IRCT20250424065462N1 IRCT 2025-08-24 Tehran University of Medical Sciences Effect of blood flow restriction on the performance of sprinters Immediate effects of plyometric depth drop jump and landing exercise with and without blood flow restriction on neuromuscular control and cognitive function in sprinters 2025-09-05 anticipated 27 Complete https://irct.ir/trial/83135 interventional Randomization: Randomized, Blinding: Single blinded, Placebo: Not used, Assignment: Parallel, Purpose: Supportive, Randomization description: Sealed envelopes are prepared corresponding to the number of participants. Half of the envelopes are labeled 'Control - Plyometric,' while the other half are labeled 'Plyometric and Blood Flow Restriction.' Each participant selects an envelope at random from the two groups without viewing its contents, Blinding description: Participants will not be aware of their group. They will not participate on the same day and time. In both intervention and control groups, the cuff of the blood flow restriction device is closed in the proximal of lower limb. In the intervention group, the cuff pressure is measured and adjusted to the desired level, but in the control group, the cuff remains empty and is used to eliminate the placebo effect. N/A Healthy male sprinters. Intervention 1: Intervention Group :The cuff of the device is placed on the proximal thigh of both limbs, and the cuff pressure is inflated to 40% of the arterial occlusion pressure. Then, the participant performs drop jump exercises from a height of 15 centimeters for two sets of 8 repetitions, resting for 3 minutes between each set. Intervention 2: Control Group :The cuff of the device is placed on the proximal thigh of both limbs, but the cuff is not inflated. Then, the participant performs drop jump exercises from a height of 15 centimeters for two sets of 8 repetitions, resting for 3 minutes between each set. No - There is not a plan to make this available Justification or reason for not sharing IPD is Participants' data will remain confidential.
