Impact of Tai Chi and Aerobic Exercise on Cognitive Function, Balance, Cardiovascular Fitness, and Quality of Life in Older Adults: Randomized Control Trial.

Abstract

Introduction Tai chi, an ancient Chinese martial art, was originally developed for combat and self-defense. Over time, it has evolved into both a sport and a form of exercise. This gentle, low-impact exercise involves performing a series of deliberate, flowing motions while focusing on deep, slow breaths. This study investigates the effects of chen tai chi and aerobic exercises on cognition, balance, cardiopulmonary fitness, and quality of life in older adults. Methodology This study employed a single-blinded randomized control trial design, enrolling 60 participants aged between 60 and 75 years. Participants were divided into three groups: Group A (aerobics), Group B (chen tai chi), and Group C (control). Exercise sessions were held four days per week over a period of four weeks. Evaluations included the Montreal Cognitive Assessment for cognition, a one-leg stand test for static balance, a Timed Up and Go Test for dynamic balance, a six-minute walk test for cardiopulmonary fitness, and a health-related quality-of-life scale. Assessments were conducted at baseline, immediately after the intervention, and at follow-up was taken after eight weeks. Results Post-intervention, improvements were observed in cognition and static balance across all groups. Within-group analysis revealed that the aerobics group experienced statistically significant enhancements in cognition (p = 0.0001) and static balance (p = 0.01). Although no statistically significant differences were found between groups in terms of dynamic balance, cardiopulmonary fitness, and quality of life, the within-group analysis showed significant improvements in the aerobics group in dynamic balance (p = 0.0009), cardiopulmonary fitness (p = 0.03), and quality of life (p = 0.0001). Conclusion Compared to chen tai chi and no intervention, the study concludes that aerobic exercise has a more pronounced effect on improving cognition, balance, cardiopulmonary fitness, and quality of life in older adults. Aerobic exercise is recommended as an effective method to prevent frailty and promote independence among the elderly.
