Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention group will be instructed to perform the ‘11+’ as a warm up for 20 minutes before the training sessions and for 10 minutes warm down after the training sessions 3 times per week, during one season (6 months)
FIFA 11 + program manuals and videos: available to anyone through the 11+ website (http://f-marc.com/11plus/ ).

The FIFA 11+ program, including a total of 15 exercises. It incorporates three main components of exercise regime that include an initial running and active stretching session, followed by a core and leg strength exercise session after which a high speed planting and cutting exercise session is performed. These exercises mainly focus on strengthening the core and leg muscles to improve static, dynamic and reactive neuromuscular control, coordination, balance and agility.

Statistical methods / analysis
G*Power: Statistical Power Analyses for Windows Version 3.1.9.2 was used to calculate the sample size of 332 participants. which will be sufficient for this study, 166 in the intervention group, and 166 in the control group. To be able to detect 20 % reduction rate, power of 0.8 and a of 0.05 a sample sizes. That was obtained by using the overall FIFA 11+ risk ratio of 0.654 from Al Atter et al. Meta-Analysis.

The quantitative data will be analyzed using SPSS version 23.0. Descriptive statistics (means and standard deviations) will be used to describe baseline characteristics and exposure data. Intention-to-treat analysis will be used for injury incidence analysis.
