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:
1. Does blood flow restriction training improve neuromuscular function compared with conventional training? 2. Does blood flow restriction training improve muscle strength, power, body composition, physiological responses, and artistic jump rope performance?
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.
Trial opening soon.

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
Exclusion criteria
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.
Time frame: Baseline and after 8 weeks of intervention
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
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
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
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).
Time frame: Baseline and after 8 weeks of intervention
Upper limb anaerobic power will be assessed using a 30-second upper limb Wingate test performed on an arm crank ergometer. Outcome measures include peak power output (W), mean power output (W), relative peak power output (W/kg), total work (J), and fatigue index (%).
Time frame: Baseline and after 8 weeks of intervention
Lower limb anaerobic power will be assessed using Wingate cycling tests. Outcome measures include peak power output (W), mean power output (W), relative peak power output (W/kg), total work (J), and fatigue index (%). A 6-second Wingate test will assess explosive power, and a 30-second Wingate test will assess anaerobic capacity and fatigue-related performance.
Time frame: Baseline and after 8 weeks of intervention
Body composition will be assessed using dual-energy X-ray absorptiometry (DXA). Outcome measures include body mass (kg), body fat percentage (%), fat mass (kg), lean body mass (kg), and bone mineral content (kg).
Time frame: Baseline and 8 weeks after intervention
Physiological responses will be assessed using heart rate monitoring and blood lactate testing. Outcome measures include resting heart rate (beats/min), peak heart rate (beats/min), heart rate recovery (beats/min), and blood lactate concentration (mmol/L).
Time frame: Baseline and 8 weeks after intervention
Dynamic balance performance will be assessed using the Y Balance Test. Outcome measures include anterior reach distance (cm), posteromedial reach distance (cm), posterolateral reach distance (cm), and composite reach score (%).
Time frame: Baseline and after 8 weeks of intervention
Short-duration rope turning performance will be assessed using a 10-second maximal rope turning test. Outcome measures include total repetitions completed within 10 seconds and average movement frequency (repetitions/s).
