Lean mass and biological maturation as predictors of muscle power and strength performance in young athletes.
<h4>Background</h4>The biological maturation (BM) analyzed by peak height velocity (PHV) and bone age (BA), and lean body mass has been associated with the strength and muscle power of young athletes. However, the ability of BM (PHV and BA) and LM markers to predict muscle strength and p...
