  1. \( \dot{\mathrm{V}}{\mathrm{O}}_{2\mathrm{peak}} \) maximal volume of oxygen consumed over 30-sec during the aerobic fitness test, W peak peak workload achieved during the aerobic fitness test, MVPA moderate-to-vigorous physical activity. Mean difference calculated as JIA – control. Statistical significance set at p ≤ 0.05
