Description

Vibration isometric multi-angle hammer special strength training and monitoring device

technical field

The invention relates to a hammer throw special strength training and monitoring device.

Background technique

At present, the hammer throw special strength training uses isotonic (also known as dynamic) exercises, such as: swinging with heavy objects, throwing heavy objects, etc., but not enough attention is paid to isometric (also called static) exercises, and the means are lacking. What's more, there is a lack of monitoring the technical process of athletes' movements. Research has shown that isotonic exercises combined with isometric exercises are very effective for developing strength. There is a new theory of vibration isometric training strength, using 5 Hz to 26 Hz sinusoidal wave vibration to perform short isometric training on an action is very effective for developing strength. Isometric training is only effective for the maximum strength of a certain angle of the joint and a small area (±15°) around it. In order to improve the maximum muscle strength of the entire joint range of motion, isometric training should be performed at different angles of the joint. The ability to use explosive isometric contractions to develop a muscle's force-generating velocity is even more effective for developing explosive power than isotonic (dynamic) exercises.

However, it can make good use of the latest research results, conform to the development direction of modern high-level hammer throw special strength training (that is, strength training methods that are closer to special movements), and use athlete movement information to monitor the athlete's movement technical process. The vibration isometric multi-angle Hammer throw special strength training and monitoring device have not yet occurred at home and abroad.
