火鸟大侠V5。 轴转太高大上了，无pivoting不双板。
楼主定义轴转为腿部在髋关节内的独立旋转动作。请教 这个出处来自哪里？偶在红宝书中找到如下。没有明确
Pivoting
Pivoting is the ability to utilize the legs and feet to help guide the skis in a specific direction.
Whether the turns are carved or skidded, the lower body leads the turning effort.
Pivoting and direction change
With the upper body facing the direction of travel, turning the legs in the hip sockets creates a
steering angle. This, combined with ski sidecut, deflects the skier in their arc. Pivoting is seen in
the relationship between the upper and lower body.
Pivoting and balance
The ability to guide the skis on their path without relying on hip or upper body rotation will help
a skier maintain balance by keeping the body over the outside ski. From the hips down there is
less mass than in the torso, so changing direction with the lower body is quicker and lets the
COM move in a smoother trajectory.
Pivoting and edging
Upper/lower body separation enables a skier to balance on their edges through angulation.
Turning the femur in the hip socket allows the hip joint to be more mobile laterally to the inside
of the turn, helping to balance on the edges.
Pivoting and rotation
Turning the hips or the upper body before the legs at any part of the turn is called rotation. At the
top of the arc (phase 2) this could be caused by a rushed weight transfer (timing and pressure
control) or an imbalance from phase 1. Through the bottom of the arc (phase 3 into 1) it may be
caused by poor steering mechanics or a loss of control of angular momentum.
另外，偶赶脚还是要讲清主动和被动的区别，比如
Upper/lower body separation results from an active pivoting of the legs beneath the skier.
有些轴转是被动的，肌肉并没有发力。 容易误导初学者以为任何弯一直用力轴转。 |
