Sedentary behavior: the new physical activity frontier? by Paul Gardiner, PhD
It’s a given that participation in moderate-to vigorous-intensity physical activity (MVPA) can minimize some of the physiologic changes associated with aging, and alter the progression and development of chronic disease and disabling conditions.

Recent evidence underlines the importance of also focusing on sedentary behaviors—the high amount of time that people spend sitting during their “non-exercising” waking hours (1, 2).
