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 menarche (AaM), with younger AaM corresponding to a faster maturational pace and older AaM a slower pace. Collegiate swimmers were significantly older at menarche (13.60 years ± 1.52 SD) than non-athletic controls (12.75 years ± 1.44 SD). In addition, the top-performing third of college swimmers in our sample were significantly older at menarche (14.06 years ± 1.59 SD) than the bottom-performing third (13.32 years ± 1.35 SD). We can conclude that (1) collegiate swimmers are older at menarche than controls and (2) swim performance is associated with later ages at menarche.
