Androgen-deprivation therapy (ADT) for prostate cancer (PCa) has side effects that significantly impair health-related quality of life (HRQOL). Exercise ameliorates many side effects of ADT, but different modalities, particularly in the home-based setting, have not been well studied. In this study the authors randomly assigned 66 PCa survivors receiving ADT to 6 mo of home-based aerobic or resistance training. Psychosocial well-being and physical fitness were measured at baseline, 3 and 6 mo, and then 6 mo postintervention. Intention-to-treat analyses showed that fatigue and HRQOL were not significantly different between groups; however, in a per-protocol analysis the resistance-exercise training group demonstrated clinically significant improvements in HRQOL. Differential within-group effects on physical fitness were also observed at various time points. At all time points, the aerobic-training group engaged in significantly more physical activity than the resistance-training group, a finding that should be further examined given evidence-based guidelines for activity volume in cancer survivors.
