Abstract
Purpose: The aims of this study were to examine the variability of selected external load metrics within 15-min intervals during soccer match play and examine their relationship with players’ high-intensity intermittent fitness. Methods: A total of 18 male soccer players were monitored for their external load metrics during 26 matches which included: total distance (TD), high metabolic load distance (HMLD), and mechanical work (MW) (defined as the sum of accelerations and decelerations >3 m2). Additionally, players completed the 30-15 Intermittent Fitness Test (VIFT). Results: TD had lower coefficient of variation (CV) values than HMLD and MW (ES; 5.2 to 6.4; very large). Within-players’ ∆-15min showed moderate-to-large decreases (ES; -0.7 to -1.6) and increases (ES; 0.9 to 1.8) in absolute and CV values, respectively. Large relationships (r= 0.55 to 0.61) were observed between VIFT and 15-minmean and 15-minbest in all selected external load metrics. However, small-to-moderate (0.27 to 0.41) associations were observed between VIFT and ∆-15min in selected external load metrics. Conclusion: These findings suggest that those players with relatively lower intermittent running capacity might show lower variability during the match, as evidenced by smaller reductions in high intensity actions during the final 15 minutes. We attribute these observations to players’ possessing better pacing strategies.
