How to control the speed when analyzing skiing.
The most direct way to slow down is to do a "speed check". The name seems to be quite tall, but it is actually kicking the back foot and letting the board brake sideways.

This action can be used in various sliding States. For example, when the toes are crossed or carved, kick the back foot to the rear, bend your knees to lower the center of gravity, and make the center of gravity move properly between your feet. Keep your body twisted. At this time, the sliding state is very close to the push slope of the toe edge. When the speed slows down, straighten the board and straighten your body, that is, kick your back foot backwards. The whole body returns to the normal sliding posture.

If the heel blades are crossed, the back foot should be kicked forward. If you are lying flat, you can kick back and forth.

However, it should be noted that this action is not used for turning, and there is no process of changing the blade. Kicking the back foot is to kick the board in a short time, but then kick the board back and return to the original sliding posture.

Deceleration, as the name implies, is a one-time deceleration, mainly by braking. Single-board cross-board snow rubbing, double-board plow brake and parallel side brake HockeyStop (also translated as ice hockey brake), and some alternative brakes, such as hip brake head brake and face brake. Another deceleration scheme is to slide uphill and convert kinetic energy into potential energy.

Control the speed in a relatively uniform range. I think this is the most concerned issue of this theme. For almost all taxiing modes, the speed can be controlled by choosing the path (controlling the shape of the curve), for example, each curve slides a little more uphill, or slides a little more horizontally when changing curves. Those with strong technical ability can flatten the curve deformation, for example, forcing on the top of the arc (carbine) or twisting hard (rubbing snow), and control the acceleration process by reducing the time when the snowboard points to the rolling line. When topographic restrictions are not applicable, technical actions can be adjusted, such as rubbing more at the end of each bend, or controlling the speed.
