The purpose of this study was to determine the effect of hormonal changes according to menstrual cycle on balance and mood in non-athletic female subjects. Twenty non-athletic women with regular menstrual cycles participated in this study. Balance ability was evaluated as static balance and dynamic balance. Static balance was measured using the distance and average velocity of the center of pressure (CoP). Distance indicated the path length for the duration of the trial and average velocity was the path length covered per unit of time. Dynamic balance was measured using the distance of the Y-balance test. Mood was assessed using the Profile of Mood States (POMS). All tests were conducted during a full cycle of menstruation and ovulation. During ovulation, path length and average velocity of CoP decreased significantly (p<.05). Anterior distance of the Y-balance test significantly increased during ovulation (p<.05). Posteromedial and posterolateral distances were not significantly different between the menstrual and ovulatory periods (p>.05). In terms of mood, “Anger” and the total POMS score significantly decreased during ovulation (p<.05). These results suggest that non-athletic women should be aware of the physical and psychological changes during each menstrual cycle in order to prevent the increased risk of injury.
