U.S., July 21 -- ClinicalTrials.gov registry received information related to the study (NCT07715786) titled 'Blood Flow Restriction During Nordic Hamstring Exercise in Elite Adolescent Athletes' on July 13.

Brief Summary: This crossover experimental study aims to compare acute hamstring muscle oxygenation responses during Nordic Hamstring Exercise (NHE) and Blood Flow Restriction Nordic Hamstring Exercise (BFR-NHE) in elite adolescent athletes. Participants will complete both exercise conditions in a randomized order separated by a 7-day washout period. Muscle oxygen saturation will be assessed using near-infrared spectroscopy (MOXY), together with total hemoglobin responses, blood lactate concentration, perceived exertion, and exercise pe...
