How to Track Your Menstrual Cycle

by Dr Stacy Sims
Oct 14, 2024

Take your performance to the next level by understanding your unique physiology.

In the summer of 2019, the U.S. Women’s National Team (USWNT) won the World Cup, making it the U.S. women’s fourth World Cup title. They scored a record-setting 26 goals throughout the tournament and also made history with their training tactics: For the first time in the teams World Cup history, USWNT coaches tracked players’ menstrual cycles and symptoms, and adjusted the players training to help them perform their best.

Dawn Scott, high-performance coach for both the USWNT and the National Women's Soccer League, credited the breakthrough use of period tracking as one of the strategies the team used to take their performance to the next level. "I feel like it's one of many strategies that we deployed that helped us win," Scott told Good Morning America. "We could see what [menstrual cycle] phase a player was in and what some of their symptoms were," Scott said. "I would just text or say to a player, 'Hey you're in phase three and we know you get disrupted sleep, so make sure you do x, y and z.'"

While it’s always hard being away from my family for this long, this is also the time where I get to see and feel the impact of female science and research in action. It ha...
