To compare sex differences regarding the incidence of concussions among collegiate athletes during the 1997-1998, 1998-1999, and 1999-2000 seasons. DESIGN AND SETTING: A cohort study of collegiate athletes using the National Collegiate Athletic Association (NCAA) Injury Surveillance System; certified athletic trainers recorded data during the 1997-2000 academic years. SUBJECTS: Collegiate athletes participating in men's and women's soccer, lacrosse, basketball, softball, baseball, and gymnastics. MEASUREMENTS: Certified athletic trainers from participating NCAA institutions recorded weekly injury and athlete-exposure data from the first day of preseason practice to the final postseason game. Injury rates and incidence density ratios were computed. Incidence density ratio is an estimate of the relative risk based on injury rates per 1000 athlete-exposures. ⋯ Female athletes sustained a higher percentage of concussions during games than male athletes. Of all the sports, women's soccer and men's lacrosse were found to have the highest injury rate of concussions. Incidence density ratio was greatest for male and female soccer players.

To compare the log-roll (LR) maneuver and the lift-and-slide (LS) technique and to investigate the effect of training on the performance of these transfer techniques. DESIGN AND SETTING: A repeated-measures design involving certified athletic trainers and athletic training students from a National Collegiate Athletic Association Division I college. SUBJECTS: Certified athletic trainers and athletic training students were required to transfer healthy individuals onto a spine board. Testing was performed on 2 men of average size, whereas training sessions were performed on both men and women of different heights and weights. ⋯ The LS technique was more effective in restricting motion of the head. To truly establish the safety of spine-board transfer techniques, researchers need to assess how individual segments move within the structurally unstable cervical spine.
