The assumption in delayed menarche was that menarche is delayed in females who train regularly before and after onset due to excessive physical and mental stress. However, methodological problems involved with producing a precise explanation for delayed menarche have not yet been solved. Even when menarche is indeed delayed, the influence of sports training cannot be confirmed. Fujii verified delayed menarche in female athletes by examining the interval between age at the maximum peak velocity of height (MPV), a measure of maximum growth velocity during adolescence and age at menarche derived from the wavelet interpolation method (WIM). Based on the above finding, level of body stature was also classified from height in this study, with the second year of high school as the reference, against the constructed evaluation chart. Girls were classified by height as tall, average, or short, and an attempt was made to evaluate delayed menarche by height classification. Thus, risk analysis of delayed menarche in Koreans girls was done by applying the delayed menarche evaluation system for tall-short type.
