Abstract:
Soccer match analysis was initially establish by coach to evaluate tactical aspects, after this approach was used for physical effort. Previously this assessment has been done by video interpretation of the matches. The aim of this study was to analyze the official matches in adults athletes for the first time with a wearable device as GPS. Five official games of sixth division of Italian Football League were assessed with GPS system. Parameters represented the volume of physical activity as Total Distance covered and Relative Distance derived directly from the instrument, while the values of intensity as speed, acceleration and deceleration have been indexed respect to the maximum individual of each athletes. Was also made a tactical analysis respect the roles of players. Values of volume shows lower values than previous studies, while the values of intensity confirm the data present in the literature. Tactical analysis shows predominantly low speed for defenders, medium for midfiel
ders and high speed for forward. Acceleration not differ significantly between the roles. Decelerations are predominantly for midfielders. These are the preliminary results of a larger study involved for the first time soccer official matches assessed with a wearable system. In addition a new approach has been used in order to individualized threshold for speed, acceleration and deceleration.
