滑雪正確的站法及應用

"一般人看腳、用腳就只知道一個大腳板，而對於腳是怎樣用力的卻是幌然莫知‧一個大腳板—穩—好走路，但是更複雜一點的動作如跑、跳、打功夫、滑雪等等，這個大腳板就不夠用了‧不管你練者用多大力，這個大腳板是壓不住edge的，為什麼呢？力道不對/不及‧力道是一個向量，那是說力道不只是有力量的大小同時還要包刮其用力的方向的，所以大腳板的力道向下而無法達到邊沿/edge的‧現在我們就看看怎樣有效的用腳使力。

先說我們該怎樣站法‧一般說來，在平地上我們要是“自然中正”的站的話，雙腳是“平”的而兩腳平分身體的重量‧當腳站“平”的時候，前腳掌與腳跟是平衡的而前腳掌又平均分配在大指邊的大骨頭及小指邊的小骨頭上，所以一隻腳三點、兩隻腳六點是平均分配的支持我們身體的重量，而我們的身體此時也只能“自然中正”的站著。

再說我們該怎樣用力‧要用內沿/inside edge的話，我們的力道要用在大骨頭及腳跟的那條線上(腳板心內側)，反之，要用外沿/outside edge的話，我們的力道要用在小骨頭及腳跟的那條線上(外腳刀)‧但是我們怎樣才能把力道送到腳的兩邊呢？只有歪身體而用重量來壓‧要是練者保持一致的壓力而環遊兩腳的外側，舉例，從壓左邊的edges開始，身體/屁股向左歪，然後重心向前壓腳掌，再轉到右邊壓右邊的edges，再轉到腳跟，週而復始，做一個方向再做反方向，那就是“旋股”的練習了‧旋股是一個用重心來壓腳沿的練習‧做的對的話，力量在兩腳的邊沿轉，屁股的轉動是圓的，而頭不動‧但是，頭連身，身體在動，頭怎樣不動法？視野/眼前所見景像不變，神哉。

Thanks for your kind explanation.

Seems this drill practices how to allocate the body weight to the 6 points (兩隻腳六點) through a circle (旋). It is also in line with the fore-aft balance movement. Ultimately, the diagonal movement will be strengthened. Good drill

Well, 兩隻腳六點 is referenced to a flat ground; nevertheless, if we hold the heels on the ground while we skiing (except in powder skiing), we'd be "backseated." As the hill tilts away, to make our body perpendicular to the slope, we need to stand on the balls of foot and the heel would rise/be suspended, and we become unstable, so we need to find another place to replace its/heel function, where we've found it at where shin contacts the boot-tongue, or "shin-contact"; that's to said, proper skiing stance is on balanced "balls of foot" and the shin-contact. That's the 兩隻腳六點 for skiing.

BTW, I think we may open a new thread to have further discussion if you don't mind.

Not a bad idea, I think that knowing how to stand properly is the foundation on how to maintain balance over the skis, so here we are.

I see but have a difference. When I start a turn, I have applied your suggested approach - proper skiing stance is on balanced "balls of foot" and the shin-contact. However, when I finish the turn (after the fall line) I used to shift the contact to my heels instead. Perhaps, it may be different systems

Well, at the bottom of a turn/after the fall-line, the resultant force generated by the gravity and the centrifugal force/離心力 is at its max, so if you don't take measure to counter it, the resultant force would likely force you into the heel-contact positions, and you'd be backseated. It is not a different system's problem but a problem of physics. If you use "shin-contact," (in fact, the steeper the slope, the more shin contact pressure, so the heels are totally suspended,) you may eliminate this backseat.

Thanks

You probably haven't figured out, by using the shin-contact, you are not just found a nice place to rest your thighs, but also elevate your BoS about a foot plus; that's to say, you also have lowered your CoG about a foot, so it is more stable thus more maneuverable than "cuff-neutral" stance. Some modern carvers advocate "cuff-neutral" stance for carving, but I feel that they haven't fully utilized their $600+ fancy ski boots investment.

...by using the shin-contact...you also have lowered your CoG...

Agree and thanks!
