What will I experience if I participate in this study? If eligible, participants will be randomly assigned by physicians to one of two study phases: the screening and baseline assessment phase, or the intervention and follow-up phase. The trial consists of three phases, each containing two phases (experimental or control, lasting 1-2 weeks). After enrollment, participants will be randomly assigned to either the Tai Chi intervention group or the walking control group. Throughout the study, participants must cooperate with physicians to complete relevant questionnaires and attend scheduled follow-up visits.

What might be the benefits of participating in this study? The research team will cover all expenses for the exercise program. Participants will receive free exercise training, physiological counseling, and standardized assessments throughout the study, including follow-up sessions. Our previous sports medicine research shows that 12 weeks of Tai Chi therapy can significantly improve insomnia symptoms.

What are the risks of participating in this study? Participants who have not exercised for a long time may have adverse reactions such as muscle pain and joint pain caused by exercise in the early stage of the experiment or during the study, or even lead to the termination of the experiment.

Is participation in this study mandatory? No, participation in this study is entirely voluntary.

Can I quit the study midway? Yes, you can opt out at any time, and this will not affect your legal right to continue regular checkups or treatments.
