This theoretical study on the sport exercises of virtual bodies (avatars) in virtual Fitness Clubs discusses the sense of being in the Virtual World (VW) in relation to virtual exercises and concepts on body ownership and presence. Based on interdisciplinary research and data, the purpose of this theoretical reflection is to contribute to the formulation of a more coherent theoretical model surrounding the issue of sport exercises and the virtual body. This matter emerges as a significant topic in the field of sport sociology and sport science in general and provides fertile ground for multiple analyses for future research.
