Effect of Tai Chi on Single-leg Balance in a Sedentary

Each subject was required to meet the criteria of sitting and lying down for an average of at least 7 hours per day for the past 1 month, with no exercise habits. Tai chi was used as the primary exercise intervention. The training was administered three times a week for 16 weeks. The control group would be required to submit the Sedentary Behavior Questionnaire weekly and ensure similar lifestyle habits as before. We measured subjects' dual-task single-leg balance using the Tecnobody-PK252 balance apparatus before and after 16 weeks, and their attentional ability using the attention network test.

Results: Tai chi significantly improved dual-task single-leg balance and attention in the sedentary group (p < 0.05). There was a significant difference compared to the control group. A correlation was found between improved attentional ability and sway path scores.
