Brief Summary

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

Conditions

Neuromuscular Function; Athletic Performance Enhancement

Keywords

Blood Flow Restriction Training; Artistic Jump Rope; Neuromuscular Function

Outcome Measures

Primary Outcomes (1)

• 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).

  Baseline and after 8 weeks of intervention

Secondary Outcomes (9)

• Change in Upper Limb Muscle Strength Assessed by Hand Grip Strength Test

  Baseline and after 8 weeks of intervention

• Change in One-Repetition Maximum Strength

  Baseline and after 8 weeks of intervention

• Change in Lower Limb Explosive Power Assessed by Three-Dimensional Force Platform

  Baseline and after 8 weeks of intervention

• Change in Upper Limb Anaerobic Power During Wingate Test

  Baseline and after 8 weeks of intervention

• Change in Lower Limb Anaerobic Power During Wingate Test

  Baseline and after 8 weeks of intervention
