AIMS To review the content and efficacy of physical activity (PA) for cancer-related fatigue (CRF) among colorectal cancer survivors. DESIGN Systematic review. METHODS A comprehensive search for randomized controlled trials from inception to April 1, 2022, of the following database was performed: EMBASE, PubMed, Web of Science, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang Data and China Biology Medicine (CBM). RevMan5.4 software was used for performing meta-analysis. RESULTS A total of eight qualified randomized controlled trials that included 542 survivors were included. PA interventions significantly reduced the CRF (SMD = -0.46; 95% CI: [-0.76, -0.15], Z = 2.67, p = 0.003); Subgroup analysis showed that fatigue was significantly improved when the length of interventions was at least 6 months and the weekly duration of PA was less than 150 min/week (SMD = -0.54; 95% CI: [-0.81, -0.27], Z = 3.87 and p = 0.0001; SMD = -0.67; 95% CI: [-1.15, -0.19], Z = 2.74 and p = 0.006); PA intervention with the length of <6 months and the volume of ≥150 min/week did not reduce fatigue (p > 0.05).
