Illustration of beginner's snowboarding entry skills

The 2022 Beijing Winter Olympics has a new understanding of domestic ice and snow sports, and snowboarding originated in the United States in the mid-1960s, and is related to skateboarding and surfing. Many beginners have doubts about skiing, so what are the entry skills of snowboarding?

Straight-line sliding is straight-line sliding from the beginning, which looks very simple, but many beginners fall badly when trying straight-line sliding, sometimes leaning, sometimes leaning forward and leaning back. Next, the little thing will analyze the most basic skills about human balance in straight sliding.

Take the balance when people stand as an example. I believe everyone knows or can intuitively feel that only when the projection of the position of the center of mass on the plane is just within the corresponding range of the soles of the feet can people keep balance, so an important and obvious factor to keep balance is to avoid excessive tilt. However, when we slide in the snow, because of the small friction resistance, it is easy to control when the body is disturbed and becomes no longer upright, which leads to a large angle tilt and eventually falls. In order to better grasp the balance of our body when we slide forward, we need to lean forward slightly so that the center is close to the front foot, which can effectively reduce accidents such as falling or overturning.

Braking comes with braking, and braking has become a technical job on a smooth and inclined slide. Braking is obviously to increase the resistance when moving. Going back to the previous discussion about walking resistance in snow, we know that if we want to increase walking resistance in snow, we need to exert greater pressure on snow to make it obviously deformed. In snowboarding, braking is achieved by turning the snowboard to one side and tilting it slightly to reduce its contact area with snow. In this process, a major problem that can not be ignored is the balance of the body, because in this process, athletes need to take the initiative to tilt their bodies and skis properly, so once the range is not properly grasped, it will easily lead to accidents such as falls.

Turning on the entry skills is relatively difficult. People who have practiced skateboarding may be familiar with it. In snowboarding, if you want to turn, you need toes and heels to adjust your strength. Simply put, if you want to turn to that side, you lean slightly to that side. The physical principle behind it is that when the human body leans to a certain side, because the human body itself has a certain moving speed, at this time, a part of the component of gravity provides a centripetal force for the rotation of the human body, so that the human body can rotate around an axis. The relationship between the centripetal force provided by the component of gravity and the rotation radius can be described by a simple formula:

If the tilt angle is large or the movement speed is small, it can be seen from the above formula that the rotation radius will be small, and at this time, the athlete will rotate around a small circle, which will easily lead to body imbalance. Therefore, if you want to turn better, you need to have a certain speed, control your own inclination and grasp your own balance.
