“Respiration is our primary and most important movement pattern … and also the most dysfunctional.” – Karel Lewit

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 and also in emotional states, especially fear and anxiety. But we rarely notice it during everyday ongoing life. Yet, its characteristics are associated with our state of well-being. Slow deep breathing is characteristic of a healthy relaxed state. Breathing exercises are common in yoga practices and have been found to have a number of beneficial effects.

Yoga practice contains a number of different components that are mixed in varying combinations in different yoga practices. They consist of postures, meditation, relaxation, breathing exercises, and chanting. This presents a challenge in interpreting the beneficial effects of yoga practice. It is difficult to determine which component or which combination of components is required for the benefits.

In today’s Research News article “Positive Effects of Yoga on Physical and Respiratory Functions in Healthy Inactive Middle-Aged People.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6329219/ ), and colleagues examine the effects of yogic postures and the added benefits of yogic breathing in improving respiratory function in healthy inactive middle-aged people. They recruited inactive non-smoking adults aged 40 to 60 years who were not yoga practitioners and randomly assigned them to receive either training in yoga postures or training in yoga postures plus yogic breathing training. Training occurred in a 70-minute session once a week for 8 weeks. Participants were also provided a DVD for a 7-minute home exercises twice a week. They were measured before and after training for body size and composition, muscle endurance, resting heart rate, flexibility, respiratory function, and respiratory muscle strength.

They found both groups after training had significant improvements in muscle endurance, resting heart rate, and upper extremity flexibility. But only the group that had additional breathing exercises had significant improvements in lower extremity flexibility. Both groups had significant improvements in overall pulmonary function, including vital capacity, forced vital capacity, forced expiratory volume, and peak expiratory flow rate. But only the group that had additional breathing exercises had significant improvements in respiratory muscle strength and maximum inspiratory pressure.

The results demonstrated that yoga practice produces improvements in strength and flexibility and in respiratory function. But, adding breathing exercises produces additional benefits in flexibility and respiratory function. The study did not include a control group that performed a different exercise with equivalent intensity. So, it can’t be determined whether the physical improvements were specific to yoga or would have occurred with any equivalent exercise. But they do suggest that practicing yoga has physical benefits for strength, flexibility, and respiratory function, and including yogic breathing exercises helps to maximize the effectiveness of the yoga practice.

So, improve physical and respiratory function with yoga.

“yoga breathing: pranayama. It’s the art of breathing. Taking breathing to the next level. Learning different breathing techniques can add more beneficial oxygen to our bodies, aid in digestion, hone our concentration skills, calm our nerves, and much more.” – Gaiam

Abstract

Context:

Yoga improves physical and respiratory functions in healthy inactive middle-aged people.

Aim:

This study aimed to assess the effects of 8 weeks of asana and asana with pranayama lessons in order to clarify the influence of two different combinations of yoga practice on physical and respiratory functions in healthy inactive middle-aged people.

Subjects and Methods:

A total of 28 participants (mean age: 52.7 years) were divided into a yoga asana (YA) group and YA with pranayama (YAP) group. Participants attended a 70-min session once a week for 8 weeks. The YA group practiced basic asana without specific breathing instructions, while the YAP group practiced basic asanawith specific breathing instructions (pranayama). Respiratory function was measured with an autospirometer. Physical function assessments included the 30-s chair stand test and upper and lower extremity flexibility. All tests were assessed at baseline and after 8 weeks of intervention.

Statistical Analysis:

Changes in scores were analyzed with the paired t-test for each group. Pre-post results were compared for all the measured values. P < 0.05 was considered statistically significant.

Results:

Both groups showed significant improvements in physical and overall respiratory functions after the 8-week yoga intervention. However, the maximal inspiratory pressure and lower extremity flexibility improved only in the YAP group.

Conclusions:

The 8-week yoga intervention for healthy inactive middle-aged people improved the overall respiratory and physical functions, and the inclusion of pranayama had the added benefit of improving inspiratory muscle strength and global body flexibility.

Improve Physiological Relaxation in Children with Autism Spectrum Disorder with Yoga

By John M. de Castro, Ph.D.

“mindfulness has emerged as a way of treating children and adolescents with conditions ranging from ADHD to anxiety, autism spectrum disorders, depression and stress. And the benefits are proving to be tremendous.” – Juliann Garey

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, and is frequently associated with sleep and gastrointestinal problems. ASD is a serious disorder that impairs the individual’s ability to lead independent lives including complete an education, enter into relationships or find and hold employment. It is also difficult and stressful for the caregivers.

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). 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 alternative treatment options. A promising treatment is mindfulness training. It has been shown to be helpful in treating ASD.

A characterizing feature of ASD is dysfunction in the Autonomic Nervous System (ANS) which is composed of 2 divisions. The sympathetic division underlies activation while the parasympathetic division underlies relaxation. When these divisions are out of balance the individual may be overly stressed or overly sedentary. Appropriate balance is important for health and well-being. A measure of balance is provided by the variability of the heart rate. Moderated heart rate variability reflects balance in the autonomic nervous system. So, changes in heart rate variability may be a good measure of relief of ASD by Yoga practice.

In today’s Research News article “Effect of Yoga Intervention on Short-Term Heart Rate Variability in Children with Autism Spectrum Disorder.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6329223/ ), Vidyashree and colleagues recruited children aged 8 to 14 years who were diagnosed with Autism Spectrum Disorder. All the children participated in continuing physical rehabilitation training. They were randomly assigned to receive either an additional 40-minute daily yoga practice for 3 months or no additional treatment. Yoga practice consisted of postures and chanting. The children were measured for the variability of their heart rate over 15 minutes with an electrocardiagram (ECG) measurement.

They found that after the 3 months of yoga practice there was a significant reduction in the resting heart rate of the children. Importantly, they found that a number of measures of heart rate variability were significantly improved in the children who practiced yoga including low frequency to high frequency ratio signaling a modulation of autonomic nervous system (ANS) activity. This signals a reduction in sympathetic activation and an increase in parasympathetic relaxation.

These findings suggest that yoga practice may significantly reduce imbalance in the ANS that characterizes children with Autism Spectrum Disorder (ASD). It is possible that this modulation may underlie the ability of yoga practice in improving ASD. There is a need for more research on this question. But the results are suggestive that yoga practice may be a beneficial treatment for children with ASD.

So, improve physiological relaxation in children with Autism Spectrum Disorder with yoga.

“mindfulness practices may be a viable technique in not only improving behavioral and cognitive responses in those with ASD, but also the overall well-being of their caregivers.” – Krupa Patel

Study Summary

Vidyashree, H. M., Maheshkumar, K., Sundareswaran, L., Sakthivel, G., Partheeban, P. K., & Rajan, R. (2019). Effect of Yoga Intervention on Short-Term Heart Rate Variability in Children with Autism Spectrum Disorder. International journal of yoga, 12(1), 73-77.

Abstract

Background:

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by impairment in social interactions, communication, restricted, and repetitive behaviors. Evidence-based treatment options for ASD are limited. Yoga is practiced by over 20 million people worldwide, and multiple studies have investigated yoga as a possible effective intervention for children with ASD.

Aim:

The aim of this study is to investigate the effect of yoga intervention on short-term heart rate variability (HRV) in children with ASD.

Methodology:

In this study, 50 children (38 boys and 12 girls) with ASD were recruited from Swabhimaan Trust, Palavakkam, Chennai. They were randomly grouped into ASD with yoga intervention group (n = 25) and ASD without yoga intervention group (n = 25) by simple lottery method. Yoga group children underwent yoga training for 3 months, and the control group did not receive any such training. For short-term HRV, 15 min electrocardiogram recording in sitting posture was recorded in lead II using a simple analog amplifier.

Results:

In HRV, time domain parameters such as mean RR interval (0.72 [0.74] to 0.94 [0.92]), standard deviation of the NN intervals (52.04 [54.23] to 74.48 [72.80]), and root of the mean squared differences of successive NN interval (32.60 [34.40] to 40.83 [42.90]) significantly increased in ASD children after yoga intervention. In frequency-domain parameters, high frequency (HF) in n. u (48.08 [47.24] to 58.37 [59.22]) shows a significant increase and low frequency (LF) in n. u (52.4 [51.82] to 40.51 [40.12]), and LF/HF ratio (1.29 [1.31] to 0.78 [0.79]) shows a significant decrease in ASD with yoga intervention group children after 3 months of yoga training.

Conclusion:

Yoga interventions have been successful in bringing parasympathetic dominance in ASD children, and the greater advantage is being a noninvasive way of intervention to support children with ASD and help them to achieve physiological as well as psychological balance.

Improve Severe Mental Illness with Yoga and Mindfulness

Improve Severe Mental Illness with Yoga and Mindfulness

By John M. de Castro, Ph.D.

“yoga does in fact have positive effects on mild depression and sleep problems, and it improves the symptoms of psychiatric disorders like schizophrenia and ADHD among patients using medication.” – Alexandra Sifferin

Psychoses are mental health problems that cause people to perceive or interpret things differently from those around them. This might involve hallucinations; seeing and, in some cases, feeling, smelling or tasting things that aren’t objectively there, or delusions; unshakable beliefs that, when examined rationally, are obviously untrue. The combination of hallucinations and delusional thinking can often severely disrupt perception, thinking, emotion, and behavior, making it difficult if not impossible to function in society without treatment. Psychoses appear to be highly heritable and involves changes in the brain. Psychoses are very difficult to treat with psychotherapy and are usually treated with antipsychotic drugs. These drugs, however, are not always effective, sometimes lose effectiveness, and can have some difficult side effects. Hence, there is a need for safe and effective alternative treatments for psychosis.

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 antidepressant 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.

Clearly, there is a need for treatment alternatives that can be effective alone or in combination with drugs. Both mindfulness and yoga training has been shown to be beneficial for patients with psychosis and with major depression. It is important at this point to step back and review the published studies of the application of mindfulness and yoga practices for the treatment of severe mental illnesses, In today’s Research News article “Role of Yoga and Mindfulness in Severe Mental Illnesses: A Narrative Review.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6329226/ ), Sathyanarayanan and colleagues review and summarize 49 published research studies on the effectiveness of mindfulness and yoga practices for the treatment of severe mental illnesses.

They report that the research finds that both mindfulness practices and yoga practice in combination with antipsychotic medications significantly reduces both the positive and negative symptoms of schizophrenia and other psychotic disorders, improves the patient’s ability to effectively engage in everyday activities and also improves higher level thought processes, cognition. With Bipolar Disorder they report that there are only a very small number of studies that suggest improvements but more research is needed. With Major Depressive Disorders both mindfulness and yoga practices have been shown to produce significant reductions in depression alone or in combination with anti-depressive medications.

Hence, they find that the current published research supports the use of either mindfulness or yoga practices for the treatment of severe mental illnesses. There is clearly a need for more research, but the studies to date are very encouraging. They suggest that these practices are safe and effective whether used alone or in combination with drugs and may then be a needed alternative treatment to drugs.

So, improve severe mental illness with yoga and mindfulness.

Study Summary

Sathyanarayanan, G., Vengadavaradan, A., & Bharadwaj, B. (2019). Role of Yoga and Mindfulness in Severe Mental Illnesses: A Narrative Review. International journal of yoga, 12(1), 3-28.

Abstract

Background:

Yoga has its origin from the ancient times. It is an integration of mind, body, and soul. Besides, mindfulness emphasizes focused awareness and accepting the internal experiences without being judgemental. These techniques offer a trending new dimension of treatment in various psychiatric disorders.

Aims:

We aimed to review the studies on the efficacy of yoga and mindfulness as a treatment modality in severe mental illnesses (SMIs). SMI includes schizophrenia, major depressive disorder (MDD), and bipolar disorder (BD).

Methods:

We conducted a literature search using PubMed, Google Scholar, and Cochrane Library with the search terms “yoga,” “meditation,” “breathing exercises,” “mindfulness,” “schizophrenia spectrum and other psychotic disorders,” “depressive disorder,” and “bipolar disorder” for the last 10-year period. We also included relevant articles from the cross-references.

Results:

We found that asanas and pranayama are the most commonly studied forms of yoga for schizophrenia. These studies found a reduction in general psychopathology ratings and an improvement in cognition and functioning. Some studies also found modest benefits in negative and positive symptoms. Mindfulness has not been extensively tried, but the available evidence has shown benefits in improving psychotic symptoms, improving level of functioning, and affect regulation. In MDD, both yoga and mindfulness have demonstrated significant benefit in reducing the severity of depressive symptoms. There is very sparse data with respect to BD.

Conclusion:

Both yoga and mindfulness interventions appear to be useful as an adjunct in the treatment of SMI. Studies have shown improvement in the psychopathology, anxiety, cognition, and functioning of patients with schizophrenia. Similarly, both the techniques have been established as an effective adjuvant in MDD. However, more rigorously designed and larger trials may be necessary, specifically for BD.

Improve Type 2 Diabetes with Yoga

Improve Type 2 Diabetes with Yoga

By John M. de Castro, Ph.D.

“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

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. Hence, there is a need to step back and review what has been learned regarding the effectiveness of yoga practice for Type 2 Diabetes.

In today’s Research News article “The effects of yoga among adults with type 2 diabetes: A systematic review and meta-analysis.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5653446/ ), Thind and colleagues review summarize and perform a meta-analysis of the published research literature of the effectiveness of yoga practice for Type 2 Diabetes. They identified 23 published studies that included a control group.

They found that the research studies reported that compared to control participants, the patients who practiced yoga had significantly lower blood glucose levels and significantly improved glycemic control as evidenced by blood levels of HbA1c and/or FBG. The yoga participants also had significantly improved blood fat levels including lower levels of total cholesterol, very-low density lipoprotein, low-density lipoprotein, and triglyceride levels and increased high-density lipoprotein levels. In addition, the after yoga training the patients had significantly lower blood pressure and body mass index, and lower levels of the stress hormone cortisol.

These are remarkable findings, but most of these studies did not contain an active exercise control condition. So, the great benefits of yoga practice may be due to the physical exercise provided by yoga rather than anything specific to yoga. More research is needed to clarify this point. But, regardless, yoga practice has important benefits for adult patients with Type 2 Diabetes improving blood glycemic and lipid control, lowering blood pressure, body size, and stress hormone levels.

So, improve Type 2 Diabetes with Yoga.

“But yoga’s benefits for those with diabetes aren’t just physical: the process can help patients with the condition or its pre-indicators on more fundamental levels as well. By calming the awareness and integrating the mind with the body, yoga can relieve the daily stresses that often lie at the heart of diabetic symptoms.” – YogaU

Abstract

The purpose of this meta-analysis was to examine the effects of yoga for glycemic control among adults with type 2 diabetes (T2DM). Comprehensive electronic databases searches located 2559 unique studies with relevant key terms. Studies were included if they (1) evaluated a yoga intervention to promote T2DM management, (2) used a comparison group, (3) reported an objective measure of glycemic control at post-intervention, and (4) had follow-up length or post-test of at least 8 weeks from baseline. Independent raters coded participant, design and methodological characteristics and intervention content. Summary effect sizes and 95% confidence intervals (CI) were calculated. Twenty-three studies with 2473 participants (mean age = 53 years; 43% women) met eligibility criteria. Compared with controls, yoga participants were successful in improving their HbA1c (d + = 0.36, 95% CI = 0.16, 0.56; k = 16), FBG (d+ = 0.58, 95% CI = 0.40, 0.76; k = 20), and PPBG (d + = 0.40, 95% CI = 0.23, 0.56; k = 14). Yoga was also associated with significant improvements in lipid profile, blood pressure, body mass index, waist/hip ratio and cortisol levels. Overall, studies satisfied an average of 41% of the methodological quality (MQ) criteria; MQ score was not associated with any outcome (Ps > 0.05). Yoga improved glycemic outcomes and other risk factors for complications in adults with T2DM relative to a control condition. Additional studies with longer follow-ups are needed to determine the long-term efficacy of yoga for adults with T2DM.

Reduce Stress and Improve Autonomic Nervous System Function with Tai Chi or Yoga

March 15, 2019May 11, 2020 psyjdc 1 Comment

Reduce Stress and Improve Autonomic Nervous System Function with Tai Chi or Yoga

By John M. de Castro, Ph.D.

“The rate of individuals suffering from autonomic nervous system dysfunctions is fast on the rise, due to our high stress and stimulative 21st-century lifestyles. However unknown to many practitioners, there are several natural therapies which are proven to help support the balance of the autonomic nervous system such as meditation and often have fewer side-effects and are better tolerated than many pharmaceutical medications.” – NaturalHealthBlogger

There is an accumulating volume of research findings to demonstrate that Mind-body practices have highly beneficial effects on the health and well-being of humans. These include yoga, tai chi, and qigong, among many others. Because of their proven benefits the application of these practices to relieving human suffering has skyrocketed. Tai Chi has been practiced for thousands of years with benefits for health and longevity. Tai Chi training is designed to enhance function and regulate the activities of the body through regulated breathing, mindful concentration, and gentle movements. 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.

One way that these Mind-body practices may have their beneficial effects is by providing balance in the autonomic nervous system. The sympathetic division underlies activation while the parasympathetic division underlies relaxation. When these divisions are out of balance the individual may be overly stressed or overly sedentary. Appropriate balance is important for health and well-being. A measure of balance is provided by the variability of the heart rate. Moderated heart rate variability reflects balance in the autonomic nervous system.

In today’s Research News article “Effects of Mind⁻Body Exercises (Tai Chi/Yoga) on Heart Rate Variability Parameters and Perceived Stress: A Systematic Review with 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/PMC6262541/ ), Zou and colleagues review, summarize and perform a meta-analysis of the published randomized controlled trials investigating the effects of tai chi and yoga on a measure of autonomic balance; heart rate variability. They discovered 17 research publications reporting on research studies of fair to high quality.

They report that after both tai chi or yoga practice there are large significant reductions in perceived stress levels. Also, after practice there were small, albeit significant reductions in the normalized low-frequency component of heart rate variation and the ratio of low frequency to high frequency variations and significant increases in the normalized high-frequency component. These components are thought to be indicative of sympathetic and vagal modulation, sympathetic modulation, and sympathetic activity. These effects on heart rate variation components suggest that after tai chi and yoga practice there is better balance in the autonomic nervous system. Additionally, the published studies indicate that while both tai chi and yoga practice decrease stress and improve autonomic balance, that a minimum of 90 minutes per week of yoga practice produces better results.

These results are interesting and important. They suggest that tai chi and especially yoga practice promote health and well-being and may do so by reducing perceived levels of stress and balancing the autonomic nervous system. Yoga practice is generally a more intense exercise and it is likely that this greater intensity of exercise is responsible for yoga’s superiority. But Tai Chi is gentle, safe, and easily practiced conveniently without a professional teacher. Hence, it may be better adapted to integration into the daily lifestyle of the individual.

So, reduce stress and improve autonomic nervous system function with tai chi or yoga.

“Practicing yoga is an excellent way to stimulate and bring circuitry to the important parasympathetic nervous system. The gentle movements and slow rhythmic breathing slow the heart and blood pressure. Yoga redirects blood flow to the reproductive and digestive organs. Regular yoga practice results in a sustained state of strength and health, as well as mind and body balance. Tai Chi is widely used for its variety of health benefits and its adaptability to any age or level of fitness. It is an effective technique that enhances your body’s ability to use the mind to get in touch with the body through the nervous system. The results of continued practice include increased awareness, strengthened nerves, and better coordination, to name a few.” – Aleksandra Eifler

Effects of Mind⁻Body Exercises (Tai Chi/Yoga) on Heart Rate Variability Parameters and Perceived Stress: A Systematic Review with Meta-Analysis of Randomized Controlled Trials. Journal of clinical medicine, 7(11), 404. doi:10.3390/jcm7110404

Abstract

Background: Heart rate variability (HRV) as an accurate, noninvasive measure of the Autonomous Nervous System (ANS) can reflect mental health (e.g., stress, depression, or anxiety). Tai Chi and Yoga (Tai Chi/Yoga), as the most widely practiced mind–body exercises, have shown positive outcomes of mental health. To date, no systematic review regarding the long-lasting effects of Tai Chi/Yoga on HRV parameters and perceived stress has been conducted. Objective: To critically evaluate the existing literature on this topic. Methods: Five electronic databases (Web of Science, PubMed, Scopus, SportDiscus and Cochrane Library) were searched from the start of the research project to July 2018. Study selection, data extraction, and study quality assessment were independently carried out by two reviewers. The potentially identified randomized controlled trials (RCT) reported the useful quantitative data that were included only for meta-analysis. Results: meta-analysis of 17 medium-to-high quality RCTs showed significantly beneficial effects on HRV parameters (normalized low-frequency, Hedge’s g = −0.39, 95% CI −0.39 to −0.56, p < 0.001, I2 = 11.62%; normalized high-frequency, Hedge’s g = 0.37, 95% CI 0.22 to −0.52, p < 0.001, I2 = 0%; low-frequency to high-frequency ratio, Hedge’s g = −0.58, 95% CI −0.81 to −0.35, p < 0.001, I2 = 53.78%) and stress level (Hedge’s g = −0.80, 95% CI −1.17 to −0.44, p < 0.001, I2 = 68.54%). Conclusions: Stress reduction may be attributed to sympathetic-vagal balance modulated by mind–body exercises. Tai Chi/Yoga could be an alternative method for stress reduction for people who live under high stress or negative emotions.

Improve Psychomotor Perform of Intellectually Disabled Children with Yoga

By John M. de Castro, Ph.D.

“Special needs experts agree that yoga activities make a positive impact on individuals with special needs. These activities improve mobility, strength, and digestion for individuals with disabilities.” – Cara Batema

Intellectual disabilities involve below average intelligence and relatively slow learning. They are quite common, affecting an estimated 10% of individuals worldwide. These disabilities present problems for the children in learning mathematics, reading and writing. These difficulties, in turn, affect performance in other academic disciplines. The presence of intellectual disabilities can have serious consequences for the psychological well-being of the children, including their self-esteem and social skills. In addition, anxiety, depression, and conduct disorders often accompany learning disabilities. Not as well known is that children with intellectual disabilities also have motor problems.

Mindfulness training has been shown to improve attention, memory, and learning and increase success in school. Exercise has been shown to improve psychomotor performance in children with intellectual disabilities. Yoga is both a mindfulness practice and an exercise that also tends to improve motor ability. So, it would make sense to explore the application of yoga training for the treatment of children with intellectual disabilities.

In today’s Research News article “Effect of yoga practices on psycho-motor abilities among intellectually disabled children.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6165980/ ), Pise and colleagues recruited children aged 10 to 15 years from a school for the intellectually disabled. They were randomly assigned to a no-treatment control group or to receive yoga training for 1 hour per day, 5 days per week, for 12 weeks. The practice consisted of relaxation, postures, breathing exercises, and meditation. They were measured before and after training for balance, eye-hand coordination, agility, and reaction time.

They found that in comparison to baseline after the yoga training there were significant increases balance, eye-hand coordination, and agility, and decreases in reaction time. In comparison to the no treatment control group, the yoga group after training had significantly greater balance and faster reaction times. Hence, yoga practice appears to improve motor performance in children with intellectual disabilities.

These results were obtained with a no-treatment control condition. They need to be repeated with an active control condition such as a different exercise to determine if it was yoga practice itself or the exercise provided by yoga practice that was responsible for the improvements. But, nonetheless, the results suggest that yoga practice may be beneficial for children with intellectual disabilities. Improved motor ability might affect their performance in activities and sports and thereby improve their self-esteem.

So, improve psychomotor perform of intellectually disabled children with yoga.

“Yoga for special needs classes provide a sense of belonging and community. These adaptive yoga classes focus on building strength, developing regulation skills through breathing, improving mobility and maintaining/improving overall health and emotional well-being.” – Project Yoga

Study Summary

Pise, V., Pradhan, B., & Gharote, M. (2018). Effect of yoga practices on psycho-motor abilities among intellectually disabled children. Journal of exercise rehabilitation, 14(4), 581-585. doi:10.12965/jer.1836290.145

Abstract

The children with intellectual disabilities show disorders at motor development and coordination. Hence, the objective of this study was to see the effect of yoga practices on psycho-motor abilities of intellectually disabled children. Seventy intellectually disabled children were divided into experimental group and control group. Both experimental and control group were assessed on the first day and after 12 weeks of the yoga intervention for static balance, eye hand coordination, agility and reaction time. The subjects of experimental group then underwent a training of yoga practices, for 1 hr for a total period of 12 weeks. The result of within group comparison revealed significant improvement in static balance, eye hand coordination, agility, and reaction time (P< 0.001) in subjects of yoga group however no change was observed in control group. The present study demonstrated that 12 weeks of yoga is effective in improving psycho-motor abilities of intellectually disabled children.

Improve Treatment Resistant Major Depression with Yoga

By John M. de Castro, Ph.D.

“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.” – Amanda MacMillan

Clinically diagnosed depression is the most common mental illness, affecting over 6% of the population. Major depression can be quite debilitating. Depression can be difficult to treat and 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. Yoga practice is a mindfulness training and has the added benefit of being an exercise which has been also found to be effective for depression.

Recently, it has been discovered that there are genetic differences between patients with major depression who respond to antidepressant drugs and those who don’t. In particular non-responders appear to have a 5-HTTLPR variant of the serotonin transporter gene (SLC6A4) and MTHFR 677C>T polymorphisms. The serotonin system in the brain is a target of antidepressant drugs and these genetic variants may underlie non-responsiveness to the drugs. Since, yoga practice appears to be effective for depression in patients who do not respond to antidepressant drugs, it is likely that yoga practice works in spite of these genetic variants.

In today’s Research News article “5-HTTLPR and MTHFR 677C>T polymorphisms and response to yoga-based lifestyle intervention in major depressive disorder: A randomized active-controlled trial.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6278208/ ), Tolahunase and colleagues recruited patients with major depressive disorder and randomly assigned them to receive either a 12-week yoga program or to receive antidepressant drugs (SSRIs). Yoga was practiced for 2 hours per day, 5 days per week, for 12 weeks and consisted of postures, breathing exercises, and meditation. They were measured before and after treatment for depression, other psychiatric conditions, and childhood trauma. Blood was drawn for DNA genotyping.

They found that both groups had significant reductions in depression over the treatment period, but, the yoga group had significantly greater reductions in depression and higher remission rates (59% compared to 33%) than the antidepressant drug group. The participants with 5-HTTLPR and MTHFR 677C>T polymorphisms had significantly lower reductions in depression and remission rates in the antidepressant drug group but not in the yoga group. The participants in the yoga group with the polymorphisms benefited with reductions in depression and increases in remission rates to the same extent as those without the polymorphisms.

These are remarkable results. Yoga practice produced greater relief of depression than antidepressant drugs and, in addition, yoga practice produced this relief irrespective of the genetic polymorphisms that affect responses to antidepressant drugs. This suggests that yoga practice my work to relieve depression through a different mechanism than antidepressant drugs. Hence, yoga practice appears to be an almost ideal treatment for major depressive disorder, producing high remission rates and great reductions in depression, safely, without major side effects, and irrespective of the genetic polymorphisms that reduce responsiveness to antidepressant drugs. This suggests that yoga practice should be the first line treatment for major depressive disorder.

So, improve treatment resistant major depression with yoga

“many patients dealing with depression, anxiety, or stress, yoga may be a very appealing way to better manage symptoms. Indeed, the scientific study of yoga demonstrates that mental and physical health are not just closely allied, but are essentially equivalent. The evidence is growing that yoga practice is a relatively low-risk, high-yield approach to improving overall health.” – Harvard Mental Health Newsletter

Study Summary

Tolahunase, M. R., Sagar, R., & Dada, R. (2018). 5-HTTLPR and MTHFR 677C>T polymorphisms and response to yoga-based lifestyle intervention in major depressive disorder: A randomized active-controlled trial. Indian journal of psychiatry, 60(4), 410-426.

Abstract

Background:

There is growing evidence suggesting that both genetic and environmental factors modulate treatment outcome in, a highly heterogeneous, major depressive disorder (MDD). 5-HTTLPR variant of the serotonin transporter gene (SLC6A4) and MTHFR 677C>T polymorphisms have been linked to the pathogenesis of MDD, and antidepressant treatment response. The evidence is lacking on the clinical utility of yoga in patients with MDD who have 5-HTTLPR and MTHFR 677C>T polymorphisms and less likely to respond to medications (SSRIs).

Aims:

We aimed to examine the impact of YBLI in those who have susceptible 5-HTTLPR and MTHFR 677C>T polymorphisms and are less likely to drug therapy with SSRIs.

Settings and Design:

In a 12 week randomized active-controlled trial, MDD patients (n = 178) were randomized to receive YBLI or drug therapy.

Methods:

Genotyping was conducted using PCR-based methods. The clinical remission was defined as BDI-II score ≤ 9.

Statistical Analysis Used:

An intent-to-treat analysis was performed, and the association of genotype with treatment remission consisted of the logistic regression model. A P value of <0.05 was considered statistically significant.

Results:

Multivariate logistic regression models for remission including either 5-HTTLPR or MTHFR 677C>T genotypes showed statistically significant odds of remission in YOGA arm vs. DRUG arm. Neither 5-HTTLPR nor MTHFR 677C>T genotype showed any influence on remission to YBLI (P = 0.73 and P = 0.64, respectively). Further analysis showed childhood adversity interact with 5-HTTLPR and MTHFR 677C>T polymorphisms to decrease treatment response in DRUG treatment arm, but not in YOGA arm.

Conclusions:

YBLI provides MDD remission in those who have susceptible 5-HTTLPR and MTHFR 677C>T polymorphisms and are resistant to SSRIs treatment. YBLI may be therapeutic for MDD independent of heterogeneity in its etiopathogenesis.

Improve Physical and Mental Health with Musculoskeletal Disorders with Mindfulness Practices

Improve Physical and Mental Health with Musculoskeletal Disorders with Mindfulness Practices

By John M. de Castro, Ph.D.

“Musculoskeletal disorders (MSDs) is the term given to a variety of painful conditions that affect the muscles, bones, and joints, which are a leading cause of long term sickness absence. . .MSDs are also at risk of developing symptoms of depression . . . Being off work for a significant period of time, whether due to an musculoskeletal disorder or other condition, can cause many other repercussions – including mental health issues.” – Fit for Work

Orthopedic Disorders consist of a wide range of problems that are concerned with muscles, ligaments and joints. Disorders are ailments, injuries or diseases that cause knee problems, whiplash, dislocated shoulder, torn cartilages, foot pain and fibromyalgia. The most common forms of orthopedic disorders are arthritis, and back and neck pain.

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. The pain, stiffness, and lack of mobility associate with arthritis produce fatigue and markedly reduce the quality of life of the sufferers.

The most common forms of chronic pain are back and neck pain. Low Back Pain is the leading cause of disability worldwide and affects between 6% to 15% of the population. Back and neck pain interferes with daily living and with work, decreasing productivity and creating absences. Arthritis and back pain can have very negative psychological effects and may lead to depression, isolation, and withdrawal from friends and social activities.

There are many different treatments for pain, but few are both safe and effective for chronic musculoskeletal pain conditions. So, alternative treatments are needed. Mindfulness practices are effective in treating pain and have been shown to be safe and effective in the management of arthritis, low back pain and neck pain. In addition, mindfulness practices have been shown to improve mental health. So, it is likely that mindfulness practices will be effective for both the physical and mental health issues that accompany musculoskeletal disorders.

In today’s Research News article “Scoping review of systematic reviews of complementary medicine for musculoskeletal and mental health conditions.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6196876/ ), Lorenc and colleagues review and summarize the published research studies on the effectiveness of mindfulness practices for the treatment of the psychological problems that accompany musculoskeletal disorders.

They summarize the evidence from 111 published research studies and report that these studies support the effectiveness of yoga for low back pain, and anxiety; Tai Chi for osteoarthritis, depression, anxiety, and sleep disorders; meditation for depression, anxiety, and sleep disorders; and mindfulness for stress and distress. There were no safety problems found with any of these mindfulness techniques.

This review indicates that there has accumulated a large body of evidence for the safety and effectiveness of mindfulness practices for the physical and mental health issues that accompany musculoskeletal disorders. Hence the published research to date supports the use of mindfulness practices in the package of treatments for musculoskeletal disorders.

So, improve physical and mental health with musculoskeletal disorders with mindfulness practices.

“Yoga has been used to alleviate musculoskeletal pain and has been associated with significant improvement in range of motion and function, decreased tenderness, lower levels of depressive symptoms, and decreased pain during activity in patients with musculoskeletal disorders.” – Ruth McCaffrey

Study Summary

Lorenc, A., Feder, G., MacPherson, H., Little, P., Mercer, S. W., & Sharp, D. (2018). Scoping review of systematic reviews of complementary medicine for musculoskeletal and mental health conditions. BMJ open, 8(10), e020222. doi:10.1136/bmjopen-2017-020222

Abstract

Objective

To identify potentially effective complementary approaches for musculoskeletal (MSK)–mental health (MH) comorbidity, by synthesising evidence on effectiveness, cost-effectiveness and safety from systematic reviews (SRs).

Design

Scoping review of SRs.

Methods

We searched literature databases, registries and reference lists, and contacted key authors and professional organisations to identify SRs of randomised controlled trials for complementary medicine for MSK or MH. Inclusion criteria were: published after 2004, studying adults, in English and scoring >50% on Assessing the Methodological Quality of Systematic Reviews (AMSTAR); quality appraisal checklist). SRs were synthesised to identify research priorities, based on moderate/good quality evidence, sample size and indication of cost-effectiveness and safety.

Results

We included 84 MSK SRs and 27 MH SRs. Only one focused on MSK–MH comorbidity. Meditative approaches and yoga may improve MH outcomes in MSK populations. Yoga and tai chi had moderate/good evidence for MSK and MH conditions. SRs reported moderate/good quality evidence (any comparator) in a moderate/large population for: low back pain (LBP) (yoga, acupuncture, spinal manipulation/mobilisation, osteopathy), osteoarthritis (OA) (acupuncture, tai chi), neck pain (acupuncture, manipulation/manual therapy), myofascial trigger point pain (acupuncture), depression (mindfulness-based stress reduction (MBSR), meditation, tai chi, relaxation), anxiety (meditation/MBSR, moving meditation, yoga), sleep disorders (meditative/mind–body movement) and stress/distress (mindfulness). The majority of these complementary approaches had some evidence of safety—only three had evidence of harm. There was some evidence of cost-effectiveness for spinal manipulation/mobilisation and acupuncture for LBP, and manual therapy/manipulation for neck pain, but few SRs reviewed cost-effectiveness and many found no data.

Conclusions

Only one SR studied MSK–MH comorbidity. Research priorities for complementary medicine for both MSK and MH (LBP, OA, depression, anxiety and sleep problems) are yoga, mindfulness and tai chi. Despite the large number of SRs and the prevalence of comorbidity, more high-quality, large randomised controlled trials in comorbid populations are needed.

Restrain Body Fatness Growth During Adolescence with Yoga

Restrain Body Fatness Growth During Adolescence with Yoga

By John M. de Castro, Ph.D.

“Practicing yoga changes your mind: It changes the way you approach life, your body, and eating. Yoga shows you how to appreciate your body for all of the amazing things that it can do for you and points you in the direction of wanting to fill your body with the best possible fuel rather than processed junk food. And changing your mind about your body and the foods you feed it will be a much more effective weight-loss tool than burning a bunch of calories in an aggressive kick-boxing class and then mindlessly plowing through equal or more calories later that day.” – Heidi Kristoffer

Obesity has become an epidemic in the industrialized world. In the U.S. the incidence of obesity, has more than doubled over the last 35 years to currently around 35% of the population, while two thirds of the population are considered overweight or obese (Body Mass Index; BMI > 25). Obesity has been found to shorten life expectancy by eight years and extreme obesity by 14 years. This occurs because obesity is associated with cardiovascular problems such as coronary heart disease and hypertension, stroke, metabolic syndrome, diabetes, cancer, arthritis, and others.

Obviously, there is a need for effective treatments to prevent or treat overweight and obesity. But, despite copious research and a myriad of dietary and exercise programs, there still is no safe and effective treatment. It would be important to intervene early during growth to restrain the growth of body fatness. Mindfulness is known to be associated with lower risk for obesity, alter eating behavior and improve health in obesity. Yoga practice has been shown to have a myriad of physical and psychological benefits. These include significant loss in weight and body mass index (BMI), resting metabolism, and body fat in obese women with Type 2 diabetes and improves health in the obese. In addition, it has the added benefit of being a gentle exercise. Hence it would seem reasonable to further investigate the benefits of yoga practice on the weight and body composition during adolescence.

In today’s Research News article “How Is the Practice of Yoga Related to Weight Status? Population-Based Findings From Project EAT-IV.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5865393/ ), Neumark-Sztainer and colleagues utilized a longitudinal data set from Project EAT of adolescent Middle and High School students. They were measured for yoga practice, body size and demographic characteristics initially and after 5 years.

They found that 56.4% of females and 29.1% of males did some yoga while 20.5% of females and 6.1% of males practiced regularly in the past year. The frequency of yoga practice did not differ over weight status, but overweight adolescents were more likely to keep the yoga practice at a gentle level and less likely to engage in hot yoga or engage in a yoga class. Importantly, over the 5-year period the adolescents who practiced yoga had non-significant reductions in Body Mass Index (BMI), an index of body fatness while those that did not practice yoga had a significant increase in BMI. The adolescents who practiced yoga had significantly less body fatness gain over the 5-year period.

This study is important as it is a rare longitudinal look at body mass changes in adolescents over a 5-year period. But these results are correlational, so causation cannot be concluded. Nevertheless, the results are suggestive that adolescents benefit from yoga practice. They suggest that prolonged yoga practice works to restrain gain in body fatness during maturation. This could be very important during adolescence when body size is so important for the developing self-image and for social and romantic relationships, and is very important for their health and well-being later in life.

So, restrain body fatness growth during adolescence with yoga.

“Today urban society is stigmatized with chronic diseases. Unhealthy lifestyle is the main reason for the occurrence of chronic illness. BMI, is a reliable indicator of physical well-being of an individual, as there is urgent attention in the alarming rise of such diseases. Yoga works wonderful in stabilizing BMI and in restoring health.” – Minakshi Welukar

Abstract

Background

Yoga may provide a strategy for healthy weight management in young adults. This study examined prevalence and characteristics of young adults’ yoga practice and associations with changes in body mass index (BMI).

Methods

Surveys were completed by 1830 young adults (31.1±1.6 years) participating in Project EAT-IV. Cross-sectional and five-year longitudinal analyses were conducted stratified by initial weight status.

Results

Two-thirds (66.5%) of non-overweight women and 48.9% of overweight women reported ever doing yoga, while 27.2% of non-overweight women and 16.4% of overweight women practiced regularly (≥30 minutes/week). Fewer men practiced yoga. Among young adults practicing regularly (n=294), differences were identified in intensity, type, and location of yoga practice across weight status. Young adults who were overweight and practiced yoga regularly showed a non-significant five-year decrease in their BMI (−0.60 kg/m2; p=0.49), while those not practicing regularly had significant increases in their BMI (+1.37 kg/m2; p<0.01). Frequency of yoga was inversely associated with weight gain among both overweight and non-overweight young adults practicing yoga regularly.

Conclusions

Young adults of different body sizes practice yoga. Yoga was associated with less weight gain over time, particularly in overweight young adults. Practicing yoga on a regular basis may help with weight gain prevention.
