ABSTRACT
According to Farfel (1960) all sports disciplines may be divided into three groups depending on the levels of movement coordination. The most difficult disciplines require accurate and rapid movements under changing conditions. Football is one of these. Significant research attention has been given to the technical difficulty of this discipline and even more to development of physical fitness (Reilly and Thomas, 1977: Talaga, 1983, Reilly et al., 1988). However, little attention has been paid to the interdependence of efficiency and co-ordination or the effect of fatigue on the co-ordination level of soccer players. This is surprising, as the accuracy of movements during the whole match can decide the winner. The present study was undertaken to fill the existing gap. The purpose was to determine the changes taking place in co-ordination of players under variable physical loads.
