Sport is one of the most popular leisure activities in the world. Why is this so? The leading thesis of the book is: Because sport regularly produces - mostly positively evaluated - situations of affective involvement. It is the felt-bodily experiences structurally inherent in sport to which sport owes its popularity. Robert Gugutzer substantiates this thesis by exploring a multitude of felt-bodily experiences of sport with the analytical means of the New Phenomenology (felt-body, situation, atmosphere). With the presented case analyses of various sports situations, -practices and -types, the book appears as the first and equally inventive introduction to neo-phenomenological sports research.
