The Copenhagen Adductor Exercise Trial

The purpose of this study is to investigate the efficacy of a 6-week intervention, using the Copenhagen adductor exercise, on adductor muscle strength in sub-elite male footballers. Secondly, it will also examine the effect of a 3-week detraining period, after stopping the Copenhagen adductor exercise, on adductor muscle strength. The primary outcome measure is eccentric hip adduction strength measured using a handheld dynamometer. Additionally, peak isometric adductor squeeze strength will also be measured using a handheld dynamometer. The hypothesis is that strength training of the adductor muscles elicited by the Copenhagen adductor exercise will result in enhanced eccentric hip adduction strength.
