Effects of a groin pain prevention program for male high school soccer players: a cluster-randomised controlled trial

Groin pain (GP) is one of the most common pain conditions reported by soccer players, but few reports have examined the effects of preventive exercise interventions on high school soccer players. In addition, there is a Copenhagen adduction exercise (CAE) as a preventive exercise for GP, but there is no report that examined the combined intervention effect with the Nordic hamstrings exercise(NHE). The purpose of this study was to investigate the preventive exercise effects in high school soccer players.
