MUSCULOSKELETAL TRAINING AND MECHANICAL CHARACTERISTICS OF ATHLETES

Abstract

Introduction: Studying the biomechanical characteristics of lower limb muscles during depth jumps is of great significance, but it is also important in meeting the practical needs of strength training. Objective: To explore the musculoskeletal exercise training and mechanical characteristics of athletes’ lower limbs. Methods: Analysis and discussion of the test results of kinematics, dynamics and the EMG of 8 muscles of the lower extremity when athletes jump at different falling heights and different motion states. Results: Only by using different falling heights in a certain proportion can training efficiency be improved and the training effect of depth jumps reach the practical purpose of sports training. Conclusions: From the point of view of exercise physiology, the generation, storage and reuse of muscle elastic deformation energy and the reflex regulation of the central nervous system are the main reasons for the economic and efficient contractive ability of the extensor muscle group of lower limbs during depth jumps. From the point of view of muscle mechanical properties, the centrifugal contractility of lower limb muscles is the primary factor that determines the athletes’ lower limb muscle explosive push ability.
