Alpine Skiing Common Term Analysis

White snow, a skateboard, where you slide like an elf, this is your fantasy alpine skiing? If you want to ski in high mountains, you don’t have to recognize it as an elf. It’s estimated that you’re swollen, so knowledge is critical. With knowledge, you have the right practice to enjoy safety and joy while skiing.

Gravity: The weight of a skier can be roughly understood as gravity. The conversion of gravity weight ratio between two snowboards (referred to as gravity conversion) can also be understood as the conversion of weight.

Center of gravity: refers to the role of the body's total gravity. Its direction is toward the center of the earth. When the body is standing still, the position of the center of gravity is generally 7 cm in front of the third sacral vertebra. The center of gravity of the female is slightly lower than that of the male. If the human body is understood to be a vertical object with left, right, front, and back symmetry, the center of gravity must be on the center line of the symmetrical section of the left, right, and back. The center of gravity is in skiing, sometimes in the body, sometimes in vitro. The movement direction of the center of gravity in the ski movement is multidimensional, ie, the synthesis of front, rear, left, right, and up and down movements.

Center of gravity exchange: Generally refers to the change of weight on the left and right sides during skiing.

Center of gravity projection: Generally refers to the point where the center of gravity connects with the center of the earth through the snow.

Load or load: Generally refers to the snowboard (or weight-bearing leg, weight-bearing foot) that bears the main weight.

Force (Pressure): Generally refers to the pressure exerted by gravity or the combined force of gravity and intramuscular force on the snowboard (legs, feet).

Supporting area: generally refers to the position of the snowboard on the snow surface and the imaginary stable area formed by the board type and the board position (sometimes considering the support of the ski poles).

Roll-off line: A complete line of a ball rolling from the top of the mountain to the downhill and down the hill without changing the running direction. The roll-off line is perpendicular to the map contour line (drop line).

Downhill: From the hillside to the hillside, it slides straight down the rolling line.

Active board: The ski that plays a dominant role during the ski turn, that is, the heavy snowboard, usually the outer snow board or the mountain board.

Driven plate: The ski that can't play a leading role in the ski turning process, that is, the snowboard that is small or not heavy-loaded, usually the inner snow board or the hill board.
