摘要:Prostate cancer is one of the most common cancers in men which does negative effects on musculoskeletal system. The purpose of this study was to investigate the effect of resistance training on balance and flexibility of patients with prostate cancer. Twenty-two men with non-metastatic prostate cancer from Isfahan voluntarily participated in this study. Patients were randomly assigned into an intervention group and control groups. Patients in experimental group participated in a resistance exercise program for 10 weeks but control group followed their normal treatment program. Before and after this period static balance (open and close eyes) and flexibility of all patients were evaluated. Results were analyzed using independent and dependent t-test. A significant improvement (P< 0.05) in balance in dominant leg (opened and closed eyes) was observed in experimental group and also in non-dominant leg only with closed eyes, but no change in control group. Flexibility improved significantly (P< 0.05) in experimental group but not in control group. It can be concluded that resistance training does positive effects on balance and flexibility in patients with prostate cancer, so it can be recommended as a modality for these patients.
