Abstract
This study explored physical match demands across different playing positions during transitional play, to inform the need for position-specific training interventions. Data was collected using 10 Hz GPS units from 10 competitive matches including 23 elite soccer players of the 1(st) Polish Division (Ekstraklasa) in season 2020-21. A total of 4249 positional observations were made; center backs (n = 884), full backs (n = 972), central defensive midfielders (n = 236), central attacking midfielders (n = 270), central midfielders (n = 578), wingers (n = 778), and attackers (n = 531). Match data reflected distances covered per minute (m · min(-1)): total distance (TD), high-speed running distance (HSRD, > 19.8 km · h(-1)), sprint distance (SD, > 25.2 km · h(-1)), and the frequency of high-intensity accelerations and decelerations (A+D, > 3 m · s(-2); n · min(-1)). Total absolute sprint distance (SD, > 25.2 km · h(-1)) and total relative sprint distance (Rel B5) were also quantified. A univariate analysis of variance revealed position-specific differences. Significant effects of position were found for all analysed metrics during transitional play (large ESs; p <.001). Central attacking midfielders displayed higher TD (m · min(-1)), fullbacks covered highest SD (m · min(-1)) and wingers achieved the highest A+D (n · min(-1)) (p ≤ 0.05). Centre backs displayed the lowest physical outputs when compared to all other positions, except in A+D (n · min(-1)) during defensive transitions (p ≤ 0.05). Attackers displayed the highest physical metrics during high pressure activities (p ≤ 0.05). Coaches should carefully consider positional transitional demands to better inform training design. With specific attention paid to drills that replicate game play.
