Diverse sex, gender, and sexual identities historically have been pushed to the margins in sport. While there is more visibility and inclusion for LGBTIQ (lesbian, gay, bisexual, transgender, intersex, queer) people in sport today than in the past, there still exists bigotry and marginalization. In this book, Vikki Krane and a team of leading sport scholars critically assess what we know about sex, gender, and sexuality in sport; expose areas in need of further inquiry; and offer new avenues for theory, research, and practice. Drawing on cultural studies perspectives, and with social justice at the heart of every chapter, the book discusses theory, policy, practice, and the experiences of LGBTIQ people in sport (removed around the world).
