Abstract

The purpose of the present study was to examine the influence of workload prior to injury on injury (tissue type and severity) in professional soccer players. Twenty-eight days of retrospective training data prior to non-contact injuries (n=264) were retrospectively collated from 192 professional soccer players. Each injury tissue type (muscle, tendon and ligament) and severity (days missed) were categorised by medical staff. Training data were recorded using global positioning system (GPS) devices for total distance (TD), high speed distance (HSD; >5.5 m/s-1) and sprint distance (SPR; >7.0 m/s-1 19). Accumulated 1-, 2-, 3-, 4- weekly loads, coupled, uncoupled, EWMA 1:3 and 1:4 acute: chronic workload ratios (ACWR) were calculated for total distance (TD), and compared using a one-way ANOVA. Injury severity and ACWRs were compared using a bivariate correlation. There were no differences in accumulated 1-, 2-, 3- and 4- weekly loads and ACWR calculations between muscle, ligament and tendon injuries (P > 0.05). Correlations between each workload calculation and injury severity highlighted no significant associations (P > 0.05). The present findings suggest that the ability of accumulated weekly workload or ACWR methods to differentiate between injury type are limited using the present variables.
