Objective To systematically summarize exercise interventions following bariatric surgery and provide references for clinical practice. Methods Guided by the scoping review framework, original studies on exercise interventions following bariatric surgery were systematically searched in domestic and international databases, from database inception to November 27, 2024. Results Twenty-two studies (19 RCTs, 3 quasi-experimental) were included. Exercise modalities included aerobic exercise, resistance training, core stability training, and balance training, etc.; 15 studies used multimodal programs. Exercise intensity was prescribed via maximal heart rate, heart rate reserve, and perceived exertion scales. Exercise dosage were: frequency 2-5 sessions/week, duration 30-60 min/session, and program length 4-44 weeks. No major adverse events reported in 7 safety-monitored studies. However, there was lack of standardized criteria for evaluating exercise adherence. Exercise interventions demonstrated positive effects on body composition, physical function, metabolic outcomes, and quality of life in post-bariatric surgery patients. Conclusion Exercise interventions demonstrate feasibility and efficacy for post-bariatric patients, yet exhibit substantial heterogeneity in prescription parameters (modalities, intensity, duration, and frequency).Future research should optimize exercise protocol and evaluate long-term outcomes to maximize sustained weight loss and prevent weight regain.
