The goal of this randomized controlled trial is to investigate whether blood flow restriction training can improve physical function and sports performance in artistic jump rope athletes. The study will include 30 healthy artistic jump rope athletes aged 18 to 25 years. The main questions this study aims to answer are:
Researchers 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.
Blood flow restriction (BFR) training is an exercise method that uses external pressure to partially restrict blood flow during exercise. This method may allow individuals to achieve improvements in muscle function and physical performance while using lower exercise loads. However, the effects of BFR training in artistic jump rope athletes are not fully understood.
The purpose of this study is to examine the effects of an 8-week blood flow restriction training program on neuromuscular function, body composition, physiological responses, and sport-specific performance in artistic jump rope athletes.
Approximately 30 healthy artistic jump rope athletes aged 18 to 25 years will participate in this study. Participants will be randomly assigned to either a blood flow restriction training group or a conventional training group. Both groups will continue their regular artistic jump rope training during the intervention period. The blood flow restriction training group will complete selected training sessions with individualized blood flow restriction pressure.
Before and after the 8-week intervention, researchers will assess changes in neuromuscular function, upper and lower limb muscle strength, explosive power, jump rope-specific performance, body composition, heart rate responses, and blood lactate responses.
This study may provide information about whether blood flow restriction training can be used as an effective training strategy to improve physical function and performance characteristics in artistic jump rope athletes.

Exclusion Criteria:
1. Age younger than 18 years or older than 25 years. 2. Presence of cardiovascular disease, peripheral vascular disease, respiratory disease, neurological disease, metabolic disease, coagulation abnormalities, history of thrombosis, severe varicose veins, severe hypertension, or other conditions that may affect exercise testing or blood flow restriction training safety.
3. Current acute or chronic injuries involving muscles, joints, ligaments, tendons, or bones that prevent safe completion of study procedures.
4. Severe fatigue, poor recovery status, significant pain, insufficient sleep, or other conditions that may influence exercise performance or participant safety.
5. Use of medications, nutritional supplements, or sports supplements that may affect cardiovascular function, muscle metabolism, blood lactate response, heart rate variability, neuromuscular activation, fatigue response, or exercise performance within the previous week.
6. Skin damage, infection, dermatological disorders, severe allergy history, or other conditions affecting blood flow restriction cuff application or surface electromyography electrode placement.
7. Inability or unwillingness to complete study assessments, blood flow restriction training, blood lactate testing, or other required procedures.
8. Withdrawal of consent or inability to comply with the study protocol during the intervention period.
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Behavioral: Blood Flow Restriction Training
Behavioral: Conventional Artistic Jump Rope Training
An 8-week blood flow restriction training program combined with regular artistic jump rope training. External pressure will be applied using a blood flow restriction device during selected training sessions.
An 8-week conventional artistic jump rope training program without blood flow restriction.
Change in Neuromuscular Function Assessed by Surface Electromyography and Maximal Voluntary Contraction
Neuromuscular function will be assessed using surface electromyography (sEMG) and maximal voluntary contraction (MVC) testing. Outcome measures include muscle activation amplitude, root mean square (RMS, μV), integrated electromyography (iEMG, μV·s), mean power frequency (MPF, Hz), and maximal voluntary contraction force (N).
Time frame: Baseline and after 8 weeks of intervention
Change in Upper Limb Muscle Strength Assessed by Hand Grip Strength Test
Upper limb muscle strength will be assessed using grip strength testing. The outcome measure is maximal voluntary grip force (kg) measured during maximal effort contraction.
Time frame: Baseline and after 8 weeks of intervention
Change in One-Repetition Maximum Strength
Maximal muscle strength will be assessed using one-repetition maximum (1RM) testing. The outcome measure is the maximal load successfully completed during the strength test (kg).
Time frame: Baseline and after 8 weeks of intervention
Change in Lower Limb Explosive Power Assessed by Three-Dimensional Force Platform
Lower limb explosive power and jump performance will be assessed using a three-dimensional force platform during jump testing. Outcome measures include jump height (cm), peak ground reaction force (N), peak power output (W), and rate of force development (N/s).
