ABSTRACT
An ergonomics model of training signifies that the programme is designed to prepare the individual for the demands of the game. The capabilities of the individual are thereby raised and an enhancement of performance is anticipated. This process is not a singular event but takes place within a highly dynamic and complex soccer context. It is important to know if the training intervention has been effective and whether all players engaged in it have benefited equally. Besides, new players may be entering a team squad, and others returning after a period of injury so it is necessary to establish how their fitness levels differ from the rest of the team.
