Abstract

This study investigated variability in competitive high-speed running performance in an elite soccer team. A semi-automated tracking system quantified running performance in 12 players over a season (median 17 matches per player, 207 observations). Variability (coefficient of variation [CV]) was compared for: total sprint distance (TSD, >25.2 km/h), high-speed running (HSR, 19.8-25.2 km/h), total high-speed running (THSR, ≥19.8 km/h); THSR when the team was in and out of ball possession, in individual ball possession, in the peak 5-min activity period; and distance run according to individual maximal aerobic speed (MAS). Variability for % declines in THSR and distance covered at ≥80% MAS across halves, at the end of play (final 15-min versus mean for all 15-min periods), and transiently (5-min period following peak 5-min activity period) was analysed. Collectively, variability was higher for TSD versus HSR and THSR and lowest for distance run at ≥80% MAS (CVs: 37.1%, 18.1%, 19.8% and 11.8%). THSR CVs when the team was in/out of ball possession, in individual ball possession and during the peak 5-min period were 31.5%, 26.1%, 60.1% and 23.9%. Variability in THSR declines across halves, at the end of play and transiently, ranged from 37.1%-142.6%, while lower CVs were observed in these metrics for running at ≥80% MAS (20.9%-53.3%).These results cast doubt on the appropriateness of general measures of high-speed activity for determining variability in an elite soccer team although individualisation of high-speed running thresholds according to fitness characteristics might provide more stable indicators of running performance and fatigue occurrence.
