There is evidence that exercise , such as low intensity aerobics walking , Tai Chi , or cycling , results in an overall decrease in fatigue levels over the course of cancer treatment .
Additionally , there is evidence that regular physical activity or exercise can decrease emotional stress , blood pressure , the duration of neutropenia , thrombocytopenia , and pain .
Exercise also has been shown to increase quality of life and improve the maximal oxygen uptake during exertion , sleep patterns , and cognition .
Disease and cancer treatment-related side effects such as decreased energy level , muscle weakness , and declines in functional status and body mass have been well documented .
However , the majority of studies of exercise and cancer have been conducted with women with early stage breast cancer , limiting the generalizability of these studies to other cancer population s. The purpose of this systematic review is to provide a synthesis of the extant research evidence about th e benefits of exercise related to cancer recovery
Effects of physical activity on the fatigue and psychologic status of cancer patients during chemotherapy
Fatigue is a common and often severe problem in cancer patients undergoing chemotherapy .  The authors postulated that physical activity training can reduce the intensity of fatigue in this group of patients
