Groin strains are among the most common injuries seen in ice hockey. The purpose of this prospective study was to determine if hip muscle strength and flexibility play a role in the incidence of groin and hip flexor strains in an National Hockey League (NHL) professional ice hockey team.

Preseason measurements of hip strength and flexibility were made on 81 players on two consecutive years. Hip flexion, abduction and adduction strength were measured with an instrumented manual muscle-testing device. Hip adductor and hip flexor flexibility were measured goniometrically.

Of the 81 players who had preseason testing 34 were cut, traded or sent to the minor league prior to the beginning of the season. Injury and individual exposure data was recorded on the remaining 47 players.

There were 11 groin strains in eight players (one player had bilateral strains and two players had a recurrence in the second season). There were only four hip flexor strains. Preseason hip adduction strength was 18% lower in the players who subsequently sustained a groin strain compared to uninjured players.

Additionally, adduction strength was 95% of abduction strength in the uninjured players but only 78% of abduction strength in the injured players. Preseason hip adductor flexibility was not different between the players who subsequently sustained groin strains and the uninjured players.

These results indicate that preseason hip strength testing of professional ice hockey players can identify players at risk of developing groin strains. The best predictor of injury was the hip adduction to abduction strength ratio. A player was 17 times more likely to sustain a groin strain if their adductor strength is less than 80% their abductor strength.
