More experience with body checking was not associated with a decrease in the number of concussions or injuries in 15- to 7-year-old ice hockey players.
Although body checking in ice hockey can lead to an increased risk of injury and health care costs, arguments remain that increasing a hockey player’s experience with body checking could protect him from injury.
Eliason and colleagues completed a prospective cohort study to determine the association between body checking experience and rates of concussions and injuries in ice hockey players between 15 and 17 years old.
The researchers invited players from ice hockey leagues in three regions in Alberta, Canada, making body checks possible. All participants completed a baseline questionnaire before the season, which the authors used to estimate the number of years of body checking experience. Designated team members (e.g., manager) recorded each match as an exposure, an injury resulting in more than 7 days lost to hockey, and a concussion as defined in the Consensus Statement on Concussion in Sport.
A total of 186 teams (941 players with 1,168 player seasons) participated. Players with three or more years of bodychecking experience tended to sustain new injuries and concussions more than 2.5 times as often as players with two or fewer years of experience.
Interestingly, having more experience was not associated with fewer injuries. These findings support the theory that more experience with body checking is not protective. Therefore, these findings support rule changes regarding the removal of body checks in youth ice hockey. It will be useful to see if these findings can be replicated in other age groups and populations. In the meantime, doctors, parents and players can use this data to advocate for rule changes to reduce body checks.
Clinicians and stakeholders should advocate for fewer body checks to reduce injuries.
What experiences have you had with rules that limit contact in sports? What implementation barriers have you encountered?
