Grade B evidence also suggested that exercise may improve prostate cancer patients ' muscle mass , muscular strength , functional performance ( walking and sit to st and speed ) , as well as health-related , social and physical quality of life .
These effects appeared greater for group-rather than home-based-exercise , especially if these programs included resistance training .
CONTEXT Prostate cancer patients , especially those on and rogen deprivation therapy ( ADT ) , experience many symptoms that make it difficult to maintain their independence and quality of life .
Because ADT acts by means of reducing testosterone production , exercise may offset many of the ADT side effects and those of the cancer itself .

A prospective study of physical activity and incident and fatal prostate cancer.
BACKGROUND Whether physical activity has benefits against prostate cancer incidence or progression is unclear . Therefore , we assessed physical activity in relation to prostate cancer incidence , mortality , and Gleason histologic grade . METHODS We used data from the Health Professionals Follow-up Study , a prospect i ve cohort study , to determine the number of cases of incident , advanced ( seminal vesicle invasion , metastasis , or fatal ) , fatal , and high- grade prostate cancer in a cohort of 47,620 US male health professionals , followed up from February 1 , 1986 , to January 31 , 2000 . RESULTS During 14 years of follow-up , we documented 2892 new cases of prostate cancer , including 482 advanced cases ( 280 of which were fatal ) . For total prostate cancer , no association was observed for total , vigorous , and nonvigorous physical activity . In men 65 years or older , we observed a lower risk in the highest category of  vigorous activity  for advanced ( multivariable relative risk , 0.33 ; 95 % confidence interval , 0.17 - 0.62 , for more than 29 vs 0 metabolic equivalent hours ) and for fatal ( relative risk , 0.26 ; 95 % confidence interval , 0.11 - 0.66 ) prostate cancer . No associations were observed in younger men . Differential screening by  prostate-specific antigen  or a reduction in physical activity  due to undiagnosed prostate cancer did not appear to account for the results . Among cases , men with high levels of physical activity were less likely to be diagnosed with poorly differentiated cancers ( Gleason grade > or = 7 ) . CONCLUSION Although the mechanisms are not yet understood , these findings suggest that regular vigorous activity could slow the progression of prostate cancer and might be recommended to reduce mortality from prostate cancer , particularly given the many other documented benefits of exercise
