Abstract
The anthropometric and aerodynamic conditions are among the important factors that decide performance in downhill ski races. This paper combines a theoretical approach with input data from wind tunnel experiments to estimate the influence of selected variables on speed in skiing. The variables of interest are the mass of the athlete and the aerodynamic forces, drag and lift. Based on the findings of the study, an anthropometric code number (ACN) is introduced. This ACN value is a combination of the mass of the skier, the coefficient of drag, and the greatest projected area the athlete exposes to the airflow. It seems that the ACN is a valid, easy-to-calculate number in order to compare test results from wind tunnel experiments. Verf.-Referat
