Differences by field positions between young and senior amateur soccer players using GPS technologies

Aim. The aim of this study was to examine the player performance model (PPM) of soccer by field position, between under 20 amateur players and over 20 amateur players, with the using of GPS (K-Sport Universal, Italy). Methods. The performance parameters data collection has been possible with GPS (Global Position System). In our case were analysed 6 matches in First Category championship (Marche, Italy), corresponding at the seventh level of Italian league and 6 games of the Juniors Provincial championship (Marche, Italy), using 10 GPS (20 Hz, K-Sport International, Montelabbate, Italy), 5 for each team, each divided into positions, to give larger specificity to the study. Afterward data were analysed. Results. The analysis of the data, shows that, the under 20 travelled more distance in high intensity during a game, than over 20. But the over 20 travelled higher total distance, probably this data is influenced by the average of minutes played, that is lower in the over 20 because they effectuated more substitutions during the detected games. Conclusions. It is being understood that technical and tactical qualities are the most important values for a football player, anyway during the last years the physical performance became crucial to determinate the result of a game. The detection of PPM helps to increase the quality of the training schedule, furthermore differentiate the PPM even for category and field position, can make more specific and accurate the work of the coaches and fitness trainer.
