To determine if pre-season adductor squeeze test and HAGOS function, sport and recreation subscale scores can identify Gaelic football players at risk of developing groin injury.Prospective study.Senior inter-county Gaelic football team.Fifty-five male elite Gaelic football players (age = 24.0 ± 2.8 years, body mass = 84.48 ± 7.67 kg, height = 1.85 ± 0.06 m, BMI = 24.70 ± 1.77 kg/m2) from a single senior inter-county Gaelic football team.Occurrence of groin injury during the season.Ten time-loss groin injuries were registered representing 13% of all injuries. The odds ratio for sustaining a groin injury if pre-season adductor squeeze test score was below 225 mmHg, was 7.78. The odds ratio for sustaining a groin injury if pre-season HAGOS function, sport and recreation subscale score was < 87.5 was 8.94. Furthermore, for each additional point on the numerical rating scale pain rating during performance of the adductor squeeze test, the odds of groin injury increased by 2.16.This study provides preliminary evidence that pre-season adductor squeeze test and HAGOS function, sport and recreation subscale scores can be used to identify Gaelic football players at risk of developing groin injury.
