BACKGROUND: Lifestyle factors are closely associated with the onset and progression of inflammatory bowel disease (IBD). Studies have demonstrated the positive effects of exercise on clinical outcomes and quality of life in individuals with IBD. Despite the well-documented role of exercise in improving IBD outcomes, the underlying mechanisms remain unclear.
AIM: To compare the efficacy of different exercise modalities and explore their potential physiological mechanisms in rodent models of colitis.
METHODS: We conducted a comprehensive search of five databases from inception to September 24, 2024, which yielded 19 animal studies in rodent colitis models. We compared the efficacy of various forms of exercise and explored the possible physiological mechanisms. The effects of different exercise modalities, namely forced treadmill running (FTR), voluntary wheel running (VWR), swimming, climbing, and jumping, on both macroscopic symptoms (e.g., body weight, disease activity, and colon length) and microscopic parameters (e.g., histopathology, immune markers, oxidative/antioxidant balance, and gut microbiota) in colitis models were compared.
RESULTS: VWR (simulated recreational physical activity), swimming (aerobic exercise), and strength training (climbing and jumping) consistently promoted overall health in animal colitis models. However, evidence for FTR remains inconsistent, with a notable number of studies suggesting potential exacerbation of colitis symptoms, possibly due to stress or fatigue resulting from its coercive nature. Overall, various exercise (e.g., VWR, swimming, strength training) ameliorates colitis symptoms possibly by suppressing immune hyperactivation, enhancing antioxidant defenses, and modulating gut microbiota composition. In contrast, FTR was inconsistent, with several studies indicating a potential exacerbation of colitis symptoms, possibly due to stress or fatigue induced by its coercive nature.
CONCLUSION: Exercise modality is critical in influencing colitis outcomes, with voluntary and low-stress forms generally being beneficial, while forced exercise may yield adverse effects. These findings highlight the importance of exercise type and individual tolerance in designing therapeutic exercise interventions for IBD. Further research is warranted to establish a robust therapeutic framework for exercise-based interventions in IBD management.
