Effect of a fatigue task on absolute and relavitised indices of isokinetic leg strength in female collegiate soccer players

The evaluation of the offensive movements is usually qualitative: indeed, quantitative analyses of these movements, of the time necessary for their perfect repeatability, and of the players' ability to follow them have never been performed. A simplified model was used with only eight offensive players and without defensive players, and a single frame of the action that could characterize the final result of the attack, a goal, was selected. The variability of the reciprocal positions of the eight football players in this single moment of the offensive scheme was assessed using bivariate analysis. The coordinates of each player were analyzed by bivariate analysis, separately for the two teams and for the two schemes. Bivariate analysis was used because it provides a more integrated and statistically correct evaluation of positions where the horizontal and vertical coordinates depend on each other. The presence of opponents would have modified the same offensive schemes: further investigations should analyze the repeatability of more complex schemes.
