compared with tripping or missteps among young and middle-aged adults. 3 Slipping while walking commonly occurs at heel contact when insufficient friction forces result in the foot translating forward over the support surface, and a recovery response is often needed to prevent a fall. This response often

variations in opposing forces from snow-ski friction, air drag, and gravity across different terrains. By contrast, work rate and the fractional utilization of WR max provide a more universal understanding on how skiers distribute power during training and competition.
