This week on the Fired Up Sport podcast, in association with Sport England and This Girl Can, Clare Mcdonnell and Kirsten Webster ask why is there still such a stigma around female athletes and periods? The monthly cycle has a fundamental impact on performance, so why is there so little research into its effects? Clare and Kirsten hear from Commonwealth Games medal winner long jumper Jazmin Sawyers, who took the unusual step of being honest about why she had to pull out of an event, she was in agony because of her period. They also hear from Australian Tennis star Priscilla Hon on how she never used to feel comfortable talking about her period to male coaches, but she does now. Plus Emma Ross, Head of Physiology at the English Institute of Sport, discusses the pioneering research she is doing which aims to help female athletes turn their period into a super power in time for the Tokyo Olympics in 2020. It's the Fired Up Sport podcast in association with Sport England and This Girl Can. Come with us and #ChangeTheConversation.
