Purpose: The purpose of the present study was to examine the effects of a 24-week Tai Chi exercise intervention on balance and other physical changes such as flexibility and reaction time (RT) among healthy older males. Methods: Thirty-eight male subjects aged 55e65 years without prior Tai Chi experience were recruited from a local community in Shanghai, China. A 60-min Tai Chi exercise session was performed three times a week for 24 weeks. Changes in RT, sit-and-reach flexibility and balance (static balance with eyes open and closed respectively) were measured before and after the Tai Chi intervention. Results: After the 24-week Tai Chi intervention, the choice RT ( p < 0.05) decreased, and sit-and-reach flexibility improved ( p < 0.01) over the pre-test (7.8 AE 6.2 vs. 7.1 AE 3.0 cm). Sway length, area, X-axis deviation amplitude and Y-axis deviation amplitude performance decreased significantly after the intervention with a double-foot stance with eyes open ( p < 0.05). Sway length, area and average sway speed showed a statistically significant decrease after the intervention with the double-foot stance with eyes closed. In the single-foot stance with eyes open condition, sway length and average sway speed showed a statistically significant decrease ( p < 0.05). Conclusion: The 24-week Tai Chi exercise intervention had a positive influence on balance control in older males.
Background. Postmenopausal osteoporosis (PMOP) is a common disease in older women that can severely jeopardize their health. Previous studies have demonstrated the effect of Er xian decoction (EXD) or Baduanjin exercise (BE) on PMOP. However, reports on the effect of EXD combined with BE on PMOP are limited. This study aimed to investigate the impact of EXD combined with BE on bone mineral density (BMD), lower limb balance, and mental health in women with PMOP. Methods. A 1 : 1 : 1 simple randomization technique was employed. Fifty participants with postmenopausal osteoporosis were allocated to three groups: the EXD group (EXD = 15); the BE group (BE = 18); and the combined group (EXD + BE = 17). After both 8 weeks and 16 weeks of intervention treatment, participants improved significantly with respect to BMD and the one-leg standing test (OLST), Berg balance scale (BBS), timed up and go (TUG) test, self-anxiety scale (SAS), and self-rating depression scale (SDS). The results were used to compare the effect of the intervention on BMD, lower limb balance function, and mental health in patients with PMOP. Results. Compared to the EXD and BE groups, the EXD + BE group showed the strongest effects on BMD, lower limb balance function, and mental health ( p < 0.01 ). A correlation between BMD and lower limb balance and mental health was noted in the EXD + BE group. The change in mental health (SAS score) was correlated with BMD (femoral neck) improvement. Conclusions. The present study demonstrates that EXD combined with BE (EXD + BE) may have a therapeutic advantage over both monotherapies for treating BMD, lower limb balance function, and mental health in patients with PMOP. The feasibility of the approach for a large-scale RCT was also confirmed. Er xian decoction combined with Baduanjin exercise (EXD + BE) might offer a viable treatment alternative for participants with postmenopausal osteoporosis given its promising effects in disease control and treatment, with good efficacy and safety profiles.
Objectives: The present study proposes a model for the relationships among competitive martial arts players' positive emotions, hope (path and emotive force ideas), sense of control, self-handicapping, and precompetition state anxiety (PCSA). The model seeks to advance our understanding around the causal and mediating effects between these variables and, thus, has important implications for theory and practice in the field of sports and exercise psychology. Method: A total of 327 participants (male: 255, female: 72; age: 21.45 ± 2.78 years; athletic training: 6.27 ± 2.54 years) in the China University Wushu Sanda Championship 2019 were surveyed. Within 2 h before the match, PCSA, sports hope, sense of control, anxiety, and self-handicapping were measured. Results: The findings of the present study showed that (1) positive emotions have a significant positive correlation with path and emotive force ideas, anxiety orientation, ability to cope, goal attainment, and sense of control; (2) path and emotive force ideas were significantly positively correlated with anxiety orientation, ability to cope, goal attainment, and sense of control and significantly negatively correlated with anxiety intensity and self-handicapping; and (3) the path idea acted as a partial negative mediator between positive emotion and anxiety intensity, and the sense of control played a partial negative mediator between the emotive force idea and self-handicapping. Conclusion: (1) Players' positive emotions can predict the sense of hope. It also tends to interpret the anxiety intensity as a positive challenge rather than a negative sense of control. (2) Players with a higher path idea also tend to have lower negative emotion, anxiety intensity, and self-handicapping; (3) martial arts players' path idea has a significantly higher predictive power for the sense of control than the emotive force idea. Still, both path and emotive force ideas can indirectly affect the intensity of anxiety orientation and self-handicapping through the multiple mediators of sense of control. Finally, recommendations for coaches related to training and preparation for competition are discussed.
Review question / Objective: Patient: Inclusion criteria:(1) New York Heart Association (NYHA) classification I ~ III; (2) 40 years old ≤ age < 70 years old; (3) no h e m o d y n a m i c d i s o r d e r ; ( 4 ) g o o d compliance. Intervention: The intervention methods of the experimental group were mind-body exercise, including Tai Chi, yoga, Qigong, meditative movement, etc. The control group included usual care, no physical activity, and no-intervention control group and other different types. Outcomes: The purpose of this metaanalysis is to evaluate the effects of mindbody exercise on the cardiopulmonary function, blood pressure, heart rate and INPLASY 1
