The goal of this clinical study is to investigate the effect of fatigue on balance, core endurance and player performance in adolescent football players. the main questions it aims to answer are:
This study will be conducted in This pre and post controlled trial aiming at determining the efficacy of fatigue on core endurance, balance and player performance in adolescent football players, this study will be conducted in Wadi-Degla football club.
Players will be randomly assigned into either fatigue or control group. Randomizations will be done using computer random generated numbers.
Fatigue group (F.G): 30 players will be assessed for core endurance, balance and performance then fatigue protocol will be applied and reasses for core endurance, balance and performance after fatigue Control Group (C.G): 30 players will be assessed for core endurance, balance and performance.
Players will be assessed at baseline and fatigue for: balance using (MFT challenge disc),Core endurance, 20-m running sprint and Triple-Hop Test (THT) for perfprmace Will apply RSA as fatigue protocol for the fatigue groupe.
Inclusion criteria:
Players will be included according to the eligibility Criteria

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Fatigue group | Experimental | 30 male players will be assessed for core endurance, balance and performance then fatigue protocol will be applied and measure for core endurance, balance and performance after fatigue |
|
| Control group | Sham Comparator | 30 players will be assessed for core endurance, balance and performance. Players will be assessed at baseline then take rest drink water and then measure for core endurance, balance and performance again . |

| Fatigue protocol (repeated sprint ability) | Other | The test performed on an outdoor field (artificial grass carpet) in the form of 6 repetitions of maximal 2× 15 m shuttle sprints interspersed with 20 seconds of passive recovery , Before the RSA protocol, all players perform a brief standardized warm-up (approximately 20 minutes long), in 1at submaximal speed (followed by 40 seconds of passive recovery The fatigue index (FI) used to characterize the RSA performance was calculated in terms of percentage decrement score At the end of the RSA protocol , usually the time elapsed between the end of the last sprint and the beginning of the measurements was no more than 20 seconds, to avoid masking effects related to progressive recovery from fatigue. |
