简要总结
This study aims to investigate the effects of low-intensity blood flow restriction training (LI-BFRT) on lower-limb strength and kicking performance in taekwondo athletes. Blood flow restriction training is a method that partially restricts blood flow to the muscles during exercise, which may improve performance while reducing training load.
详细描述
This study investigates the effects of low-intensity blood flow restriction training (LI-BFRT) on neuromuscular performance in taekwondo athletes. BFRT involves the application of external pressure to the proximal limbs to partially restrict blood flow during exercise, creating a hypoxic and metabolically stressful environment that may enhance muscle activation and promote performance adaptations.
Participants are randomly assigned to either a LI-BFRT group or a high-intensity resistance training (HIRT) group. Both groups complete a 6-week lower-limb resistance training program performed three times per week. The LI-BFRT group performs exercises at low intensity under controlled occlusion, while the HIRT group performs conventional high-load resistance training.
Outcome assessments focus on lower-limb strength, explosive performance, and sport-specific kicking ability. These measures are used to evaluate the effectiveness of LI-BFRT compared with HIRT in improving performance-related outcomes.
This study aims to determine whether LI-BFRT can achieve comparable training effects to traditional high-intensity resistance training while using lower mechanical loads, providing a practical training strategy for taekwondo athletes.

研究组 & 干预措施
LI-BFRT
Participants perform low-intensity resistance training combined with blood flow restriction. External pressure is applied to the proximal limbs during exercise to partially restrict blood flow. The training program is conducted three times per week for 6 weeks.
干预措施: LI-BFRT (Other)
HIRT
Participants perform conventional high-intensity resistance training without blood flow restriction. The training program is conducted three times per week for 6 weeks.
干预措施: HIRT (Other)
结局指标
