Regular physical activity exhibits a strong inverse and linear dose-response relationship with all-cause mortality, cardiovascular disease incidence, and type 2 diabetes mellitus incidence, where greater activity volume yields greater health benefits.
To significantly lower your risk of death, heart disease, and type 2 diabetes, aim for at least 1000 kcal of energy expenditure per week through physical activity. Even half that amount (500 kcal/week) offers some protection. Consistency matters more than intensity for these specific outcomes.
There is a strong suggestion of an inverse and linear relationship between regular physical activity and rates of all-cause mortality, total cardiovascular disease, coronary heart disease incidence and mortality, and incidence of type 2 diabetes mellitus.
Why this rating
Based on Category C evidence (observational studies) with a large body of data (44 studies for mortality), though RCTs for mortality are not feasible.
