“Long term regular [Tai Chi] exercise has favourable effects on the promotion of balance control, flexibility, and cardiovascular fitness in older adults.” – Youlian Hong

The aging process involves a systematic progressive decline in every system in the body, the cardiovascular system and respiratory system included. The elderly frequently also 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.

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. Tai Chi practice has been found to be effective for an array of physical and psychological issues. Tai Chi has 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 on the effects of Tai Chi training on the cardiorespiratory system of older adults has been accumulating. So, it makes sense to summarize what has been learned.

In today’s Research News article “A Systematic Review and Meta-Analysis of Tai Chi Training in Cardiorespiratory Fitness of Elderly People.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8942636/ ) Tan and colleagues review and summarize the published research randomized controlled trials on the effects of Tai Chi training on the cardiorespiratory system of older adults (> 50 years of age). They identified 24 published research studies.

They report that the published randomized controlled trials found that Tai Chi training produced significant increases in heart rate, VO_{2 max}(the maximum amount of oxygen your body can utilize during exercise) and O_{2 pulse} (oxygen consumed per heart beat, a measure of stroke volume), and vital capacity (the greatest volume of air that can be expelled from the lungs after taking the deepest possible breath). The increase in vital capacity was significantly larger in participants who practiced for 48 weeks and over.

The results are clear. Tai Chi training produces improves cardiorespiratory function in older adults. Thus suggests that Tai Chi training can help overcome or delay age-related physical decline.

Abstract

Objectives

The purpose of this study was to investigate the influence of Tai Chi on cardiorespiratory fitness (CRF) in elderly people using meta-analysis.

Methods

This study used seven electronic databases and data retrieved from randomized controlled trials (RCTs) investigating the role of Tai Chi on CRF in the elderly. All these 24 RCTs were screened and selected from 7 literature databases. The Stata 11.2 software (StataCorp, USA) was used for the meta-analysis, subgroup analysis, and bias test, while the Cochrane Collaboration’s tool was used for the assessment of the risk of bias (RoB). 4 researchers independently participated in sample selection, data extraction, and RoB assessment.

Results

Following the inclusion criteria, 24 eligible studies were included in our analysis. The meta-analysis indicated that Tai Chi practice significantly increased the maximum rate of oxygen consumption (VO2 max) (weighted mean difference (WMD) = 3.76, 95% CI: 1.25 to 6.26, P < 0.1), leading to an overall reduction in the heart rate (HR) (WMD = −1.84, 95% CI: −2.04 to −1.63, P ≤ 0.001) and an increase in the O2 pulse (WMD = 0.94, 95% CI: 0.60 to 1.28, P ≤ 0.001) in individuals who practiced Tai Chi regularly compared with those who did not. The subgroup analysis suggested that overall in those who practiced Tai Chi, males (WMD = 1.48, 95% CI: 0.85 to 2.12, P ≤ 0.001) had higher O2 pulse than females (WMD = 0.73, 95% CI: 0.33 to 1.12, P ≤ 0.001). The subgroup analysis also showed an increase in the vital capacity (VC) (WMD = 316.05, 95% CI: 239.74 to 392.35, P ≤ 0.001) in individuals practicing Tai Chi. When the samples were further stratified by Tai Chi practicing time, the subgroup analysis suggested that individuals practicing Tai Chi over a period of 24 weeks showed no significant difference in VC (WMD = 82.95, 95% CI: -98.34 to 264.23, P=0.370), while those practicing Tai Chi over a period of 48 weeks showed a significant increase (WMD = 416.62, 95% CI: 280.68 to 552.56, P ≤ 0.001). Furthermore, the subgroup analysis demonstrated that the increase in VC is significantly correlated with the Tai Chi practicing time (WMD = 344.97, 95% CI: 227.88 to 442.06, P ≤ 0.001).

Conclusion

Regular Tai Chi practice could improve the CRF in the elderly, as indicated by significant improvement in indicators including VO2max, O2pulse, VC, and HR. However, gender and practice time might influence the overall beneficial outcomes.

Mindful Doctors are Better Doctors

By John M. de Castro, Ph.D.

“Mindfulness enables doctors to listen to a patient without judging, to be present, responding to what the patient is saying and feeling and also aware of what they’re feeling.”- Ron Epstein

Stress is epidemic in the western workplace with almost two thirds of workers reporting high levels of stress at work. In high stress occupations, like healthcare, burnout is all too prevalent. Burnout is the fatigue, cynicism, emotional exhaustion, sleep disruption, and professional inefficacy that comes with work-related stress. It is estimated that over 45% of healthcare workers experience burnout. It not only affects the healthcare providers personally, but also the patients, as it produces a loss of empathy and compassion. Burnout, in fact, it is a threat to the entire healthcare system. Currently, over a third of healthcare workers report that they are looking for a new job. Hence, burnout contributes to the shortage of doctors and nurses.

Preventing burnout has to be a priority. Unfortunately, it is beyond the ability of the individual to change the environment to reduce stress and prevent burnout. So, it is important that methods be found to reduce the individual’s responses to stress; to make the individual more resilient when high levels of stress occur. Contemplative practices have been shown to reduce the psychological and physiological responses to stress and improve well-being. Indeed, mindfulness has been shown to be helpful in treating and preventing burnout, increasing resilience, and improving sleep. Thus there is a need to investigate how mindfulness effects doctors’ well-being and the well-being of their patients.

In today’s Research News article “). Effects of Mindfulness Meditation on Doctors’ Mindfulness, Patient Safety Culture, Patient Safety Competency and Adverse Event.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8954148/ ) Liu and colleagues recruited doctors from hospitals and randomly assigned them to receive either 8-weekly 90-minute sessions of mindfulness meditation along with home practice or to a no-treatment control condition. They were measured before and after training for mindfulness, patient safety competency, hospital safety culture, and adverse medical events.

They found that in comparison to baseline and the no-treatment control doctors, the group that received mindfulness training had significantly greater levels of mindfulness, patient safety competency, and hospital safety culture and significantly lower rates or adverse medical events.

Hence mindful meditation made the doctors better at patient safety including lower rates of bad outcomes. In other words, mindful doctors are better doctors.

“Anyone whose work involves immense human suffering needs to be aware of their inner life. The nature of the work that physicians do makes [them] more vulnerable to negative emotions or making errors,” – Ron Epstein

Abstract

Objective: This study investigated the effects of mindfulness meditation on doctors’ mindfulness, patient safety culture, patient safety competency, and adverse events. Methods: We recruited 91 doctors from a hospital in China and randomized them to mindfulness meditation group (n = 46) and a waiting control group (n = 45). The mindfulness meditation group underwent an 8-week mindfulness meditation intervention, while the control group underwent no intervention. We measured four main variables (mindfulness, patient safety culture, patient safety competency, and adverse event) before and after the mindfulness meditation intervention. Results: In the experimental group, mindfulness, patient safety culture and patient safety competency were significantly higher compared with those of the control group. In the control group, there were no significant differences in any of the three variables between the pre-test and post-test. Adverse events in the experimental group were significantly lower than in the control group. Conclusions: The intervention of mindfulness meditation significantly improved the level of mindfulness, patient safety culture and patient safety competency. During the mindfulness meditation intervention, the rate of adverse events in the meditation group was also significantly lower than in the control group. As a simple and effective intervention, mindfulness meditation plays a positive role in improving patient safety and has certain promotional value.
