      <study_design>Randomization: Randomized, Blinding: Single blinded, Placebo: Not used, Assignment: Parallel, Purpose: Supportive, Randomization description: In this study, participants are divided into two experimental and control groups using simple randomization. The randomization process will be done individually using the online tool Randomiser.org, which automatically generates a list of random numbers and assigns each participant to one of the groups. To prevent bias and ensure uniform distribution, the random sequence is designed in a way that group assignment occurs only after the initial stages are completed. Allocation concealment is achieved through computerized encoding software, where random codes are automatically assigned to each participant, and allocation information remains encrypted in the system until the final data analysis, Blinding description: After providing a general introduction to the study and the groups being investigated, participants in the present study will be randomly assigned to the experimental and control groups by chance. Additionally, the evaluator will be blinded to the group allocation of participants.</study_design>

      <i_freetext>Intervention 1: Intervention group: In the present study, the intervention group will perform three dynamic stretching exercises for the hip flexor muscles such as Iliopsoas and rectus femoris over eight weeks (five sessions per week). Initially, the players will run at their preferred speed for 5 minutes, followed by 4 minutes of active rest, which involves walking. After that, they will perform the exercises according to the protocol, and each stretching exercise will be executed three times over a distance of 20 meters. Players will rest for 10 seconds between each set of exercises. Intervention 2: Control group: In the present study, the control group will continue with their usual exercises, and no specific stretching protocol will be provided to them.</i_freetext>
