A significant negative association was found between aerobic exercise intensity and fatigue reduction .
A peak effect was found for moderate-intensity aerobic exercise for improving walking endurance .
No dose-response relationship was found between exercise and markers of inflammation or exercise duration and outcomes .
Rates of adherence were typically high and few adverse events were reported .
Exercise is safe , reduces fatigue and increases endurance in cancer survivors .
QUESTION Is there a dose-response effect of exercise on inflammation , fatigue and activity in cancer survivors ?
A 4-week home-based aerobic and resistance exercise program during radiation therapy: a pilot randomized clinical trial.
During radiation therapy , cancer patients may report  cancer-related fatigue ( CRF ) , which impairs aerobic capacity , strength , muscle mass , and , ultimately , quality of life ( QOL ) . The purpose of this pilot clinical trial was to examine the feasibility and initial efficacy of a home-based aerobic and progressive resistance exercise intervention for aerobic capacity , strength , muscle mass , CRF , and QOL . Daily steps walked ( DSW ) , daily minutes of resistance exercise ( MRE ) , and number of resistance exercise days ( RED ) were assessed to evaluate intervention adherence . Breast and prostate cancer patients ( n = 38 ) beginning radiation therapy  were r and omized to undergo 4 weeks of exercise or no exercise . Participants in the exercise group demonstrated good adherence to the exercise intervention , with significantly more DSW , MRE , and RED at post intervention and 3 month follow-up than controls . Participants in the exercise intervention exhibited significantly higher QOL and significantly lower CRF post intervention and at 3-month follow-up than controls . Results of this pilot study provide positive preliminary evidence that exercise during radiation may be beneficial for cancer patients
