Pressure Control Movements

The ability to manage, control and manipulate pressure is often describe as the most difficult skill to muster of skiing. Effective pressure control requires the constant action of muscles and use of specific movements to moderate forces from foot to foot, along the length of the skis, and between the skis and the snow. The amount of pressure that is applied to the skis can be controlled by repositioning the center of mass or by changing turn radius, speed, amount of bend of your joints, edge angle and weight distribution.

Fore and aft movements control pressure along the length of the feet and skis. The deliberate application of pressure to the front, middle or back of the feet allows you to use ski design to aid in turning and edging.

Turn radius in the other words size of the turn. In skiing we talk about short radius, medium radius and long radius turns. Short radius turns create more pressure that the long ones.

Speed also effects pressure during the turn: the greater the speed the greater the pressure.

Flexion and extension of the skiing joints, affect pressure. The speed at which you flex and extend can define the amount and duration of pressure on your skis. If you body accelerates downward from a tall position quickly, pressure on the skis temporary decreases.

When the flexing is stopped pressure increases.

立刃之外, 能直接控制的就是伸腿收腿了

Fore/Aft控制压力分布
Turn radius是立刃和Steering/Pivoting的结果
Speed不可直接控制

剩下的就是蹬腿了

这个真的很难，pressure 和 edging 分不开，两个都不好练。

是地, 讲压力控制意义不大, 要靠个人在Mileage中慢慢体会了

pressure control放最后面，看来是最难的

没有各个关节的MOBILITY，就没PC。
大家还是先MOBILE了吧

SNOWRIDER给大家把脉，基本全是PARK AND RIDE，
谈何PC？

早蹬腿早升天

微言大义，概莫如是

”蹬“者，非蹬直也！

立刃增，则离心力增；离心力增，则压力增；压力增，欲抗之自不可不蹬。是故”蹬“为果，实非因也！”早蹬腿“为我所求，非我所为也！

“可”早蹬腿“则”早升天？然也；“欲”早升天，”必先“早蹬腿？大谬不然！

三无（无立刃无离心力无压力）而早蹬腿者，则或popup或失却平衡，板之将覆，安有压力？舍本逐末，升天无路也！

是故，大侠金句，皆有真意，念念不忘，必有回响，如若不灵，尔乃蛮夷。呜呼！阿门！

猫兄，不是看到古文俺们就都当九阴真经供起来的， 俺高考古文部分相当厉害的，虽然不能用甲骨文写高考作文，
但整个四书五经看个红楼梦啥的没问题。。。。。

老视频翻出来说说，从开头到3分钟出场能观察到的有加拿大，日本，美国，意大利。
我感觉貌似是加拿大出弯前用PRESSURE用的最狠，直接利用反弹力换刃，几乎要腾空了，板刃换到新弯碰到雪面的时候已经有相当大的角度。相反美国用的最柔和，出弯和入弯看起来非常平顺。
