运动终板的分型及运动训练对运动终板的影响

The Type of Motor Endplate and the Effects of Sports Exercise on It

运动终板在骨骼肌纤维上的分配是骨骼肌神经支配的表现形式,运动终板的形态结构和机能状态直接影响到肌肉的功能。它既是神经系统引起肌肉收缩的关键部位,也是肌肉疲劳的潜在衰竭点。通常,骨骼肌纤维形态改变的同时伴有运动终板形态结构的变化。因此,在运动训练条件下对运动终板的形态学研究,为加快骨骼肌纤维的收缩效率和提高运动员的成绩提供良好的理论依据。

The distribution of motor endplate on the skeletal muscle is the form that be controlled by nerve.The morphology and function of motor endplate affect the function of skeletal muscle.It is the critical region of contract,as well as the potential falure point of skeletal muscle.Generally,the morphologic change of skeletal muscle is accompanied by the morphology and function change of motor endplate.So the morphologic study of motor endpalte under exercise condition is the good warranty for improving the muscle's contract efficiency and athlete's improvements.
