Abstract

Abstract : Background: The FIFA11+ is a dynamic warm-up injury prevention program. Previous studies have examined its efficacy in reducing injuries, however no information is available on whether it changes targeted movement patterns. Objective: The purpose of this study was to examine the changes in peak knee abduction moment (PKAM) over two soccer seasons using the FIFA11+. We hypothesized that athletes will have decreased PKAM over the first season, no changes in the off-season, and further decreases over the second season. Design: Prospective non-randomized intervention study (control team data currently being collected). Setting: Elite collegiate women's soccer. Patients (or Participants): First season N=83, off-season N=68, second season N=59. Interventions: The FIFA11+ program was initiated during the preseason and completed throughout two consecutive soccer seasons as a warm-up prior to training sessions and games at least 3x/week. Researchers did not influence the training during the off-season. Main Outcome Measurements: PKAM measured during motion analysis of a drop jump at pre- and postseason of two consecutive seasons. Repeated measures ANCOVAs were used to analyse the change over each season and the off-season, with baseline PKAM included in each model as a covariate. Results: There was a significant main effect of time over the first season (preseason 0.24±0.01, postseason 0.23±0.01, p=0.02). PKAM was a significant covariate (p<0.01). There no main effect of time over the off-season (p=0.40), however, PKAM was a significant covariate (p<0.01). There was also no main effect of time over the second season (p=0.29), with PKAM again a significant covariate (p<0.01). Conclusions: The FIFA11+ is effective in preventing injuries, however its mechanism is unknown. The preliminary results of this study indicate this injury reduction may not be occurring as a result of a decrease in PKAM in all athletes.
