Book excerpt: The Routledge Handbook of Sport, Gender and Sexuality brings together important new work from 68 leading international scholars that, collectively, demonstrates the intrinsic interconnectedness of sport, gender and sexuality. It introduces what is, in essence, a sophisticated sub-area of sport sociology, covering the field comprehensively, as well as signalling ideas for future research and analysis. Wide-ranging across different historical periods, different sports, and different local and global contexts, the book incorporates personal, ideological and political narratives; varied conceptual, methodological and theoretical approaches; and examples of complexities and nuanced ways of understanding the gendered and sexualized dynamics of sport. It examines structural and cultural forms of gender segregation, homophobia, heteronormativity and transphobia, as well as the ideological struggles and changes that have led to nuanced ways of thinking about the sport, gender and sexuality nexus. This is a landmark work of reference that will be a key resource for students and researchers working in sport studies, gender studies, sexuality studies or sociology.
