Philosophy of sport

What exactly does the phrase, "the philosophy of sport" mean? The two words are not usually associated, with sports concerning subject matter much less complicated than the world of philosophy. For me, the philosophy of sport refers to all the aspects of sports around the world that people have come to love, whether it be the hard work required to suceed when laying a sport, the dedication and the mental strain required to sucessfully coach a sport, and the unexplainable feelings of the commited fan to their team. The Philosophy of sport embodies the entire realm that is sports in our world today.
