Description of intervention(s) / exposure
The intervention group will be instructed to perform the FIFA 11+ shoulder injury prevention program (FIFA 11+S) during one season (6 months). Group sessions will be administered by an exercise physiologist and/ or athletic trainer and/ or soccer coaches and/ or strength and conditioning specialists and/ or physiotherapist.. The program consists of three parts: general warming-up exercises (part I), exercises to develop strength and balance of the shoulder, elbow, wrist, and finger muscles (part II), and advanced exercises for core stability and muscle control (part III). The FIFA 11+S takes ~20–25 minutes to complete and replaces the usual warm-up before training.
All exercises focus on core stability, neuromuscular control, eccentric rotator strength, and agility.

Part I – Warm-up exercises (should be performed for 7 minutes.)

Relaxed walking or running.
The speed can be progressively increased. 5 min

With both hands in front of the body, throw and catch the ball, first with your elbows flexed and then with your arms over your head. 1 min
3 Spinning movements with the hands
Interlace the fingers and make spinning movements with the hands. 1 min.
Part II – strength and balance of the shoulder, elbow, wrist, and finger muscles (should be performed in 9–10 minutes at 3 sets of 15 repetitions). Exercises should be changed according to the tolerance of the athlete (to A for B and C exercises)

6 Plyometric external rotation
Flexed elbow in 90° and flexed and abducted arm in 90°. Hold the elastic and make movements from neutral to lateral rotation quickly.

These exercises should be performed three times per week and should be added to the training taken by the soccer goalkeeper. Part I exercises should be done for 7 minutes as a general warm-up. Part II exercises should be performed for 9–10 minutes in a low-resistance (light tubing strength or 2–3 kg), high-repetition format (three sets of 15–20 repetitions), in order to improve strength and local muscular endurance.
Exercise should be changed according to the tolerance of the athlete (to A instead of B and C exercises). In part III, the athlete must do the exercises at high velocities with five or six sets of 15–20 repetitions not exceeding 9–10 minutes; these exercises are performed to increase local muscular endurance.

Program compliance will be evaluated according to the players’ rate of participation using an attendance log. The investigator will randomly visit one team selected from each group each week throughout the study period to motivate the teams and to ensure that the program is being followed conscientiously and correctly.

Outcomes
Primary outcome [1] 306237 0
Incidence of initial shoulder /upper 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.
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.
Timepoint [1] 306237 0
At the end of the intervention soccer season.
A General Estimating Equation (GEE) with an intention-to-treat (ITT) analysis will be performed to compare the effect of the interventions on the number of incidence of initial injuries incurred for each player.
Primary outcome [2] 306238 0
Incidence of recurrent shoulder /upper extremity 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).

Secondary outcome [1] 347940 0
Injury severity is defined as time loss in days (days unable to train): minor (1 to 7 days lost), moderate (8 to 21 days lost), or severe (>21 days lost). Injury severity data will be collected from Sports Injury Tracker injury reporting form.
