Sprint Performance in Football Players With a Previous Hamstring Injury
ID: NCT03306511
Our intelligence engine has synthesized this trial record to answer your most important questions in clear, simple terms:
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).

Treatment Arms Description
Football players with a previous self-reported hamstring strain injury in the preceding 12 months
Football players without a previous self-reported hamstring strain injury in the preceding 12 months
- Able to participate fully in regular football training and matches
- Able to participate fully in regular football training and matches
- Self-reported hamstring strain injury resulting in loss of regular football training sessions or football matches in the preceding 12 months.
- Self-reported hamstring strain injury resulting in loss of regular football training sessions or football matches in the preceding 12 months.
- Longstanding injury (\>6 weeks) in the lower extremities or trunk in the preceding 12 months.
- Any pain in the lower extremity, pelvis, or spine during testing
- Longstanding injury (\>6 weeks) in the lower extremities (except hamstring strain injury) or trunk in the preceding 12 months.
- Any pain in the lower extremity, pelvis, or spine during testing
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.
