We analysed the time course of recovery of creatine kinase (CK) and countermovement jump (CMJ) parameters after a football match, and correlations between changes in these variables and match time–motion parameters (GPS-accelerometry) in 15 U-19 elite male players. Plasma CK and CMJ height (CMJH), average concentric force (CMJCON) and average eccentric force (CMJECC) were assessed 2 h before and 30 min, 24 h and 48 h post-match. There were substantially higher CK levels 30 min, 24 h and 48 h (ES: 0.43, 0.62, 0.40, respectively), post-match. CMJECC (ES: −0.38), CMJH (ES: −0.35) decreased 30 min post, CMJCON (ES: −0.35), CMJECC (ES: −0.35) and CMJH (ES: −1.35) decreased 24 h post, and CMJCON (ES: −0.41) and CMJH (ES: −0.53) decreased 48 h post. We found correlations between distance covered at velocities ≤21 km · h−1 and changes in CK at 24 h (r = 0.56) and at 48 h (r = 0.54) and correlations between CK and distance covered >14 km · h−1 (r = 0.50), accelerations (r = 0.48), and decelerations (r = 0.58) at 48 h. Changes in CMJCON 30 min and 24 h post (both r = −0.68) correlated with impacts >7.1·G. Decelerations >2 m · s−2 correlated with changes CMJCON (r = −0.49) at 48 h and CMJECC (r = −0.47) at 30 min. Our results suggest that match GPS-accelerometry parameters may predict muscle damage and changes in components of neuromuscular performance immediately and 24–48 h post-match.
