Estimations of the incubation durations to overt clinical conditions for diseases/conditions caused by physical inactivity and of the percentage reductions in diseases primarily prevented by physical activity (where sufficient information exists in healthy humans aged 20–65 yrs of age).

Disease/condition Inactivity causes (Longer-term most days of the week implies years or decades while short-term is weeks to months) Exercise primarily prevents\delays
* Just meet guidelines for moderate activity (30 min/day), not intent-treat.
** Our speculated asymptote for maximum in dose-response
