If you’re not familiar with the sport of Alpine Skiing, it is essentially a race down a snowy mountain with continuous changes of direction around poles and on skis of course. From technical to speed disciplines (SL, GS, SG & DH), gates get further apart, skis get longer and speeds get much faster. In my opinion, this makes it an agility-based sport. As recent definitions of agility seem to include the “response to an external stimulus” aspect alongside the “whole body change of direction” I’d understand if you were to argue against me. (Again if you’re not familiar with the sport, athletes do inspect the course before the race so they have the opportunity to memorise and visualize each turn, thus you’d think most movements are preplanned.) However as athletes speed toward each gate, I’d argue they are still adjusting to what’s in front of them, it’s unlikely that every turn will be perfect, snow moves, you can lose balance for a split second or make a mistake and thus reaction speed is also a huge key to their change of direction ability when competing or even training for that matter.
