关于WEDGE TURN

bullpower

老大说应该讨论讨论八字转弯。
我以前觉得八字转弯是我的特长，
老早以前有次JS说过，八字转好了也不容易，我其实还不是特别在乎
现在才意识到，我可能目前才意识到了JS当时的体会。。。。

我想先问问大家滑8字的时候都想的是什么，GOAL 是什么
你教别人8字的时候，你的目的和重点是什么

先说说自己，就是觉得稳就行，能去各种道，总滑八字丢人，别人都平行了。。。。
其实这都错了，做了些调查，

首先八字是什么：
Snowplow turns should be used as a teaching tool to develop the
skier’s confidence in relation to balance. The skier will be able
to bring the skis parallel once they have acquired better lateral
balance and more stability on the downhill ski.
所以同意IntoTheWind说的八字是一个DRILL.

所有DRILL  做标准了都不容易。

在看看下面的要求，所有都让我汗颜。。。。。。。


Exploration 1 - Bronze
Pre-requisites: None

Goal: Executes linked rhythmical snowplow turns

Evaluation terrain: Easiest terrain

Overview:
At the beginner stage, the key element is to build the skier’s
confidence in order to gradually develop autonomy. To achieve
this, they have to develop balance and be able to stop.
Create mobility games on one or two skis that will help develop
balance over both skis.

Development Strategies:
On flat terrain, practice a breaking plow followed by a straight
run, followed by a breaking plow, and so on. Repeat the exercise
for as long as possible without turning. The goal is to develop the
pivoting of both skis simultaneously to create the wedge.
Using cones or ski poles set up an easy course. Get students to
ski around the cones or poles to develop consistent turning on
both sides.

On easy terrain, use a serpentine approach (narrow turns in the
fall line).

Exploration 2 – Silver
Pre-requisites: Executes linked rhythmical snowplow turns

Goal: Executes part of the turn with skis in parallel position
Evaluation Terrain:
Overview:
Snowplow turns should be used as a teaching tool to develop the
skier’s confidence in relation to balance. The skier will be able
to bring the skis parallel once they have acquired better lateral
balance and more stability on the downhill ski.

To develop balance, vary the turns according to the terrain.
Remember that mobility is an essential component of balance.

Development Strategies:
Ask students to jump twice between turns using ankles, knees
and hips in order to get them to jump as high as they can. This
will help develop mobility in all three joints.

Choose a run with varied choice of terrain (flat, steep…). Ask
the skiers to follow you and try to keep the same speed while
changing the turn shape to adapt to the different terrain.

The goal
is to make the students aware of the relationship between speed,
terrain and turn shape.
At the end of a snowplow turn, while sliding the inside ski parallel
to the outside ski, execute a diagonal side slip.

Exploration 3 - Gold
Pre-requisites: Executes part of the turn with skis in parallel
position on green terrain
Goal: Executes basic parallel turns (no wedge)
Evaluation Terrain:
Overview:
To achieve this objective, the skier will need to acquire pivoting
skills while demonstrating lateral balance and pressure over the
outside ski.

In order to do this, the skier has to develop the skill of turning both
legs, which will make it easier to initiate the turn with the lower
body.

Demonstrate this by breaking down simple exercises such
as a situational wedge or a single turn. You can also challenge the
skier by getting them to Starting in the fall line, execute the last segment of a turn while
increasing the edge angle using angulation of the ankles, knees
and hips.

The skier has to be able to change direction while keeping
the skis parallel as much as possible in a variety of situations. This
type of skiing mileage will enable the skier to achieve the goal.
Note: You will notice that the students will discover how edging
works without mentioning it.

Development Strategies:
While making snowplow turns, ask the skier to gently tap the
inside ski. This will help develop lateral balance and naturally help
the skis to become parallel throughout the turn.
Choose a safe place on an appropriate terrain. Ask the students to
complete each turn as much as they can and finish with the skis
pointing uphill. This will help develop pivoting and edging skills for
good turn completion and speed control.

Starting in the fall line, execute the last segment of a turn while
increasing the edge angle using angulation of the ankles, knees
and hips.

看了划线的重点，俺觉得俺八字没及格。
所有平行滑里的缺点，在这里都体现出来了。。。。

都别拦着， 我要散功重练乐。。。。

牛博士，你这么牛逼的论文不打算收费吗？

随然绝大多数的人都不能滑好一个完美的八字，但八字却留给大多数人一个非常深的阴影。绝大多数的中高水平滑雪者还是会出现多少的八字，或者单腿推板（八字的后遗症）。

KuoiGuaBoarder

嗯，我也发现我时常有八字，一不注意就会出现，牛博士你要帮帮我

bullpower

总之8字儿时就应该有如下意识：
1。mobility in hip knees ankles - 僵尸滑的进来排队，我领男一号了。
2. turn with lower body, and turn both legs simoutaneously - A 腿/上身转的进来排队，我排第一个了
3. outside ski dominant - 内脚承重的进来排队,占个位儿先
4. centred stance - 后坐的排队
5. complete and rounded turns - 转不圆，速度控制不住的进来排队
6. pivoting - 蘑菇滑不好的进来排队，我也排第一个了

世界杯上还有全程八字的呢

其实平行弯里出现八字，是因为八字练得不够，八字过关了，平行也就没有八字了，这叫相生相克，物极必反

其实换刃也是这个道理，都说pop过时了，其实pop练得不过关的话，racer style一样没戏

再比如说，新手滑之字你说人家扭板，高手扭板你就说那是控速，新手打滑你说那叫莎车，高手打滑你就说是新月弯，新手你说人家内脚承重，高手你就叫压力控制了，甚至重心后座还是racer的核心技术呢

所以，把脉挑毛病，练drill什么的都是揠苗助长，里程数才是王道！

俺脚的人家高手能做到想不怎么滑就能不怎么滑
但俺不行
