HOW TO REDUCE AIR RESISTANCE IN SPEED SKATING¹⁾

This paper mainly introduces how speed skaters reduce air resistance in competition. Firstly, the air resistance of speed skater is introduced, including friction resistance and differential pressure resistance. Then, wind tunnel experiments and computer simulations are carried out to illustrate how speed skaters reduce drag through clothing, posture and alignment. The research on drag reduction in speed skating can provide technical support for winter olympic athletes and help to improve competition results.
