In this special edition of the Innovation Series, host Lucy Mills talks with Dr Sarah Zipp, a globally recognized researcher on sport, gender, and menstrual health, to explore an often-overlooked challenge: the impact of puberty and menstrual health on adolescent girls in sport. Dr Zipp, founder of Power to Play Period, has dedicated her work to addressing the bio-social barriers that lead to girls dropping out of sports at twice the rate of boys during adolescence. She is pioneering innovative solutions to issues such as the stigma around menstruation, body confidence, gender norms, lack of female coaches, and the need for supportive environments in sport. Join us to gain insights into the multifaceted reasons behind adolescent girls’ reduced participation in sport, with a focus on physical changes during puberty, societal stigmas, and the cultural silence around menstrual health. And learn more about Dr Zipp’s pioneering work on empowering coaches, families, and communities via education and programs, as well as collaborations with federations, schools, NGOs, and brands. **About Dr Sarah Zipp:** Dr Sarah Zipp is a leading researcher on sport, gender and menstrual health.
