The study aimed to discuss the influences of 24-form Tai Chi on cardio-pulmonary functions, exercise performances, and cognitive functions of the aged.
Forty old people in Pingdingshan of China were selected through convenient sampling method from 2020 to 2021. They were randomly divided into the observation group (n=20) and the control group (n=20). The observation group exercised 24-form Tai Chi for 8 weeks, three times per week, 45 min per session. The respondents were evaluated by cardiopulmonary exercise testing, sitting-standing test, 6-min walking test, and the Berg balance scale. The P300 test was performed to evaluate the cognitive functions of respondents.
After the intervention, the observation group was significantly (P<0.05) superior to the control group concerning maximal oxygen consumption, anaerobic threshold, vital capacity, stroke volume (SV), cardiac output (CO), left ventricular end-diastolic diameter (LVEDD), left end-diastolic velocity (EDV), sitting-standing test, 6-min walking test, and the Breg balance function scores, showing statistically significant differences (P<0.05). The content of body fat and body mass index (BMI) of the observation group decreased significantly, whereas muscle mass and fat-free mass increased dramatically, which were however significantly lower than those of the controlled group (P<0.05). Moreover, the P3b amplitude of the observation group increased significantly (P<0.05) and was significantly higher than that of the control group (P<0.05).
The 24-form Tai Chi not only improves cardio-pulmonary functions and exercise performances of the aged but also increases cognitive functions of the aged.
