Maturational pace and performance in female collegiate swimmers
<p>purpose of this research was (1) to compare maturational pace between the female collegiate swimmers and non-athletic controls and (2) to determine whether maturational pace differs as a function of performance level. Maturational pace can be quantified retrospectively in women using age at …
