In-Competition Severe Injury Events in Elite Alpine Ski Racing from 1997 to 2020: The Case of the Austrian Ski Team

Background To increase safety in elite alpine ski racing Injury Surveillance Systems were implemented and preventive measures introduced. However, studies analysing the change in athletes' injury risk by controlling for their exposure are still scarce. Objectives This study aimed to describe and analyse the risk of in-competition severe injury events (SIEcomp) in elite alpine ski racing. Methods Data recorded in the Austrian Ski Federation's Injury Surveillance System were used to analyse the SIEcomp incidence. Information on athletes' competition exposure was obtained from the official website of the International Ski Federation. In 23 seasons, 2333 skier seasons were recorded for the Austrian Ski Team. Within a total of 114,531 runs 169 SIEcomp occurred. Generalised Estimating Equation for Poisson Regressions were applied. Results The SIEcomp incidence per 1000 runs was 1.48 [95% confidence interval (CI) 1.26-1.73] for elite alpine ski racers and 2.21 (95% CI 1.79-2.75) for the subgroup of World Cup racers. A significant sex difference was detected for the subgroup of junior racers with a higher risk for female athletes [risk ratio (RR): 2.97, 95% CI 1.46-6.05]. Between the seasons of 1997 and 2020, the seasonal SIEcomp incidence increased by a factor of 2.67 for elite alpine ski racers and 3.53 for World Cup racers. Downhill (2.75, 95% CI 2.18-3.47) had the highest SIEcomp incidence, followed by super-G (1.94, 95% CI 1.30-2.88), giant slalom (1.40, 95% CI 1.06-1.85), and slalom (0.64, 95% CI 0.43-0.96). Conclusion Although many preventive measures have been implemented in elite alpine ski racing, the risk of SIEcomp has increased over the last two decades.

Automated summary

This study analyzed the risk of in-competition severe injury events (SIEcomp) in elite alpine ski racing and found that female athletes had a higher risk. The study also showed an increasing trend in SIEcomp risk over the past two decades.
