Professional roller hockey injuries.

OBJECTIVE

To study the incidence and types of injuries sustained by professional roller hockey players in practices and games, and to compare these statistics with those from ice hockey.

DESIGN

This injury survey used a strict definition of injury, standardized reporting strategies, and diagnosis by a team physician as standards by which to analyze the characteristics of roller hockey injuries.

SETTING

The injuries were recorded after the players had been examined by a team physician at the game or practice site or in the physician's office.

PARTICIPANTS

During three seasons for one roller hockey team and one season for another team, an average of 22 players per team participated in the study. Due to personnel changes, the team rosters were modified between seasons. Each player injury was included in the study. An injury was defined as any physical impairment caused during a practice or game that eliminated the player from that practice or game or the next day's practice session or contest, or any physical ailment that necessitated a physical examination by the team physicians.

MAIN OUTCOME MEASURE

Injury data were categorized and injury rates were calculated.

RESULTS

122 injuries were recorded during four professional roller hockey seasons, resulting in an overall participation injury rate of 14.4 per 1,000 player hours. The game injury rate was 304.9 per 1,000 player hours. The players were 105.1 times more likely to be injured during a game than during practice. Preseason practices produced 4.5 times more injuries than regular season practices. In comparison, sample data from the only other published study of roller hockey injuries and from several studies of ice hockey have indicated game injury rates of 139.0 (roller hockey), 119.0, 96.1, 78.4, 78.8, and 66.0 per 1,000 player hours, respectively.

CONCLUSION

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.
