Description of intervention(s) / exposure
The effects of the Copenhagen exercise (CE) and Nordic hamstring exercise (NHE) have been evaluated and shown reduce in injury incidence significantly. However, the effects of the CE or NHE protocol on improving functional balance have not been investigated and yet may be important. Therefore, we will evaluate the effect of CE and NHE on improving functional balance compare to no intervention, among amateur male athletes.
Methods: male amateur athletes aged 19–25 years will be randomly assigned to CE and NHE intervention groups (n=20 athletes), CE intervention group (n= 20 athletes), NHE intervention groups (n= 20 athletes) or a control group (n= 20 athletes).
The Copenhagen Exercise. The CE exercise is a partner exercise in which the player lies on his or her side with one forearm as support on the floor and the other arm placed along the body. The upper leg is held at approximately hip height of the partner, who holdsthe leg with one arm supporting the ankle and the other supporting the knee. The player then raises his or her body from the field and the lower leg is adducted so that the feet touch each other and the body is in a straight line The body is then lowered halfway to the ground while the foot of the lower leg is lowered so that it just touches the floor without being used for support. The exercise is performed on both sides.
The Nordic Hamstring Exercise. The NHE is performed in pairs. Players start in a kneeling position, with the torso from the knees upward held rigid and straight. The training partner ensures that the player’s feet are in contact with the ground throughout the exercise by applying pressure to the player’s heels/lower legs. The player then lowers his upper body to the ground, as slowly as possible to maximize loading in the eccentric phase. Hands and arms are used to break his forward fall and to push him back up after the chest has touched the ground, to minimize loading in the concentric phas.
Exercise Prescription for the CE and NHE:
Beginner 3 Training Sessions Per Week 1 Set 3-5 Repetitions
Intermediate 3 Training Sessions Per Week 1Set 7-10 Repetitions
Advanced 3 Training Sessions Per Week 1Set 12-15 Repetitions
Compliance will be evaluated according to the players’ rate of participation using an attendance log.
The total duration of the intervention is 6 weeks.
Intervention administers: Physiotherapist and Senior Physiotherapy students.

Incidence of lower extremity 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.
This data will be collected using Sports Medicine Australia injury reporting form

Summary
Brief summary
Background: The effects of the Copenhagen exercise (CE) and Nordic hamstring exercise (NHE) have been evaluated and shown reduce in injury incidence significantly. However, the effects of the CE or NHE protocol on improving functional balance have not been investigated and yet may be important. Therefore, we will evaluate the effect of CE and NHE on improving functional balance compare to no intervention, among amateur male athletes.
Methods: male amateur athletes aged 19–25 years will be randomly assigned to CE and NHE intervention (n=2 groups, 20 athletes), CE intervention (n=2 groups, 20 athletes), NHE intervention (n=2 groups, 20 athletes) or a control group (n=2 groups, 20 athletes). All groups will perform the pre- post intervention test using Biodex Balance Stability System and functional balance tests. The primary outcome measure will be improving functional balance with factoring of the exposure time.
Conclusion: This cluster randomized controlled trial will provide level I evidence that implementation of CE or NHE can improving functional balance among male athletes, leading to reduce injury risk and decrease of injury related financial burden on the healthcare system.
