Overall , the current literature supports clearly the dose-response relationship between physical activity and the seven chronic conditions identified .
Moreover , higher levels of physical activity reduce the risk for premature all-cause mortality .
The current Canadian guidelines appear to be appropriate to reduce the risk for the seven chronic conditions identified above and all-cause mortality
This systematic review examines critically the scientific basis for Canada 's Physical Activity Guide for Healthy Active Living for adults .
Particular reference is given to the dose-response relationship between physical activity and premature all-cause mortality and seven chronic diseases ( cardiovascular disease , stroke , hypertension , colon cancer , breast cancer , type 2 diabetes ( diabetes mellitus ) and osteoporosis ) .
The strength of the relationship between physical activity and specific health outcomes is evaluated critically .
Cardiorespiratory fitness and stroke mortality in men.
PURPOSE We examined the association between cardiorespiratory fitness and stroke mortality in men . METHODS This is a prospect i ve cohort study . We followed 16,878 men , ages 40 - 87 yr , who had a complete medical evaluation including a maximal treadmill exercise test and self-reported health habits .  There were 32 stroke deaths  during an average of 10 yr of follow-up ( 167,961 man-yr ) . RESULTS After adjustment for age and examination year , there was an inverse association between cardiorespiratory fitness and stroke mortality ( P = 0.005 for trend ) . This association remained after further adjustment for cigarette smoking , alcohol intake , body mass index , hypertension , diabetes mellitus , and parental history of coronary heart disease ( P = 0.02 for trend ) . High-fit men ( most fit 40 % ) had 68 % ( 95 % CI : 0.12 , 0.82 ) and moderate-fit men had 63 % ( 95 % CI : 0.17 , 0.83 ) lower risk of stroke mortality when compared with low-fit men ( least fit 20 % ) , respectively . CONCLUSIONS Moderate and high levels of cardiorespiratory fitness were associated with lower risk of stroke mortality in men in the Aerobics Center Longitudinal study population
