摘　　要：该文目的是使自由式滑雪空中技巧的技术监测体系更加健全,确定评估诊断标准对项目成败的重要性,应用平面定点摄影法,对中国自由式滑雪空中技术选手进行了运动学参数的测定,并对其进行了相关性研究。该文发现,出台技术的技术敏感判定标准有:重心出台速度、踝关节角、髋膝关节夹角等。其中出台垂直速度和滑行距离是空中重心垂直高度影响因素较大的敏感诊断指标,而起跳时重心下落速度、起跳速度、起跳瞬间重心出台水平速度等是影响落地成败的敏感诊断指标。The purpose of this paper is to improve the technical monitoring system of our country's freestyle skiing aerial techniquesand to determine the importance of diagnostic criteria to the success or failure of the event.Applying the plane fixationphotographymethod,the kinematic parameters of Chinese freestyle skiing aerial technique competitors were measured and correlated.It was found that the technique-sensitive determinationcriteria of the presentation technique are:the center of gravity speed,ankle joint angle,hip-knee angle,and so on.Among them,the presentation vertical speed and the gliding distance are the sensitive diagnostic indexes thatthe vertical height of the center of gravity in the airhas a large influence on the factors,whilethe falling speed of the center of gravityat the time of jumping,the speed of jumping and the horizontal speed of the center of gravity presentation at the moment of jumping are the sensitive diagnostic indexes that affect the success or failure of the landing.
