| dc.description.abstract | Background: No previous studies have investigated the injury incidence in individual
qualification runs vs. final runs in heats of 4 or more athletes in FIS World Cup (WC)
Snowboard Cross (SBX) and Ski Cross (SX). Objective: To investigate the injury
incidence and injury patterns in individual qualification runs vs. final runs of SBX and
SX during four seasons of the FIS WC. Methods: Injuries were recorded by the FIS
Injury Surveillance System (FIS ISS) through retrospective athlete interviews at the end
of four WC seasons (2006-2010). Time-loss injuries occurring during qualification runs
and final runs of SBX and SX competitions were included. Injury incidence was
expressed as the absolute injury rate (number of injuries per 100 athletes per season)
and as the relative injury rate (number of injuries per 1000 runs). Results: For SBX the
injury incidence in finals was 12.1/1000 runs compared to 6.1/1000 runs in
qualifications (RR 1.9, 95% CI 1. 1-3.5, p= 0.019). For SBX males the injury incidence
was higher in finals (12.9/1000 runs) compared to qualifications (4.4/1000 runs) (RR
2.9, 95% CI 1.4-6.2, p= 0.0065). This was not the case for SBX females (finals
10.5/1000 runs vs. qualifications 9.3/1000 runs, RR 1.1, 95% CI 0.5-2.8, p= 0.79). For
SX the injury incidence in finals was 12.4/1000 runs compared to 9.2/1000 runs in
qualifications (RR 1.4, 95% CI 0. 8- 2.3, p=0.27). The injury incidence for SX males
was 13.6/1000 runs in finals vs. 8.8/1000 runs in qualifications (RR 1.5, 95% CI 0.8-
3.1, p=0.21). The injury incidence for SX females was 10.8/1000 runs in finals vs.
9.8/1000 runs in qualifications (RR 1.1, 95% CI 0.5-2.6, p= 0.83). The injury incidence
per 100 athletes was 14.2 in SBX and 16.3 in SX. There were no differences in injury
severity between run types in either discipline. Conclusion: The injury incidence was
significantly higher in final runs vs. qualification runs in SBX in total, and for SBX
males when analysed for sex. For SBX females and in SX no significant differences
between the injury incidence in qualification and final runs were found. Keywords:
