Injuries in Youth Ice Hockey: A Pilot Surveillance Strategy

Objective

To determine the incidence and type of injuries in youth hockey players during practice and games as well as to test the applicability of the current methods to a national surveillance study of youth hockey injuries.

Design

During the 1993 to 1994 season, we undertook a prospective observational analysis of youth hockey players on four competitive teams at three levels of participation: Squirt, Peewee, and Bantam.

Material and Methods

In a study group of 66 youth hockey players, types and anatomic sites of injury, mechanisms of injury, player position affected, and occurrence of injuries during practice or games were determined and analyzed statistically. An injury was strictly defined, standardized reporting strategies were used, and a single physician examined all injured athletes and made the diagnoses.

Results

A total of 14 injuries occurred during the season. The on-ice injury rate (per 1,000 player- hours) was 1.0 at the Squirt level (ages 9 and 10 years), 1.8 at the Peewee level (ages 11 and 12 years), and 4.3 at the Bantam level (ages 13 and 14 years). No game injuries and only one mild practice injury occurred in Squirt players (N = 16), and only two mild injuries occurred during practice sessions for Peewees (N = 17). No differences were noted between practice injury rates at the various levels; all recorded game injuries occurred only in Bantam players (N = 33). The most common types of injuries were contusions, fractures, strains, and sprains. The arm and shoulder were most frequently injured.

Conclusion

Further research is necessary to determine whether injuries in youth ice hockey can be reduced by changes in playing rules, enforcement of existing rules, improvements in protective equipment, alteration in coaching techniques, and institution of educational programs.

MATERIAL AND METHODS

The study was approved by the Mayo Clinic Institutional Review Board before it was introduced at team meetings to parents, players, and coaches of four competitive traveling teams at the Bantam, Peewee, and Squirt levels of participation. These teams represented their youth hockey association in league and nonleague play throughout Minnesota. All players and parents voluntarily completed the informed consent forms, and players participated in a preseason screening physical examination. This

RESULTS

The biographic and physical examination data were analyzed for differences between the age-groups (Table 1). Height, weight, sexual maturity rating, flexibility, heart rate, and number of years in hockey were compared by using the Student t test. This compilation provided information on players at various age levels. Bantam and Peewee players did not differ in resting heart rate; however, Bantam players had significantly higher values for all other physical categories than did players at the

DISCUSSION

The potential for injury in ice hockey has been attributed to physical, behavioral, biomechanical, and equipment factors.6 High-impact collisions with the boards, ice, and opposing players are common. Sim and Chao7 measured sliding speeds of 24 km/h (15 mph) with use of high-speed cinematography. Noncontact forces during skating were estimated at 1.5 to 2.5 times the body weight; thus, rapid changes in acceleration and deceleration can result in soft tissue trauma. The hockey puck maximal

ACKNOWLEDGMENT

We thank coaches Kirk Gill, Will Fish, Mike Lauritzen, and Tom Taylor for their diligence and interest in this project. We are indebted to the players and their parents, who willingly participated and conscientiously reported any injuries that occurred.
