摘　　要：目的:通过对5名残疾人站姿高山滑雪运动员大回转技术动作进行分析,探寻大回转项目最佳滑行路线。方法:使用一台大疆无人机(Air 2S)空中定点采集运动员大回转技术滑行视频,根据视频解析所得数据分析运动员滑行过程中速度变化、转弯半径大小、转向点距旗门的垂直距离并结合瞬时滑行性能参数分析影响运动员比赛成绩的因素。结果:速度的保持与恢复能力较强的运动员比赛成绩较好;转弯半径过小会造成运动员在转弯处速度骤降从而增加比赛用时;转向点距旗门过近或过远均会降低运动员的运动成绩。结论:(1)运动员在滑行过程中应注意速度的保持和恢复。(2)运动员应当通过控制转弯半径的大小来减少转弯阶段时间的损耗。(3)运动员在转向点距旗门适中的垂直距离有助于减小转弯时速度的损失。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 2 S)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.
