Randomization will be performed using a simple individual-level method. The random allocation sequence will be generated using the random number generation function in Microsoft Excel. A random number will be assigned to each participant, and the participants will then be sorted in ascending order based on these numbers. They will subsequently be allocated in a 1:1 ratio to the neuromuscular exercise group and the control group. Group allocation will be performed after completion of the baseline assessments. The random sequence will be kept concealed until the final allocation, Blinding description: Because of the nature of the exercise intervention, blinding of the participants will not be possible. However, the assessors of the functional and biomechanical tests and the statistical data analyst will be blinded to group allocation. This approach will be used to reduce measurement and analysis bias. N/A Dynamic knee valgus. Intervention 1: Intervention group: Implementation of a neuromuscular training protocol focusing on improving motor control, balance, and landing pattern modification. The training will be performed for 8 weeks, 3 sessions per week, with each session lasting 40 to 50 minutes under direct supervision. The training program consists of the following components: warm-up (5 to 10 minutes of light running and dynamic stretching), proprioception and balance exercises (15 minutes on stable and unstable surfaces), plyometric and landing modification exercises (15 minutes of various jumps with emphasis on proper knee alignment and soft landing), core and hip stabilizer strengthening exercises (10 minutes), and cool-down (5 minutes of static stretching). Intervention 2: Control group: Subjects in this group will not receive any additional training or exercise intervention outside of their daily routine and regular soccer team training during the 8-week study period, and will only continue their routine sports activities. No - There is not a plan to make this available Justification or reason for not sharing IPD is Due to the confidentiality of the adolescent participants’ personal data and to comply with research ethics principles, individual participant data will not be shared.
