The study will include 30 healthy artistic jump rope athletes aged 18 to 25 years. The main questions this study aims to answer are:\n\n1. Does blood flow restriction training improve neuromuscular function compared with conventional training?\n2. Does blood flow restriction training improve muscle strength, power, body composition, physiological responses, and artistic jump rope performance?\n\nResearchers will compare participants receiving blood flow restriction training with participants performing conventional training to determine whether blood flow restriction training provides additional benefits. Participants will complete an 8-week training program and undergo assessments before and after the intervention, including muscle function tests, physical performance tests, body composition measurements, and physiological response evaluations.",[28,29],"Neuromuscular Function","Athletic Performance Enhancement",[31,32,28],"Blood Flow Restriction Training","Artistic Jump Rope","NOT_YET_RECRUITING","2026-08-03",{"date":36,"type":37},"2026-08-06","ACTUAL",{"date":39,"type":22},"2026-08-30",{"date":41,"type":22},"2026-12-15",{"name":43,"class":44},"Shanghai University of Sport","OTHER",1,{"id":47,"slug":48,"hasResults":11,"nctId":49,"briefTitle":50,"officialTitle":51,"acronym":4,"eligibilityCriteria":52,"healthyVolunteers":16,"sex":17,"minAge":18,"maxAge":19,"enrollmentInfo":53,"targetDuration":4,"studyType":23,"phases":54,"briefSummary":55,"conditions":56,"keywords":4,"overallStatus":33,"whyStopped":4,"lastUpdateSubmitDate":57,"lastUpdatePostDateStruct":58,"startDateStruct":60,"completionDateStruct":62,"leadSponsor":64,"locationsCount":4},"100649545","effects-of-blood-flow-restriction-training-on-physical-function-muscle-adaptations-and-performance-in-roller-skaters-100649545","NCT07736157","Effects of Blood Flow Restriction Training on Physical Function, Muscle Adaptations, and Performance in Roller Skaters","Effects of Blood Flow Restriction Training on Neuromuscular Function, Jump Performance, and Dynamic Balance Under Non-Fatigued and Fatigued Conditions, and on Muscle Morphology, Body Composition, Strength, Physiological Responses, Anaerobic Performance, and Roller Skating-Specific Performance in Competitive Roller Skaters","Inclusion Criteria:\n\n1.

Both groups will complete the same standardized 10-week roller skating training program. The blood flow restriction training group will wear pressure cuffs individualized according to each participant's arterial occlusion pressure during selected training sessions three times per week, while the control group will complete the same training without blood flow restriction.\n\nBefore and after the intervention, participants will complete standardized assessments of muscle morphology using musculoskeletal ultrasound, body composition using dual-energy X-ray absorptiometry, and lower-limb strength using handheld dynamometry and one-repetition maximum tests. Physiological responses will be evaluated using blood lactate concentration and heart rate variability. Roller skating performance will be assessed using sprint, repeated-sprint, and endurance skating tests.\n\nNeuromuscular function, jump performance, and balance will also be assessed under both non-fatigued and fatigued conditions. Surface electromyography and force-platform data will be collected simultaneously during selected jump and single-leg balance tasks. The Y-Balance Test will be conducted separately without surface electromyography.\n\nThe study aims to determine whether blood flow restriction training improves muscle and neuromuscular adaptations, body composition, strength, physiological responses, and roller skating performance, and whether it helps roller skaters maintain neuromuscular function, jump performance, and balance during fatigue.",[29],"2026-07-25",{"date":59,"type":37},"2026-07-30",{"date":61,"type":22},"2026-08-20",{"date":63,"type":22},"2026-11-30",{"name":43,"class":44}]
