Abstract Background Inflammatory bowel disease (IBD) is a chronic relapsing–remitting condition that impairs health-related quality of life (HRQoL), even in remission. Beyond physical symptoms, IBD is associated with anxiety, depression, and persistent fatigue, affecting up to 70% of patients during flares and 40% in remission1. Despite its impact, specific therapies for chronic fatigue in IBD are lacking. Physical exercise has shown benefits in other immune-mediated diseases2,3, but data in IBD are limited. A previous pilot study from our research group of a 12-week supervised exercise programme improved fatigue, HRQoL, and fitness4. This study, a randomised controlled trial, was needed to validate these findings. Methods In a multicentre, randomised trial, adults (18–67 years) with quiescent IBD and chronic fatigue (≥3 months; IBD-F section I ≥ 11) were randomised 1:1 either or control group. The intervention comprised a 12-week supervised exercise programme with three one-hour personalised sessions per week of 30 min aerobic training and 30 min resistance training and included cardiopulmonary exercise testing pre- and post-intervention. Controls received standard care and written advice about daily exercise. Primary outcomes were fatigue (IBD-F) and HRQoL (IBDQ) at 12 weeks. Secondary outcomes included anxiety and depression (HADS), sleep quality (PSQI), cardiorespiratory fitness, body composition, disease activity, and adverse events. Results In total, 100 patients were randomised. Of them, 93 participants completed the study and were included in the analysis (mean age 43.5 ± 11.4 years; 73% female; 61% CD, 37% UC, 2% IBD-U). Fatigue decreased more in the intervention group as compared to the control group (adjusted mean 36.5 ± 2.6 vs 45.3 ± 2.6; p = 0.014, respectively) and HRQoL increased more in the intervention group as compared to the control group (adjusted mean 175.6 ± 2.9 vs 166.6 ± 2.9; p = 0.024, respectively), both remaining significant after Bonferroni correction. Anxiety (HADS-A) decreased (p = 0.02). Cardiorespiratory fitness improved in the intervention group as compared to pre-intervention measurements (VO2max p 0.001, maximum power p 0.001, heart rate recovery after 2 min p = 0.014) and body fat decreased (p = 0.024). Depressive symptoms (HADS-D) and sleep quality showed no group differences. Conclusion This 12-week personalised, supervised exercise programme significantly reduced fatigue and improved HrQoL in patients with quiescent IBD and chronic fatigue. Significant improvements were also observed in anxiety and physical fitness. Exercise could be an effective strategy for managing IBD-related fatigue. References: 1.
