The invention relates to a final exertion auxiliary exerciser for javelin teaching. The final exertion auxiliary exerciser comprises a base, wherein a height regulating support is arranged on the base; an angle regulating base is arranged at the upper end of the height regulating support; an inclined rod body is fixed on the angle regulating base; and a casing pipe, which is capable of sliding along the rod body, is sheathed on the rod body. The final exertion auxiliary exerciser has the beneficial effects that: students can be assisted to exert forces along the vertical axis of a javelin from beginning to end in the exercise process and throw out the javelin at an appropriate angle. Through the final exertion auxiliary exerciser, the good muscular exertion feeling can be achieved through repeated exercises and further a stable dynamic stereotype is formed; and the final exertion auxiliary exerciser has the advantages of being capable of shortening the teaching hours and increasing the efficiency and quality of teaching.
Description
technical field [0001] The invention is an auxiliary device for the final forceful practice in the javelin teaching, especially suitable for the primary stage of the javelin teaching, and has a significant effect on improving and improving the final forceful action of high-level javelin athletes. Background technique [0002] At present, the final force practice in javelin teaching is usually carried out with a gun. The main means are sticking the gun in place and throwing the gun sideways in place. The purpose is to improve the ability to control the gun. Javelin thrown. In the actual practice process, students do not have a clear understanding of the force along the longitudinal axis of the javelin and shooting at an appropriate angle or a reference for reference, and often make mistakes such as pulling the gun, swinging the gun, swinging the gun, and shooting the javelin at too high or too low an angle action. The corrective method is only watching demonstrations, imita...
