Abstract

Objective: Based on the growth and training load traits of adolescent female judo athletes, this study examines low-load BFRT's effects on lower limb explosive power and sport-specific performance. Methods: Sixteen athletes were randomly divided into an experimental group (40% 1RM + 180 mmHg cuff pressure) and a control group (75–85% 1RM). Both groups underwent 6 weeks of intervention, three times per week. Results: Maximal lower limb strength: Both groups improved 1RM squat strength(P<0.01), the difference between groups was not significant. Lower limb explosive power: Experimental group outperformed control in CMJ height (P=0.042), peak power (P=0.028), and SJ height (P=0.019). Both groups improved reactive strength index (RSI). Sport-specific performance: Both groups significantly improved 20m sprint. For judo-specific anaerobic endurance (SJFT index), only experimental group improved significantly (P=0.009). No significant change in rapid throwing speed (sukashi speed) in either group. Conclusion: Six weeks of low-load BFRT can improves lower limb maximal strength as effectively as high-load training, with greater safety. It distinctly improves vertical jump power and judo-specific anaerobic endurance. Both methods equally enhance short-distance sprint speed. However, short-term isolated strength training has limited effects on technique-dependent movements; long-term technical training should be integrated.
