Control device for last strength in javelin throwing teaching

Abstract

The invention discloses a control device for last strength in javelin throwing teaching. The control device comprises a vertical pillar A and a vertical pillar B, wherein the vertical pillar A and the vertical pillar B are fixedly arranged in a spaced mode and are different in height; the vertical pillar A is higher than the vertical pillar B by a certain size; a javelin guide steel rope is connected between the upper part of the vertical pillar A and the upper part of the vertical pillar B, and an exercise javelin is arranged on the javelin guide steel rope in a length direction in a sliding mode; and a height-angle regulating device, which is used for regulating the exercise javelin, is arranged on the vertical pillar A and the vertical pillar B. The control device disclosed by the invention has the technical characteristics and advantages that by virtue of the control device, students, in an exercise process, can master the last strength and throw the javelin by an appropriate angle; and through repeated training, a good muscle power exertion feeling can be established, so that stable dynamic finalization is formed, and the technical problem of old imitation which, through bare-handed exercise, is inconvenient to master transition of javelin running-up and last strength is solved.

Description

technical field [0001] The invention relates to a control device for javelin final force teaching, which belongs to the technical field of sports equipment. Background technique [0002] The javelin throw is an all-around competition for male and female teenagers stipulated by the IAAF, the State General Administration of Sports, and the Ministry of Education. The complete technique of throwing the javelin includes four parts: holding the gun, holding the gun, running up, final force and buffering. Among them, the final force is the most important technical part of throwing the javelin, which determines the instant speed, angle and position of the javelin in the air. The state of flying, but the current school teaching and training process lacks special training equipment for javelins. Practitioners do not have a clear understanding or reference objects for using force along the longitudinal axis of javelins and shooting at an appropriate angle. The old imitation teaching ha...

Problems solved by technology

[0004] Aiming at the shortcomings of the existing javelin's final force and the angle of release that are not easy to grasp, the present invention provides a control device for teaching the javelin's final force. The device is easy to operate, occupies a small area, and can reasonably control the height and angle of the javelin. Establish a good feeling of muscle exertion and form a standardized final exertion movement, which can effectively shorten the training cycle
