Of course, aerodynamics play a huge role in skijumping and cross country skiing. It is always important for the athlete to be in an aerodynamic position, to help gain the highest possible speed in the inrum and to have a minimum of air resistance in the flight phase. The equipment and the technique of the jumper largely impact the aerodynamics and are therefore tested in a wind tunnel.

In the cross country part of the sport, the position in the wind shadow of a leading skier means a huge advantage and is therefore highly coveted. For cross country skiing, tight suits and a ducked position in descents are advantageous. Some skiers even put their poles behind there backs to be more aerodynamic.
