抄一点书如下:
All of the best coaches and instructors I know teach foot movements before refining technique with other parts of the body.
If your feet are not working first, nothing you do with the upper body will make you an expert skier.
Foot movements in ski boots cause the ankle to react. The ankle then puts pressure on the sides of boot. The side pressure stabilizes the ski and keeps it on a consistent edge. The ankle controls ski stability through the ski boot.
Foot movements start a reaction all the way up the body. The kinetic chain is a movement chain, starting at one end and transferring to the other. It is a series of actions or changes that reverberate though the body, initiated by a single primary or starter movement. It is particularly relevant when the primary movement is at the base of support or balance - the foot.
这就是HH的Kinetic chain。
就俄所涉猎的范围,这个论述,的确高度概括了所有好的skiing。ron lemaster有一个形象的比喻,说你的ski boots就是网球拍的拍柄,是控制你的skiing的中心部位。
这段论述也提示了一个明确的方法,从哪里开始,到哪里结束:
由脚与boots的关系开始,到上身做出正确的平衡动作结束。
c说要上下身分离,turning effort leading by the lower body,是相对笼统的论述,也不涉及方法,却提供了非常明确的纲领性界定:滑雪是下半身运动,下半身决定上半身。
下半身主动,先动,上半身被动,随动,铁打的原则。任何有悖此项原则的,都行进在错误的道路上。
所以,不看好入风大侠这一楼的市场前景。 |
