Description

Vibration isometric multi-angle chest-leg combined strength training and monitoring device

technical field

The invention relates to a chest-leg combined strength training and monitoring device.

Background technique

At present, special strength training such as wrestling and throwing uses isotonic (also known as dynamic) exercises, such as: bench press, chest expansion, squat barbell, etc., but insufficient attention is paid to isometric (also called static) exercises , the lack of means, and the lack of isometric strength exercises combined with special multiple muscle groups and the monitoring of the technical process of athletes. 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, which is in line with the development direction of modern high-level wrestling, throwing and other special strength training (that is, the strength training method that is closer to the linkage of multiple muscle groups in special movements), and uses athlete movement information to influence athlete movements.
