Abstract

The invention provides a laser type super-equal-length discus core strength training and motion information feedback monitoring device, relates to a discus core strength training and motion information feedback monitoring device and aims at solving the problem that an existing discus special sport is lack of a laser type super-equal-length core strength training means and a motion information feedback monitoring means performed in an unstable state. The laser type super-equal-length discus core strength training and motion information feedback monitoring device comprises an annular track, a crank connecting-rod mechanism, a rear driving mechanism, a balance training device having an information feedback function, a pressure sensor, two laser velocimeters, multiple lifters and multiple elastic fixing racks identical to the lifters in number. The crank connecting-rod mechanism comprises a crank, a connecting rod and a first motor. The balance training device having the information feedback function is arranged under the annular track and comprises a pedal, a balance base, a control circuit and three distance measuring sensors. The laser type super-equal-length discus core strength training and motion information feedback monitoring device is used for core strength training and motion information feedback monitoring of a super-equal-length discus subjected to laser velocity measurement.

Description

technical field [0001] The invention relates to a discus core strength training and motion information feedback monitoring device, which belongs to the technical field of sports. Background technique [0002] From an anatomical point of view, the core of the human body is the spine, hip joints and pelvis, which are located at the junction of the upper and lower limbs and serve as a connecting hub. Core strength includes core stability strength and core dynamic strength. Core stability strength It refers to the force ability of the core to resist displacement or rotation generated by the intramuscular contraction of the fixed muscles or some fixed muscles that are both fixed muscles and prime movers. Core dynamic strength refers to the force that the contraction of skeletal muscles causes the body to displace or rotate. Core strength is not only the main driving force for the stability of the human core, but also can actively exert force during the flow. Core strength traini...
