Abstract

Disclosed is a digital device for training strength on a curve in short track speed skating. The device comprises a sensor base framework, a trapezoid cuboid steel frame, a bevel steel bracket, a disc treading transmission system installed in an apparatus framework formed by a flat fork frame, a wind resistance rotating disc transmission system, a walking wheel system, a pressure sensor, a shaft rotating photoelectric switch code disc, a photoelectric switch sensor, a data acquisition power supply, a camera and a laptop. In simulation of treadle training on a curve, an athlete stands on the edge of a rotating disc in a curve posture, with his/her body leaning leftward, shoulders and waist pressing against a sliding rest arm, left hand holding a connecting rod on the central portion of a pole, and two leg crossing and treading rightward. The rotating disc is treaded to rotate anticlockwise, and the rotating force is transmitted to a wind resistance rotating disc to generate whirl wind resistance. A rotating speed optical code disc system of a main shaft records the rotating speed signal of the main shaft and sends the signal to the laptop to simulate treading speed signal data. The motion pressure of the athlete treading on the disc is sent to the laptop by a sensor, which generates a pressure signal, to simulate motion pressure periodical curve signal data. The camera taking video image of the entire training process, and the video image, the simulated treading speed curve and the motion pressure periodical curve signal data are displayed and recorded on the laptop. The treading resistance source automatically tracks the change of the muscle strength of the athlete, and athlete motion parameters such as ice treading speed and strength, frequency, amplitude and power are digitally displayed and recorded. The training effect can be evaluated based on the data. The device can be used for innovating training method and improving skating score.
