Abstract

Background: Lacrosse and ice hockey are quickly growing in popularity, while football remains the most popular sport among high school student-athletes. Injuries remain a concern, given the physical nature of these contact sports.

Purpose: To describe the rates and patterns of injuries sustained as a result of intentional player contact in United States high school boys' football, ice hockey, and lacrosse.

Study design: Descriptive epidemiology study.

Methods: We conducted a secondary analysis of High School RIO (Reporting Information Online) data, including exposure and injury data collected from a large sample of high schools in the United States from 2005-2006 through 2015-2016. Data were analyzed to calculate rates, assess patterns, and evaluate potential risk factors for player-to-player contact injuries.

Results: A total of 34,532 injuries in boys' football, ice hockey, and lacrosse occurred during 9,078,902 athlete-exposures (AEs), for a rate of 3.80 injuries per 1000 AEs in the 3 contact sports of interest. The risk of injuries was found to be greater in competition compared with practice for all 3 sports, with the largest difference in ice hockey (rate ratio, 8.28) and the smallest difference in lacrosse (rate ratio, 3.72). In all 3 contact sports, the most commonly injured body site in competition and practice caused by both tackling/checking and being tackled/checked was the head/face. However, a significantly greater proportion of concussions sustained in football were the result of tackling compared with being tackled (28.2% vs 24.1%, respectively). In addition, a significantly greater proportion of concussions were sustained in competition compared with practice for all 3 sports.

Conclusion: This study is the first to collectively compare injury rates and injury patterns sustained from intentional player-to-player contact in boys' high school football, ice hockey, and lacrosse. Notably, there was a relatively high risk of injuries and concussions during football practices.

Football, ice hockey, and lacrosse time loss after an injury by type of player-to-player contact. Intentional player contact was defined as tackling or being tackled in football and checking or being checked in lacrosse and ice hockey. <1 week = includes athletes returning to activity in less than 1 day. Other = athlete choosing not to continue, athlete being released from the team, and other.
