Methods and Materials:Sixteen healthy young college students without requiring medical service for lower limb due to injury in past 6 months accept 8 weeks plyometric exercise training. Using nerve conduction velocity test, surface electromyography, isometric dynamometer, electrogoniometer and ultrasonography to detect the change of (1)muscle activation level.(2)number of α-motorneuron.(3)nerve conduction velocity. And the mechanical properties of muscle-tendon complex are including (1)fascicle length.(2)fascicle angle.(3)fascicle curvature in muscle(4)muscle composition and (1)stiffness (2)hysterisis in tendon and electromechanical delay are also analysis.
