标题: 圣山技术笔记
本帖最后由 rockyroc 于 2016-2-24 00:02 编辑

圣山学校每天的晨操是我决定周末起大早去打工的主要原因。学校跟wb完全不是一回事,三级都只有限几个,四级更是珍稀山宝,轻易不得一见,不过我是纯野路子出身,一级考试都当难得的培训课上,白米糙饭对一只饿了五年的老鼠绝对是珍馐美味。只是人老真是忘事,上完课不过一天就跟水过鸭背一般,一丝儿脑子里也不剩下,只好记个笔记。分享在这儿,有兴趣的初级同雪或许也有借鉴。

事后回想起多少就记多少,拉拉杂杂,可能会很零碎,而且中英混杂,阅读起来还请包涵。

这个多少有点借鉴了lupo的日记的意思,不过水平有限我就尽量少加自己的comment。相信这个不会有版权之类的问题,目前所见,学校的教练们都蛮open and sharing,还是有点我希望的户外人的格调。

* O Frame (transition)
Starting transition by rolling downhill ski a little tiny bit earlier than uphill ski intentionally. For a very short moment, 2 legs form a O frame, rather than the popular A frame.
Basically this is to initiate a new turn by the new inside ski.
Practice on flat first. Can also try to practice making the O frame at still to promote the feeling of O frame.
Note 1: This more or less reminds me the inside ski tipping concept of PMTS.
Note 2: Don't confuse this with weight shifting. When focusing on rolling the downhill ski first, doesn't necessarily mean you are holding more weight on downhill ski. Actually the weight shifting from downhill ski to uphill ski should be still ongoing at the same time.

* Rolling Toes (transition):
To start transition, imagine to roll the downhill foot from big toe to little toe and at the same time roll uphill foot from little toe to big toe.
This is a conceptual drill for kids, to make things (transition) silly simple.
For advanced adult, I feel that it may be a good drill here to imagine to roll the downhill foot a little tiny bit but clearly earlier than the uphill foot. Sort of similar to the O Frame drill.

* Too Far
While doing the O Frame or Rolling Toes, lean way forward and then backward and then the center stance to feel the different effect.

* Blind Skiing
Ski on gentle slope with eyes closed. The point is to promote body sensation of skiing. Need a partner to help watching.

[20160213 - 0215]  

* Technic vs tactics (teaching)
Teaching is not only about Technic, but also about Tactics, i.e:
- choose different terrain
- use different turn shape
- various speed
- drills etc.  

* Slow Skiing
Find appropriate terrain, ski with normal turn shape and speed, while slow down all body movements. Count 1-5 when loading, count 5-1 when releasing.  

* Outriger
Tried this one myself before and didn't like it much, but this time felt pretty good with it.
This is to help align shoulders and hips in parallel position through the turn. It is beneficial for skier with too much hip angulation early in the turn, or too little angulation late in the turn. By holding poles out with both pole tips dragging slightly in the snow, the shoulders will match up with the terrain. A common error in doing this drill is skier will break at the waist or sit back to get both poles to contact the snow. This drill should be done balanced with hips up as skier needs to be more active staying forward since arms are to the side.   

* Tactic for 点杖后甩手
After pole plant, leave the tip of the pole on the snow, and drag the pole through the turn. A light trace should be seen.  

* Short Turn tactic
Start with hockey stop or braquage; slow down the turn part gradually, and eventually transit to short turn.  
Very firm pole plant.  
I like to add double pole plant to this tactic, which can be seen as a enhanced braquage.  

* Jim's comment
Less edging, more high c pivoting (for L2).  
Centered stance! Still see a lot sitting back. Shoulder needs to always align to the tip of binding.  
Turning by lower body needs refinement. Upper body is leaning inward when I try to add performance with edging.  
P.s Jim doesn't seem to agree with the idea of "extend your outside leg". Didn't dare to argue with the L4 ...

不错不错, 给咱这些考不上级的开开眼界。

关于闭眼练习 也说几句。

其实有很多类似的练习, 我遭受过的有: 闭一只眼滑, 闭一只眼滑大小圈, 换眼闭滑,耍金箍棒滑, 歪脖滑, 抱杖滑, 雪杖顶头上当犄角滑。

这些DRILLl很有趣, 其目的就是给你EXTERNAL CUE去BALANCE,脑子里不再想着,要干啥干啥,而是靠身体自动去调整的平衡状态。
一般红牛看到学生, 特别是成年学生, 特别是像同雪网这样猛钻研的学生, 特别是同雪网里的程序猿或挨踢学生,
都是太ANALYTICAL的性格,滑一个TURN,脑子里迸发出好几万个小火花,想着几十件事。。。这些是INTERNAL CUE.
ACQUISITION STAGE, 这些INTERNAL CUE可能根本触发不了正确的肌肉反应。
而 EXTERNAL CUE就是不让你去用大脑想该怎么滑该摆什么POSE, 你的小脑会控制身体姿态和肌肉去达到平衡。
也许会有崭新的感觉的!

[20160219-0220]

* Pole action
How/where/when to pull in pole, for pole touch.
How: only wrist movement.
Where: A small rectangle area beside ski tip, about half feet away?
When: when the body just starts up.

* Slow skiing for better turn shape

* High performance with slow skiing
Ask for edging while ski slow

这周末内容比较少。不过两个教头不约而同地都在说slow skiing,有意思。。
