Key result
Sedentary time was significantly associated with increased arterial stiffness (AIx r=0.38, P<0.001), whereas moderate-to-vigorous physical activity was inversely correlated with AIx (r=-0.28, P<0.05).

Does physical activity improve arterial stiffness and adiposity in healthy middle-aged subjects?
Effect estimate: r = 0.38
p-value: p=< .001
Increased sedentary time is associated with greater arterial stiffness and body fat, whereas higher moderate-to-vigorous physical activity correlates with reduced arterial stiffness in healthy middle-aged individuals.
Ananey et al. (2015) conducted a cross-sectional in Healthy (n=79). Sedentary time and physical activity was evaluated on Arterial stiffness (augmentation index [AIx] and pulse wave velocity [PWV]) (r = 0.38, p=< .001). Sedentary time was significantly associated with increased arterial stiffness (AIx r=0.38, P<0.001), whereas moderate-to-vigorous physical activity was inversely correlated with AIx (r=-0.28, P<0.05).
