Abstract / Description of output
Objectives: To investigate the impact of physical efforts performed in the period preceding activity as a potential risk factor of muscle injury during match-play within a sample of professional soccer players.
Design: Observational cohort study.
Methods: Match load (running [>14.4-19.8 km/h], high-speed running [>19.8 km/h to 25.2 km/h], sprinting [> 25.2 km/], leading and explosive sprint type) averaged in 1-minute and 5-minute periods prior to an event or non event for 29 professional outfield soccer players. Conditional logistic and Poisson regression models estimated the risk of injury for a 2 within-subject standard deviation in match load or 1-action increment in the number of sprinting activities, respectively. Associations were deemed beneficial or harmful based on non-overlap of the 95% confidence intervals against thresholds of 0.90 and 1.11, respectively.
Results: An increment in sprinting distance [+ 2-SDs = 11 meters] covered over a 1-minute period (odds ratio [OR]: 1.22, 95%CI, 1.12 to 1.33) increased the odds of muscle injury.
Conclusions: Our study provides novel exploratory evidence that the volume of sprinting during competitive soccer match-play has a harmful association with muscle injury occurrence.
