  Purpose

Few studies indicate that sprint performance may be impaired in football players with a previous hamstring strain injury. This exploratory cross-sectional study aim to compare sprint performance between football players with and without a previous hamstring strain injury. The findings may elucidate potential indications of insufficient rehabilitation following a hamstring strain injury.

Sprint performance data will be collected using the MySprint Iphone Application.

Due to pragmatic reasons and the exploratory nature of this study the aim is to include players on a team level.

Based on the prevalence of hamstring strain injuries the expected number of cases to be included are 10-20 football players with a previous hamstring strain injury, and a corresponding 80-90 number of healthy controls.

No outcomes will be weighted (flat outcome structure).

Further study details as provided by Lasse Ishøi, Hvidovre University Hospital:

Primary Outcome Measures:
  • Theoretical maximal force [ Time Frame: Baseline ]
    Measured using the MySprint Application during a repeated-sprint test consisting of 6x30-m sprints. The outcome measure is exploratory.

  • Theoretical maximal velocity [ Time Frame: Baseline ]
    Measured using the MySprint Application during a repeated-sprint test consisting of 6x30-m sprints. The outcome measure is exploratory.

  • Theoritical maximal power output [ Time Frame: Baseline ]
    Measured using the MySprint Application during a repeated-sprint test consisting of 6x30-m sprints. The outcome measure is exploratory.

  • Slope of the linear decrease on ratio of force as sprint velocity increases [ Time Frame: Baseline ]
    Measured using the MySprint Application during a repeated-sprint test consisting of 6x30-m sprints. The outcome measure is exploratory.
