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 .
Walking to Work Is an Independent Predictor of Incidence of Type 2 Diabetes in Japanese Men
Previous epidemiological studies have shown that vigorous physical activity reduces the development of type 2 diabetes ( 1–3 ) . A recommendation from the Centers for Disease Control and Prevention reported that individuals should engage in ≥30 min of moderate-intensity physical activity , such as brisk walking , on most days of the week for health promotion and disease prevention ( 4 ) ; however , it is unclear whether mild physical activity ( i.e. , walking to walk ) reduces the risk for type 2 diabetes . In the present study , we examined the relationship between walking to work  and the development of type 2 diabetes during a 4-year observational period . The Kansai Healthcare Study is an ongoing cohort investigation design ed to clarify the risk factors for cardiometabolic diseases . Between April 2000 and March 2001 , 12,647 male employees of a company in the area of Kansai , Japan , who were aged 40–55 years at entry and considered to be involved in sedentary jobs were enrolled in this study . All employees aged ≥40 years underwent annual detailed medical check-ups . The protocol for this research was review ed by the Human Subjects Review Committee at Osaka City University . For current analysis , study participants consisted of 11,073 Japanese men aged 40–55 years at entry with a fasting plasma glucose ( FPG ) < 126 mg/dl and not taking oral hypoglycemic medication or insulin . A 4-year follow-up examination after baseline was conducted between April 2004 and March 2005 . We excluded 53 men because of death and 2,016 men because of
