ABSTRACT

Several factors affect performance in alpine skiing. While the skier's anthropometry and physiology (heart dimensions, aerobic and anaerobic power, lower-limb power, body composition [1–2]), the biomechanic and kinematic factors (speed, friction, acceleration [3–4]), and the technicalenvironmental factors (wax, temperature, snow characteristics) have already been investigated, the skier's trajectories during an actual run have never been analyzed by quantitative testing. Analyses are most often performed in laboratory setting, where the testing conditions cannot perfectly reproduce the real conditions.
