Research on the Mechanism of the Effects of Different Loading Methods on Lower Limb Explosive Power Training Based on Biomechanical Analysis

Abstract

This study comprehensively investigates the biomechanical mechanisms underlying the effects of different loading methods on lower limb explosive power training, a critical component in athletic performance and physical rehabilitation. By systematically analyzing joint kinetics, muscle activation patterns, and neuromuscular coordination under varying external loads, the research aims to clarify precisely how specific load types and magnitudes influence physiological adaptations and overall training outcomes. Through the rigorous application of advanced motion capture technology, force platform testing, and electromyographic analysis, dynamic biomechanical parameters are meticulously obtained and subsequently integrated into a comprehensive, multi-dimensional evaluation model. The empirical findings demonstrate that distinct loading methods induce highly differentiated stress distribution across the musculoskeletal system, alter motor unit recruitment strategies, and significantly impact energy transfer efficiency throughout the kinetic chain. Consequently, these biomechanical variations produce markedly varied effects on the development of lower limb explosive power, highlighting the necessity for highly individualized training prescriptions. Furthermore, the integration of these biomechanical insights allows for a deeper understanding of injury prevention mechanisms during high-intensity resistance exercises. Ultimately, this study provides robust theoretical guidance and evidence-based practical strategies for coaches, clinicians, and athletes. By optimizing lower limb training programs, these insights facilitate significant advancements in sports performance enhancement, functional movement efficiency, and targeted rehabilitation practice.
