学生在练习技能时,借助来自本体感受器传入信息,通过大脑皮质下运动神经中枢和大脑皮质机能活动,相互密切联系来完成动作的练习,这种关系稍微不协调,运动的动作练习就不准确。由于中小学生本体感觉能力差,进而空间和体位感知能力不足,加上在短跑教学中,除了起跑的预备姿势以外,其他的动作都是在动态中完成的,造成了学生掌握技能的能力欠缺,所以说辅助器械的应用很重要。辅助器械的使用能帮助初 When practicing skills, students use the information from the ontological receptors to perform exercises through close contact with the motor nerve center and cerebral cortex under the cerebral cortex, which is a little uncoordinated and inaccurate exercise exercises . Due to the poor ability of primary and secondary school students to feel their body and the lack of perception of space and posture, in addition to the preparatory stance for starting sprint, all the other motions are accomplished in a dynamic manner, resulting in lack of ability of students in mastering skills, So the application of assistive devices is very important. The use of auxiliary equipment can help early
