Youth alpine ski racing head injuries remain a significant safety concern, but current safety requirements arebased on adult users, rather than children. As a result, crash tests or studies may be less specific when it comesto the biomechanical characteristics and impact patterns of children and adolescents.This research was born from this uncertainty and presents a new approach to estimating head impact velocityfrom video analysis of on-snow crashes in competitive youth skiing. Differing from previous methods relianton geometric assumptions or fixed-camera projections, the new approach derives velocity from smoothedframe-by-frame derivatives of the head path of the skier, allowing for robust analysis under uncontrolled outdoorsettings.The model was confirmed in in vivo snowfield tests using GPS-based velocity measurement and altitude profilingand exhibited greater accuracy than literature-simplified models.This method was subsequently applied to video recordings of 6- to 16-year-old skiers, allowing to measureimpact velocities and the anatomical site of impacts. The resulting heatmaps show frequency, intensity, andseverity of head impacts, providing discipline- and gender-specific trends.These findings highlight the need for new helmet test criteria and design strategies specifically targeting youngathletes, with the potential to improve safety outcomes in young alpine ski racing.
