Contextual factors and match-physical performance of international-level footballers with cerebral palsy

ABSTRACT

This study aimed to explore the match-physical response of international-level footballers with cerebral palsy (CP) according to contextual factors such as team ranking, the quality level of opposition, and match outcome. Eighty-two male outfield footballers with CP from top-ranked teams (n = 26) and bottom-ranked teams (n = 56) took part in this study. The match-player response was recorded using global positioning devices considering the total distance, distance covered at different velocities and number of short-term actions. Players from top-ranked teams covered more distance at low intensities compared to players from bottom-ranked teams (p < 0.05; 0.45 < ES < 0.49). Higher sprint distance, moderate and high accelerations/decelerations were found in players from top-ranked teams playing against teams of similar levels (p < 0.05; 0.73_g< 0.86). When players from bottom-ranked teams played against teams of equivalent rank, more physical requirements were presented in total distance, running from medium to sprint intensities, and the number of short-term actions (p < 0.0.05; −0.55S < −0.89). Players from the top-ranking teams presented greater sprint demands in losing matches (p<0.05; dg=-1.01). Considering the bottom-ranking opposition, players presented more running demands in matches with losing results in moderate running, sprinting, and moderate-to-high deceleration (p < 0.05; −0.61 < d_g < −0.64). The match-physical response of players with CP varies according to the contextual factors studied. The results provide advice for coaches and classifiers to understand more comprehensively the competing demands in CP football. This knowledge could help practitioners to prepare competition matches and planning training load or post-match recovery strategies, but also for the observation assessments of the classification process in this team para-sport.
