Performance Profiles: A New Approach Based on Training Focused on Physical Aspects Rather than Technical-Tactical Ones.

This study aimed to identify distinct external load profiles of 23 semi-professional football players (22.52 ± 1.74 years) during four official matches (40 cases in total; 10 per match). Using GPS-based inertial technology WIMU PRO (Hudl, Lincoln, NE, USA), data were collected to analyze players' physical performance. A principal component analysis (PCA) identified three performance profiles-"Total Player," "Explosive Player," and "Dynamic Player"-that together explained 70.08% of the variance. These profiles revealed that players may share similar physical characteristics despite occupying different on-field positions. Training players based on their physical performance profiles, rather than solely on their tactical roles, may enhance both individual development and overall team performance. This approach offers a novel framework for individualized conditioning in team sports.
