At the bottom of the Olympic aerials landing hill, where crashes are common and the term “slap back” is part of the everyday lingo, skiers spend almost as much time figuring out how to protect their heads as they do working on all those flips and spins.
“We learn how to fall,” U.S. jumper Jon Lillis said.
Elsewhere around the action-sports venue, that’s not so much the case.
Concussion dangers lurk everywhere — from the iced-over deck of the halfpipe, to the steeply pitched landings on the slopestyle course, to the careening twists and turns of the snowboardcross track, to the aerials course, where “slap back” is the term for when a skier’s head slaps backward against the snow. But at the Olympics, there are no hard-and-fast rules regarding who diagnoses head injuries, and no hard-and-fast protocol that athletes must clear to be allowed back on the slopes after a concussion.
