Brief Summary

The reverse Nordic curl is a body-weight exercise which mainly works the quadriceps and hip flexors. 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 reverse Nordic curl exercise on Quadriceps femoris muscles injuries among soccer players. It hypothesized that reverse Nordic curl exercise has a beneficial effect in terms of Quadriceps femoris muscles injury prevention.

Conditions

Quadriceps Tendon Rupture; Quadriceps Strained Tendon; Quadriceps Muscle Atrophy

Keywords

Injury Prevention Program; Reverse Nordic curl exercise

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. 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. 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)

Secondary Outcomes (2)

• Injury severity

• Compliance with the intervention

Study Arms (2)

Intervention group

EXPERIMENTAL

The intervention group will be instructed to include the reverse Nordic curl exercise into their warm up 15 to 20 mins before training session (3 times per week) during one season (6 months).

Other: Reverse Nordic curl 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
