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 ?
Impact of a home-based walking intervention on outcomes of sleep quality, emotional distress, and fatigue in patients undergoing treatment for solid tumors.
Exercise use among patients with cancer has been shown to have many benefits and few notable risks . The purpose of this study was to evaluate the impact of a home-based walking intervention during cancer treatment on sleep quality , emotional distress , and fatigue . Methods . A total of 138 patients with prostate ( 55.6 % ) , breast ( 32.5 % ) , and other solid tumors ( 11.9 % ) were r and omized to a  home-based walking intervention or usual care . Exercise dose was assessed using a five-item subscale of the Cooper Aerobics Center Longitudinal Study Physical Activity Question naire . Primary outcomes of sleep quality , distress , and fatigue were compared between the two study arms . Results . The exercise group ( n = 68 ) reported more vigor ( p = .03 ) than control group participants ( n = 58 ) . In dose response models , greater participation in aerobic exercise was associated with 11 % less fatigue ( p < .001 ) , 7.5 % more vigor ( p = .001 ) , and 3 % less emotional distress ( p = .03 ) , after controlling for intervention group assignment , age , and baseline exercise and fatigue levels . Conclusion . Patients who exercised during cancer treatment experienced less emotional distress than those who were less active . Increasing exercise was also associated with less fatigue and more vigor .  Home-based walking is a simple , sustainable strategy that may be helpful in improving a number of symptoms encountered by patients undergoing active treatment for cancer
