Improve Low Back Pain with Walking and Mind-Body Practices

 

By John M. de Castro, Ph.D.

 

“Mindfulness training teaches us to be aware of, and accept, moment-to-moment physical sensations of discomfort, while letting go of our usual negative reactions. So instead of spending hours each day thinking about how much we hate our back pain, worrying about our prognosis, and seeking relief, we learn how to be with the pain — paying attention to how it actually feels at each moment and relaxing our tendency to tense up against it, while observing our worried or distressed thoughts and feelings coming and going.” – Ronald Siegel

 

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. 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. 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 has been shown to have a myriad of health benefits. These include relief of chronic pain. Yoga practice has also been shown to be effective for the relief of chronic low-back pain.  Other mind-body  practices such as Tai Chi  improves spinal health and reduces pain. The evidence is accumulating, so, it would seem reasonable to summarize what has been learned regarding the ability of mind-body practices to treat chronic low back pain.

 

In today’s Research News article “Effectiveness of walking versus mind-body therapies in chronic low back pain: A systematic review and meta-analysis of recent randomized controlled trials.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7458239/ ) Nduwimana and colleagues reviewed, summarized, and performed a meta-analysis of the published randomized controlled trials comparing the effectiveness of m1nd-body practices and walking for the relief of chronic low back pain. They identified 31 published trials containing a total of 3193 participants.

 

They report that the published research found that both walking and m1nd-body practices were effective in significantly reducing low back pain. Of the m1nd-body practices, yoga was particularly effective not only reducing pain but also producing significant reductions in activity limitations resulting from low back pain. On the short-term (up to 3 months) yoga produced significant pain reductions while on the intermediate-term (3 to 6 months), walking produced significant pain reductions.

 

These results are important as low back pain is ubiquitous and produces not only discomfort but also limitations on the ability of patients to conduct their lives. So, its relief greatly reduces the suffering and improves the quality of life. The comparison of mind-body practices to walking is important as both are exercises and their relative effectiveness assessed. The results suggest that yoga practice has better short-term effectiveness while walking appears to be better for the intermediate term. This further suggests that future research should explore the effectiveness of the combination of mind-body practices and walking in the treatment of low back pain.

 

So, improve low back pain with walking and mind-body practices.

Study Summary

 

Nduwimana, I., Nindorera, F., Thonnard, J. L., & Kossi, O. (2020). Effectiveness of walking versus mind-body therapies in chronic low back pain: A systematic review and meta-analysis of recent randomized controlled trials. Medicine, 99(35), e21969. https://doi.org/10.1097/MD.0000000000021969

 

Abstract

Purpose:

Walking and mind-body therapies (MBTs) are commonly recommended to relieve pain and improve function in patients with chronic low back pain (CLBP). The purpose of this study was to compare the effectiveness of walking and MBTs in CLBP.

Methods:

We included randomized controlled trials (RCTs) comparing walking or MBTs to any other intervention or control in adults with CLBP. Studies were identified through PubMed, Cochrane Library, PsycINFO, Scopus, and ScienceDirect databases. The research was limited to studies published in English and French between January 2008 and December 2018. Two reviewers independently selected the studies, extracted data, and assessed studies quality using the Physiotherapy Evidence Database (PEDro) scale. Statistical analyses were performed under a random-effects model. We analyzed pain and activity limitation, with the calculation of standardized mean differences and 95% confidence intervals for the different treatment effects.

Results:

Thirty one randomized controlled trials involving 3193 participants were analyzed. Walking was as effective as control interventions in the short-term and slightly superior in the intermediate term with respect to pain (Standardized mean differences (SMD)  = –0.34; 95% CI, –0.65 to –0.03; P = .03) and activity limitation (SMD = –0.30; 95% CI, –0.50 to –0.10; P = .003). In contrast, yoga was more effective than control interventions in the short term in terms of pain (SMD = –1.47; 95% CI, –2.26 to –0.68; P = .0003) and activity limitation (SMD = –1.17; 95% CI, –1.80 to –0.55; P = .0002). Yoga was no longer superior to the control interventions for pain at the 6-month follow-up.

Conclusion:

MBTs, especially yoga, seem to be more effective in the short term, and walking seems to be more effective in the intermediate term, for the relief of pain and activity limitation in patients with CLBP. A combination of walking and MBTs fits the biopsychosocial model and might be valuable therapy for CLBP throughout follow-up due to combined effects.

Reduce the Symptoms of Schizophrenia with Mind-Body Practices

 

By John M. de Castro, Ph.D.

 

“Research shows that some mindfulness-based interventions for psychotic symptoms can afford people a greater acceptance and insight into their experiences. They can also reduce the symptoms of anxiety and depression which often accompany, and may exacerbate, psychotic disorders.” – Adrianna Mendrek

 

Schizophrenia is the most common form of psychosis. Its effects about 1% of the population worldwide. It appears to be highly heritable and involves changes in the brain. It is characterized by both positive and negative symptoms. Positive symptoms include hallucinations; seeing and, in some cases, feeling, smelling or tasting things that aren’t there, or delusions; unshakable beliefs that, when examined rationally, are obviously untrue. Negative symptoms include a reduced ability to function normally, neglect of personal hygiene, lack of emotion, blank facial expressions, speaking in a monotone, loss of interest in everyday activities, social withdrawal, an inability to experience pleasure, and a lack of insight into their symptoms. The symptoms of schizophrenia usually do not appear until late adolescence or early adulthood.

 

Schizophrenia is very difficult to treat with psychotherapy and is usually treated with antipsychotic drugs. These drugs, however, are not always effective, sometimes lose effectiveness, and can have some difficult side effects. Mindfulness training has been shown to be beneficial for a variety of mental health problems, including psychosis. Mindfulness has also been shown to associated with lower symptom severity of schizophrenia. Also, there is accumulating research that mindfulness and yoga practices may be beneficial for patients with major mental illnesses. Tai Chi and Qigong  practices have also been shown to improve the symptoms of schizophrenia. The evidence is accumulating. So, it makes sense to step back and summarize what has been learned about mind-body practices as treatments for schizophrenia.

 

In today’s Research News article “Effects of Mind-Body Exercises on Schizophrenia: A Systematic Review With Meta-Analysis.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7457019/ ) Wei and colleagues review, summarize and perform a meta-analysis of the published controlled research studies of the effectiveness of mind-body practices to improve the symptoms of schizophrenia. They included Tai Chi, Qigong, yoga, and other mindful movement practices. They identified 13 studies (11 randomized controlled trials) employing a total of 1159 patients with schizophrenia.

 

They report that the published studies found that mind-body practices produced significant improvements of both the positive and negative symptoms of schizophrenia and also depression. In addition, the greater the number of weekly mind-body sessions the greater the improvement in the positive symptoms and the greater the duration of the mind-body sessions the greater the improvements in the negative symptoms.

 

These results are impressive as schizophrenia is difficult to treat. But the results show that mind-body practices are safe and effective treatments that improve not only the positive and negative symptoms of schizophrenia but also the frequently co-occurring depression. There also appears to be a dose response effect such that the greater the frequency and duration of mind-body practices the greater the benefits. This suggests that mind-body practices should be recommended as a part of the treatment for schizophrenia.

 

So, reduce the symptoms of schizophrenia with mind-body practices.

Abstract

Background

Mind–body exercises (MBEs) have been widely accepted as a complementary therapy for the patients with low exercise tolerance. Currently, the number of experimental studies investigating the effect of MBEs for improving symptoms in people with schizophrenia is increasing. However, results are inconsistent.

Methods

We systematically reviewed and meta-analyzed the effects of mind–body exercises on schizophrenia. Seven electronic databases (Pubmed, Web of Science, PsycINFO, Embase, Cochrane Central Register of Controlled Trials [CENTRAL], CNKI and Wangfang) were screened through October 2019 and risks of bias of included studies were assessed in Review Manager 5.3.

Results

Meta-analysis on 13 studies with 1,159 patients showed moderately significant effects in favor of mind–body exercise intervention to improve positive symptoms (SMD = 0.31; 95% CI 0.01 to 0.60; p = 0.04), negative symptoms (SMD = 0.37; 95% CI 0.14 to 0.60; p = 0.002), and depression (SMD = 0.88; 95% CI 0.63 to 1.13; p<0.00001). Meta-regression analysis revealed that the improvement in positive symptoms was positively associated with the frequency of intervention (p = 0.04), while a marginally significant correlation was observed between the improved negative symptoms and duration of each session (p = 0.06).

Conclusions

This meta-analysis supports the therapeutic effects of MBEs to aid in the treatment of schizophrenia. Further studies need to incorporate rigorous design and large sample size to identify the optimal type and dose of mind–body exercise to inform clinical practices on MBEs’ recommendations for the management of schizophrenia symptoms.

Reduce Inflammatory Responses and Reduce Rheumatoid Arthritis Symptoms with Yoga

Reduce Inflammatory Responses and Reduce Rheumatoid Arthritis Symptoms with Yoga

 

By John M. de Castro, Ph.D.

 

“yoga practice significantly decreases the severity of physical and psychological symptoms in patients with active rheumatoid arthritis.” – Science Daily

 

Arthritis is a chronic disease that most commonly affects the joints. Depending on the type of arthritis, symptoms may include pain, stiffness, swelling, redness, and decreased range of motion. It affects an estimated 52.5 million adults in the United States. It is associated with aging as arthritis occurs in only 7% of adults ages 18–44, while 30% adults ages 45–64 are affected, and 50% of adults ages 65 or older. Due to complications associated with rheumatoid arthritis (RA), the lifespan for people with RA may be shortened by 10 years. This is due to a higher incidence of cardiovascular disease in rheumatoid arthritis (RA) patients, with the risk more than double that of non-RA individuals.

 

Obviously, there is a need to explore alternative treatments for rheumatoid arthritis. One possibility is contemplative practice. A variety of which have been shown to have major mental and physical benefits including a reduction in the inflammatory response and have been shown to improve arthritis. Indeed, yoga practice has been shown to be effective in treating arthritis. So, it makes sense to investigate the effects of yoga practice on the inflammatory response in patients with rheumatoid arthritis.

 

In today’s Research News article “Effect of an 8-Week Yoga-Based Lifestyle Intervention on Psycho-Neuro-Immune Axis, Disease Activity, and Perceived Quality of Life in Rheumatoid Arthritis Patients: A Randomized Controlled Trial.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7492675/ ) Gautam and colleagues recruited adult patients with rheumatoid arthritis and continued with their usual care. They were randomly assigned to either no-treatment or ashtanga yoga practice modified for patients with rheumatoid arthritis. They practiced 5 times per week for 2 hours for 8 weeks. The practice included postures, breathing exercises, meditation, relaxation, and personal lifestyle management. They were measured before and after training for disease activity and quality of life. They also had blood drawn and assayed for biochemical markers of inflammation.

 

They found that in comparison to baseline and the no-treatment group, the yoga group had a significant decrease in rheumatoid arthritis disease activity and a significant increase in their psychological and social quality of life, with greater effects occurring in women than in men. In addition, they found that yoga practice decreased the gene expressions of and levels of pro-inflammatory biochemical markers IL-6, TNF-α, and CTLA4, and a significant increase in TGF-β, an anti-inflammatory marker, suggesting reduced inflammation in the yoga group.

 

This study did not have an active control condition or a long-term follow-up and as such the results must be interpreted with caution. Future studies should include long-term follow-up and an active control condition such as aerobic exercise to determine if the results were due to exercise in general or specifically to yoga practice and whether the benefits were lasting. Nevertheless, the results replicate the findings of other research that yoga practice improves arthritis symptoms and reduces inflammatory responses. The results suggest that yoga practice reduces the inflammatory responses that promote the disease and thereby reduce the disease symptoms which in turn improves the patient’s quality of life. This is good news for these patients signaling that practicing yoga may help relieve their suffering and retard disease progression.

 

So, reduce inflammatory responses and reduce rheumatoid arthritis symptoms with yoga.

Study Summary

 

Gautam, S., Kumar, M., Kumar, U., & Dada, R. (2020). Effect of an 8-Week Yoga-Based Lifestyle Intervention on Psycho-Neuro-Immune Axis, Disease Activity, and Perceived Quality of Life in Rheumatoid Arthritis Patients: A Randomized Controlled Trial. Frontiers in Psychology, 11, 2259. https://doi.org/10.3389/fpsyg.2020.02259

 

Abstract

Various external stressors and environmental challenges lead to the provocation of the immune system in autoimmune diseases like Rheumatoid arthritis (RA). The inappropriate immune response further triggers the cascade of inflammatory changes resulting in precipitation of symptoms and hampers quality of life (QOL). The underlying psycho-somatic component of the disease requires a holistic approach to its treatment dimension rather than the use of pharmacotherapy. The applicability of mind-body interventions has become essential in today’s fast-paced life. Yoga, a mind-body technique, alters the mind’s capacity to facilitate systemic functioning at multiple organ system levels. Hence, we conducted this study to evaluate the impact of 8 weeks of a yoga-based lifestyle intervention (YBLI) on psycho-neuro-immune markers, gene expression patterns, and QOL in RA patients on routine medical therapy. A total of 66 patients were randomized into two groups: yoga group or non-yoga group and were assessed for a panel of inflammatory cytokines (IL-6, IL-17A, TNF-α, and TGF-β), mind-body communicative markers (BDNF, DHEAS, β-endorphin, and sirtuin) and transcript levels of various genes (IL-6, TNF-α, NFKB1, TGF-β, and CTLA4). We assessed disease activity and QOL using the DAS28-ESR and WHOQOL-BREF questionnaire, respectively. Yoga group observed significant improvements in the levels of markers, which influenced the psycho-neuro-immune axis (p < 0.001) with an estimated effect size from small to medium range. In the yoga group, there was a significant reduction in DAS28-ESR (p < 0.001) and improvement seen in the physical health, psychological, social relationships domains (p < 0.001) of QOL, except environmental (p > 0.05). The yoga group showed downregulation of IL-6, TNF-α, and CTLA4 and upregulation of TGF-β. These results suggest that a decrease in disease activity after yoga practice is associated with a significant reduction in inflammatory cytokines, the elevation of mind-body communicative markers, and normalization of various transcript levels, which improved QOL. Thus the adoption of YBLI improves clinical outcome in RA, and decreases systemic inflammation by its beneficial effects on psycho-neuro-immune axis and normalization of dysregulated transcripts. Thus YBLI may be used for RA patients as an adjunctive therapy.

Meditative Yoga is Superior to Power Yoga in Reducing Stress and Anxiety

Meditative Yoga is Superior to Power Yoga in Reducing Stress and Anxiety

 

By John M. de Castro, Ph.D.

 

“It may seem like yoga styles are all basically the same, but in reality more than a hundred different schools of yoga exist.” – Justin Young

 

Stress is an integral part of life. But if stress, is high or is prolonged it can be problematic. It can damage our physical and mental health and even reduce our longevity, leading to premature deaths. So, it is important that we develop methods to either reduce or control high or prolonged stress or reduce our responses to it. Mindfulness practices have been found routinely to reduce the psychological and physiological responses to stress.

 

Yoga practice has been shown to have a myriad of benefits for psychological and physical health, social, and spiritual well-being. It is both an exercise and a meditative practice that stresses both mental attention to present moment, movements, breath control, and relaxation. There has, however, not been much attention paid to which components of yoga practice that are important for reducing anxiety and the physiological responses to stress.

 

In today’s Research News article “A Comparison of the Acute Effects of Different Forms of Yoga on Physiological and Psychological Stress: A Pilot Study.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7503485/ ) Marshall and colleagues recruited physically inactive healthy adult women. They were provided with 2 30-minute yoga sessions separated by 48 hours of power yoga and meditative yoga in counterbalanced order. Power yoga emphasized physical postures while meditative yoga focused on mental focus, breathing, and relaxation. Before and after each yoga session the participants were measured for state anxiety and salivary cortisol levels.

 

They found that compared to baseline after meditative yoga there was a significant reduction in anxiety and salivary cortisol while after power yoga there were no significant changes in either measure. This suggests that meditative yoga improves mood and reduces stress while power yoga does not.

 

This study replicates prior research studies that have demonstrated that yoga practice reduces anxiety and stress levels as indicated by salivary cortisol levels. Yoga practice, however, contains a number of different components. The present study separates the exercise component, postures, from the meditative components, mental focus, breathing, and relaxation. The findings suggest that it is these meditative components and not the exercise components that are responsible for yoga’s ability to improve mood and reduce stress.

 

This study should be seen as a pilot study. It was small and of short duration. Yoga practice is not usually confined to only a single brief session but usually occurs as a number of sessions over a sustained period of time. It is possible that different results might occur after several sessions. It remains for future research to examine this.

 

So, meditative yoga is superior to power yoga in reducing stress and anxiety.

 

“Power yoga is a general term used to describe a vigorous, fitness-based approach to vinyasa-style yoga. Though many consider power yoga to be superficial “gym yoga,” this style of yoga practice was originally closely modeled on the Ashtanga method.” – Ann Pizer

Abstract

Yoga is a frequently recommended stress management strategy; however, the acute stress response to varying types of yoga are not fully clear. Thus, the purpose of this study was to compare the acute effects of meditative and power yoga on indices of physiological and psychological stress. In a crossover counterbalanced design, physically active females (n = 13; age = 20.8 yrs ± 0.8, height = 164.5 cm ± 6.1, body mass = 65.0 kg ± 13.8) who did not regularly participate in yoga or mindful training enrolled in this study. Participants completed two visits each, with a standardized instructional-video 30-min yoga session with either A) meditative (Hatha style) yoga or B) power (Vinyasa style) yoga. Prior to and immediately after each yoga bout, psychological stress was assessed using the State–Trait Anxiety Inventory (STAI) questionnaire, and salivary cortisol samples were obtained to measure indices of physiological stress. State anxiety scores were significantly lower following meditative yoga (p = 0.047) but were not different following power yoga (p = 0.625). Salivary cortisol levels were significantly lower following meditative yoga (p = 0.020) but not following power yoga (p = 0.242). Results indicate that acute engagement in meditative yoga decreases markers of psychological and physiological stress, while power yoga does not impart a significant stress-relieving benefit. Findings indicate that differing types of yoga may have various stress-relieving capabilities and should be considered by individuals seeking anxiolytic benefits.

Increase Brain-Derived Neurotrophic Factor (BDNF) with Mindfulness

Increase Brain-Derived Neurotrophic Factor (BDNF) with Mindfulness

 

By John M. de Castro, Ph.D.

 

“BDNF is a key neurotrophin that promotes development, survival and plasticity of neurons in the central and peripheral nervous systems.” – B. Rael Cahn

 

The nervous system is a dynamic entity, constantly changing and adapting to the environment. It will change size, activity, and connectivity in response to experience. These changes in the brain are called neuroplasticity.  Over the last decade neuroscience has been studying the effects of contemplative practices on the brain and has identified neuroplastic changes in widespread area. and have found that meditation practice appears to mold and change the brain, producing psychological, physical, and spiritual benefits. These brain changes with mindfulness practice are important and need to be further investigates.

 

Brain-Derived Neurotrophic Factor (BDNF) is a key molecule circulating in the blood that promotes neural, neuronal survival and regeneration which produces neuroplasticity. There have been a number of studies performed on the ability of Mindfulness practices to affect the levels of BDNF found in the blood. It makes sense, then to review what has been learned.

 

In today’s Research News article “The Effect of Mindfulness-Based Intervention on Brain-Derived Neurotrophic Factor (BDNF): A Systematic Review and Meta-Analysis of Controlled Trials.” (See summary below or view the full text of the study at: https://www.frontiersin.org/articles/10.3389/fpsyg.2020.02209/full?utm_source=F-AAE&utm_medium=EMLF&utm_campaign=MRK_1437459_69_Psycho_20200922_arts_A ) Gomutbutra and colleagues review, summarize, and perform a meta-analysis of the effects of mindfulness practices on the circulating levels of Brain-Derived Neurotrophic Factor (BDNF). They identified 11 published randomized controlled trials.

 

They report that the published research studies found that mindfulness training either by meditation or yoga practice produced a significant increase in circulating levels of Brain-Derived Neurotrophic Factor (BDNF). Hence the published research suggests that meditation and yoga practice produce increased levels of BDNF in the blood. Since BDNF promotes neuroplasticity, this may be the mechanism by which mindfulness practices change the brain and thereby improve health and well-being. Of course, much more research is needed but this is a promising potential mechanism whereby mindfulness produces its benefits.

 

So, Increase Brain-Derived Neurotrophic Factor (BDNF) with Mindfulness.

 

“mindfulness meditation and mind-body exercise (e.g. yoga and tai chi) increase circulating BDNF concentrations in healthy and diseased individuals.” – Tongjian You

Study Summary

 

Gomutbutra P, Yingchankul N, Chattipakorn N, Chattipakorn S and Srisurapanont M (2020) The Effect of Mindfulness-Based Intervention on Brain-Derived Neurotrophic Factor (BDNF): A Systematic Review and Meta-Analysis of Controlled Trials. Front. Psychol. 11:2209. doi: 10.3389/fpsyg.2020.02209

 

Background: This systematic review aims to answer three questions. First, how much do mindfulness-based interventions (MBIs) affect peripheral brain-derived neurotrophic factor (BDNF)? Second, do mindfulness exercise–based interventions (exercise-MBIs) and mindfulness meditation–based interventions (meditation-MBIs) affect peripheral BDNF differently? Third, does the age of participants and the accumulative hours of MBI practice affect peripheral BDNF?

Methods: We included randomized controlled trials comparing MBI and no intervention in adults (age >18 years) who reported peripheral BDNF. Database searches included PubMed, CINAHL, CENTRAL, PsyInfo, and Scopus. Two reviewers independently selected the studies and assessed the trial quality. We used the standardized mean difference (SMD) as the effect size index and conducted moderator analyses.

Results: Eleven studies are included in this systematic review. Five studies applying exercise-MBI and three studies applying meditation-MBI are included in the meta-analysis (N = 479). The pooled effect size shows a significantly greater increase of peripheral BDNF in MBI groups compared to the control groups (k = 8, N = 479, SMD = 0.72, 95% CI 0.31–1.14, I2= 78%). Significantly more increases of BDNF in the MBI groups are found in both subgroups of exercise-MBI and meditation-MBI. The effect sizes of both subgroups are not significantly different between subgroups (χ2 = 0.02, p = 0.88). We find no significant correlation between the effect sizes and the age of participants (r = −0.0095, p = 0.45) or accumulative hours of MBI practice (r = 0.0021, p = 0.57).

Conclusion: The heterogeneous data of this small sample-size meta-analysis suggests that MBI can increase peripheral BDNF. Either exercise-MBI or meditation-MBI can increase peripheral BDNF.

Improve Executive Control in Thinking with Yoga

Improve Executive Control in Thinking with Yoga

 

By John M. de Castro, Ph.D.

 

“yoga can be a cognitive enhancement or brain fitness exercise that can confer similar or even more extensive cognitive resilience than memory training-the gold standard-in older adults.” – Helen Lavretsky

 

Mindfulness training has been shown to be effective in improving physical and psychological health and also decreases the individual’s tendency to use tried and true solutions to problems and thereby improves cognitive flexibility. Yoga practice has been shown to have a large number of beneficial effects on the psychological, emotional, and physical health of the individual and is helpful in the treatment of mental and physical illness. Yoga practice has been shown to improve both social–emotional and cognitive skills.

 

To better understand the effects of yoga practice on young adults it is important to take into consideration that yoga is a not only a mindfulness practice, but it is also a physical exercise. It is also a complex practice that can include a number of practices including postures, meditation, breathing exercises, chanting, mantras, and relaxation. It is difficult to understand which components or combination of components are necessary and sufficient to produce improvements in cognition in young adults. Hence, it is important to investigate the differential effectiveness of different components of yoga practice.

 

In today’s Research News article “Enhancing Executive Control: Attention to Balance, Breath, and the Speed Versus Accuracy Tradeoff.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7069337/ ) Singh and Mutreja performed 2 studies to examine the postural control and breath control aspects of yoga training and their differential effects on the cognitive abilities of young adults.

 

In study 1 they recruited yoga naïve university students and had them complete measures of cognitive ability. They then were trained in yoga postures and breathing for 70 minutes twice a week for 8 weeks. 5 days after the last session they were measured again with the same measures and a new set of measures of cognitive ability. During every yoga session instructors rated the participants for postural and breath control and after the session they completed measures of positive and negative emotions.

 

They found that errors in breathing exercises were related to better short-term memory. Additionally, breath control was related to slower responding on cognitive planning tasks and faster responding on cognitive flexibility tasks. On the other hand, postural control was related to slower responding with fewer errors of perseveration.

 

In study 2 they recruited similar participants and had them complete the same measures over the same time periods as study 1 but no yoga training was conducted. The cognitive performances of these control participants were compared to the yoga trained group from study 1. They found that in comparison to baseline and the control group, after yoga training there was a significant increase in the accuracy but not the response speed on the various cognitive tasks.

 

These studies and results are interesting and suggest first that training in yoga improves cognitive performance in young healthy adults. Yoga’s ability to enhance cognition has been previously reported. Importantly, these studies also suggest that different components of yoga training, breath control and postural control are related to different speed and accuracy components of cognitive performance. This suggests that different components of yoga practice and training may have different influences on changes in cognitive abilities produced by the training.

 

These studies are important in that they begin the process of dismantling the complexities of yoga training and their relationships to the effects of yoga training. This can lead to a better understanding of how yoga practice effects cognition and to an optimization of yoga practice to improve cognitive performance. This can lead to better academic and work performance in young adults and potentially to reduced cognitive decline with aging.

 

So, improve executive control in thinking with yoga.

 

” Yoga practice may result in improved cognitive performance, among other potential benefits in healthy adults.” – Devon Brunner

Abstract

Malleability of executive control and its enhancement through yoga training is unclear. In Study 1, participants (yoga group; n = 27, mean = 23.27 years) were tested on executive control tasks pre- and post-8 weeks of yoga training. The training focused on attention to postural control during yoga asanas and respiratory control during pranayama-breathing (30 min each of postural and breath control training, biweekly). Yoga training was assessed via performance ratings as to how well a posture was executed and by examining errors that reflected inattention/failures in postural and breath control. We also explored whether attentional demands on motor and respiratory control were associated with three components of executive control (working memory, cognitive flexibility, and inhibition) during nine executive control tasks. Partial correlation results revealed that the three components of executive control might be differentially impacted by postural and breath control and selectively associated with either speed or accuracy (except for cognitive flexibility). Attentional demands influenced the link between postural, breath, and cognitive control. In Study 2, comparisons between a yoga group and a gender-matched control group (control group; n = 27, mean = 23.33 years) pointed toward higher working memory accuracy and a better speed–accuracy tradeoff in inhibitory control in the yoga group. A ceiling-practice effect was addressed by examining yoga practice learning (i.e., practice-induced change in postural and breath control reflected in ratings and errors) on executive control performance across two sets of tasks: repeatedly tested (pre- and post-8 weeks) and non-repeatedly tested (post-8 weeks). Attention to motor and respiratory control during yoga might be considered as a potential mechanism through which specific components of executive control in young adults might be enhanced potentially via altering of speed–accuracy tradeoff.

Yoga is the Preferred Exercise for the Treatment of Type 2 Diabetes

 

By John M. de Castro, Ph.D.

 

“By increasing muscle mass through strengthening poses, yoga can improve your metabolism, helping you maintain a healthy body weight. Studies suggest that regular practice helps normalize blood pressure and cholesterol levels. By inducing a feeling of calm, yoga can lower the release of cortisol, a stress hor­mone that causes your body to release more glucose. Less unnecessary cortisol means fewer unnecessary elevations in blood sugar.” – Annie Kay

 

Diabetes is a major health issue. It is estimated that 30 million people in the United States and nearly 600 million people worldwide have diabetes and the numbers are growing. Type II Diabetes results from a resistance of tissues, especially fat tissues, to the ability of insulin to promote the uptake of glucose from the blood. As a result, blood sugar levels rise producing hyperglycemia. Diabetes is heavily associated with other diseases such as cardiovascular disease, heart attacks, stroke, blindness, kidney disease, and circulatory problems leading to amputations. As a result, diabetes doubles the risk of death of any cause compared to individuals of the same age without diabetes.

 

Type 2 diabetes is a common and increasingly prevalent illness that is largely preventable. One of the reasons for the increasing incidence of Type 2 Diabetes is its association with overweight and obesity which is becoming epidemic in the industrialized world. A leading cause of this is a sedentary life style. Unlike Type I Diabetes, Type II does not require insulin injections. Instead, the treatment and prevention of Type 2 Diabetes focuses on diet, exercise, and weight control. Recently, mindfulness practices have been shown to be helpful in managing diabetes. A mindfulness practice that combines mindfulness with exercise is yoga and it has been shown to be helpful in the treatment of Type II Diabetes.

 

In today’s Research News article “Effect of Yoga and Exercise on Glycemic Control and Psychosocial Parameters in Type 2 Diabetes Mellitus: A Randomized Controlled Study.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7336951/ ) Singh and Khandelwal recruited adult patients with Type 2 Diabetes and randomly assigned them to either an exercise or yoga practice group. Exercise was practiced for 30 minutes 5 days per week for 3 months and consisted of walking and moderate aerobic exercise combined with diet. The yoga group were trained in postures and breathing exercises for 2 weeks and then practiced at home for 3 months. They were measured before and after training for anxiety, depression, diabetes quality of life and self-efficacy. They also had blood drawn for assessment of glycemic control (HbA1c).

 

They found that following training both groups had significant decreases in anxiety, depression, and HbA1c and significant increases in diabetes quality of life and self-efficacy. But the yoga group had significantly better outcomes on all measures compared to the diet and exercise group.

 

These results suggest that practicing yoga is better for the psychological and physical health of patients with Type 2 Diabetes than non-yoga exercises. Yoga practice not only improved psychological health but also glycemic control suggesting better control of the disease. The fact that yoga was superior in effectiveness to non-yoga exercise is important as yoga is both a mindfulness practice and an exercise. So, the results suggest that adding mindfulness to exercise potentiates the programs effectiveness in treating patients with Type 2 Diabetes.

 

Hence, yoga is the preferred exercise for the treatment of Type 2 Diabetes.

 

“I recommend yoga primarily for stress management. Stress elevates blood sugar, which can lead to more diabetes complications. Yoga helps us center ourselves, and centering calms us and can help keep blood sugar levels balanced.” – Janet Zappe

Study Summary

Vijay Pratap Singh, Bidita Khandelwal. Effect of Yoga and Exercise on Glycemic Control and Psychosocial Parameters in Type 2 Diabetes Mellitus: A Randomized Controlled Study. Int J Yoga. 2020 May-Aug; 13(2): 144–151. Published online 2020 May 1. doi: 10.4103/ijoy.IJOY_45_19

 

Abstract

Context (Background):

Type 2 diabetes has been strongly associated with psychosocial factors such as stress, anxiety, depression, and quality of life (QOL). There is not much evidence whether yoga can improve these factors and motivate individuals to engage in active lifestyle.

Aims:

This study aims to evaluate the effect of yoga and exercise over glycemic control, anxiety, depression, exercise self-efficacy (ESE), and QOL after 3-month program.

Methods:

Two hundred and twenty-seven individuals were randomly allocated to yoga group (YG) and exercise group. YG practiced yoga for 2 weeks under supervision and then carried out practice at home for 3 months. The exercise group practiced 30 min of brisk walking for 5 days a week.

Results:

On comparison among the groups, in YG, there was a mean change of 0.47 in glycated hemoglobin which was greater than mean reduction of 0.28 in the exercise group with P < 0.05. State anxiety reduced by 7.8 and trait anxiety reduced by 4.4 in YG (P < 0.05) in 3 months as compared to nonsignificant reductions of 3 and 1 in mean of state and trait anxiety scores in the exercise group (P > 0.05). There was a statistically significant reduction in depression score in both the groups, 8.6 in yoga and 4.0 in exercise, which was greater in YG. ESE improved by 19.2 in YG (P < 0.05), whereas it improved only 2.2 in the exercise group (P > 0.05). QOL improved by 23.7 in YG and 3.0 in the exercise group which was nonsignificant in the exercise group as compared to YG.

Conclusions:

Yoga is superior to exercise alone as a lifestyle modification program in improving glycemic control, anxiety, depression, and QOL as well as ESE.

Improve Low Back Pain and Its Effects with Yoga Practice

Improve Low Back Pain and Its Effects with Yoga Practice

 

By John M. de Castro, Ph.D.

 

“If you’re dealing with back pain, yoga may be just what the doctor ordered. Yoga is a mind-body therapy that’s often recommended to treat not only back pain but the stress that accompanies it. The appropriate poses can relax and strengthen your body.” – Emily Cronkleton

 

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. 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. 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 combines mindfulness practice with exercise and has been shown to have a myriad of health benefits. Many forms of yoga focus on the proper alignment of the spine, which could directly address the source of back and neck pain for many individuals. Indeed, yoga has been shown to relieve chronic pain. Yoga practice has also been shown to be effective for the relief of chronic low-back pain. The research has been accumulating and it is useful to summarize what has been learned.

 

In today’s Research News article “Yoga compared to non-exercise or physical therapy exercise on pain, disability, and quality of life for patients with chronic low back pain: A systematic review and meta-analysis of randomized controlled trials.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7462307/ ) Zhu and colleagues review, summarize, and perform a meta-analysis of the effectiveness of yoga practice in comparison to other exercises for low back pain. They identified 18 randomized controlled trials.

 

They report that the published research found that yoga practice, in comparison to baseline and no-exercise controls, produced significant reductions in pain and functional disability that was still present 6 months after the completion of training. At 12 months, there was still a significant difference in functional disability but not pain. In comparison to physical therapy, yoga produced significantly greater pain reduction but not functional disability immediately after treatment but this difference disappeared at 4 weeks after the completion of training. Yoga practice did not produce significant improvements in the patients’ quality of life.

 

These results suggest that yoga practice is effective in improving pain and functional disability in patients with low back pain. Yoga practice appears to be as effective but not superior to physical therapy. Hence, the published research to date suggests that low back pain can be successfully treated with either yoga practice or physical therapy.

 

So, improve low back pain and its effects with yoga practice.

 

“Achy back? Give yoga a go. Numerous studies have shown the power of the ancient practice, which emphasizes stretching, strength, and flexibility, to relieve back soreness and improve function.” – Annie Houser

Feilong Zhu, Ming Zhang, Dan Wang, Qianqin Hong, Cheng Zeng, Wei Che. Yoga compared to non-exercise or physical therapy exercise on pain, disability, and quality of life for patients with chronic low back pain: A systematic review and meta-analysis of randomized controlled trials. PLoS One. 2020; 15(9): e0238544. Published online 2020 Sep 1. doi: 10.1371/journal.pone.0238544

 

Abstract

Background

Chronic low back pain (CLBP) is a common and often disabling musculoskeletal condition. Yoga has been proven to be an effective therapy for chronic low back pain. However, there are still controversies about the effects of yoga at different follow-up periods and compared with other physical therapy exercises.

Objective

To critically compare the effects of yoga for patients with chronic low back pain on pain, disability, quality of life with non-exercise (e.g. usual care, education), physical therapy exercise.

Methods

This study was registered in PROSPERO, and the registration number was CRD42020159865. Randomized controlled trials (RCTs) of online databases included PubMed, Web of Science, Cochrane Central Register of Controlled Trials, Embase which evaluated effects of yoga for patients with chronic low back pain on pain, disability, and quality of life were searched from inception time to November 1, 2019. Studies were eligible if they assessed at least one important outcome, namely pain, back-specific disability, quality of life. The Cochrane risk of bias tool was used to assess the methodological quality of included randomized controlled trials. The continuous outcomes were analyzed by calculating the mean difference (MD) or standardized mean difference (SMD) with 95% confidence intervals (CI) according to whether combining outcomes measured on different scales or not.

Results

A total of 18 randomized controlled trials were included in this meta-analysis. Yoga could significantly reduce pain at 4 to 8 weeks (MD = -0.83, 95% CI = -1.19 to -0.48, p<0.00001, I2 = 0%), 3 months (MD = -0.43, 95% CI = -0.64 to -0.23, p<0.0001, I2 = 0%), 6 to 7 months (MD = -0.56, 95% CI = -1.02 to -0.11, p = 0.02, I2 = 50%), and was not significant in 12 months (MD = -0.52, 95% CI = -1.64 to 0.59, p = 0.36, I2 = 87%) compared with non-exercise. Yoga was better than non-exercise on disability at 4 to 8 weeks (SMD = -0.30, 95% CI = -0.51 to -0.10, p = 0.003, I2 = 0%), 3 months (SMD = -0.31, 95% CI = -0.45 to -0.18, p<0.00001, I2 = 30%), 6 months (SMD = -0.38, 95% CI = -0.53 to -0.23, p<0.00001, I2 = 0%), 12 months (SMD = -0.33, 95% CI = -0.54 to -0.12, p = 0.002, I2 = 9%). There was no significant difference on pain, disability compared with physical therapy exercise group. Furthermore, it suggested that there was a non-significant difference on physical and mental quality of life between yoga and any other interventions.

Conclusion

This meta-analysis provided evidence from very low to moderate investigating the effectiveness of yoga for chronic low back pain patients at different time points. Yoga might decrease pain from short term to intermediate term and improve functional disability status from short term to long term compared with non-exercise (e.g. usual care, education). Yoga had the same effect on pain and disability as any other exercise or physical therapy. Yoga might not improve the physical and mental quality of life based on the result of a merging.

Meditation Improves Health and Well-Being Through Epigenetic Mechanisms

Meditation Improves Health and Well-Being Through Epigenetic Mechanisms

 

By John M. de Castro, Ph.D.

 

“It seems unusual that something as simple and easy as meditating could improve your health, but these studies demonstrate an epigenetic link between meditation and its potential disease-reducing benefits.” – Bailey Kirkpatrick

 

Over the last several decades, research and anecdotal experiences have accumulated an impressive evidential case that the development of mindfulness has positive benefits for the individual’s mental, physical, and spiritual life. Mindfulness appears to be beneficial both for healthy people and for people suffering from a myriad of illnesses. It appears to be beneficial across ages, from children to the elderly. And it appears to be beneficial across genders, personalities, race, and ethnicity. The breadth and depth of benefits is unprecedented.

 

Meditation practice has been shown to improve health and longevity. One way it appears to act is by altering the genes which govern cellular processes in our bodies. The genes dictate all of the chemical processes in our bodies including immune and inflammatory responses. The ability of outside influences to affect gene expression is known as epigenetics. There have been a number of research studies of the of the epigenetic effects of mindfulness practices. So, it makes sense to summarize what has been learned regarding the epigenetic alterations in gene expressions produced by mindfulness practices to determine if these effects are the intermediary between meditation and health.

 

In today’s Research News article “Molecules of Silence: Effects of Meditation on Gene Expression and Epigenetics.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7431950/) Venditti and colleagues review and summarize the published research studies of the effects of mindfulness on gene expression.

 

They report that the published research found that sitting and walking meditation, Tai Chi, and Yoga produce wide-ranging changes in gene expression including slowing of the age-related methylation of the genes. They report that the epigenetic changes seen alter genes involved in metabolism, inflammatory processes, oxidative stress, and DNA damage response. In fact, they report that mindfulness practices produce epigenetic changes that are the opposite to those produced by stress.

 

These findings are important for understanding the ability of mindfulness practices to promote health and slow the aging process. By reversing the changes that stress produces in gene expression, mindfulness practices can prevent or reverse the harmful consequences of stress on the body. This may well be one of the mechanisms that underlie the health benefits of mindfulness practices.

 

So, meditation improves health and well-being through epigenetic mechanisms.

 

“a single 8-hour mindfulness meditation retreat can rapidly alter methylation levels that affect epigenetic expression in genes among experienced meditators. Involved genes include those that regulate inflammation, immune cell metabolism, DNA repair, cellular aging, RNA metabolism, protein translation, cell adhesion, and neurotransmission.” – AMRA

Abstract

Many studies have consistently demonstrated an epigenetic link between environmental stimuli and physiological as well as cognitive responses. Epigenetic mechanisms represent a way to regulate gene activity in real time without modifying the DNA sequence, thus allowing the genome to adapt its functions to changing environmental contexts. Factors such as lifestyle, behavior, and the practice of sitting and moving mindful activities have been shown to be important means of environmental enrichment. Such practices, which include mindfulness meditation, Vipassana, Yoga, Tai Chi, and Quadrato Motor Training, have been reported to positively impact well-being. In fact, they can be considered emotional and attentional regulatory activities, which, by inducing a state of greater inner silence, allow the development of increased self-awareness. Inner silence can therefore be considered a powerful tool to counteract the negative effects of overabundant environmental noise, thanks to its power to relieve stress-related symptoms. Since all these positive outcomes rely on physiological and biochemical activities, the molecular and epigenetic mechanisms influenced by different mindful practices have recently started to be investigated. Here, we review some of the findings that could allow us to uncover the mechanisms by which specific practices influence well-being.

Improve Physiological Adaptation to High Altitude with Yoga and Meditation

Improve Physiological Adaptation to High Altitude with Yoga and Meditation

 

By John M. de Castro, Ph.D.

 

“Pranayama techniques allow for maximizing your lung capacity, which becomes critical at high altitudes.” – D.. M. Kumar

 

Breathing is essential for life and generally occurs automatically. It’s easy to take for granted as it’s been there our entire lives. Nevertheless, we become more aware of it when it varies with circumstances, such as when we exercise, in emotional states, especially fear and anxiety, and at high altitude. Breathing exercises are common in yoga practices and have been found to have a number of beneficial effects. High altitude taxes the physiology and particularly the respiratory system. Since yoga practice can improve respiratory function, it would be expected that yoga practice would improve the physiological adaptations needed to function at high altitude.

 

In today’s Research News article “Effect of mindfulness meditation protocol in subjects with various psychometric characteristics at high altitude.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7218243/) Bhanushali and colleagues recruited adults with no prior Kriya Yoga experience and provided them with an intensive 4-day 15 hours per day practice of Kriya Yoga at high altitude (11,500 ft.). The practice consisted of a combination of meditation and yoga. They were measured before and after training for body size, blood pressure, oxygen saturation, cholesterol, triglycerides, psychometric constitution (prakriti), attention, memory, verbal fluency, executive functioning, and information processing speed, anxiety, mental well-being, and happiness.

 

They found that in comparison to baseline, after the Kriya Yoga practice there were significant increases in oxygen saturation, blood glucose, mental well-being and happiness and significant decreases in anxiety, blood triglycerides and very low-density lipoprotein. Hence, after training there were improvements in physical and psychological well-being.

 

These results must be interpreted cautiously as there wasn’t a control comparison condition. So, the results could be due to acclimatization over the 4 days at high altitude and not to the Kriya Yoga practice. Also, without a control condition, participant expectancy effects (placebo), experimenter bias, attentional effects etc. may be responsible for the results. In addition, there was no comparison to other exercises. So, the effects may be due to exercise and not specifically to Kriya Yoga.

 

Taking this into consideration, the results demonstrate that intensive yoga practice can be conducted at high altitude and shows potential for improving physical and psychological acclimatization to high altitude.

 

So, improve physiological adaptation to high altitude with yoga and meditation.

 

“BREATHE — the universal mantra of yoga. This can be a bit harder than normal at thousands feet above sea level. There’s 20 percent less oxygen (or more!) in the air at these elevations. You may experience headache, fatigue, dizziness, nausea, shortness of breath, and sleep disturbance (and sleep is oh-so-important). If you’re feeling like you’re suffering from a bad hangover or the flu, chances are your body is struggling to adapt to the change in altitude.”.- Vicki Kahn

Bhanushali, D., Tyagi, R., Limaye Rishi Nityapragya, N., & Anand, A. (2020). Effect of mindfulness meditation protocol in subjects with various psychometric characteristics at high altitude. Brain and behavior, 10(5), e01604. https://doi.org/10.1002/brb3.1604

 

Abstract

Introduction

Incidence of high altitude‐related sickness is increasing due to more number of people visiting the areas of high altitude which may result in life‐threatening conditions including acute mountain sickness (AMS), high altitude pulmonary edema (HAPE), high altitude cerebral edema (HACE), and High‐altitude pulmonary hypertension (HAPH). We hypothesized that an advanced yoga regimen may be beneficial in dealing with the physiology of acclimatization.

Methods

Anthropometric, Biochemical, and Psychological assessments were carried out in 48 participants before and after the advance meditation program (AMP) in the experimental group. Individuals with an age range of 20–65 years with no comorbidities were included in the study. Participants were exposed to AMP for 4 days. All assessments were carried out at the baseline and after the course. Prakriti was constituted for all participants using a standard questionnaire. The study was carried out after obtaining the written informed consent as per the guidelines outlined by the Institute Ethics Committee.

Results

Po2 and glucose levels were found significantly reduced along with changes in the Happiness index, anxiety, and mental well‐being. However, participants with lowered Po2, after 4 days of mindfulness intervention, showed a positive outcome measured by the established scales of anxiety, happiness, and information processing. Psychometric or Prakriti wise analysis revealed that subject with “Pitta” constitution exposed to high altitude and advance meditation showed changes in more parameters than “Vatta” or “Kapha” Constitution.

Conclusions

Advance meditation in the high altitude zone confers biochemical and neuro‐cognitive benefits. Molecular studies may require to understand the role of hypoxic condition in improving the disease state.
