The purpose of this study was to examine the influence of ovulation (OV) on dynamic balance in young female. Thirty-two eumenorrheic healthy women participated in Biodex Balance System (BBS) test for postural stability and a limit of stability menstrual cycle. BBS was tested in the menses (MS), OV, and luteal phase (LP). The limits of stabilities (total, forward-left, forward-right, backward-left, and backward-right) were significantly higher in the OV (total, 61.44±14.77; forward-left, 67.50± 15.17; forward-right, 69.50±14.43; backward-left, 64.00±20.32; and back-ward-right, 69.06±13.59) than in the MS (total, 55.44±14.63; forward-left, 60.00±15.98; forward-right, 62.17±9.78; backward-left, 57.83±19.09; and backward-right, 57.28±13.73). Furthermore, the LP (65.11±13.79) was a significantly higher limit of stability than MS (57.28±13.73) during back-ward-right. The present study showed that estrogen negatively influ-ences postural stability. The postural sway in limits of stabilities (total, forward-left, forward-right, backward-left, and backward-right) were significantly the greatest in the OV. Since there is a different postural stability between MS, OV, and LP, this should be taken into account when devising training programs to avoid risk factor of fall and joint injury.
