Description of intervention(s) / exposure
Initially, participants will be familiarized with the protocol and assessment methods, This will be followed by 2 testing sessions which are separated by at least 3 days (Bossuyt et al., 2016). Both sessions included a dynamic warm-up, followed by the youth soccer fatigue simulation (YSFS5), a pretest (TIME 0), a test immediately following YSFS5 (TIME 5), after 15 min of passive rest (TIME 20) and after 30 min of passive rest (TIME 35). The distance for Youth Soccer Fatigue Simulation (YSFS5) is 12 meters and the time spent is 5 minutes. YSFS5 is using high-intensity exercises. Functional high-intensity movements were included in this simulation to make it more similar to the real soccer match. The participant needs to repeat the cycle of activities for 5 minutes. The action sequences are instructed using verbal cues on an audio recording. Before, during and after the simulation, the participant needs to be assessed in term of their heart rates, rates of perceived exertion (RPE) and heights of vertical jump. These monitored aspects are indicators to make sure the participant is a phase of high-intensity mode. If the participant is not in the mode, the oral encouragement should be applied to increase the desire of participant to be in the mode of high intensity. The YSFS5 consist of :

0. 6x Ball Passing
1 . Stand
2 . Up Jog
3. 6x Ball heading
4. Side Stride
5. Agility ladder drill + 1 x Ball shooting
6. VJ + up Jog
7. Sprint with a ball
8. Stand
9. Up Jog
10. 6x Ball Passing
11. VJ + up Jog
12. 6x Ball heading
13. Side Stride
14. Agility ladder drill + 1 x Ball shooting
15. Stand
16. Up Jog
17. 6x Ball Passing
18. VJ + up Jog
19. Jog
20. Up Jog
21. 6x Ball heading
22. VJ + Up Jog
23. Agility ladder drill + 1 x Ball shooting
24. Side Stride
25. Stand
26. 6x Ball Passing
27. Jog
28. Sprint with a ball
29. VJ
All these activities take about 5minutes.

After that, the participant will be randomly allocated to control and intervention group. Participants in the intervention group will be instructed to do FIFA 11+ program about 20minutes which are to use the complete exercise program as the warm up for at least two training sessions every week. The program has three parts. The initial part is running exercises at slow speed combined with active stretching and controlled contacts with a partner. The running course includes six to ten pairs of cones (depending on the number of players) about five to six meters apart (length and width). The running exercise such as running straight ahead and running quickly forwards and backward. The second part consists of six different sets of exercises; these include strength, balance, and jumping exercises, each with three levels of increasing difficulty. The second part example is the bench static, single leg stand and vertical jump. The final part is speed running combined with football-specific movements with bounding and plant-cut movements (Owoeye et al., 2014). This program will be completed by as part of a team warm up supervised by the coach. The training will be provided to the coach to run the program and also be given the handbooks. The researcher will monitor the program twice a week. The coach will keep a diary of program completion and player attendance to monitor the intervention program process. This intervention will be done for 8 weeks. Then all the participants will come back to the lab for repeating the same procedure for the outcome measure before YSFS5 and after YSFS5. The data collection will be assessed by the assessors who are blinded from the control and intervention group. In addition, the same assessors will be collected the data for pre and post-intervention.

Statistical methods / analysis
An a-priory calculation for sample size determination has been conducted from previous studies (Daneshjoo, Mokhtar, Rahnama, & Yusof, 2012) It was determined that to achieve 80% statistical power and an effect size of 0.514, a minimum number of 32 participants is required for this study. A 20% was added to reduce the possibility of the attrition rate. Therefore, 40 participants will be recruited.
Descriptive statistics of outcome measures will include means and standard deviations. A one-way repeated measures analysis of variance (ANOVA) will be used to investigate the influence of Youth Soccer Fatigue Simulation(YSFS5) on each dependent variable using statistical software package SPSS (Version 23; SPSS Inc., USA). Mauchly's test of sphericity will be used to check for equality of variance between simulations and different times. If the Greenhouse–Geisser epsilon will be >0.75 the Huynh Feldt correction will be used, if the epsilon was <0.75 the Greenhouse Geisser correction value will be used (Girden, 1992). Bonferroni procedures will be used for post-hoc analysis and alpha level was set at 0.05.
