Abstract
Sometimes a need to define something simple as sport seems unnecessary, especially because everyone, or at least great number of us has sometimes in some part of our lives came in contact with sport, no matter whether that activity came through physical education, organized sport club, or just through simple game with your friends in your old street, neighborhood, or backyard. Well, there is not easy way to put it, but that is to some extent wrong standpoint. Like some other branches sport has evolved, a lot actually from its beginnings, especially in last three decades, and now like in any other industry there is a need for theoretical explanation of all that what follows the game itself, a science that will support practice.
Good explanation of sport and its core is coming from professor Loy (1968) who explained that sport has to have five different universal characteristics to be even considered as sport, those characteristics are following: sport has to be play like in nature, it has to involve some kind of competition, also another characteristics says that it needs to be based on physical prowess, sport has to involve some elements that include chance, strategy and skill, and finally to have unknown outcome (Loy, 1968).
