IRCT20230612058457N5 IRCT 2025-03-07 The University of Bu-Ali Sina Comparison of three stretching protocols after fatigue in football players The role of stretching protocols in enhancing post-fatigue performance and flexibility in soccer 2025-03-24 anticipated 40 Complete https://irct.ir/trial/82242 interventional Randomization: Randomized, Blinding: Single blinded, Placebo: Not used, Assignment: Parallel, Purpose: Prevention, Randomization description: In the present study, participants are randomly assigned to four groups—static, slow dynamic, fast dynamic, and control—using a lottery draw method by pulling names from a ball, Blinding description: After assigning participants to each group, the outcome assessor was unaware of (or: was blinded to) the group allocation. N/A Comparison of three types of stretching protocols pre and post of functional fatigue in soccer players. Intervention 1: Intervention group: Static stretching of the hamstrings and quadriceps will include standing hamstring stretches (standing with feet hip-width apart and knees straight, participants bend forward while lowering their heads and wrapping their hands around the calf of one leg) followed by calf raises (from an initial standing position with knees straight, participants raise one leg upward while bending at the hip). Quadriceps stretching will be performed using a standing quadriceps stretch (participants stand on one leg while bending the opposite knee and holding it behind them with one hand for balance) followed by lunges (participants position one foot forward and one foot back while bending the front knee). Each stretch will be held for 30 seconds with two repetitions (once for each leg). Intervention 2: Intervention group: The fast dynamic group will perform the stretches like the static group, with the only difference being that each movement will be done at 100 beats per minute. Intervention 3: Intervention group: The fast dynamic group will perform the stretches like the static group, with the only difference being that each movement will be done at 50 beats per minute. Intervention 4: Control group: The control group will engage in 5 minutes of active rest in the form of walking. Yes - There is a plan to make this available What will be shared: All data will be shared after anonymizing individuals, ensuring their non-identifiability. When: The data access period will start immeduately after the results are printed. To whom: The data will be made available to researchers, organizations, and institutions related to the field of football and also for publication in accessible journals. Conditions: In order to assist scientific research and promote the implementation of executive goals with a focus on reducing musculoskeletal injuries and enhancing the performance of football players in the field, Where to obtain: Mohammad Alimoradi/malimoradi@sport.uk.ac.ir How to obtain: Requests for access to data will be answered within a week Comments:

Control group: The control group will engage in 5 minutes of active rest in the form of walking. In the present study, flexibility is being examined. Timepoint: Before and after the application of the fatigue protocol. Method of measurement: Flexibility is assessed using the modified Thomas test and PKET. In the present study, balance is being investigated. Timepoint: Before and after the application of the fatigue protocol. Method of measurement: Balance is measured using the Y Balance Test. In the present study, agility is being investigated. Timepoint: Before and after the application of the fatigue protocol. Method of measurement: Agility is evaluated using the Illinois Agility Test. In the present study, speed is being examined. Timepoint: Before and after the application of the fatigue protocol. Method of measurement: Speed is assessed using the 20-meter sprint test. In the present study, vertical jump is being examined. Timepoint: Before and after the application of the fatigue protocol. Method of measurement: Vertical jump is assessed using the countermovement jump test.
