What this Trial Is About
Researchers are evaluating the effects of combining active recovery (AR) and blood flow restriction (BFR) on post-exercise recovery in healthy amateur male runners aged 18 to 40 years who run faster than 5:30 min/km. The study aims to determine if using both techniques together offers better recovery outcomes compared to active recovery alone or complete rest after exercise. Participants will be randomly assigned to one of three groups: active recovery with blood flow restriction using a pneumatic cuff at 60% occlusion pressure for 10 minutes, active recovery without restriction for 10 minutes, or passive rest without movement for 10 minutes. All participants will complete baseline assessments and a muscle stress protocol before applying their assigned recovery method. During the study, researchers will assess heart rate variability, muscle soreness, recovery perception, discomfort, effort, cellular integrity, pain threshold, muscle tone, stiffness, elasticity, muscle power, plantar flexor strength, and aerobic capacity at baseline and at intervals up to 96 hours after exercise. Participants will provide informed consent and may allow data sharing with universities or regulatory authorities. The study includes follow-up evaluations immediately and at 24, 48, 72, and 96 hours post-exercise.
