The goal of this clinical trial is to learn if a 12-week Baduanjin exercise program can improve health in sedentary young and middle-aged adults. The main questions it aims to answer are:
1. Does the Baduanjin program improve participants' cardiorespiratory fitness (measured as peak oxygen uptake)?
2. Does it improve their body composition, muscle strength, balance, and flexibility?
3. Does it reduce their daily sitting time?
Researchers will compare the Baduanjin training group to a health education control group to see if Baduanjin is more effective in improving these health outcomes.
Participants will:
1. Be randomly assigned to one of the two groups.
2. If in the Baduanjin group, attend supervised group sessions and practice at home for 12 weeks.
3. Complete a series of assessments at the beginning, middle, and end of the study, including fitness tests, body measurements, and questionnaires.
