Female sport participation is increasing globally and in recent years, there has been growing recognition of the need to better understand the specific health, developmental, and performance considerations of female athletes across the life span. Despite this progress, dropout rates from female sports, especially during adolescence, is observed worldwide.  One in five girls drops out of sport between primary school and post-primary school, compared to just one in twenty boys of the same age. The drop in participation among girls often coincides with adolescence, a key stage of growth and development that brings physical, psychological and social changes that can shape their sporting experiences. To help understand how sport systems can better meet the needs of girls, this research aimed to explore the experiences of youth female athletes across organised sport in Ireland.
