A laser javelin core stabilization strength training and information feedback monitoring device

technical field

The invention relates to a javelin training and information feedback monitoring device, in particular to a laser type javelin core stability training and information feedback monitoring device.

Background technique

The core part of the human body is a whole formed by the waist, pelvis, and hip joints, and is the middle link of the human body. Core stability enables the human body to establish a fulcrum for the force of the limb muscles through the stability of the core during exercise, create conditions for the transmission of power from the upper and lower limbs, and provide a body posture that provides strength for the stability and movement of the center of gravity. The force that makes up or enhances core stability is core strength. The biggest difference between core strength training and traditional waist and abdomen strength training is that core strength training is carried out under unstable conditions in many cases, which can make more small muscle groups, especially the auxiliary muscles around the joints, participate in the movement, and cultivate athletes The ability to stabilize joints and control the center of gravity during exercise, the posture of core muscle training is determined by the action posture of the official competition. Modern high-level special strength training is to use strength training methods close to special movements, and use athlete movement information to monitor the technical process of athletes' movements. However, the core stability strength training and information feedback monitoring devices combined with the final force of the javelin have not yet appeared at home and abroad. .

Contents of the invention

In order to solve the problem that there is no core stability training and information feedback monitoring device combined with the final force of the javelin, the present invention further proposes a laser type javelin core stability training and information feedback monitoring device.

The technical scheme adopted by the present invention to solve the above-mentioned problems is: the present invention includes lifting components, dials, rotating shafts, slide rails, sliding sleeves, connectors, javelins, pressure sensors, laser velocimeters and balance training with information feedback functions mechanism, the lifting assembly is installed on the balance training mechanism with information feedback function, the dial is installed on the upper end of the lifting assembly through the rotating shaft, the slide rail is installed on the rotating shaft, and the sliding rail can be rotated as The axis rotates, the sliding sleeve is set on the sliding rail, the javelin is connected with the sliding sleeve through a connecting piece, the pressure sensor is installed on the javelin, and the laser speedometer is fixedly installed on the front end of the sliding rail.
