Effects of substituting sedentary time with physical activity on metabolic risk.

ABSTRACT:

Purpose

The detrimental effects of sedentary time on health may act by replacing time spent in physical activities. The aim of this study was to examine cross-sectional associations between objectively assessed sedentary and physical activity domains and cardiometabolic risk factors using a novel isotemporal substitution paradigm.

Methods

Participants were 445 healthy men and women (mean age, 66 ± 6 yr), without history or objective signs of cardiovascular disease, drawn from the Whitehall II epidemiological cohort. Physical activity was objectively measured using accelerometers (ActiGraph GT3X) worn around the waist during waking hours for 4-7 consecutive days. We examined the effects of replacing sedentary time with light activity or moderate-to-vigorous physical activity
