ABSTRACT
In recent years much research regarding match performance and training has been conducted, and science has been incorporated to a greater extent, in the planning and execution of training. Changes in both performance and physiological response throughout a game have been studied. Another aspect that has drawn attention in practical training is information regarding individual differences in the physical demands to which players are exposed in games and training. These differences are related to the training status of the players and the specific tactical role of the player. Thus, some top-class clubs have integrated the tactical and physical demands of the players into their fitness training. A critical factor when training elite athletes is when to do what, i.e. to plan the training. An example of the preparation of the Danish national soccer team for the European Championship 2004 is given in the text. Thus, this review deals with the present knowledge of the demands of the game at a top-class level and provides insight into training and planning of training at an elite level. The chapter will mainly deal with male players, but at relevant places information about female players is given.
