The aim of this study is to evaluate the effectiveness of multicomponet exercise for reversing pre-frailty among Chinese community-dwelling pre-frail older adults.Meanwhile,to explore the effects of multicomponent exercise on self-efficiency of exercise.

Based on the Wellness Motivation Theory (WMT), this study aimed to develop a theoretical model of exercise intervention for the pre-frail elderly. This study was to establish an exercise intervention mode, conduct empirical research through randomized controlled trials, and propose improvement strategies, aiming at improving the effectiveness of health management services for the community-dwelling pre-frail elderly. Specific research objectives are as follows:

1. To develop a theoretical model of exercise intervention for the pre-frail elderly based on the WMT, and to explain the operation mechanism of the exercise intervention mode.
2. An empirical study was conducted to verify the applicability and effectiveness of the exercise intervention mode, analyze the influencing factors of the intervention effect, and propose optimization strategies to improve the exercise intervention effect of the elderly in pre-frailty.
