This book examines how sport and leisure have the capacity to impact our understanding and experience of culture, protest, and social change. The temporal dimensions of sport and leisure across different but interdependently connected sociopolitical lifeworlds demonstrate the ways in which popular cultural and subcultural forms intersect across temporal periods, which then force us to stretch and problematize the relationship between sport, leisure, and sociology. Bringing together chapters from experts on topics such as the modern Olympic studies, the sociology of English and US soccer, and feminist cultural studies, this collection presents new empirical and theoretical insights into the mobilizations and collective behaviours of sports athletes and fans on equal pay, environmental destruction, disability rights, safety and securitization, and anti-Olympic opposition. This collection seeks to address one of the most under-researched lifeworlds in the study of protest, activism, and social movements: the construction of relational collective identities in and through sport and leisure. Sport, Activism, and Social Movements is an essential text for scholars and students interested in sport and leisure, protest, social movements, and activism.
