working principle

In order to overcome the unstable state and maintain a correct force posture, athletes need to mobilize and activate more core muscle fibers through the coordination of the waist, pelvis, hip joints and lower limbs to participate in stabilizing body balance and exerting force in movements.

During the laser-type ultra-long discus core stability training and information feedback monitoring training, the athletes stand on the balance platform of the balance training device with information feedback function in an unstable state that can shake back and forth, and combine the optimized The design is close to the characteristics of the discus strength. The discus last force device mainly consists of a circular track and a lifter. Hold the discus with your hand to practice the core strength of the super-long discus, and get into the final force preparation position. Touch the second motor switch to make the first The second motor starts, the flywheel and the chain move relative to each other, and the sliding box moves clockwise quickly on the circular track to eleven o'clock (the highest point of the circular track is twelve o'clock), and the second motor stops. At this time, the throwing arm, waist and Relevant muscle groups are fully eccentrically elongated—that is, concentric contraction for the final hard exercise. The laser speedometer tests the practice speed. The athlete pulls the sliding box to make the flywheel and the chain move oppositely. When the flywheel moves to the end of the chain, the flywheel and the chain The chain is separated, and the balance training device with information feedback function starts to work at the same time, measures the amplitude of the swing, performs quantitative processing of the information, and monitors the balance state of the athlete in real time, and converts it into an electrical signal and a signal on the crank connecting rod mechanism. The first motor is electrically connected. With the improvement of the athlete's balance ability, the balance training device tends to be balanced during the athlete's practice. The balance training device sends out an electrical signal to start the first motor, which drives the connecting rod to reciprocate, and then realizes the elevator and the circular track. swings to add new levels of difficulty to the exercises. The setting of the pressure sensor can display the speed curve of the athlete's last force, and then effectively monitor the entire sports technology process in real time.
