On International Women’s Day, we’re reminded of the importance of undertaking women-specific research within the sport sector. Recent research on the relationship between women’s health and soccer showed that muscle and tendon injury rates were 88% higher during specific phases of the menstrual cycle. Additionally, 20% of injuries occurred after the expected date of menstruation. These findings demonstrate that monitoring and identifying extended menstrual cycles can improve the health of athletes and reduce injury incidence.
