Abstract
The invention relates to a javelin training and information feedback monitoring device, in particular to a laser type super-equal-length javelin core strength training and information feedback monitoring device. The problem that no core strength training and quantization monitoring device which can be combined with a special javelin under the instable state exists at home and abroad can be solved. A lifting assembly is installed on a balance training mechanism with the information feedback function, a dial is installed at the upper end of the lifting assembly through a rotating shaft, the javelin is connected with a sliding sleeve through an adapting piece, a pressure sensor is installed on the javelin, an inverted motor is fixedly installed on the sliding sleeve, an idler wheel is installed on the rotating shaft of the inverted motor in a sleeved mode and is in rolling connection with a sliding rail, a stop dog is fixedly installed on the sliding rail, the inverted motor stops rotating after touching the stop dog, and a laser speedometer is fixedly installed at the front end of the sliding rail. The laser type super-equal-length javelin core strength training and information feedback monitoring device is used for javelin core strength training.
Description
technical field [0001] The invention relates to a javelin training and information feedback monitoring device, in particular to a laser type super isometric javelin core strength training and information feedback monitoring device, which belongs to the field of sports. Background technique [0002] From an anatomical point of view, the core of the human body refers to the spine, hip joints, and pelvis, which are at the junction of the upper and lower limbs and serve as a link between the preceding and the following. Core strength includes core stability strength and core dynamic strength. Core stability strength refers to the ability of the core to resist or rotate the body when the fixator muscles or some muscles that are both fixator muscles and prime mover muscles contract. Core dynamic strength refers to the force of skeletal muscle contraction to produce displacement or rotation of the body. Core strength is not only the main driving force for the formation of the cor...
