To investigate the effects of exercise on the onset of menses in premenarchal girls.
To examine the influence of strenuous exercise on menstrual patterns in postmenarchal women.

Main Methods:

Observational analysis of training effects on puberty onset.
Review of menstrual cycle alterations in response to varying exercise intensities.

Main Results:

Premenarchal training may delay menarche onset without adverse developmental effects.

Conclusions:

Exercise can influence the timing of puberty and menstrual regularity in women.
Factors like body fat, stress, and energy balance modulate exercise's impact on menstruation.
Reversible menstrual changes suggest adaptation to training stress.
