从生理学角度来讲,运动技术是通过运动实践建立起来的运动条件反射。体育教学的一个重要目的就是要使学生迅速而正确地掌握技术动作,充分发挥学生的机体潜力,加强学生对正确动作的掌握和防止错误动作的形成。 1.什么是正确的动作 在教学中要防止和纠正学生形成错误动作,就必须使学生对正确动作的概念有一个深刻的理解。有的学生认为短跑运动员跑得快,跳远运动员跳得远,他们的动作就是正确的动作。这种看法太笼统,有一定的片面性。按照现代科学的理解,正确动作应当是符合人体力学原理,主动肌和对抗肌配合协调,中枢神经系统对各器官的系统,尤其对参与完成正确动作的有关肌群的调节精确,能量供应方式合理,能源物质的消耗节省,从而使动作做得高度协调,连贯有节奏、完美。
Physiologically, motor technology is the reflection of exercise conditions established by exercise practice. An important purpose of physical education is to enable students to quickly and correctly grasp the technical actions, give full play to the potential of students ’bodies, enhance students’ mastery of correct actions and prevent the formation of wrong actions. 1. What is the right action In teaching to prevent and correct the formation of wrong students, we must make the students have a correct understanding of the concept of movement. Some students think sprinters run faster, long jump athletes jump far, their action is the right action. This view is too general, there is a certain one-sidedness. According to the understanding of modern science, the correct action should be in line with ergonomic principles, coordination of the active muscle and the antagonist muscle, the central nervous system on the various organs of the system, in particular, to participate in the correct action to regulate the muscles accurately, the energy supply is reasonable , The consumption of energy and material saving, so that the movement is highly coordinated, coherent rhythm, perfect.
