About this study
Official title: Hip Adductor Muscle Strength Changes With the Copenhagen Adductor Exercise in Male Football (Soccer) Players.
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Copenhagen adductor exerciseOther
Also called Adductor bridge exercise
The active player is supported on one forearm on the floor and the upper arm is resting along their side. The supporting partner places their hands at the ankle and the knee of the upper leg. The active partner raises their body from the floor and adducts both legs in a three second movement until the body reaches a straight line. The body is then lowered to the ground in a three second movement, the foot of the lower leg touches the ground before performing another repetition.
| Study group | Role | What they receive |
|---|---|---|
| Copenhagen adductor exercise | Experimental | 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. Receives: Other: Copenhagen adductor exercise |
| Control | No intervention | 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. |

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Dec 2018.
