Abstract Objectives This study aimed to investigate air drag and lift during the in-run and flight phase of ski and snowboard slopestyle and big air, to allow more valid modeling of jumps and hence reduce injury risk. Design We present an experimental, multiple single athlete study based on wind tunnel measurements of 4 skiers and 3 snowboarders. Methods Measurements were carried out in a closed loop wind tunnel, measuring airflow speed and 3D forces acting on the athletes.
