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 ?
Exercise manages fatigue during breast cancer treatment: a randomized controlled trial.
Fatigue is the most prevalent and debilitating symptom experienced by breast cancer patients receiving adjuvant chemotherapy or radiation therapy and few evidence -based treatments are available to manage this distressing side-effect . The purpose of this multi-institutional r and omized controlled trial was to determine the effects of exercise on fatigue levels during treatment for breast cancer . Sedentary women ( N=119 ) with Stage 0-III breast cancer receiving outpatient adjuvant chemotherapy or radiation therapy were r and omized to a home-based moderate-intensity walking exercise program or to usual care for the duration of their cancer treatment . Of participants r and omized to exercise , 72 % adhered to the exercise prescription ; 61 % of the usual care group adhered . The intention-to-treat analysis revealed no group differences in part because of a dilution of treatment effect as 39 % of the usual care group exercised and 28 % of the exercise group did not . When exercise participation was considered using the data analysis method of instrumental variables with principal stratification , a clinical ly important and statistically significant ( p=0.03 ) effect of exercise on pretest-to-posttest change in fatigue levels was demonstrated . Adherence to a home-based moderate-intensity walking exercise program may effectively mitigate the high levels of fatigue prevalent during cancer treatment
