Longitudinal changing relationships between growth tempo and vertical stiffness in movement across maturation

To determine whether average growth tempo influenced longitudinal relationships between maturity status and coordination capability using a 15-s hopping task (Aim 1). To investigate how differences in absolute growth tempo were associated with change in coordination capability within and across peak growth (Aim 2).Participants were NFor Aim 1, log-linear mixed model trends identified maturity status and growth tempo were significantly associated with KWithin maturational progression, short-term accelerations in growth tempo corresponded with short-term decreases in K
