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 .
What level of physical activity protects against premature cardiovascular death? The Caerphilly study
Objective : To examine the optimal intensity of leisure time physical activity ( LTPA ) to decrease the risk of all cause , cardiovascular disease ( CVD ) , and coronary heart disease ( CHD ) mortality in a population sample of middle aged British men . Design : Prospect i ve study of middle aged men with an 11 year follow up . Setting : A whole population sample of men from Caerphilly , South Wales , UK . Subjects : 1975 men aged 49–64 years without historical or clinical evidence of CHD at baseline examination . Main outcome measures : All cause , CVD , and CHD mortality . Results : Total ( cumulative ) LTPA had a grade d , significant relation with all cause , CVD , and CHD mortality but no trend with cancer deaths . When different intensities of activity were considered , light and moderate intensity LTPA had inconsistent and non-significant relations with all cause , CVD , or CHD mortality whether adjusted only for age or for other cardiovascular risk factors . In contrast a significant dose – response relation was found for heavy intensity LTPA for all cause , CVD , and CHD mortality fully adjusted for other risk factors . Conclusions : These data suggest that , in a population of men without evidence of CHD at baseline , only leisure exercise classified as heavy or vigorous was independently associated with reduced risk of premature death from CVD
