About

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.

Copenhagen adductor exercise

Experimental group

Description:

20 players allocated to the Copenhagen adductor exercise group complete a progressive strengthening programme comprising of the Copenhagen adductor exercise over a period of 6 weeks. They will complete two exercise sessions a week consisting of one set of the Copenhagen adductor exercise. The exercise will be performed on each side. The training load will increase from 5 repetitions in week 1, to 15 repetitions in week 6. The exercise programme is performed at the end of the warm-up of a regular football training session.

Treatment:

Other: Copenhagen adductor exercise

Control

No Intervention group

Description:

19 players allocated to the control group will be asked not to perform the Copenhagen adductor exercise or any other specific strength training for the adductor muscles and to continue to play football as usual.
