Although permitting only incidental contact, women's lacrosse had higher rates of head, face, and eye injuries at both the high school and collegiate levels. Concussion was the most common injury. For men, the primary injury mechanism was player-to-player contact; women's injuries primarily resulted from stick or ball contact. High school injury rates were lower than were college rates, but the nature of injuries, body parts affected, and mechanisms were similar.

Results of this study demonstrate that roller hockey produces a higher rate of both contact and noncontact injuries than ice hockey; this contradicts the findings of the only other published research study on injuries in roller versus ice hockey. This increased incidence of injury may be due in part to the differences in surfaces, and can prove hazardous to even the recreational roller hockey player or in-line skater.
