Abstract
INTRODUCTION: Exercise intensity, breathing patterns, and intentional meditation significantly influence autonomic nervous system activity. Tai Chi serves as an aerobic exercise stimulus. Additionally, it incorporates a distinctive breathing pattern. It is also seen as a meditative exercise. However, the acute effect of different Tai Chi factors on autonomic activity is unclear. OBJECTIVE: This study aims to investigate the acute effects of Tai Chi with different practice emphasis on autonomic activity. The findings may guide the selection of Tai Chi techniques in exercise prescription. METHODS: After health screening, 8 Traditional Chinese Medicine students (TCMS), 8 Competitive Tai Chi students (CTCS), and 9 Economics and Management students (EMS) were enrolled. Participants were assessed for indices related to autonomic activity, exercise intensity, respiration, and mind state during both quiet and Tai Chi conditions. RESULTS: Results indicated that the RMSSD and SDNN values for TCMS were significantly higher than those of CTCS and EMS (P < 0.05). Heart rate was not significantly different between the groups during quiet and Tai Chi states (P > 0.05). Immediately following Tai Chi practice, TCMS exhibited significant reductions in thoughtfulness, anger, and inactivity (P < 0.05). No significant differences were noted in CTCS and EMS (P > 0.05). CONCLUSION: Tai Chi practices emphasizing mindfulness may be more effective in enhancing autonomic activity. It recommends the standing poles interventions for depression, insomnia, and other groups for more autonomic health benefits.
