^*There were no significant differences in the severity of groin pain between the three groups. Due to the low number of injuries, minor injuries were compared to the category that combined moderate and severe injuries. Fisher’s exact test, p = 0.21.

^†Group A= Copenhagen adduction exercise alone. Group B= combined intervention of Copenhagen adduction exercise and Nordic hamstrings exercise. Group C= continues as usual.
