title: Orienteering competition injuries: injuries incurred in the Finnish Jukola and Venla relay competitions.
abstract: OBJECTIVE
  The aim of this study was to find out the amount, type, and localisation of acute orienteering injuries in the 1995 Finnish Jukola (men's) and Venla (women's) relay competitions with 9724 participants.
  
  
  METHODS
  Patient data were collected on a preplanned form at the first aid station.
  
  
  RESULTS
  There were 244 acute competition injuries. The overall injury incidence was 2.5% (95% confidence interval (CI) 2.2 to 2.8), 2.3% in the men's relay and 3.2% in the women's relay, and the difference between incidences among men and women was statistically significant (odds ratio (OR) 1.4; 95% CI 1.1 to 1.9). The injury rates were also calculated per 1000 competition hours and per 1000 km and were 15.4 and 2.6 respectively. Most of the injuries could be treated at the first aid station. Female orienteers had more blisters (OR 4.4; 95% CI 2.5 to 7.9) and fewer wounds (OR 0.5; 95% CI 0.2 to 1.0) than male orienteers. Injuries occurred mostly in the lower extremities (70%), and ankle sprains accounted for 25% of all injuries. Injuries were more common during the first leg of both relays.
  
  
  CONCLUSIONS
  This study shows the heavy workload in a first aid station of a big orienteering relay competition. It indicates a difference in injuries between the sexes and in the different stages of the relay, which should be further investigated in order to prevent orienteering competition injuries.
