Periods in Play: Sports and Menstruation

The webinar "Periods in Play" brought together global experts to examine how menstruation intersects with adolescent sport participation. Organizers highlighted a new free MOOC, a puberty education book, and a scoping review that synthesized 86 studies from 33 countries, revealing that menstrual experiences are a largely overlooked factor in the well‑documented decline in girls’ physical activity during puberty. Key findings showed that menstrual symptoms—cramps, fatigue, and fear of leakage—act as barriers, while the same activity can also mitigate those symptoms for many participants. Knowledge interventions proved powerful: girls who read the puberty book were eight times more likely to recognize exercise as safe and three times more likely to shift toward positive beliefs about training during their periods. The review also exposed methodological gaps, such as inconsistent measurement of both menstruation and activity, and a scarcity of longitudinal, culturally diverse data. A striking quote from an Olympic swimmer in Japan underscored the cultural silence: "We all thought it was normal and didn’t know you could deal with these symptoms…" Speakers from the UK, Canada, Zambia, and the Netherlands reinforced the need for open dialogue, flexible uniform policies, and free access to menstrual products in schools and sport settings. The implications are clear: policymakers must embed menstrual health into public‑health and sport‑development strategies, schools should create stigma‑free environments, and researchers need standardized, device‑based metrics to capture the bi‑directional relationship. Addressing these gaps could keep millions of adolescent girls active, improve health outcomes, and broaden the talent pool for elite sport.
