In any case, the idea of a "carved turn" on very steep terrain (at normal speeds) is quite different from carving linked "railroad tracks" on flat terrain. The engagement, pressure, and reverse-camber carving phase must start much later in the turn, when the gravitational and centrifugal forces of the turn combine to pull you "out" of the turn. Resisting these forces provides the pressure you need to bend your skis and carve. You must be much more patient, allowing these forces to develop, to carve on the steeps.
What do you do in the mean time, while you're patiently waiting? You prepare! You focus on releasing the edges to start the turn--not engaging them. You guide your skis down the hill into the turn, rather than expecting them to carve, as you allow gravity to pull you down the hill. You incline your body into the turn--it will feel like falling--which will both tip your skis and move you inside the path of your skis, where you will be in balance later, when your skis engage and carve back beneath you.
Note that these turns are "carved," in the sense that my skis pretty much travel the direction they're pointed, as opposed to being pushed sideways into a skid--even in the upper halves of the turns when they are unweighted. When the edges engage--about at the fall line (when they point straight downhill)--my skis are already tipped to a high angle, and I am inclined well inside their path, so they can carve cleanly through the middle and bottom of the turn. In the top half of the turn, my skis are light on the snow and I'm guiding them actively along their path with my legs. In the bottom half of the turns, it is easy to get enough pressure and edge angle to bend the skis into deep arcs, so they can continue to carve the same tight radius I guided them into in the upper half.
While my skis are very much "unweighted" at the top of the turn, these are hardly "hop turns." Hop turns begin with a quick leg extension from an edge set, momentarily increasing the pressure underfoot as you leap into the air. By contrast, in these turns there is very little "up" motion through the transition, and my legs extend to their longest only as I incline through the top half of the turn. These turns end with an edge release, where my skis have rolled off the high angles of earlier in the turn and let go of the mountain, as my body crosses over and moves down the hill. Instead of the big effort of an extension (hop), these turns begin with relaxation, as I let go of the pressure of the previous turn, allowing my skis to continue to move forward beneath me, as my body continues its existing motion across the skis' path and down the hill.
所以在CSIA里面强调的三大要素(Central and Mobile stance, balance on edge, turn by lower body) 和五大神技(Stance and balance, edging, pivoting, timing and coordination, pressure control) , 在加国的滑雪理论中, 哪一个不是休闲滑雪和竞技滑雪的基础? 作者: lupo 时间: 2013-11-12 00:35
re-centering pole planting容易理解多了,是在行进方向的正前方点杖,目的是把压在后面的中心拨到前面来。
steep上为什么用blocking pole planting较多,俄的理解是重力加速度大,弯的后半截前冲力太强,转向更困难。这一点跟racing的slalom是一个道理。前面也说了,racer在slalom上用到blocking pole planting,要么是道上的旗门设置太狭促,要么是技术动作不到位,冲太大,under-steering了,需要点杖帮助转向。

blocking就是阻挡的意思。所谓blocking pole planting,是说在行进方向的侧前方点杖(侧翻手腕就为这个), ...
理解你的意思了,我將之簡化一下。
blocking pole planting : 點在舊彎行進間左右方,直接幫助變換方向轉彎。(看來這轉向比較突然性,重心沒有前後變化)
re-centering pole planting : 點在行進間左右前方,把舊彎重心由後拉回前,再進行新彎。(這轉向比較圓滑,且滑行中重心有前後變化)
