Ant Manor Title: Why do short-track speed skaters touch the ground with their hands when they turn?
A. Prevent falling
B. Smooth the scratches on the ice surface
Short track speed skating is a project of the 2022 Beijing Winter Olympics, in addition to the Beijing Winter Olympics, the mainland has won a total of 13 gold medals in the history of the Winter Olympic Games, of which 10 are from the short track speed skating project, Wang Meng also said: "The closest project we are to the gold medal is short track speed skating", it can be seen that the Chinese team attaches great importance to the short track speed skating project, this year's Beijing Winter Olympics Chinese team also appeared like Ren Ziwei, Wu Dajing, Li Wenlong and other outstanding athletes, in the short track speed skating competition, We often see athletes holding hands on the ground during competitions, why is that?
In fact, short-track speed skaters generally appear when turning in circles with their hands, this is because the speed of short-track speed skaters is generally very fast, and when turning, athletes are equivalent to doing circumferential exercises, at this time athletes will have a centrifugal trend, in order to prevent falling out, athletes need a lot of centripetal force, so short-track speed skaters will tilt their bodies to increase centripetal force when turning, so as to avoid being thrown off the track, while holding the ground with their hands can also support the body, not to let themselves fall, And you can also give yourself an acceleration when turning.
In summary, the answer to this issue of Ant Manor is "prevent falling".
