This book offers the first critical examination of the contributions of feminist new materialist thought to the study of sport, fitness, and physical culture. Bringing feminist new materialist theory into a lively dialogue with sport studies, it highlights the possibilities and challenges of engaging with posthumanist and new materialist theories. With empirical examples and pedagogical offerings woven throughout, the book makes complex new materialist concepts and theories highly accessible. It vividly illustrates sporting matter as lively, vital, and agentic. Engaging specifically with the methodological, theoretical, ethical and political challenges of feminist new materialisms, it elaborates understandings of moving bodies and their entanglements with human, non-human, technological, biological, cultural, and environmental forces in contemporary society. This book extends humanist, representationalist, and discursive approaches that have characterized the landscape of critical research on active bodies, and invites new imaginings and articulations for sport and moving bodies in uncertain times and unknown futures.
