Brief summary
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.
Detailed description
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.

Intervention model description
Participants are randomly assigned to two parallel groups: a low-intensity blood flow restriction training (LI-BFRT) group and a high-intensity resistance training (HIRT) group. Both groups complete a 6-week training intervention, and outcomes are assessed before and after the intervention.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Sport-specific kicking performance | Baseline and after 6 weeks | Sport-specific kicking performance is assessed using a standardized kicking test, including kicking frequency and kicking decrement index during repeated kicking tasks. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Lower-limb strength | Baseline and after 6 weeks | Lower-limb strength is assessed using thigh circumference, countermovement jump height, and one-repetition maximum squat. |
| Anaerobic performance | Baseline and after 6 weeks | Anaerobic performance is assessed using the Wingate anaerobic test, including peak power, mean power, relative peak power, and relative mean power. |
