摘　　要：通过对世界花样滑冰大奖赛国内外优秀运动员跳跃动作的技术录像解析,获得的起跳时水平速度、空中水平位移、起跳时垂直速度、腾空高度、空停时间、腾起角、关节角度等参数,并把我国优秀运动员与国外优秀运动员作比较,结果发现我国运动员起跳时水平速度与国外优秀选手还有差距,需提高滑行技术和蹬冰力量;我国部分运动员腾起角偏大,在提高水平速度的同时,人体重心腾起角应逐渐减小;助滑末期运动员支撑腿应积极屈膝,充分后引浮腿,起跳时支撑腿应积极蹬伸,形成"小摆臂,早收臂".By the comparative analysis of female figure-skating jumping movements of Chinese players and their distinguished foreign counterpart, and using a series of parameters such as the jumping parallel speed, the parallel movement in the air, the jumping vertical speed, the jumping height altitude, the staying time in the air, the gravity jumping angel and the joint angel are obtained. The parameters are primarily derived from the technical analysis of video data on the international Grand Prix of Figure Skating. It concludes some instructive findings： compared to the top player abroad, Chinese players are in general fall short of skipping level speed and therefore need to improve gliding technique and leg power; some Chinese players＇ gravity jumping angels are relatively large and should be smaller when player gets a high level speed; the supporting leg of the player should bent sufficiently at the final point of gliding-preparing while the supporting leg should be at full stretch when player starts to jump with the concurrent performing of ＂small dangling arms and early pulling arms＂ movement.
