Brief Summary

The effect of the Copenhagen Adduction Exercise on groin injuries rate among soccer players The Copenhagen adduction exercise is a body-weight exercise which mainly works the groin and hip Adductors. It has a large eccentric component, meaning the muscles are working whilst lengthening. The purpose of this study is to investigate the effect of the Copenhagen adduction exercise on groin injuries among soccer players. It hypothesized that Copenhagen adduction exercise has a beneficial effect in terms of groin injury prevention.

Outcome Measures

Primary Outcomes (2)

  • Incidence of initial injuries

    Injury is defined according to a consensus statement on injury definitions and data collection procedures in soccer studies; an injury will be recorded if it caused the player to be unable to completely participate in the following match or training session.Injury rates will be summarised as number of injuries per 1000 player-hours for both matches and training. Exposure time in hours will be calculated for each team over a 6-month period. Data will be collected from Sports Injury Tracker injury reporting form. Coaches in both the experimental and control groups will be reporting injuries during training and matches by filling in forms once per week and submitting the information using the Sports Injury Tracker injury reporting form (Sports Medicine Australia). Injury rates will be summarised as number of injuries per 1000 player-hours for both matches and training. Exposure time in hours will be calculated for each team over a 6-month period.

    At the end of the intervention season (6 months)

  • The incidence of recurrent injuries

    Recurrent injury is defined as a repeat episode of a fully recovered injury. Injury is defined according to a consensus statement on injury definitions and data collection procedures in soccer studies; an injury will be recorded if it caused the player to be unable to completely participate in the following match or training session. Data will be collected from Sports Injury Tracker injury reporting form.

    At the end of the intervention season (6 months)

Secondary Outcomes (2)

  • Injury severity

    At time of any injury occurring throughout intervention soccer season (6 months)

  • Compliance with the intervention

    At the end of the intervention season (6 months)

Study Arms (2)

Intervention group

EXPERIMENTAL

The intervention group will be instructed to include the Copenhagen adduction exercise into their warm up before training session (3 times per week) during one season (6 months). The Copenhagen adduction exercise is a body-weight exercise which mainly works the groin and hip adductor. It has a large eccentric component, meaning the muscles are working whilst lengthening.

Other: Copenhagen adduction exercise

Control group

ACTIVE COMPARATOR

The control group will practice their usual warm up. Usual warm up is defined as any basic exercises performed before a performance or practice to prepare the muscles for vigorous actions.

Other: Usual warm up

Interventions

The Copenhagen Adduction exercise is a simple isolated eccentric partner exercise and doesn't require special equipment and can be performed as a warm up activity on the pitch.

Intervention group

Usual warm up is defined as any basic exercises performed before a performance or practice to prepare the muscles for vigorous actions.

Control group
