Androgen deprivation therapy is a common treatment for prostate cancer. However, this therapy is associated with various adverse effects, such as increased body fat and decreased bone mineral density. Exercise may be useful for ameliorating these adverse effects, although it is not completely effective. This review aimed to clarify how exercise interventions influenced body composition and bone mineral density and to explore the most effective exercise program among prostate cancer patients who received androgen deprivation therapy. We searched the PubMed, Embase, Web of Science, EBSCO, and Cochrane Library databases for reports of randomised controlled trials that were published until October 2021. All studies involved prostate cancer patients who received androgen deprivation therapy and completed aerobic exercise, resistance exercise, and/or impact exercise training. Outcomes were defined as lean body mass, body fat mass, body fat rate, regional and whole-body bone mineral density. Thirteen reports regarding 12 randomised clinical trials (715 participants) were included. Relative to the control group, exercise intervention provided a higher lean body mass (mean difference 0.88, 95% confidence interval 0.40 to 1.36, p < 0.01), a lower body fat mass (mean difference -0.60, 95% confidence interval -1.10 to -0.10, p < 0.05), and a lower body fat rate (mean difference -0.93, 95% confidence interval -1.39 to -0.47, p < 0.01). Subgroup analyses revealed greater efficacy for exercise duration of >= 6 months (versus < 6 months) and exercise immediately after the therapy (versus delayed exercise). No significant differences were observed in the bone mineral density outcomes. Exercise can help ameliorate the adverse effects of androgen deprivation therapy in body composition, with combination exercises including resistance exercise, 8 to 12 repetition maximum of resistance exercise intensity, prolonged exercise duration, and performing exercise immediately after therapy providing better amelioration. And the combination of resistance and impact exercise appears to be the best mode for improving the bone mineral density.
