外勾型跳跃这种类型跳比3字类型跳更困难,原因有二: 1、跳跃的旋转方向和起跳弧线方向相反. 2、落冰更难,落冰曲线及身体的倾斜和起跳弧线相反。外勾跳的正确线痕必须和变刃线痕的主方向一致,如图2所示(与勾手跳一致)。图2: m—主方向。 g—运动员身体重心在冰上的垂直投影. C—在起跳前瞬间的起跳弧线。 d—空中飞行。 e—落冰后的落冰弧线。注释: m:正确的跳跃主方向是在变刃中,在空中飞行必须保持直线运动。 g:运动员的身体重心必须保持和变刃线痕相吻合。在起跳前瞬间,它是在点
Hook Jump This type of jump is more difficult to jump than the 3 word type for two reasons: 1. The direction of the jump is opposite to the direction of the jump arc 2. The falling ice is more difficult, the curve of the falling ice and the body’s tilt and jump arc The opposite line. The correct line mark of the outer hook jump must be the same as the main direction of the variable edge line mark, as shown in Figure 2 (consistent with the hook). Figure 2: m-main direction. g - vertical projection of the athlete’s body center of gravity on the ice C-take-off curve immediately before take-off. d-air flight. e-Ice falling ice arc. Note: m: the correct direction of the main jump in the blade, the flight must maintain a straight line in the air movement. g: Athlete’s body center of gravity must be consistent with the change of edge lines. Just before the jump, it is at the point
