To investigate the relationship between age at beginning of training, onset of menarche, distance for training of running, and lumbar bone mineral density (LBMD), twenty-six female long distance runners aged 18years old and above were examined. Runners suspected primary amenorrhea were excluded in this study.Runners who started training before menarche were delayed their onset of menarche significantly. The age at onset of menarche was selected as determining factor for LBMD, and was significantly negatively correlated to LBMD. It should be important not to delay menarche for preventing low LBMD in female long distance runners.
