Abstract

The purpose of this study was to analyse the impact of an intermittent test reproducing the soccer running activity profile on physical performance, subjective ratings and biochemical parameters throughout 72 h recovery. 8 professional soccer players performed the intermittent test on a non-motorised treadmill and data was collected before, immediately after, 24, 48 and 72 h after the test. Squat jump (SJ), countermovement jump (CMJ), peak isometric force (IFpeak), 6-s sprint, repeated sprints test (RS), perceptual ratings (fatigue, muscle soreness, stress), creatine kinase ([CK]) and uric acid ([UA]) were analyzed. After the test, a mean reduction in countermovement jump performance of  − 8.2% (CI: − 12.9 to − 3.4, p<0.01) was observed, while perceived fatigue (+2.1±1.7 a.u.; p<0.05), perceived muscle soreness (+1.8±1.5 a.u.; p<0.05), perceived stress (+1.6±1.5 a.u.; p<0.05), creatine kinase (+171±77 IU.l − 1; p<0.01) and uric acid (+168±89 Umol.l − 1; p<0.01) concentrations were significantly increased relative to baseline. No significant effect was found for SJ, IFpeak, 6-s sprint, RS immediately after and throughout the 72 h following the test. In conclusion, soccer running performance does not appear to be the main cause of post soccer match-induced fatigue. Physical data provided by video match analysis systems is insufficient to accurately estimate the level of match fatigue.
