ADVERSE REACTIONS
To ensure that each participant could apply the TRF approach and walking exercise program independently, a thorough description of both activities was provided to all participants prior to trial commencement. During the intervention, weekly communication was conducted with the participants, and any adverse reactions experienced by the intervention groups were recorded. Participants who experienced serious adverse reactions were asked to discontinue participation. Simultaneously, the research team supervised the intervention by asking the participants to upload their diet and exercise data daily to the WeChat platform to promptly detect problems and provide targeted assistance.
