Associations of fitness, motor competence, and adiposity with the indicators of physical activity intensity during different physical activities in children

Abstract We investigated the associations of peak oxygen uptake (V̇O2peak), ventilatory threshold (VT), muscle strength, motor competence (MC), and adiposity with the indicators of PA intensity during different physical activities used to create absolute PA intensity cut-offs among 35 children 7–11-...
