'That time of the month' … for the biggest event of your career! Perception of menstrual cycle on performance of Australian athletes training for the 2020 Olympic and Paralympic Games.

OBJECTIVE

This study explored the perceived effect of the menstrual cycle (MC) on the performance of Australian female athletes, preparing for the Tokyo Olympic and/or Paralympic Games.

METHODS

195 female athletes, nominated by 24 National Sporting Organisations as preparing for the Tokyo Olympic and/or Paralympic Games, completed an online questionnaire ('MCq perceptions'). The MCq perceptions investigated menstrual symptoms, hormonal contraceptive (HC) use and a preferred competition window within the MC.

RESULTS

Two-thirds (65.6%) athletes reported that their MC affected their performance; in training (65.6%) compared with competition (58.0%).Aesthetic-sport athletes were most likely to perceive their performance to be affected by their MC (RR=1.40) compared with endurance (RR=0.88) and strength-sport (RR=1.04) athletes. Athletes experiencing three or more symptoms were twice as likely to identify as affected. Athletes who reported pain (RR=1.89) or the use of analgesia (RR=1.45) were more likely to identify as affected by their MC.A preferred competition window was identified by athletes as 'just after your period' (41.5%). For athletes not using HC, this window was identified by 53.7%.

CONCLUSION

In Australia, elite-female athletes perceive their MC to affect their performance, and many have a preferred performance window. Performance-focused strategies should be created for 'affected' athletes, aiming to provide these athletes with education, and where appropriate, control over predictability, timing and symptoms of their MC.
