A study looked at the daily occurrence of injuries and illness from reports of all National Olympic Committee (NOC) medical teams and by the Sochi 2014 medical staff. The statistics revealed 8% of Sochi 2014 medical staff reported athletes incurred at least one injury or illness, while 12% of athletes reported at least one injury or illness to the NOC.
The percentage of athletes injured was highest in aerial skiing, snowboard slopestyle, snowboard cross, slopestyle skiing, halfpipe skiing, moguls skiing, alpine skiing, and snowboard halfpipe. Thirty-nine percent of the injuries were expected to prevent the athlete from participating in competition or training.
Women suffered 50% more illnesses than men. The rate of illness was highest in skeleton, short track, curling, cross-country skiing, figure skating, bobsleigh and aerial skiing.
