Key result
Objectively measured light and moderate-to-vigorous physical activity were associated with small artery compliance, explaining an additional 5.8% (P=0.003) and 2.7% (P=0.043) of variance, respectively.

Does objectively measured physical activity improve arterial compliance in children aged 8-11 years?
Effect estimate: 5.8% (light activity) and 2.7% (MVPA) additional variance in small artery compliance
p-value: p=0.003 (light activity), 0.043 (MVPA)
Objectively measured physical activity, including light and moderate-to-vigorous activity, is positively associated with small artery compliance in children aged 8-11 years.
Nettlefold et al. (2012) conducted a cross-sectional in Healthy children (n=102). Physical activity and sedentary time was evaluated on Large and small artery compliance (5.8% (light activity) and 2.7% (MVPA) additional variance in small artery compliance, p=0.003 (light activity), 0.043 (MVPA)). Objectively measured light and moderate-to-vigorous physical activity were associated with small artery compliance, explaining an additional 5.8% (P=0.003) and 2.7% (P=0.043) of variance, respectively.
