Athletes at the Winter Olympics make high-flying, death-defying moves look effortless. But with little margin for error, the jumps and spins they're performing are often at least as risky as they appear.
Several athletes have already sustained injuries at the 2022 Winter Olympics in Beijing: Alpine skier Nina O’Brien broke her leg, hockey player Brianna Decker was stretchered off the ice and speed skater Park Jang-hyuk injured his hand.
According to a study by the International Olympic Committee, about 12% of almost 3,000 athletes participating in the 2018 Winter Games in PyeongChang sustained at least one injury.
