我知道妳是专业选手,相信妳滑的很好,有自己练习的一套方法,其实我只是藉妳这朵鲜花来 ...
木村公宣的这段单脚外刃教学视频片段,内容是我提供给孤独的牧羊人的,属于休闲滑雪范畴。牧羊人觉得很好,就发到网上了(偶不太同意,毕竟有敏感的版权问题),没想到在这里引发了滑雪技术的热烈讨论。
据我所知,国外的现代竞速或称竞技滑雪技术,并没有全盘否定、彻底淘汰“反弓”或称“侧弓”技术即ANGULATION,而是对这门重要的新古典技术有扬有弃、去粗取精,发展出“动态反弓”(动态侧弓)概念,这正是国内职业教练和运动员应该虚心学习的细节。下面这篇国外职业教练的图文分析有助于讨论时参考。全文链接如下:http://youcanski.com/en/coaching/incline-to-win.htm
主要段落:
Dynamic Angulation
Angulation or “break at the hip” in the final phase of the turn is demonstrated here by Pallander and Nyberg (photo 3). Often considered an edging movement, angulation, in reality, just compliments inclination. It serves to maintain an edge grip when forces build up in the second part of a turn. Angulation cannot be performed effectively unless the initial edge angle is created by proper inclination. For a powerful turn exit, it is important that the outside leg stays extended until after the arc is completed. The tendency of the modern technique of using the reduced angulation and more pronounced inclination is clearly demonstrated by Maier (photo 3, frames at the last blue gate). It is worth mentioning that the angulation in modern technique is created by slight straightening movement of the torso resulting in bringing the racer’s shoulders in horizontally level position. More often than not, gross angulating movement in the hip joint is no longer needed. The amount of angulation is determined by the speed and the radius of the turn.
The above mentioned tendencies of modern technique need to be reflected in teaching the young athletes. Many juniors still ski in static, “locked” position, using excessive hip angulation. More often than not the “locked” position is unintentionally created by coaches trying to correct the “leaning in” problem by asking racers to work on more level shoulders. This approach is incorrect because, while it may cure the “leaning in”, it develops a movement pattern inconsistent with fast dynamic skiing. In fact some leaning in is often present in athlete’s skiing at the initial stages of learning the inclination. Usually “leaning in” is a result of balance deficiencies preventing proper CM projection and re-centering. The best cure for it is returning to fundamental work on developing balance and above mentioned skills as well as finding the sensations necessary for effectively using the key element of modern technique – the inclination
