follow-up by measuring the participants 1.5 years later for PTSD symptoms, dissociative experiences, depression, engagement in negative tension reduction activities (e.g., self-injury), and stressful life events.

 

They found that 1.5 years after the completion of the study the differences between the yoga and control groups were no longer present. They found that 88% of the women in the yoga practice group continued to practice. After completion of the control condition, the participants were offered training in yoga and 44% chose it. All of these women continued practice later. They found, however, that the higher the frequency of yoga practice at follow-up the lower the levels of depression and PTSD symptom severity and the lower the likelihood of a PTSD diagnosis.

 

These are encouraging results that suggest that yoga practice is an effective treatment for PTSD for women and if the practice continues, the benefits continue for at least a year and a half. But, if the practice is discontinued, the benefits will regress. These results are particularly encouraging as these women were the most difficult and intransigent cases that didn’t respond to other treatments. Yet, they responded to yoga practice. These results suggest that yoga practice should be studied to treat PTSD in men. They further suggest that yoga practice should be incorporated into the treatment package to treat PTSD in women.

 

So, produce lasting improvement in post traumatic stress disorder (PTSD) in women with yoga.

 

“The goal of treatment should be to resolve this disconnect. “If we can help our patients tolerate their own bodily sensations, they’ll be able to process the trauma themselves. . . patients, particularly those suffering from treatment-resistant PTSD, yoga has proved an especially good way to do this.” – Jeneen Interlandi

Abstract:

Introduction: Yoga-the integrative practice of physical postures and movement, breath exercises, and mindfulness-may serve as a useful adjunctive component of trauma-focused treatment to build skills in tolerating and modulating physiologic and affective states that have become dysregulated by trauma exposure. A previous randomized controlled study was carried out among 60 women with chronic, treatment-resistant post-traumatic stress disorder (PTSD) and associated mental health problems stemming from prolonged or multiple trauma exposures. After 10 sessions of yoga, participants exhibited statistically significant decreases in PTSD symptom severity and greater likelihood of loss of PTSD diagnosis, significant decreases in engagement in negative tension reduction activities (e.g., self-injury), and greater reductions in dissociative and depressive symptoms when compared with the control (a seminar in women’s health). The current study is a long-term follow-up assessment of participants who completed this randomized controlled trial. Methods: Participants from the randomized controlled trial were invited to participate in long-term follow-up assessments approximately 1.5 years after study completion to assess whether the initial intervention and/or yoga practice after treatment was associated with additional changes. Forty-nine women completed the long-term follow-up interviews. Hierarchical regression analysis was used to examine whether treatment group status in the original study and frequency of yoga practice after the study predicted greater changes in symptoms and PTSD diagnosis. Results: Group assignment in the original randomized study was not a significant predictor of longer-term outcomes. However, frequency of continuing yoga practice significantly predicted greater decreases in PTSD symptom severity and depression symptom severity, as well as a greater likelihood of a loss of PTSD diagnosis. Conclusions: Yoga appears to be a useful treatment modality; the greatest long-term benefits are derived from more frequent yoga practice.

Improve Attention Deficit Hyperactivity Disorder (ADHD) with Mind-Body Practices

Improve Attention Deficit Hyperactivity Disorder (ADHD) with Mind-Body Practices

 

By John M. de Castro, Ph.D.

 

“mindfulness practice can help us pay attention better, resist distractions, be less impulsive, remember what we are doing in the moment, and regulate our own emotions, it is helpful whether we have ADHD or not. But it holds special interest for those with ADHD.” – Casey Dixon

 

Attention Deficit Hyperactivity Disorder (ADHD) is currently epidemic in the US. Roughly 6.4 million American children have been diagnosed with ADHD and 6.4% of American children are being treated with medication. There has been a 42% increase in the diagnoses of ADHD in the last 8 years. This increase in diagnoses probably represents an increase in awareness and willingness to diagnose ADHD rather than an increase in cases of ADHD. “Many children who like to run and jump may be high-energy. But that doesn’t mean they are hyperactive. To count as ADHD, symptoms have to be on the extreme side and have to cause problems in the child’s life. Also, they have to have been doing this for at least 6 months.” – WebMD

 

What can be done about this huge problem that is affecting such a large proportion of American children and adults? The most common treatment is drugs, like methylphenidate, Ritalin, which helps reduce symptoms in about 30% of the people with ADHD. Unfortunately, the effectiveness of the drugs appears to be markedly reduced after the first year. In addition, the drugs often have troublesome side effects, including nervousness agitation, anxiety, irritability, sleep and appetite problems, head and stomach aches, nausea, dizziness, and heart palpitations. They can also be addictive and can readily be abused. If that’s not enough using drugs that alter the brain in children during the time of brain development is fraught with long-term risks. So, drugs, at present, do not appear to be a good solution, only affecting some, only for a short time, and with unwanted side effects.  Is there a better way?

 

There are indications that mind-body training may be a more effective treatment for ADHD. It makes sense that it should be, as the skills and abilities strengthened by mind-body training are identical to those that are defective in ADHD, attention, impulse control, executive function, emotion control, and mood improvement. Mind-body practices include meditation, tai chi, qigong, yoga , etc. Movement based mind-body practices would appear to be particularly appropriate as they are also exercise and as such an outlet for some of the excess energy.

 

In today’s Research News article “Mind–Body Therapy for Children with Attention-Deficit/Hyperactivity Disorder.” See summary below or view the full text of the study at: http://www.mdpi.com/2227-9067/4/5/31/htm

Herbert and Esparham review and summarize the published research literature on the effectiveness of mind-body practices for the treatment of Attention Deficit Hyperactivity Disorder (ADHD).

 

They report that in general movement based mind-body practices are effective for children with ADHD.  The research suggests that yoga practice improves attention, executive function, sleep patterns, produces less anxiety, more ability to focus at school, and less conflicts in children. The ancient Chinese slow movement practice of Tai Chi also appears to help with ADHD, producing significantly decreased anxiety, daydreaming, inappropriate emotions, and hyperactivity, and improved conduct. Meditation practice also appears to be effective for the symptoms of ADHD. The research indicates that mindfulness meditation practice appears to reduce ADHD symptoms and internalization, and improve attention and thinking. The research suggests that meditation practice acts by producing changes to the brains of children with ADHD.

 

These are exciting findings that suggest that mind-body practices are effective treatments for ADHD in children. This is particularly heartening as these mind-body practices are safe, and unlike drugs, have no significant side effects. They are also inexpensive treatments in comparison to active therapies and drugs. They are also convenient for the children to practice when time is available at home or school. Families and teachers can access online or purchase videos as resources to guide the practices. In addition, there are indications that these practices produce relatively permanent beneficial changes in the children’s brains, suggesting lasting benefits.

 

So, improve attention deficit hyperactivity disorder (ADHD) with mind-body practices.

 

“Mindfulness meditation for people with ADHD? It may seem like a stretch, since difficulty with mindfulness is the very challenge for those with attention deficit hyperactivity disorder. And yet recent research shows that mindfulness training can be adapted for this condition and that it can improve concentration.”  – Lynda McCullough

Abstract

Attention-deficit/hyperactivity disorder (ADHD) is pervasive among the pediatric population and new treatments with minimal adverse effects are necessary to be studied. The purpose of this article is to review current research studying mind-body therapies for treatment of children diagnosed with ADHD. Literature was reviewed pertaining to the effectiveness of movement-based therapies and mindfulness/meditation-based therapies for ADHD. Many positive effects of yoga, Tai Chi, physical activity, and meditation may significantly improve symptoms of ADHD among children.

Improve Veteran Health with In-Person and Telehealth Yoga

Improve Veteran Health with In-Person and Telehealth Yoga

 

By John M. de Castro, Ph.D.

 

“The fact that veterans are embracing yoga and realizing its benefits speaks directly to the stigmas attached to both yoga and PTSD. Veterans practicing yoga illuminate the value of the practice for any person, from any walk of life, not just “new-age hippies.” It also demonstrates that suffering trauma that affects our mental health does not break us or make us any less human.” – Dana Santas

 

Mindfulness training has been shown through extensive research to be effective in improving the physical and psychological condition of otherwise healthy people and also treating the physical and psychological issues of people with illnesses and particularly with the physical and psychological reactions to stress. Techniques such as Mindfulness-Based Stress Reduction (MBSR) and Mindfulness-Based Cognitive Therapy (MBCT) as well as Yoga practice and Tai Chi or Qigong practice have been demonstrated to be particularly effective. This has led to an increasing adoption of these mindfulness techniques for the health and well-being of both healthy and ill individuals.

 

The vast majority of the mindfulness training techniques, adopted so far, however, require a certified trained therapist. This produces costs that many clients can’t afford. In addition, the participants must be available to attend multiple sessions at particular scheduled times that may or may not be compatible with their busy schedules. As a result, there has been attempts to develop alternative distance education approaches such as on-line mindfulness training programs and videoconferencing. These have tremendous advantages in decreasing costs and making training schedules much more flexible. But, the question arises as to whether these programs are as effective as their traditional counterparts. Many believe that the presence of a therapist is a crucial component to the success of the programs and the lack of an active therapist physically present in on-line or videoconferencing programs may greatly reduce their effectiveness. It is not known if yoga practice can be successfully delivered through distance videoconferencing programs.

 

In today’s Research News article “Results from a clinical yoga program for veterans: yoga via telehealth provides comparable satisfaction and health improvements to in-person yoga.” See summary below or view the full text of the study at:

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5381127/

Schulz-Heik and colleagues compared the effectiveness of yoga classes provided to veterans with a wide variety of physical and mental health problems. The classes were either in-person or the same class delivered via videoconferencing to a remote site. The classes were offered 13 times per week. The participants were free to attend whichever classes and how many they wanted on their own schedules. All participants who attended any classes during a two-week period were asked to complete a questionnaire on their satisfaction with the classes, global health, and 16 different health symptoms. Satisfaction with classes was demonstrated as 82% rated them excellent and 98% stated that they enjoyed the classes and 98% would recommend them to a friend.

 

They found that the veterans reported significant improvement in a wide range of physical and mental health symptoms, including overall pain, back pain, headache, upset stomach, sleep problems, energy level, irritability, concentration, anger, depression, anxiety, jumpiness, disturbing memories, and other symptoms. Importantly, the in-person and videoconferencing programs demonstrated equal improvements with no significant differences found between them.

 

These are very interesting results but must be interpreted with caution. There was no active control condition. So, the reported benefits might be due to placebo effects, experimenter bias, demand characteristics, etc. The results though are similar to those reported for yoga practice in randomized controlled trials and it is reasonable to conclude that the current yoga program produced similar benefits. Regardless, it is striking that the videoconferencing program was equally effective as the in-person program. This is important as it suggests that inexpensive mindfulness training can be offered to widespread audiences. In addition, videoconferencing training is convenient for the participants, as they do not have to go to a practitioners site on a particular schedule. This, in turn, allows for the application of yoga training for the prevention and treatment of psychological and physical disorders with busy people, low income people, and even people in remote locations, thus greatly expanding the numbers of people who can benefit.

 

“yoga is being increasingly embraced by Veterans Affairs and the military looking to move veterans off addictive painkillers and offer them alternative treatments for pain.” – Emily Wax-Thibodeaux

Study Summary

Schulz-Heik, R. J., Meyer, H., Mahoney, L., Stanton, M. V., Cho, R. H., Moore-Downing, D. P., … Bayley, P. J. (2017). Results from a clinical yoga program for veterans: yoga via telehealth provides comparable satisfaction and health improvements to in-person yoga. BMC Complementary and Alternative Medicine, 17, 198. http://doi.org/10.1186/s12906-017-1705-4

 

Abstract

Background

Yoga is increasingly popular, though little data regarding its implementation in healthcare settings is available. Similarly, telehealth is being utilized more frequently to increase access to healthcare; however we know of no research on the acceptability or effectiveness of yoga delivered through telehealth. Therefore, we evaluated the feasibility, acceptability, and patient-reported effectiveness of a clinical yoga program at a Veterans Affairs Medical Center and assessed whether these outcomes differed between those participating in-person and those participating via telehealth.

Methods

Veterans who attended a yoga class at the VA Palo Alto Health Care System were invited to complete an anonymous program evaluation survey.

Results

64 Veterans completed the survey. Participants reported high satisfaction with the classes and the instructors. More than 80% of participants who endorsed a problem with pain, energy level, depression, or anxiety reported improvement in these symptoms. Those who participated via telehealth did not differ from those who participated in-person in any measure of satisfaction, overall improvement (p = .40), or improvement in any of 16 specific health problems.

Conclusions

Delivering yoga to a wide range of patients within a healthcare setting appears to be feasible and acceptable, both when delivered in-person and via telehealth. Patients in this clinical yoga program reported high levels of satisfaction and improvement in multiple problem areas. This preliminary evidence for the effectiveness of a clinical yoga program complements prior evidence for the efficacy of yoga and supports the use of yoga in healthcare settings.

Being depressed and not responding to treatment or relapsing is a terribly difficult situation. The patients are suffering and nothing appears to work to relieve their intense depression. Suicide becomes a real possibility. So, it is imperative that other treatments be identified. Mindfulness training is another alternative treatment for depression. It has been shown to be an effective treatment for depression and is also effective for the prevention of its recurrence. Mindfulness Based Cognitive Therapy (MBCT) was specifically developed to treat depression and can be effective even in the cases where drugs fail. Aerobic exercise has also been found to relieve depression. Yoga practice in many ways is ideal as it is both a mindfulness practice and an exercise and it can be practiced in groups or individually at home. It has also been shown to reduce depression.

 

In today’s Research News article “Treating major depression with yoga: A prospective, randomized, controlled pilot trial.” See summary below or view the full text of the study at:

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5354384/

Prathikanti and colleagues recruited patients with mild to moderate major depression who were not currently taking anti-depressive medications and randomly assigned them to receive 8 weeks of either 90 minutes twice weekly of Hatha yoga practice or a wait list control that received 90 minutes twice weekly of education on the history of yoga. The participants were measured before during, and after treatment for depression, cognitive ability, psychiatric symptoms, self-efficacy, and self-esteem. They found that the yoga group had a significantly greater decline in depression and increase in self-esteem than the education control group and 60% of the yoga group, compared to 10% of the education group, achieved clinical remission of depression. No adverse effects were reported.

 

The results of this randomized controlled clinical trial suggest that yoga practice is safe and effective in relieving depression when used as the sole treatment. The fact that 60% of the yoga practice participants achieved clinically significant remission of their depression is particularly heartening. Unfortunately, this was a pilot study and no follow up measurements were taken, so it cannot be determined whether the effects endure. Regardless, it appears that yoga can be successfully applied as a monotherapy for mild to moderate major depression.

 

So, improve major depression with yoga.

 

“Available reviews of a wide range of yoga practices suggest they can reduce the impact of exaggerated stress responses and may be helpful for both anxiety and depression. In this respect, yoga functions like other self-soothing techniques, such as meditation, relaxation, exercise, or even socializing with friends.” – Harvard Mental Health Letter

Abstract

Background

Conventional pharmacotherapies and psychotherapies for major depression are associated with limited adherence to care and relatively low remission rates. Yoga may offer an alternative treatment option, but rigorous studies are few. This randomized controlled trial with blinded outcome assessors examined an 8-week hatha yoga intervention as mono-therapy for mild-to-moderate major depression.

Methods

Investigators recruited 38 adults in San Francisco meeting criteria for major depression of mild-to-moderate severity, per structured psychiatric interview and scores of 14–28 on Beck Depression Inventory-II (BDI). At screening, individuals engaged in psychotherapy, antidepressant pharmacotherapy, herbal or nutraceutical mood therapies, or mind-body practices were excluded. Participants were 68% female, with mean age 43.4 years (SD = 14.8, range = 22–72), and mean BDI score 22.4 (SD = 4.5). Twenty participants were randomized to 90-minute hatha yoga practice groups twice weekly for 8 weeks. Eighteen participants were randomized to 90-minute attention control education groups twice weekly for 8 weeks. Certified yoga instructors delivered both interventions at a university clinic. Primary outcome was depression severity, measured by BDI scores every 2 weeks from baseline to 8 weeks. Secondary outcomes were self-efficacy and self-esteem, measured by scores on the General Self-Efficacy Scale (GSES) and Rosenberg Self-Esteem Scale (RSES) at baseline and at 8 weeks.

Results

In intent-to-treat analysis, yoga participants exhibited significantly greater 8-week decline in BDI scores than controls (p-value = 0.034). In sub-analyses of participants completing final 8-week measures, yoga participants were more likely to achieve remission, defined per final BDI score ≤ 9 (p-value = 0.018). Effect size of yoga in reducing BDI scores was large, per Cohen’s d = -0.96 [95%CI, -1.81 to -0.12]. Intervention groups did not differ significantly in 8-week change scores for either the GSES or RSES.

Conclusion

In adults with mild-to-moderate major depression, an 8-week hatha yoga intervention resulted in statistically and clinically significant reductions in depression severity.

Improve the Psychological Condition of Patients with Spinal Cord Injury with Yoga

Improve the Psychological Condition of Patients with Spinal Cord Injury with Yoga

 

By John M. de Castro, Ph.D.

 

“yoga can be practiced by someone with a spinal cord injury under the supervision of a qualified and experienced yoga therapist. The wide range of practices that range across physical postures, breathing techniques and meditative practices allow for a tailored approach that is within the limitations of the patient/practitioner.” – Narayan Gopalkrishnan ·

 

Spinal cord injury is devastating to the individual. It results in a permanent cutting off the muscles of the body from the central nervous system and as a result paralysis. The severity of the paralysis depends on the location of the injury of the spine with the higher the injury the more widespread the paralysis. In the U.S. there are approximately 17,000 new cases of spinal cord injury each year. The World Health Organization summarizes the problem:

  • “Every year, around the world, between 250 000 and 500 000 people suffer a spinal cord injury (SCI).
  • The majority of spinal cord injuries are due to preventable causes such as road traffic crashes, falls or violence.
  • People with a spinal cord injury are two to five times more likely to die prematurely than people without a spinal cord injury, with worse survival rates in low- and middle-income countries.
  • Spinal cord injury is associated with lower rates of school enrollment and economic participation, and it carries substantial individual and societal costs.”

 

Beyond, the devastating physical consequences of spinal cord injury are difficult psychological, behavioral, emotional, and social issues. The vast majority of patients experience chronic pain and a decreased quality of life. In addition, depression and anxiety disorders are common. Since, spinal cord injury is permanent, it is important to address the pain and psychosocial consequences of the injury that may be present throughout the lifetime. These can be changed and can help the victim engage in a happier and more productive life. Mindfulness training may help. It has shown to be effective in reducing chronic pain, treat depression and anxiety disorders, and improve quality of life following a variety of diseases. Yoga practice includes mindfulness training and also gentle physical exercise which may also be beneficial for patients with limited mobility. Hence, it would seem reasonable to examine the ability of yoga training in treating the psychological consequences of spinal cord injury.

 

In today’s Research News article “Evaluation of a specialized yoga program for persons with a spinal cord injury: a pilot randomized controlled trial.” See summary below or view the full text of the study at:

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5422575/, Curtis and colleagues recruited adults with injuries at a variety of levels of the spinal cord and randomly assigned them to receive either 6 weeks of 50-minute sessions twice a week of seated Iyengar yoga training or a wait-list control. Following the initial 6 weeks the control group also received the yoga training. They were measured before and after training for psychological inflexibility and experiential avoidance, anxiety, depression, self-efficacy, post-traumatic growth, resilience, self-compassion, mindfulness, pain, and pain catastrophizing.

 

They found that the 6-week yoga training produced significant decreases in depression and increases in self-compassion. There were also significant increases in overall mindfulness, in particular observing and non-reactivity. These findings were true regardless of whether the yoga condition was compared to the control condition or whether the scores before treatment were compared to those after treatment. There is a need for a better controlled randomized clinical trial and longer treatment and follow-up periods. But, the present results support the idea that yoga practice is a safe and effective treatment for the psychological consequences of spinal cord injury.

 

These results are suggestive that yoga practice improves the patients’ psychological ability to accept and cope with their situation. The increased self-compassion suggests that the patients become better able to look at their situation with warmth and non-judgement, accepting it and themselves as they are. The decreased depression suggests that the patients become better able to accept their situation and control their emotional reactions. Finally, the increases in mindfulness, suggest that they become better at mindfully observing their immediate situation and not to evaluate it, but accept it as it is. All of these benefits suggest that yoga practice can be successfully implemented with patients with spinal cord injuries, producing improvements in their psychological well-being.

 

So, Improve the Psychological Condition of Patients with Spinal Cord Injury with Mindfulness.

 

“Yoga is ideal for spinal cord injury survivors because the gentle stretching encourages healthy breathing patterns, and can reduce the pain of spending all or most of your day in a wheelchair.” – Zawn Villines

Study Summary

 

Curtis, K., Hitzig, S. L., Bechsgaard, G., Stoliker, C., Alton, C., Saunders, N., … Katz, J. (2017). Evaluation of a specialized yoga program for persons with a spinal cord injury: a pilot randomized controlled trial. Journal of Pain Research, 10, 999–1017. http://doi.org/10.2147/JPR.S130530

 

Abstract

Objectives

The purpose of this randomized controlled trial was to evaluate the effects of a specialized yoga program for individuals with a spinal cord injury (SCI) on pain, psychological, and mindfulness variables.

Materials and methods

Participants with SCI (n=23) were outpatients or community members affiliated with a rehabilitation hospital. Participants were randomized to an Iyengar yoga (IY; n=11) group or to a 6-week wait-list control (WLC; n=12) group. The IY group participated in a twice-weekly 6-week seated IY program; the WLC group participated in the same yoga program, after the IY group’s yoga program had ended. Pain, psychological, and mindfulness measures were collected at two time points for both groups (within 1–2 weeks before and after program 1 and at a third time point for the WLC group (within 1 week after program 2).

Results

Linear mixed-effect growth models were conducted to evaluate the main effects of group at T2 (postintervention), controlling for T1 (preintervention) scores. T2 depression scores were lower (F1,18=6.1, P<0.05) and T2 self-compassion scores higher (F1,18=6.57, P< 0.05) in the IY group compared to the WLC group. To increase sample size and power, the two groups were combined and analyzed across time by comparing pre- and postintervention scores. Main effects of time were found for depression scores, (F1,14.83=6.62, P<0.05), self-compassion, (F1,16.6=4.49, P<0.05), mindfulness (F1,16.79=5.42, P<0.05), mindful observing (F1,19.82=5.06, P<0.05), and mindful nonreactivity, (F1,16.53=4.92, P<0.05), all showing improvement after the intervention.

Discussion

The results indicated that a specialized 6-week yoga intervention reduced depressive symptoms and increased self-compassion in individuals with SCI, and may also have fostered greater mindfulness.

Maintain a Yoga Practice to Improve Absences due to Back Pain

Maintain a Yoga Practice to Improve Absences due to Back Pain

 

By John M. de Castro, Ph.D.

 

“For people with lower back pain, stretching is very important. For example, stretching the hamstring muscles (in the back of the thigh) helps expand the motion in the pelvis, decreasing stress across the lower back. In addition, stretching with yoga increases blood flow, allowing nutrients to flow in, toxins to flow out, and overall nourishment of the muscles and soft tissues in the lower back.” – Fred Busch

 

Low Back Pain is the leading cause of disability worldwide and affects between 6% to 15% of the population. It is estimated, however, that 80% of the population will experience back pain sometime during their lives. The pain interferes with daily living and with work, interfering with productivity and creating absences. There are varied treatments for low back pain including chiropractic care, acupuncture, biofeedback, physical therapy, cognitive behavioral therapy, massage, surgery, opiate pain killing drugs, steroid injections, and muscle relaxant drugs. These therapies are sometimes effective particularly for acute back pain. But, for chronic conditions the treatments are less effective and often require continuing treatment for years and opiate pain killers are dangerous and can lead to abuse, addiction, and fatal overdoses. Obviously, there is a need for safe and effective treatments for low back pain that are low cost and don’t have troublesome side effects.

 

Pain involves both physical and psychological issues. Physically, exercise can be helpful in strengthening the back to prevent or relieve pain. Psychologically, the stress, fear, and anxiety produced by pain tends to elicit responses that actually amplify the pain. So, reducing the emotional reactions to pain may be helpful in pain management. Mindfulness practices have been shown to improve emotion regulation producing more adaptive and less maladaptive responses to emotions. Indeed, mindfulness practices are effective in treating pain and have been shown to be safe and effective in the management of low back pain. Yoga practice is both an exercise and a mindfulness practice which has been shown to have a myriad of health benefits, including relief of chronic pain and relief of chronic low-back pain.  So, it makes sense to further explore the effectiveness of exercise and yoga practice for chronic low back pain.

 

In today’s Research News article “Effects of yoga, strength training and advice on back pain: a randomized controlled trial.” See summary below or view the full text of the study at:

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5372262/

Brämberg and colleagues recruited adult patients with non-disabling low back pain and randomly assigned them to a strength training exercise, kundalini yoga, or evidence-based education group. Strength training consisted of six weeks of 60-minute supervised strength training with encouragement to practice at least twice weekly at home. Kundalini yoga training consisted of six weeks of 60-minute supervised yoga sessions with meditations, breathing, and posture practice, with encouragement to practice at least twice weekly at home.  Evidence-based education consisted of readings that encourage strategies for self-care, information on medication, sick leave and strategies for managing pain. All participants were measured before and after training and 6 and 12 months later for back and neck pain, absences from work, going to work in pain, and adherence to treatment.

 

They found that yoga had a significantly lower drop-out rate suggesting that it was better liked and tolerated than strength training or education. In addition, neck disability was significantly lower in the yoga and strength training groups than the education group, while back pain was significantly improved in the strength training group. Overall there were no significant group differences in absences from work. But, when the groups were separated into participants who adhered to the recommendations and exercised at least twice a week after training and those who practiced less, the adhering groups had significantly fewer absences, greater than 40% fewer, than the education group or the low adherence participants.

 

These are interesting results and suggest that exercise is helpful with low back pain and its consequences for work life. Yoga practice did not appear to produce superior results to strength training for pain or absences. This suggests that the exercise component of yoga practice is what is effective. But, yoga appeared to be preferred and better tolerated as fewer participants dropped out. The results also clearly indicate that continued practice is crucial. No matter what the exercise practice was, it had to be continued after active training in order to continue being effective.

 

So, maintain a yoga practice to improve absences due to back pain.

 

“And in a new, nationally representative survey from the Consumer Reports National Research Center of more than 3,500 adults, yoga (and tai chi, or the like) was helpful to almost 90 percent of the back-pain suffers who tried it. In comparison, 75 percent of people who saw a physical therapist and 64 percent who saw a primary care doctor said the advice or treatment they received gave them relief.” – Consumer Reports

Abstract

Background

Among the working population, non-specific low-back pain and neck pain are one of the most common reasons for sickness absenteeism. The aim was to evaluate the effects of an early intervention of yoga – compared with strength training or evidence-based advice – on sickness absenteeism, sickness presenteeism, back and neck pain and disability among a working population.

Methods

A randomized controlled trial was conducted on 159 participants with predominantly (90%) chronic back and neck pain. After screening, the participants were randomized to kundalini yoga, strength training or evidence-based advice. Primary outcome was sickness absenteeism. Secondary outcomes were sickness presenteeism, back and neck pain and disability. Self-reported questionnaires and SMS text messages were completed at baseline, 6 weeks, 6 and 12 months.

Results

The results did not indicate that kundalini yoga and strength training had any statistically significant effects on the primary outcome compared with evidence-based advice. An interaction effect was found between adherence to recommendations and sickness absenteeism, indicating larger significant effects among the adherers to kundalini yoga versus evidence-based advice: RR = 0.47 (CI 0.30; 0.74, p = 0.001), strength training versus evidence-based advice: RR = 0.60 (CI 0.38; 0.96, p = 0.032). Some significant differences were also found for the secondary outcomes to the advantage of kundalini yoga and strength training.

Conclusions

Guided exercise in the forms of kundalini yoga or strength training does not reduce sickness absenteeism more than evidence-based advice alone. However, secondary analyses reveal that among those who pursue kundalini yoga or strength training at least two times a week, a significantly reduction in sickness absenteeism was found. Methods to increase adherence to treatment recommendations should be further developed and applied in exercise interventions.

Improve Autism with Yoga

Improve Autism with Yoga

 

By John M. de Castro, Ph.D.

 

“Children with autism have very different sensory experiences from other people, and these responses often cause their bodies to get stuck in fight, flight, or freeze modes that divert blood from the digestive organs to the skeletal muscles. This activity results in disrupted digestion, increased heart rate, and shallower breathing—all of which readily provoke anxiety. Yoga helps a student’s body to get out of the ‘fight, flight or freeze’ response, and to feel more relaxed and less anxious. When the body is no longer in the ‘fight, flight or freeze’ response, blood returns to the core and the body can do its work of breathing.” – Louise Goldberg.

 

Autism spectrum disorder (ASD) is a developmental disability that tends to appear during early childhood and affect the individual throughout their lifetime. It affects a person’s ability to communicate, and interact with others, delays learning of language, makes eye contact or holding a conversation difficult, impairs reasoning and planning, narrows and intensifies interests, produces poor motor skills and sensory sensitivities. The diagnosis of autism spectrum disorder (ASD) has been increasing markedly over the last couple of decades. It is currently estimated that over 1% of the world population has autism spectrum disorder (ASD). The Centers for Disease Control estimates that in the U.S. 1 in 68 children (1 in 42 boys and 1 in 189 girls) have autism spectrum disorder (ASD).

 

ASD is a serious disorder that impairs the individual’s ability to lead independent lives including entering relationships or finding and holding employment. Its causes are unknown and there are no known cures. Treatment is generally directed at symptoms and can include behavioral therapies and drug treatments. Clearly, there is a need for effective treatment options. In today’s Research News article “Relaxation Response–Based Yoga Improves Functioning in Young Children with Autism: A Pilot Study.” See summary below or view the full text of the study at:

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3221508/

Rosenblatt and colleagues study the application of yoga practice for autism spectrum disorder (ASD) in a pilot investigation.

 

They recruited children between the ages of 3 to 16 who were diagnosed with ASD and divided them into preschool (ages3-4), latency (ages 5-12), and adolescence (ages 13-16) groups. The children continued their usual treatments plus practiced yoga for 45 minutes once a week for eight weeks. Parents were instructed to encourage yoga practice at home guided with a CD. The program included breathing techniques, postures, music and dance, and relaxation. The participants were measured before and after the 8-week treatment period for behavioral symptoms, atypicality, depression, externalizing, internalizing, aberrant behaviors, and irritability.

 

They found that the latency group (ages 5-12) after the 8 weeks of yoga practice showed significant improvements in behavioral symptoms, atypicality, depression, externalization, internalization, and irritability. These are interesting results, but it was a pilot study, lacking a control condition. So, conclusions must be highly tempered. Nevertheless, over the course of the study the 5 to 12-year-old children had significant improvements in ASD symptoms.

 

It is particularly interesting that atypicality was improved. Atypicality involves the core characteristics of autism, including all of their atypical behaviors, behaviors well outside the norms. Interestingly, it also involves extremes in intelligence, from genius to retardation. So, yoga practice appears to go right to the core of autism and improve the unusual behavior that are typical of ASD. This is particularly significant and provides impetus to performing a large randomized clinical trial of yoga practice as a treatment for autism spectrum disorder.

 

So, improve autism with yoga.

 

”But seeing the kids—many of whom were extremely anxious, withdrawn, or angry—let go, for even a moment, was a revelation. We were amazed at how effective yoga was with these children and how much they enjoyed it.” – Louise Goldberg.

Abstract

Objectives

The study objectives were to develop and objectively assess the therapeutic effect of a novel movement-based complementary and alternative medicine approach for children with an autism-spectrum disorder (ASD).

Design

A within-subject analysis comparing pre- to post-treatment scores on two standard measures of childhood behavioral problems was used.

Settings and location

The intervention and data analysis occurred at a tertiary care, medical school teaching hospital.

Subjects

Twenty-four (24) children aged 3–16 years with a diagnosis of an ASD comprised the study group.

Intervention

The efficacy of an 8-week multimodal yoga, dance, and music therapy program based on the relaxation response (RR) was developed and examined.

Outcome measures

The study outcome was measured using The Behavioral Assessment System for Children, Second Edition (BASC-2) and the Aberrant Behavioral Checklist (ABC).

Results

Robust changes were found on the BASC-2, primarily for 5–12-year-old children. Unexpectedly, the post-treatment scores on the Atypicality scale of the BASC-2, which measures some of the core features of autism, changed significantly (p=0.003).

Conclusions

A movement-based, modified RR program, involving yoga and dance, showed efficacy in treating behavioral and some core features of autism, particularly for latency-age children.

Bikram Yoga Does Not Affect Cardiovascular Risk Factors with Healthy Participants

Bikram Yoga Does Not Affect Cardiovascular Risk Factors with Healthy Participants

 

By John M. de Castro, Ph.D.

 

“those with a regular yoga practice are likely to adopt a healthy lifestyle, and to experience lower levels of perceived stress and depression than runners or inactive adults.” – B. Grace Bullock

 

Cardiovascular disease is the number one killer, claiming more lives than all forms of cancer combined. “Heart disease is the leading cause of death for both men and women. About 610,000 people die of heart disease in the United States every year–that’s 1 in every 4 deaths. Every year about 735,000 Americans have a heart attack.” (Centers for Disease Control). A myriad of treatments has been developed for heart disease including a variety of surgical procedures and medications. But the safest effective treatments are lifestyle changes. These include quitting smoking, weight reduction, improved diet, physical activity, and reducing stresses. Other safe and effective treatments are contemplative practices, such as meditation, tai chi, and yoga, have also been shown to be helpful for heart health. These practices have also been shown to be helpful for producing the kinds of lifestyle changes needed such as smoking cessation, weight reduction, and stress reduction.

 

Yoga is a mindfulness practice that has been shown to improve physical well-being and cardiovascular health. Bikram Yoga is somewhat unique yoga practice as it employs a set sequence of 26 poses (asanas) and two breathing exercises. It is practiced in a heated environment (105°F, 40.6°C, 40% humidity) and there is a unique programmed instructional dialogue. The hot environment is thought to soften the muscles making them more pliable and loosen the joints making them more flexible allowing the practitioner to go deeper into poses. The sweating that occurs is thought to help remove toxins and impurities.

 

In today’s Research News article “Effect of a 16-week Bikram yoga program on heart rate variability and associated cardiovascular disease risk factors in stressed and sedentary adults: A randomized controlled trial.” See summary below or view the full text of the study at:

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5399826/

Hewett and colleagues examined the effectiveness of Bikram yoga to alter cardiovascular risk factors. They recruited sedentary, stressed, adults and randomly assigned them to receive either a 16-week, 90 minute, 3 times per week, Bikram Yoga program or a no-treatment control condition. They were measured before and after training for heart rate variability, resting systolic and diastolic blood pressure, and heart rate, c-reactive protein, triglycerides, total cholesterol, low-density- and high-density lipoprotein cholesterol, total cholesterol to HDL ratio, and fasting blood glucose, height, weight, waist circumference, body composition, health status, and attendance at yoga sessions.

 

Surprisingly, they did not find any significant group differences in any of the measures before or after training. But, when they looked at attendance ay the Bikram Yoga sessions they found that the more sessions attended the greater the decrease in diastolic blood pressure, body fat percentage, fat mass, and body mass index. So, there appeared to be some modest benefits of high levels of attendance to Bikram Yoga sessions.

 

These are disappointing results. But, the lack of change produced in cardiovascular risk factors by participation in a Bikram Yoga program may have resulted from the fact that the participants were healthy, although sedentary, to begin with. It is possible that significant effects would have been evident if unhealthy participants were examined. On the other hand, it is possible that this form of yoga is simply not an effective means of reducing cardiovascular disease risk in healthy, sedentary individuals.

 

“Yoga has a powerful effect on stress and hypertension and can help people reduce the amount of medication they need. . . researchers reported significant reductions in blood pressure for interventions incorporating three basic elements of yoga practice: postures, meditation, and breathing. “ – Amy Wheeler

Effect of a 16-week Bikram yoga program on heart rate variability and associated cardiovascular disease risk factors in stressed and sedentary adults: A randomized controlled trial. BMC Complementary and Alternative Medicine, 17, 226. http://doi.org/10.1186/s12906-017-1740-1

 

Abstract

Background

Chronic activation of the stress-response can contribute to cardiovascular disease risk, particularly in sedentary individuals. This study investigated the effect of a Bikram yoga intervention on the high frequency power component of heart rate variability (HRV) and associated cardiovascular disease (CVD) risk factors (i.e. additional domains of HRV, hemodynamic, hematologic, anthropometric and body composition outcome measures) in stressed and sedentary adults.

Methods

Eligible adults were randomized to an experimental group (n = 29) or a no treatment control group (n = 34). Experimental group participants were instructed to attend three to five supervised Bikram yoga classes per week for 16 weeks at local studios. Outcome measures were assessed at baseline (week 0) and completion (week 17).

Results

Sixty-three adults (37.2 ± 10.8 years, 79% women) were included in the intention-to-treat analysis. The experimental group attended 27 ± 18 classes. Analyses of covariance revealed no significant change in the high-frequency component of HRV (p = 0.912, partial η 2 = 0.000) or in any secondary outcome measure between groups over time. However, regression analyses revealed that higher attendance in the experimental group was associated with significant reductions in diastolic blood pressure (p = 0.039; partial η 2 = 0.154), body fat percentage (p = 0.001, partial η 2 = 0.379), fat mass (p = 0.003, partial η 2 = 0.294) and body mass index (p = 0.05, partial η 2 = 0.139).

Conclusions

A 16-week Bikram yoga program did not increase the high frequency power component of HRV or any other CVD risk factors investigated. As revealed by post hoc analyses, low adherence likely contributed to the null effects. Future studies are required to address barriers to adherence to better elucidate the dose-response effects of Bikram yoga practice as a medium to lower stress-related CVD risk.
