| 摘 要： | 本文运用文献资料法和逻辑分析法从助跑、起跳、过杆三个技术环节深入分析优秀背越式跳高运动员技术的“三快”特点。得出以下结论：助跑阶段起跳脚着地瞬间较高的质心水平速度和最后两步良好的助跑节奏是取得成功的必要条件。起跳快表现为起跳脚蹬伸速度快，摆臂摆腿快且节奏明显。过杆快体现在头肩开始过杆时展体快，头肩过杆后挺髋快、臀部过杆后收腹举腿快。

| Abstract: | By means of literature reviews and logical analysis,the three major techniques of take-off foot landing, take-off and clearance are analyzed in detail so as to study the speediness characteristics of excellent back flop highjump athletes' techniques. The following characteristics are therefore concluded after study. A high horizontal velocity of center of mass at the instant of the take-off foot landing together with a good approach rhythm in the last two steps is critical for success. Quick take-off means an instant extension of the take-off foot and the rapid swinging of the arms and the legs with obvious rhythm. Quick clearance means extending upper body rapidly while the head and the shoulder are passing over the bar. Besides it needs a quick pelvis lifting,and when the hip and thighs have cleared the bar,the hip should be flexed rapidly and the lower leg should thrust actively upwards. |
