Abstract
The purpose of this study was to objectively identify differences between conventional parallel skiing (side-skidding) and carving (no side-skidding) with regard to selected movement actions of the upper body and their influences on movement stability. Comparison of the two skiing styles is approached by a set of quantifiable technique metrics (lateral, horizontal and rotational movement of the upper body), extracted as principal components (PCs) from whole-body wearable sensor data of highly experienced skiers (n=20). Stability was quantified through normalized jerk scores. Carving involved increased angulation of the hip in the transition phase, a more posterior body posture over the whole skiing turn cycle, and less upper body rotation in the steering phase. In all technique elements carving was more stable (lower jerk score) compared to parallel ski steering.
