Effect of low-load resistance combined with single-leg pressure training on the explosive strength of lower limb muscles in athletes.

This article investigates the effects of low-load resistance training combined with single-leg pressurization (blood flow restriction, BFR) on lower limb explosive power (LLEP), coordination, and specialized performance in male triple jump athletes. Over an eight-week period, twenty male triple jumpers were randomly assigned to an experimental group receiving low-load resistance plus single-leg pressurization training or a control group undergoing traditional high-load single-leg resistance training. Results showed that the experimental group achieved significantly greater improvements in thigh muscle circumference, dynamic balance ability, isokinetic knee strength, countermovement jump power, one repetition maximum (1RM) squat strength, and triple jump performance compared to the control group. The study concludes that low-load resistance combined with single-leg compression training effectively enhances LLEP and athletic performance while reducing joint stress, offering a viable alternative to traditional high-load training for explosive sports like the triple jump.
