Abstract

The aim of the study is of going deeply into the knowledge of the behaviour of the HR of the professional football players into competition. For it the values that make up the behaviour of the HR of 6 professional football players have been gathered with different missions in the team, in the course of games of competition. The results derived from the analysis of this information seem to indicate that there exist significant differences between the different tactics positions, both in terms of values and percentiles and of marked increases, in the values that make up the behaviour of the HR of the players of the sample. These results might appear towards that the behaviour of the HR seems to be slightly directly linked to the recovered tactical position and/or to the physical and physiological profile of every football player.
