Introduction: The practice of Tai-ji has shown a positive effect on the physical functions of the elderly and has been promoted as a recommended daily activity for middle-aged and elderly individuals. However, there is still no scientific evidence about its cardiorespiratory benefits. Objective: Study the effect of Tai-ji on the cardiorespiratory function and physical fitness of the elderly. Methods: A group of elderly people from the same community and in good health, considered suitable for sports experiments was divided into the experimental group for Tai-ji exercise and the control group for vigorous walking exercise. Each week, the Tai-ji exercise with eight steps and the vigorous walking exercise was performed three times in each group. Results: After six weeks of Tai-ji exercise with eight steps of five methods, the vital capacity, maximal oxygen consumption, maximal voluntary ventilation, and oxygen pulse of the experimental group were significantly increased, and the systolic and diastolic pressures were significantly reduced, evidencing an improvement in the performance of the cardiopulmonary function. Conclusion: Tai-ji exercise is beneficial for the cardiopulmonary function and physical health of the elderly and is scientifically useful for improving the mental health level and quality of life of the elderly. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
Introduction: According to the background of the healthy aging population and national fitness care, rapid development has begun in national sports in China. This development is the result of current research on the current scenario. Objective: Study the effects of exercise on the rehabilitation of middle-aged and elderly people with sports injuries. Methods: Twenty individuals were recruited for the experiment; the experimental group received the rehabilitation exercise protocol three times a week for four weeks, while the control group maintained the original lifestyle with no exercise or vigorous exercise. Results: It was found that there was no significant difference in height, weight, and body fat percentage after the aerobic exercise intervention training protocol (P>0.05), but there was a significant difference in BMI between the experimental group and the control group after the intervention training period (P<0.05). The VAS score of the experimental group before and after training decreased from 5.49 to 0.90, showing a significant effect, indicating a significant difference between the experimental group before and after training (P<0.05). Conclusion: The research shows that exercise positively affects the prevention and rehabilitation of sports injuries. The results obtained can help groups in national fitness. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
