This research paper examines the contentious issue of transgender athletes' inclusion in collegiate sports, with a focus on Lia Thomas, a University of Pennsylvania swimmer. The study addresses the lack of understanding and consensus on this topic by investigating biological differences and social justice implications. The abstract highlights the controversy surrounding Thomas's success and legislative restrictions in 23 states since 2020. It argues for a balanced approach, considering both biological advantages and the need for social justice, emphasizing discrimination faced by transgender athletes and the importance of fair competition. Research methods involve an observational approach, analyzing existing data and conducting a needs assessment research inquiry to improve regulations. The goal is to gather reliable data on transgender female athletes' performance before and after transitioning, using descriptive statistics for analysis, contributing to creating more informed and equitable guidelines for their inclusion in the sports community.
