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.

When conducting super-long discus core stability strength training and sports information feedback monitoring training, 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, left and right, and combine the optimized design The final force device of the discus, which is close to the characteristics of the discus strength, is mainly composed 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 preparation position for the final force. Touch the second motor switch to make the second The motor starts, the flywheel and the chain move relative to each other, 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), the second motor stops, and the athlete pulls the sliding box to make the flywheel and the chain Reverse relative movement, when the flywheel moves to the end of the chain, the flywheel is separated from the chain. At this time, the throwing arm, waist and related muscle groups are fully eccentrically elongated—that is, concentric contraction for the final hard exercise, with information feedback at the same time The functional balance training device starts to work, measures the amplitude of the swing, quantifies the information, and converts it into an electrical signal to be electrically connected to the first motor on the crank linkage mechanism. With the improvement of the athlete's balance ability, the balance training device When athletes tend to balance during practice, the balance training device sends out an electric signal, starts the first motor, drives the connecting rod to reciprocate, and then realizes the swing of the lifter and the circular track to increase the difficulty of new exercises. The setting of the pressure sensor can display the athletes The speed curve of the final force, and then effectively monitor the entire movement process in real time.
