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 .
Results of a 10 week community based strength and balance training programme to reduce fall risk factors: a randomised controlled trial in 65–75 year old women with osteoporosis
Objective —To test the efficacy of a community based 10 week exercise intervention to reduce fall risk factors in women with osteoporosis . Methods —Static balance was measured by computerised dynamic posturography ( Equitest ) , dynamic balance by timed figure of eight run , and knee extension strength by dynamometry . Subjects were r and omised to exercise intervention ( twice weekly Osteofit classes for 10 weeks ) or control groups . Results —The outcome in 79 participants ( 39 exercise , 40 control ) who were available for measurement 10 weeks after baseline measurement is reported . After confounding factors had been controlled for , the exercise group did not make significant gains compared with their control counterparts , although there were consistent trends toward greater improvement in all three primary outcome measures . Relative to the change in control subjects , the exercise group improved by 2.3 % in static balance , 1.9 % in dynamic balance , and 13.9 % in knee extension strength . Conclusions —A 10 week community based physical activity intervention did not significantly reduce fall risk factors in women with osteoporosis . However , trends toward improvement in key independent risk factors for falling suggest that a study with greater power may show that these variables can be improved to a level that reaches statistical significance
