Improve Nervous System and Cognitive Function with Tai Chi

 

By John M. de Castro, Ph.D.

 

“tai chi appears to improve executive function—the ability to multitask, manage time, and make decisions—in people without any cognitive decline. In those with mild cognitive impairment, tai chi slowed the progression to dementia.” – Harvard Health

 

Tai Chi is an ancient Chinese practice involving mindfulness and gentle movements. It is easy to learn, safe, and gentle. 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 controlled breathing, mindful concentration, and gentle movements. Only recently though have the effects of this practice been scrutinized with empirical research. This research has found that it is effective for an array of physical and psychological issues. It appears to strengthen the immune system, reduce inflammation and increase the number of cancer killing cells in the bloodstream, improve cardiovascular health, reduce arthritis pain, improve balance and reduce falls. It also appears to improve attentional ability improve cognitive ability in the elderly, and relieve depression.

 

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 areas. In other words, mindfulness practice appears to mold and change the brain, producing psychological, physical, and spiritual benefits. Hence, it would appear likely that Tai Chi practice may alter the brain networks underlying mindfulness.

 

In today’s Research News article “Tai Chi Chuan Alters Brain Functional Network Plasticity and Promotes Cognitive Flexibility.” (See summary below or view the full text of the study at: https://www.frontiersin.org/articles/10.3389/fpsyg.2021.665419/full?utm_source=F-AAE&utm_medium=EMLF&utm_campaign=MRK_1671974_a0P58000000G0YfEAK_Psycho_20210701_arts_A ) Cui and colleagues recruited healthy adults and randomly assigned them to either a control condition or to 3, 60 minute sessions per week for 8 weeks of aerobic exercise (Brisk walking) or Tai Chi practice. Before and after practice they were measured for cognitive flexibility and they also had their brains scanned with functional Magnetic Resonance Imaging (fMRI).

 

They found that only after Tai Chi practice there was a significant increase in cognitive flexibility. The fMRI revealed that Tai Chi practice increased brain local efficiency compared with general aerobic exercise. Local efficiency reflects brain information transmission and processing in local densely interconnected areas. Tai Chi practice also increased the clustering coefficient of brain activity which reflects how well brain areas connect with other areas. Tai Chi practice increased Nodal global efficiency which reflects the efficiency of information transmission within brain networks. Importantly, they found that the higher the Nodal global efficiency the greater the level of cognitive flexibility. These changes with Tai Chi practice suggest that it increases brain specialization and that this is related to better cognitive ability.

 

A strength of the present study was that Tai Chi practice was compared to another aerobic exercise, brisk walking. So, it can be concluded that the effects observed were due to Tai Chi practice per se and not to the exercise provided by Tai Chi. The findings suggest then that practicing Tai Chi changes the brain making it better interconnected with a greater ability to share information and these changes are associated with greater cognitive flexibility. This shows that Tai Chi practice changes the brain in beneficial ways. This may be responsible for the ability of Tai Chi practice to improve the physical and psychological processes especially in the elderly.

 

So, improve nervous system and cognitive function with Tai Chi.

 

“Tai Chi, a multicomponent mind-body exercise, combines slow physical activity with relaxation to serve as a movement meditation. Prior trials suggested that the beneficial effects of Tai Chi are created by a physical component which capitalizes on the benefits of physical exercise and a mind component which additionally promotes psychological well-being, life satisfaction, and improved perception of health.” – Chunlin Yue

Study Summary

 

Cui L, Tao S, Yin H-c, Shen Q-q, Wang Y, Zhu L-n and Li X-j (2021) Tai Chi Chuan Alters Brain Functional Network Plasticity and Promotes Cognitive Flexibility. Front. Psychol. 12:665419. doi: 10.3389/fpsyg.2021.665419

 

Objective: This study used resting-state functional magnetic resonance imaging to investigate the effects of 8 weeks of Tai Chi Chuan and general aerobic exercise on the topological parameters of brain functional networks, explored the advantages of Tai Chi Chuan for improving functional network plasticity and cognitive flexibility, and examined how changes in topological attributes of brain functional networks relate to cognitive flexibility.

Methods: Thirty-six healthy adults were grouped into Tai Chi Chuan (Bafa Wubu of Tai Chi), general aerobic exercise (brisk walking), and control groups. All of the subjects underwent fMRI and behavioral assessment before and after the exercise intervention.

Results: Tai Chi Chuan exercise significantly enhanced the clustering coefficient and local efficiency compared with general aerobic exercise. Regarding the nodal properties, Tai Chi Chuan significantly enhanced the nodal clustering coefficient of the bilateral olfactory cortex and left thalamus, significantly reduced the nodal clustering coefficient of the left inferior temporal gyrus, significantly improved the nodal efficiency of the right precuneus and bilateral posterior cingulate gyrus, and significantly improved the nodal local efficiency of the left thalamus and right olfactory cortex. Furthermore, the behavioral performance results demonstrated that cognitive flexibility was enhanced by Tai Chi Chuan. The change in the nodal clustering coefficient in the left thalamus induced by Tai Chi Chuan was a significant predictor of cognitive flexibility.

Conclusion: These findings demonstrated that Tai Chi Chuan could promote brain functional specialization. Brain functional specialization enhanced by Tai Chi Chuan exercise was a predictor of greater cognitive flexibility.

Improve the Mental, Physical, and Emotional Well-Being of Older Adults During Covid-19 Pandemic with Tai Chi

 

By John M. de Castro, Ph.D.

 

“Tai Chi Chuan has a potential effect on the prevention, treatment and rehabilitation of COVID-19. Its potential mechanisms include reducing anxiety, relieving depression and stress, enhancing pulmonary and cardiovascular function, enhancing immunity and improving quality of life.” – Chen Xianjian

 

The COVID-19 pandemic has challenged the mental and physical health of the population. It has created intense stress on everyone but particularly the elderly isolating at home. Mindfulness is known to decrease the psychological and physical responses to stress. So, mindfulness training may be helpful in coping with the mental and physical challenges resulting from the COVID-19 pandemic. Tai Chi and Qigong are both mindfulness practices and gentle exercises. They have been shown to be beneficial for the health and well-being of individuals of a variety of ages, but particularly the elderly. So, it would seem reasonable to examine the ability of Tai Chi practice to improve the well-being of older adults during the Covid-19 pandemic.

 

In today’s Research News article “Tai chi improves psychoemotional state, cognition, and motor learning in older adults during the COVID-19 pandemic.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8054611/ ) Solianik and colleagues recruited healthy sedentary older adults (over 60 years of age) during the Covid-19 pandemic and randomly assigned them to 10 weeks of twice a week for 60 minute Tai Chi practice or to a no treatment control condition. They were measured before and after training for heart rate, perceived stress, anxiety, depression cognitive performance, and motor performance. In addition, blood was drawn and assayed for brain-derived neurotrophic factor.

 

They found that in comparison to baseline and the control group, the older adults who practiced Tai Chi had significantly higher levels of brain-derived neurotrophic factor, high frequency power in the heart rate, visuospatial performance, response inhibition, and shifting mental set, and significantly lower reaction times, heart rate, perceived stress, and depression.

 

The results must be interpreted with the understanding that the control condition was no treatment in a sedentary group of older adults. So, it cannot be determined if the effects were due to Tai Chi itself or exercise in general. Nevertheless, Tai Chi practice resulted in significant improvements in cardiovascular fitness, brain development, cognitive performance, and psychological health.

 

Tai Chi practice is not strenuous, involves slow gentle movements, and is safe, having no appreciable side effects, it is appropriate the elderly. It can also be practiced without professional supervision and in groups making it inexpensive to deliver and fun to engage in. This suggests that during stressful times Tai Chi should be recommended for older adults for their mental, physical, and emotional well-being.

 

So, improve the mental, physical, and emotional well-being of older adults during Covid-19 pandemic with Tai Chi.

 

“Older people should exercise for the entire duration of self-isolation. One large systematic review of falls prevention exercises emphasised the importance of maintaining exercise over time – benefits from Tai Chi were found after 20 weeks.” –  Jamie Hartmann-Boyce

Study Summary

 

Solianik, R., Mickevičienė, D., Žlibinaitė, L., & Čekanauskaitė, A. (2021). Tai chi improves psychoemotional state, cognition, and motor learning in older adults during the COVID-19 pandemic. Experimental gerontology, 150, 111363. https://doi.org/10.1016/j.exger.2021.111363

 

Abstract

The aim of this study was to determine the effect of a 10-week tai chi intervention on psychoemotional state, cognition, and motor learning in older adults during the COVID-19 pandemic. Participants aged 60–78 years were randomized to either a control group (n = 15) or a tai chi group (n = 15) for a 10-week period. The tai chi group received two, 8-form tai chi classes of 60 min duration per week. Changes in psychoemotional state, cognition, and the learning of fast and accurate reaching movements were assessed. In addition, the potential roles of the autonomic nervous system and brain-derived neurotrophic factor (BDNF) were investigated. Tai chi practice decreased (P < 0.05) perceived stress, whereas no change in autonomic nervous system activity was observed. Improvements in mental switching correlated with decreased depressive symptoms and increased BDNF levels (P < 0.05), whereas improvements in inhibitory control tended to correlate with BDNF levels (P = 0.08). Improvements in visuospatial processing tended to correlate with decreased depressive symptoms (P = 0.07) while improved visuospatial processing correlated with improved motor planning during learning tasks (P < 0.05). This study suggests that tai chi is an effective intervention that can be delivered under pandemic conditions to improve mental and physical function in older adults.

Forest Walking and Forest Qigong Improve Cognitive Function in the Elderly

 

By John M. de Castro, Ph.D.

 

“forest bathing has received increasing attention due to its health-promoting effects, including enhancing immune functions and decreasing blood pressure in hypertension patients, as well as stress relief effects.” – Genxiang Mao,

 

Modern living is stressful, perhaps, in part because it has divorced us from the natural world that our species was immersed in throughout its evolutionary history. Modern environments may be damaging to our health and well-being simply because the species did not evolve to cope with them. This suggests that returning to nature, at least occasionally, may be beneficial. Indeed, researchers are beginning to study nature walks or what the Japanese call “Forest Bathing” and their effects on our mental and physical health.

 

Mindfulness practices have been found routinely to reduce the psychological and physiological responses to stress and improve mood. People have long reported that walking in nature elevates their mood. It appears intuitively obvious that if mindfulness training occurred in a beautiful natural place, it would greatly improve the effectiveness of mindfulness practice. In fact, being in nature has been shown to improve psychological health.

 

Qigong has been practiced for thousands of years with benefits for health and longevity. Qigong training is designed to enhance function and regulate the activities of the body through regulated breathing, mindful concentration, and gentle movements. Qigong  practice has been found to be effective for an array of physical and psychological issues. Qigong has been shown to help the elderly improve attention, balance, reducing falls, arthritis, cognitive function, memory, and reduce age related deterioration of the brain. So, it makes sense to further study the ability of Qigong training particularly when practiced in nature to improve well-being in the elderly.

 

In today’s Research News article “Psycho-Electrophysiological Benefits of Forest Therapies Focused on Qigong and Walking with Elderly Individuals.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7999348/ ) Yi and colleagues recruited healthy elderly (65 years of age and older) participants and assigned them to one of 3 conditions; no-treatment control, forest walking, or forest Qigong. The forest programs were 2 hours per session twice per week for 6 weeks and included warm-up exercises, stretching, physio-cognitive play, and cool-down along with 50 minutes of either forest walking, or forest Qigong. They were measured before and after training for cognitive impairment, depression, and quality of life. They also had the electroencephalogram (EEG) and electrocardiogram (EKG) recorded. Bioimpedance was used to determine body composition and nutritional metabolism.

 

They found that in comparison to baseline and the no-treatment control condition, the forest qigong group had a significant decrease in depression while the forest walking group had a significant decrease in cognitive impairment and increase in quality of life. In the EEG, the forest walking group had significant increases in Alpha and Beta rhythm power and a significant decrease in low frequency heart rate variability after training while the control and forest qigong groups did not. In addition, the forest qigong group had a significant increase in the upper body bioimpedance phase angle while the forest walking group had a significant increase in the lower body bioimpedance phase angle.

 

Bioimpedance phase angle is an indicator of the metabolic nutrition of the muscles. So, the practice of qigong in the forest appears to increase the metabolic nutritional status of the upper body while walking in the forest appears to increase the metabolic nutritional status of the lower body. This is not surprising as qigong involves frequent arm movements while walking involves more leg movements. Low frequency heart rate variability is an indicator of sympathetic nervous system activity and its decrease in the forest walking group suggests that walking in the forest is physiologically relaxing, reducing activating sympathetic activity. Finally, EEG power is indicative of brain information processing and its increase with forest walking is indicative of an increase in information (cognitive) processing.

 

These findings are interesting and suggest that walking in the forest and qigong in the forest have different effects on elderly individuals. Where forest qigong appears to be superior for decreasing depression and upper body metabolism, forest walking appears to improve cognitive ability, lower body metabolism, and physiological relaxation. Hence qigong in the forest is superior for emotional health while walking in the forest is superior for cognitive health. This suggests that the combination of qigong and walking in the forest may produce better well-being for elderly individual.

 

So, forest walking and forest qigong improve cognitive function in the elderly.

Abstract

We developed two distinct forest therapy programs (FTPs) and compared their effects on dementia prevention and related health problems for older adults. One was focused on Qigong practice in the forest (QP) and the other involved active walking in the forest (WP). Both FTPs consisted of twelve 2-h sessions over six weeks and were conducted in an urban forest. We obtained data from 25, 18, and 26 participants aged 65 years or above for the QP, WP, and control groups, respectively. Neuropsychological scores via cognition (MoCA), geriatric depression (GDS) and quality of life (EQ-5D), and electrophysiological variables (electroencephalography, bioimpedance, and heart rate variability) were measured. We analyzed the intervention effects with a generalized linear model. Compared to the control group, the WP group showed benefits in terms of neurocognition (increases in the MoCA score, and alpha and beta band power values in the electroencephalogram), sympathetic nervous activity, and bioimpedance in the lower body. On the other hand, the QP group showed alleviated depression and an increased bioimpedance phase angle in the upper body. In conclusion, both active walking and Qigong in the forest were shown to have distinctive neuropsychological and electrophysiological benefits, and both had beneficial effects in terms of preventing dementia and relieving related health problems for elderly individuals.

Improve Hypertension and Hyperlipidemia in Older Adults with Tai Chi

Improve Hypertension and Hyperlipidemia in Older Adults with Tai Chi

 

By John M. de Castro, Ph.D.

 

“Tai Chi is not only a suitable exercise for elderly people with obesity, but it can also help to regulate BP, improve heart and lung function in these individuals, as well as reduce the incidence of cardiovascular disease and other chronic diseases, helping to improve their quality of life.” – Sun Lei

 

High Blood Pressure (Hypertension) is an insidious disease because there are no overt symptoms. The individual feels fine. But it can be deadly as more than 360,000 American deaths, roughly 1,000 deaths each day, had high blood pressure as a primary or contributing cause. In addition, hypertension markedly increases the risk heart attack, stroke, heart failure, and kidney disease.  It is also a very common disorder with about 70 million American adults (29%) having high blood pressure and only about half (52%) of people with high blood pressure have their condition under control. Treatment frequently includes antihypertensive drugs. But these medications often have adverse side effects. So, patients feel lousy when taking the drugs, but fine when they’re not. So, compliance is a major issue with many patients not taking the drugs regularly or stopping entirely.

 

Obviously, there is a need for alternative to drug treatments for hypertension. Mindfulness practices have been shown to aid in controlling hypertension. Mindful movement practices such Tai Chi and Qigong are ancient Chinese practices involving mindfulness and gentle movements. They are easy to learn, safe, and gentle. So, it may be appropriate for patients with hypertension who lack the ability to engage in strenuous exercises. Indeed, Tai Chi practice has been shown to reduce blood pressure.

 

In today’s Research News article “A Randomized Trial of Tai Chi on Preventing Hypertension and Hyperlipidemia in Middle-Aged and Elderly Patients.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8160700/ ) Wen and colleagues recruited patients with hypertension and hyperlipidemia between the ages of 40-75 years. They were randomly assigned to practice for 6 weeks, 3 time per week, for 60 minutes either simplified Tai Chi (24 form Yang style) or a Wu Style Tai Chi (60 forms) that was designed for hypertension and hyperlipidemia. They also practiced at home for 30 minutes a day. They were measured before and after the interventions for body size, blood pressure, blood glucose, and blood lipids.

 

They found that the patients who practiced Wu Style Tai Chi in comparison to the simplified Tai Chi had significantly greater reductions in both systolic and diastolic blood pressure, triglycerides, and LDL Cholesterol and greater increases in HDL Cholesterol in comparison to baseline. In addition, a greater percentage of patients who practiced Wu Style Tai Chi discontinued antihypertensive drugs and showed clinically significant reductions in cardiovascular disease.

 

In the present study both forms of Tai Chi produced improvements in hypertension and hyperlipidemia as has been observed in previous research. But the present study demonstrated that Wu Style Tai Chi produces superior results. Wu Style is more complex and also emphasizes reverse abdominal breathing matched to the movements. It is believed that this increases circulation and may be responsible for the greater improvements. Regardless, Tai Chi is a safe and effective treatment for hypertension and hyperlipidemia in older adults.

 

So, improve hypertension and hyperlipidemia in older adults with Tai Chi.

Abstract

In our randomized controlled trial, we investigated whether Wu-style Tai Chi (Tai Chi combined with Daoyin) as a potential exercise prescription is more effective than simplified Tai Chi in the prevention and treatment of hypertension and hyperlipidemia in the middle-aged and elderly. We randomly assigned 66 patients with hypertension and hyperlipidemia to one of the two groups: the Wu-style Tai Chi group or the simplified Tai Chi group; the simplified Tai Chi group only exercised simplified Tai Chi three times a week for 6 weeks. The Wu-style Tai Chi group participated in 60 min of Wu-style Tai Chi three times a week for 6 weeks. Serum biochemical tests were conducted at baseline and at the end of the study. Measurements of blood pressure were performed at the same time. Primary outcomes were compared within and between groups at baseline and at 6 weeks. The participants in the Wu-style Tai Chi group performed, at 6 weeks, significantly better than baseline on all of the primary outcomes (p value ≤ 0.05). The results also show significant difference within the simplified Tai Chi group from baseline to 6 weeks in TCHO (mmol/L), SBP (mmHg), and LDL-C (mmol/L) (p value < 0.05). From baseline to 6 weeks, the Wu-style Tai Chi group had significant differences at more test indexes in serum and blood pressure than the simplified Tai Chi group. At 6 weeks, the Wu-style Tai Chi group had a significantly greater mean improvement in the SBP (mmHg) than did the simplified Tai Chi group (mean between-group difference, −5.80 (mmHg) [95% CI, −14.01 to 2.41]; p = 0.007). The results showed that, compared with simplified Tai Chi, Wu-style Tai Chi had a better effect on hypertension in the middle-aged and elderly. At 6 weeks in LDL-C (mmol/L), the Wu-style Tai Chi group had significantly greater improvement between the two groups (means between-group difference, −0.45 (mmol/L) [95% CI, −0.89 to −0.17]; p = 0.03). The results showed that Wu-style Tai Chi protected the cardiovascular system of the middle-aged and elderly in improving LDL-C (mmol/L), and was more significant than simplified Tai Chi. After 6 weeks of exercise, Wu-style Tai Chi could effectively improve hyperlipidemia and hypertension. The total effective rate of cardiovascular disease was 90.00%. There was significant difference in the treatment effect of hypertension and hyperlipidemia between the two groups during 6 weeks (p = 0.039), showing that, in a small population of middle-aged and elderly subjects, Wu style Tai Chi could be useful in managing important CV risk factors, such as hypertension and hyperlipidemia.

Improve Cognitive Ability in Older Adults with Tai Chi and Qigong Practices

 

By John M. de Castro, Ph.D.

 

“Qigong exercise induced significant neurocognitive improvement in aging.” – Di Qi

 

The aging process involves a systematic progressive decline in every system in the body, the brain included. The elderly frequently have problems with attention, thinking, and memory abilities, known as mild cognitive impairment. An encouraging new development is that mindfulness practices such as meditation training and mindful movement practices can significantly reduce these declines in cognitive ability.

 

Tai Chi and Qigong have been practiced for thousands of years with benefits for health and longevity. Tai Chi and Qigong trainings are designed to enhance function and regulate the activities of the body through regulated breathing, mindful concentration, and gentle movements. Tai Chi and Qigong practice have been found to be effective for an array of physical and psychological issues. Tai Chi and Qigong have been shown to help the elderly improve attention, balance, reducing falls, arthritis, cognitive function, memory, and reduce age related deterioration of the brain. The research findings have been accumulating suggesting that a summarization of what has been learned about the effects of Tai Chi and Qigong practice on the cognitive ability of older adults is called for.

 

In today’s Research News article “Effects of Chinese Mind-Body Exercises on Executive Function in Middle-Aged and Older Adults: A Systematic Review and Meta-Analysis.” (See summary below or view the full text of the study at: https://www.frontiersin.org/articles/10.3389/fpsyg.2021.656141/full?utm_source=F-AAE&utm_medium=EMLF&utm_campaign=MRK_1645362_69_Psycho_20210525_arts_A ) Ren and colleagues review, summarize, and perform a meta-analysis of the published research on the effects of Tai Chi and Qigong practice on the cognitive ability of older adults. They identified 29 published randomized controlled trials employing participants over 50 years of age.

 

They report that the published research found that Tai Chi and Qigong practice produced significant increases in overall executive function including improvements in short-term memory and shifting, the ability to shift from attentional focus to attentional focus. They also found that when practice occurred 5 or more times per week, the effects doubled compared to practice less than 4 times per week.

 

The findings suggest that Tai Chi and Qigong practices are effective in improving thinking in older adults. Since cognitive abilities tend to decline with age, the results suggests that Tai Chi and Qigong practice may protect against age related cognitive decline. This is true especially when practice occurs 5 or more times per week.

 

Some advantages of Tai Chi and Qigong include the facts that they are not strenuous, involve slow gentle movements, are safe, having no appreciable side effects, and are appropriate for all ages including the elderly and for individuals with illnesses that limit their activities or range of motion. It can also be practiced without professional supervision and in groups making it inexpensive to deliver and fun to engage in. This makes Tai Chi and Qigong practice excellent practices for protecting older individuals from age related cognitive decline.

 

So, improve cognitive ability in older adults with Tai Chi and Qigong practices.

 

“Tai chi appears to improve executive function—the ability to multitask, manage time, and make decisions—in people without any cognitive decline. In those with mild cognitive impairment, tai chi slowed the progression to dementia more than other types of exercise and improved their cognitive function in a comparable fashion to other types of exercise or cognitive training.” – Havard Health

Study Summary

 

Ren F-F, Chen F-T, Zhou W-S, Cho Y-M, Ho T-J, Hung T-M and Chang Y-K (2021) Effects of Chinese Mind-Body Exercises on Executive Function in Middle-Aged and Older Adults: A Systematic Review and Meta-Analysis. Front. Psychol. 12:656141. doi: 10.3389/fpsyg.2021.656141

 

Chinese mind-body exercises (CMBEs) are positively associated with executive function (EF), but their effects on EF, from synthesized evidence using systematic and meta-analytic reviews, have not been conducted. Therefore, the present systematic review with meta-analysis attempted to determine whether CMBEs affect EF and its sub-domains, as well as how exercise, sample, and study characteristics moderate the causal relationship between CMBEs and EF in middle-aged and older adults. Seven electronic databases were searched for relevant studies published from the inception of each database through June 2020 (PubMed, Web of Science, Embase, Cochrane Controlled Trials Register, Wanfang, China National Knowledge Infrastructure, and Weipu). Randomized controlled trials with at least one outcome measure of CMBEs on EF in adults of mean age ≥ 50 years with intact cognition or mild cognitive impairment (MCI) and with or without chronic diseases were included. A total of 29 studies (N = 2,934) ultimately were included in this study. The results indicated that CMBEs improved overall EF (Standardized Mean Differences = 0.28, 95% CI 0.12, 0.44), as well as its sub-domains of working memory and shifting. The beneficial effects of CMBEs on EF occurred regardless of type (Tai Chi, Qigong), frequency of group classes (≤2 time, 3-4 time, ≥5 times), session time (≤45 min, 46-60 min), total training time (≥150 to ≤300 min, >300 min), and length of the CMBEs (4-12 week, 13-26 week, and >26 week), in addition to that more frequent participation in both group classes and home practice sessions (≥5 times per week) resulted in more beneficial effects. The positive effects of CMBEs on EF were also demonstrated, regardless of participants mean age (50-65 years old, >65 years old), sex (only female, both), and cognitive statuses (normal, MCI, not mentioned), health status (with chronic disease, without chronic disease), as well as training mode (group class, group class plus home practice) and study language (English, Chinese). This review thus suggests that CMBEs can be used as an effective method with small to moderate and positive effects in enhancing EF, and that more frequent group classes and home practice sessions may increase these effects. However, certain limitations, including strictly design studies, limited ES (effect size) samples for specific variables, and possible biased publications, required paying particular attention to, for further exploring the effects of CMBEs on EF.

Improve the Respiratory Symptoms of Lung Cancer Patients with Qigong Practice

“Studies show that qigong practice can have many positive effects, particularly among patients with cancer, chronic illnesses, and breathing problems, as well as older adults. Benefits include improved lung function, mood, sleep, and quality of life, as well as reduced stress, pain, anxiety, and fatigue.” – Sloan Kettering Institute

 

Receiving a diagnosis of cancer has a huge impact on most people. Feelings of depression, anxiety, and fear are very common and are normal responses to this life-changing and potentially life-ending experience. But cancer diagnosis is not necessarily a death sentence. Over half of the people diagnosed with cancer are still alive 10 years later and this number is rapidly increasing. But, surviving cancer carries with it a number of problems. Anxiety, depression, fatigue and insomnia are common symptoms in the aftermath of surviving cancer. These symptoms markedly reduce the quality of life of the patients.

 

Mindfulness training has been shown to help with cancer recovery and help to alleviate many of the residual physical and psychological symptoms, including stress,  sleep disturbance, and anxiety and depression. Tai Chi or Qigong practice has been shown to improve quality of life, reduce fatigue, and lower blood pressure and cortisol levels. They are very gentle and safe practices. The research on the effectiveness of Qigong training for lung cancer patients is sparse. So, it makes sense to Investigate the ability of Qigong training to improve the symptoms of lung cancer.

 

In today’s Research News article “The Effectiveness of Qigong in Managing a Cluster of Symptoms (Breathlessness-Fatigue-Anxiety) in Patients with Lung Cancer: A Randomized Controlled Trial.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8047940/ )  Molassiotis and colleagues recruited patients who had complete treatment for lung cancer and randomly assigned them to either a wait-list control group or to engage in Qigong practice. They were trained in Qigong in 2 weekly 90-minute practices for 2 weeks and then practiced Qigong at home for 30 minutes per day, 5 days per week, for 4 weeks. They were measured before and after training and at 12 weeks for disease status, fatigue, dyspnea (difficulty with breathing), anxiety, depression, cough frequency intensity and bothersomeness, and quality of life.

 

They found that in comparison to baseline the group that practiced Qigong had significant reductions in fatigue, dyspnea (difficulty with breathing), anxiety, and cough score that were maintained at the 12-week follow-up. These effects were significantly greater in men than in women. Hence, Qigong practice appeared to improve the symptoms in lung cancer patients.

 

It should be noted that 2 weeks of Qigong training followed by 4 weeks of home practice is a rather low amount of practice relative to what is usually prescribed in other controlled research, as much as 6 months of practice. In addition, only 62% of the Qigong group completed the practice with a 62% adherence rate. So, the effective dose of Qigong was low. This suggests that if practice was extended over longer periods of time greater effectiveness would have been observed. Nevertheless, Qigong practice, even in low dose, had positive benefits for lung cancer patients.

 

So, improve the respiratory symptoms of lung cancer patients with Qigong practice.

The Effectiveness of Qigong in Managing a Cluster of Symptoms (Breathlessness-Fatigue-Anxiety) in Patients with Lung Cancer: A Randomized Controlled Trial. Integrative cancer therapies, 20, 15347354211008253. https://doi.org/10.1177/15347354211008253

 

Abstract

Background and Purpose:

Qigong is used by cancer patients, but its effect is not adequately evaluated to date. The aim of this study was to investigate the effects of Qigong for the management of a symptom cluster comprising fatigue, dyspnea, and anxiety in patients with lung cancer.

Methodology:

A total of 156 lung cancer patients participated in this trial, and they were randomized to a Qigong group (6 weeks of intervention) or a waitlist control group receiving usual care. The symptom cluster was assessed at baseline, at the end of treatment (primary outcome), and at 12 weeks, alongside measures of cough and quality of life (QOL).

Results:

There was no significant interaction effect between group and time for the symptom cluster overall and for fatigue and anxiety. However, a significant trend towards improvement was observed on fatigue (P = .004), dyspnea (P = .002), and anxiety (P = .049) in the Qigong group from baseline assessment to the end of intervention at the 6th week (within-group changes). Improvements in dyspnea and in the secondary outcomes of cough, global health status, functional well-being and QOL symptom scales were statistically significant between the 2 groups (P = .001, .014, .021, .001, and .002, respectively).

Conclusion:

Qigong did not alleviate the symptom cluster experience. Nevertheless, this intervention was effective in reducing dyspnea and cough, and improving QOL. More than 6 weeks were needed, however, for detecting the effect of Qigong on improving dyspnea. Furthermore, men benefited more than women. It may not be beneficial to use Qigong to manage the symptom cluster consisting of fatigue, dyspnea, and anxiety, but it may be effective in managing respiratory symptoms (secondary outcomes needing further verification in future research). Future studies targeting symptom clusters should ensure the appropriateness of the combination of symptoms.

Improve Hypertension with Tai Chi

 

By John M. de Castro, Ph.D.

 

“under well-designed conditions, Tai Chi exercise training could decrease blood pressure and results in favorable lipid profile changes and improve subjects’ anxiety status. Therefore, Tai Chi could be used as an alternative modality in treating patients with mild hypertension, with a promising economic effect.” – Jen-Chen Tsai

 

High Blood Pressure (Hypertension) is an insidious disease because there are no overt symptoms. The individual feels fine. But it can be deadly as more than 360,000 American deaths, roughly 1,000 deaths each day, had high blood pressure as a primary or contributing cause. In addition, hypertension markedly increases the risk heart attack, stroke, heart failure, and kidney disease.  It is also a very common disorder with about 70 million American adults (29%) having high blood pressure and only about half (52%) of people with high blood pressure have their condition under control. Treatment frequently includes antihypertensive drugs. But these medications often have adverse side effects. So, patients feel lousy when taking the drugs, but fine when they’re not. So, compliance is a major issue with many patients not taking the drugs regularly or stopping entirely.

 

Obviously, there is a need for alternative to drug treatments for hypertension. Mindfulness practices have been shown to aid in controlling hypertension. Mindful movement practices such Tai Chi and Qigong are ancient Chinese practices involving mindfulness and gentle movements. They may be appropriate for patients with hypertension who lack the ability to engage in strenuous exercises. Indeed, Qigong practice has been shown to reduce blood pressure. There have been a number of studies performed and it is useful to summarize what has been learned.

 

In today’s Research News article “Tai Ji Quan as antihypertensive lifestyle therapy: 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/PMC7987647/ )  Wu and colleagues reviewed, summarized, and performed a meta-analysis of the published research studies on the effectiveness of Tai Chi practice for the treatment of hypertension in adults..

 

They found 15 published controlled research studies and report that these studies found that Tai Chi practice alone produced significant reductions in both systolic and diastolic blood pressure in patients with hypertension. These effects were greatest when the baseline blood pressure was highest. The size of the blood pressure reductions would be expected to reduce cardiovascular disease risk by at least 40%.

 

It is important to note that Tai Chi and Qigong are ancient mindfulness practices involving slow prescribed movements. They are gentle and completely safe, can be used with the elderly and sickly, are inexpensive to administer, can be performed in groups or alone, at home or in a facility or even public park, and can be quickly learned. In addition, they can also be practiced in social groups without professional supervision. This can make it fun, improving the likelihood of long-term engagement in the practice. Hence, Tai Chi practice is an almost ideal treatment for hypertension.

 

So, improve hypertension with Tai Chi.

 

“Despite its gentle nature, the health benefits of tai chi can be impressive.” – Abbott

Abstract

Background

Professional health organizations are not currently recommending Tai Ji Quan alongside aerobic exercise to treat hypertension. We aimed to examine the efficacy of Tai Ji Quan as antihypertensive lifestyle therapy.

Methods

Tai Ji Quan interventions published in English and Chinese were included when they involved healthy adults, reported pre- and post-intervention blood pressure (BP), and had a non-exercise/non-diet control group. We systematically searched 11 electronic databases for studies published through July 31, 2018, yielding 31 qualifying controlled trials. We (1) evaluated the risk of bias and methodological study quality, (2) performed meta-regression analyses following random-effects assumptions, and (3) generated additive models representing the largest possible clinically relevant BP reductions.

Results

Participants (n = 3223) were middle-aged (56.6 ± 15.1 years of age, mean ± SD) adults with prehypertension (systolic BP (SBP) = 136.9 ± 15.2 mmHg, diastolic BP (DBP) = 83.4 ± 8.7 mmHg). Tai Ji Quan was practiced 4.0 ± 1.4 sessions/week for 54.0 ± 10.6 min/session for 22.3 ± 20.2 weeks. Overall, Tai Ji Quan elicited significant reductions in SBP (–11.3 mmHg, 95%CI: –14.6 to –8.0; d+ = –0.75) and DBP (–4.8 mmHg, 95%CI: –6.4 to –3.1; d+ = –0.53) vs. control (p < 0.001). Controlling for publication bias among samples with hypertension, Tai Ji Quan trials published in English elicited SBP reductions of 10.4 mmHg and DBP reductions of 4.0 mmHg, which was half the magnitude of trials published in Chinese (SBP reductions of 18.6 mmHg and DBP reductions of 8.8 mmHg).

Conclusion

Our results indicate that Tai Ji Quan is a viable antihypertensive lifestyle therapy that produces clinically meaningful BP reductions (i.e., 10.4 mmHg and 4.0 mmHg of SBP and DBP reductions, respectively) among individuals with hypertension. Such magnitude of BP reductions can lower the incidence of cardiovascular disease by up to 40%.

Tai Chi Practice Improves the Symptoms of Multiple Diseases

Tai Chi Practice Improves the Symptoms of Multiple Diseases

 

By John M. de Castro, Ph.D.

 

“In addition to easing balance problems, and possibly other symptoms, tai chi can help ease stress and anxiety and strengthen all parts of the body, with few if any harmful side effects.” Peter Wayne

 

Tai Chi is an ancient mindfulness practice involving slow prescribed movements. It is gentle and completely safe, can be used with the elderly and sickly, is inexpensive to administer, can be performed in groups or alone, at home or in a facility or even public park, and can be quickly learned. In addition, it can also be practiced in social groups without professional supervision. This can make it fun, improving the likelihood of long-term engagement in the practice. Indeed, studies have shown that Tai Chi practice is effective in improving the symptoms of many different diseases. The evidence is accumulating. So, it makes sense to step back and summarize what has been learned about the effectiveness of different Tai Chi practices for different disease conditions.

 

In today’s Research News article “.Clinical Evidence of Tai Chi Exercise Prescriptions: A Systematic Review” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7972853/ ) Huang and colleagues review and summarize the published randomized controlled trials on the effectiveness of different Tai Chi practices for different disease conditions. They identified 139 published randomized controlled trials utilizing a number of different Tai Chi styles and numbers of forms. Yang style was by far the most frequent style and 24 forms was the most frequent number of forms employed.

 

They report that the published research found that Tai Chi practice produced significant improvement in the symptoms of musculoskeletal system or connective tissue diseases such as osteoarthritis, fibromyalgia, and chronic low back pain.; on circulatory system diseases such as hypertension, stroke, coronary heart disease, and chronic heart failure; on mental and behavioral disorders such as depression, cognitive impairment, and intellectual disabilities; on nervous system diseases such as Parkinson’s disease, dementia, and sleep disorders; on chronic obstructive pulmonary disease (COPD); on endocrine, nutritional, or metabolic diseases such as type 2 diabetes and metabolic syndrome; on the physical and mental state of cancer patients, and on traumatic brain injury and urinary tract disorders; on balance control and flexibility and falls in older adults.

 

These are remarkable findings. Tai Chi practice appears to be a safe and effective treatment for the symptoms of a wide variety of diseases. It doesn’t cure the disease. Rather if alleviates the symptoms. It is not known the mechanisms by which Tai Chi has these benefits. Future research needs to further explore what facets or effects of Tai Chi practice are responsible for the disease symptom improvements.

 

So, Tai Chi practice improves the symptoms of multiple diseases.

Abstract

Objectives

This systematic review aims to summarize the existing literature on Tai Chi randomized controlled trials (RCTs) and recommend Tai Chi exercise prescriptions for different diseases and populations.

Methods

A systematic search for Tai Chi RCTs was conducted in five electronic databases (PubMed, Cochrane Library, EMBASE, EBSCO, and Web of Science) from their inception to December 2019. SPSS 20.0 software and Microsoft Excel 2019 were used to analyze the data, and the risk of bias tool in the RevMan 5.3.5 software was used to evaluate the methodological quality of RCTs.

Results

A total of 139 articles were identified, including diseased populations (95, 68.3%) and healthy populations (44, 31.7%). The diseased populations included the following 10 disease types: musculoskeletal system or connective tissue diseases (34.7%), circulatory system diseases (23.2%), mental and behavioral disorders (12.6%), nervous system diseases (11.6%), respiratory system diseases (6.3%), endocrine, nutritional or metabolic diseases (5.3%), neoplasms (3.2%), injury, poisoning and certain other consequences of external causes (1.1%), genitourinary system diseases (1.1%), and diseases of the eye and adnexa (1.1%). Tai Chi exercise prescription was generally classified as moderate intensity. The most commonly applied Tai Chi style was Yang style (92, 66.2%), and the most frequently specified Tai Chi form was simplified 24-form Tai Chi (43, 30.9%). 12 weeks and 24 weeks, 2-3 times a week, and 60 min each time was the most commonly used cycle, frequency, and time of exercise in Tai Chi exercise prescriptions.

Conclusions

We recommend the more commonly used Tai Chi exercise prescriptions for different diseases and populations based on clinical evidence of Tai Chi. Further clinical research on Tai Chi should be combined with principles of exercise prescription to conduct large-sample epidemiological studies and long-term prospective follow-up studies to provide more substantive clinical evidence for Tai Chi exercise prescriptions.

Improve Balance and Exercise Capacity in Stroke Patients with Tai Chi

 

By John M. de Castro, Ph.D.

 

“With a complete focus on slow, controlled, and repetitive movements, tai chi is effective in improving one’s balance through dynamic motion and coordination, which is crucial to prevent falls. What many people may not know is that stroke survivors endure seven times as many falls each year as healthy adults.” – Henry Hoffman

 

Every year, more than 795,000 people in the United States have a stroke and it is the third leading cause of death, killing around 140,000 Americans each year. A stroke results from an interruption of the blood supply to the brain, depriving it of needed oxygen and nutrients. This can result in the death of brain cells and depending on the extent of the damage produce profound loss of function. Even after recovery from stroke patients can experience residual symptoms. Problems with balance and falling are very common. About 30% of stroke survivors develop spasticity, where the muscles become stiff, tighten up, and resist stretching. Obviously, spasticity can interfere with regaining movement after stroke.

 

The ancient mindful movement technique Tai Chi and Qigong are very safe forms of gentle exercise that appears to be beneficial for stroke victims including improving balance. Tai Chi involves both gentle exercise and mindfulness practice. Much has been learned. So, it makes sense to step back and summarize the research findings.

 

In today’s Research News article “The Influences of Tai Chi on Balance Function and Exercise Capacity among Stroke Patients: A Meta-Analysis.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7932789/ ) Zheng and colleagues review, summarize, and perform a meta-analysis of the published randomized controlled trials of the effectiveness of Tai Chi practice for the rehabilitation of stroke survivors. They identified 19 published randomized controlled trials.

 

They found that Tai Chi practice produced a significant improvement in balance. Standing and walking ability, 6-minute walking distance, gravity center swing, and exercise ability. Hence, the published randomized controlled trials make a strong case that Tai Chi practice is a safe and effective non-drug treatment to improve the balance and motor ability of stroke patients. These improvements should reduce the incidence of dangerous falls and improve the overall health and quality of life of these patients.

 

Tai Chi practice is not strenuous, involves slow gentle movements, and is safe, having no appreciable side effects, it is appropriate for all ages including the elderly and for individuals with illnesses that limit their activities or range of motion such as stroke. It can also be practiced without professional supervision and in groups making it inexpensive to deliver and fun to engage in. This makes Tai Chi practice an excellent means to help improve the balance and exercise capacity of stroke patients.

 

“Tai Chi has an overall beneficial effect on activities of daily living, balance, limb motor function, and walking ability among stroke survivors. . . and may also improve sleep quality, mood, mental health, and other motor function.” – Diyang Lyu

Abstract

Objective

This study aims to explore the influences of Tai Chi on the balance function and exercise capacity among stroke patients.

Methods

Databases including PubMed, Embase, WOS (Web of Science), the Cochrane Library, CNKI (China National Knowledge Infrastructure), Wanfang Data, VIP (VIP database), and CBM (China Biology Medicine disc) were retrieved to gather the figures of randomized controlled trials on the balance function and exercise capacity among stroke patients. Then relevant data were input and analyzed in Review Manager 5.3.

Results

Nineteen papers were included and analyzed in this study. According to the combined effect size, the balance function of stroke patients improved significantly: the Berg Balance Function Scale score [MD = 7.67, 95% CI (3.44, 11.90)]; standing and walking test scores [MD = 3.42, 95% CI (4.22, −2.63)]; gravity swing area [MD = 0.79, 95% CI (1.48, 0.10)]; and gravity swing speed [MD = −5.43, 95% CI (−7.79, 3.08)]. In addition, the exercise capacity improved significantly as well: the FMA (Fugl-Meyer Assessment Scale) scale score [MD = 4.15, 95% CI (1.68, 6.63)]. There are no significant influences or changes of other related results.

Conclusions

Stroke patients are able to improve their balance functions and exercise capacities prominently when they do Tai Chi exercise once or twice a week and ≥5 times/week and >30 ≤ 60 min/time.

Improve Attention in Older Individuals with Exercise and Mindfulness

Improve Attention in Older Individuals with Exercise and Mindfulness

 

By John M. de Castro, Ph.D.

 

“engaging in mindfulness meditation training improves the maintenance of goal-directed visuospatial attention and may be a useful strategy for counteracting cognitive decline associated with aging.” – Peter Malinowski

 

One of the primary effects of mindfulness training is an improvement in the ability to pay attention to the task at hand and ignore interfering stimuli. This is an important consequence of mindfulness training and produces improvements in thinking, reasoning, and creativity. The importance of heightened attentional ability to the individual’s ability to navigate the demands of complex modern life cannot be overstated. It helps in school, at work, in relationships, or simply driving a car. As important as attention is, it’s surprising that little is known about the mechanisms by which mindfulness improves attention

 

There is evidence that mindfulness training improves attention by altering the brain. It appears That mindfulness training increases the size, connectivity, and activity of areas of the brain that are involved in paying attention. A common method to study the activity of the nervous system is to measure the electrical signal at the scalp above brain regions. Changes in this activity are measurable with mindfulness training.

 

One method to observe attentional processing in the brain is to measure the changes in the electrical activity that occur in response to specific stimuli. These are called event-related, or evoked, potentials or ERPs. The signal following a stimulus changes over time. The fluctuations of the signal after specific periods of time are thought to measure different aspects of the nervous system’s processing of the stimulus. The N2 response in the evoked potential (ERP) is a negative going electrical response occurring between a 1 to 3 tenths of a second following the target stimulus presentation. The N2 component is thought to reflect cognitive control. The P3 response is a positive going electrical response occurring between a 3 to 6 tenths of a second following the target. The P3 component is thought to reflect attentional processing.

 

In today’s Research News article “Behavioral and ERP Correlates of Long-Term Physical and Mental Training on a Demanding Switch Task.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7940199/ ) Burgos and colleagues recruited healthy adults aged 44-65 years. They were separated into groups of participants who practiced for at least 5 years either Tai Chi, Meditation, aerobic exercise, meditation and exercise, or were sedentary. The participants performed a visuospatial task switch test that required the participants to respond to the position of a dot on a screen with the same or opposite hand or to switch back and forth between the two after 2 trials. This measures executive attention. As they were performing the task the electroencephalogram (EEG) was recorded and the evoked potentials to the dot recorded.

 

They found that on the visuospatial task switch test the Tai Chi and Meditation plus exercise groups performed best, the aerobic exercise group intermediate, and the sedentary group worst. Performance was measured by the reaction times on the switch trials and also on the proportionate change in reaction times on switch trials. In the evoked potentials in the frontal and parietal cortical areas, the groups that had mental plus physical training (Tai Chi and Meditation plus exercise groups) had significantly larger N2 responses on switch trials than the meditation or exercise alone groups. They also found that the larger the N2 response the better the performance on the switch task.

 

These are interesting results. But the groups were composed of people who chose to engage in these differing activities and the groups may be composed of people who differ in other ways other than the chosen activity. It would be best in future research if random assignment and training were used. Nevertheless, the results suggest that executive attention is best in people who practice mental and physical exercises. These are superior to either alone and particularly superior to being sedentary.  It was not studied here, but the better performance in attentional ability would predict better overall performance in life and resistance to the mental decline with aging.

 

Both the performance on the task and the N2 responses reflect better executive control of attention. This means that the participants who performed both mindfulness and physical exercise improved their ability to control attention. Mindfulness practices such as Tai Chi and meditation are known to alter the brain and improve attention. But the reason why exercise supplements these benefits is unknown. It is possible that exercise isn’t responsible for improvement but that sedentariness is responsible for deterioration and exercise acts to prevent this deterioration. Nevertheless, the results are clear mindfulness plus physical activity alters the brain in such a way as to improve the individual’s ability to control attention.

 

So, improve attention in older individuals with exercise and mindfulness.

Abstract

Physical and mental training are associated with positive effects on executive functions throughout the lifespan. However, evidence of the benefits of combined physical and mental regimes over a sedentary lifestyle remain sparse. The goal of this study was to investigate potential mechanisms, from a source-resolved event-related-potential perspective, that could explain how practicing long-term physical and mental exercise can benefit neural processing during the execution of an attention switching task. Fifty-three healthy community volunteers who self-reported long-term practice of Tai Chi (n = 10), meditation + exercise (n = 16), simple aerobics (n = 15), or a sedentary lifestyle (n = 12), aged 47.8 ± 14.6 (SD) were included in this analysis. All participants undertook high-density electroencephalography recording during a switch paradigm. Our results indicate that people who practice physical and mental exercise perform better in a task-switching paradigm. Our analysis revealed an additive effect of the combined practice of physical and mental exercise over physical exercise only. In addition, we confirmed the participation of frontal, parietal and cingulate areas as generators of event-related-potential components (N2-like and P3-like) commonly associated to the performance of switch tasks. Particularly, the N2-like component of the parietal and frontal domains showed significantly greater amplitudes in the exercise and mental training groups compared with aerobics and sedentary groups. Furthermore, we showed better performance associated with greater N2-like amplitudes. Our multivariate analysis revealed that activity type was the most relevant factor to explain the difference between groups, with an important influence of age, and body mass index, and with small effects of educational years, cardiovascular capacity, and sex. These results suggest that chronic combined physical and mental training may confer significant benefits to executive function in normally aging adults, probably through more efficient early attentional processing. Future experimental studies are needed to confirm our results and understand the mechanisms on parieto-frontal networks that contribute to the cognitive improvement associated with practicing combined mental and aerobic exercise, while carefully controlling confounding factors, such as age and body mass index.
