Abstract
Previous our research showed that cancer survivors have significantly lower QOL than do healthy subjects. Furthermore, the muscle strength of cancer survivors was positively related to QOL, while muscle strength was negatively related to QOL in healthy subjects. This our result indicates that muscle strength is an important factor to improve QOL in cancer survivors. Recently, some study investigated the effect of physical exercise on mortality in cancer patients. Actually, our previous review showed the rate of mortality among patients with higher physical activity, pre- and post-diagnosis, was lower that the mortality rate among sedentary patients, for breast, colorectal, colon, prostate, lung, endometrial, and ovarian cancer. Mortality was further decreased by physical activity of vigorous intensity.
