| Summary: | The aim of the present study was to analyze the number and the % of maximum accelerations, and the distance covered among differentsoccer players’ positions, classifying them with GPS technology according to an individual threshold based on the maximum acceleration capacity. 20players were observed during four matches (n=80). All players undertook a maximal running speed test to determine the maximal acceleration. Players’activities during the matches were classified into four individual acceleration thresholds: acceleration starting from 0 to 13 km·h-1 and never reaching18 km·h-1 (A1); acceleration starting from 0 to 13 km·h-1 and reaching 18 km·h-1 (A2); acceleration starting from 13 to 18 km·h-1 (A3); andacceleration starting above 18 km·h-1 (A4). During A1, Full-Backs performed a higher number of accelerations compared to other playing positionsand reached a ~95% of the maximum acceleration. During A2, Full-Backs and Wide Midfielder performed a higher number of accelerations thanCentral Defenders and Forwards, and Central Midfielders reached an estimated intensity of 95% of the maximum acceleration. During A3, CMperformed the highest number of accelerations compared to the rest of the groups, while F reached an estimated intensity of 78% of their maximumacceleration. This individualized threshold could help coaches assess players’ physical performance and improve it, or to avoid injuries. |
