Influence of Lower Limb Resistance Training on the Explosive Quality of Athletes

Abstract

Introduction: Athletics demands high explosive strength from its athletes, and complementary techniques are constantly implemented to maintain the competitive level of its practitioners. And is believed that resistance training can benefit track and field athletes. Objective: Explore whether lower limb resistance exercise can effectively increase the explosive quality of track and field athletes. Methods: We randomly divided 88 professional track and field athletes into experimental and control groups, who underwent training for 12 weeks. The experimental group received lower limb-specific resistance training, while the control group underwent general training. Results: After the lower limb resistance training intervention, the athletes showed evolution in the standing triple jump, from 7.63±0.179m to 7.94±0.12m. The average 30-meter running time also showed gains from 4.55±0.23s to 4.17±0.13s, and the YOYO running distance increased from 979.48± 134.11m to 1139.28±107.84m. The sitting flexion distance increased from 16.91±4.86cm to 17.65±3.39cm, and the solid ball throwing distance went from 20.03±2.05m to 21.24±2.35m. Conclusion: Lower limb resistance training can effectively improve the explosive power of professional track and field athletes.
