Abstract

Abstract: To explore the best taxiing route of the great slalom event by analyzing the great slalom technical movements of five disabled standing alpine skiers. Methods: A Dajiang unmanned aerial vehicle (air 2S) was used to collect the glide video of athletes' large rotation technology at a fixed point in the air. Based onthe data obtained from video analysis, the speed change, turning radius and vertical distance between the turning point and the flag gate were analyzed, and the factors affecting athletes' competition performance were analyzed combined with instantaneous taxiing performance parameters. Results: the athletes with strong ability to maintain and recover speed achieved better results; if the turning radius is too small, the speed of athletes at the turning will drop sharply, which will increase the competition time; if the turning point is too close or too far from the flag gate, athletes' performance will decrease. Conclusion: (1) athletes should pay attention to the maintenance and recovery of speed during taxiing. (2) Athletes should control the turning radius to reduce the loss of turning time. (3) The moderate vertical distance between the turning point and the flag gate helps to reduce the loss of speed when turning.
