About

This research project will investigate the effects of two 6-week adductor (hip muscle) exercise programmes on adductor muscle function and performance.

Measures of adductor muscle strength and performance (jump height, hopping and sprint) and self reported hip and groin function using a questionnaire will be recorded pre and post a 6-week period. A group of footballers will be recruited and randomly allocated to an intervention or control group. Two different intervention groups will complete two different, six-week adductor exercise programmes in addition to their regular training programme. The exercise programmes will last 15 minutes (approximately) per session, with 3 sessions per week. The control group will continue their regular training programme.

Full description

Participants will be recruited from the local university sports clubs. Club chairpersons will be asked to send an email to club players. Players interested in participating in the study will be asked to attend a meeting where the study will be explained to them. Those who were interested will then be assessed for inclusion and exclusion criteria.

Group allocation:

A four block randomization method will be used to allocate participants to the Copenhagen adductor exercise protocol or the adduction and abduction partner exercise protocol.

Interventions:

Copenhagen adductor exercise protocol or the adduction and abduction partner exercise.

Testing procedure:

The isometric strength of the participants' hip adductors and abductors will be recorded before and after the exercise intervention.

A 10 point visual analogue scale will be used to record the level of muscle soreness experienced after each training session.

Enrollment: 60 estimated patients

Sex: Male

Ages: 18 to 35 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• free from hip and groin injury in the 6 months prior to the study • currently competing in team sports at least three occasions per week

Exclusion criteria

• history of a hip or groin injury in the 3 months prior to the study
• a history of involvement in an adductor strengthening, injury prevention programme in the 3 months prior to the study.

60 participants in 2 patient groups

Copenhagen adductor exercise

Active Comparator group

Description:

The modified Copenhagen adductor exercise consists of 6 levels through which the participant will progress when able to complete one level adequately (able to complete the exercise in the given timeframe with adequate control). The first 5 levels are isometric contractions progressing in difficulty with the 6th level including concentric and eccentric components. 1. Participants perform a supported isometric adduction hold off a 30cm support in a short-lever side-lying position. The participants then raise their pelvis from the floor, keeping their lower knee on the ground for support and hold for 20 seconds, repeating it twelve times on each side. 2. Participants progressed level 1 by lifting their supporting leg, bringing their knees together and holding position for 20 seconds, repeating it twelve times on each side.

Other: Copenhagen adductor exercise

adduction and abduction partner exercise

Experimental group

Description:

Participants are in a sitting position with their knees extended and hips abducted, supporting themselves with their hands behind their trunks, facing each other. For the adduction exercise, the participant will place his feet and lower leg on the outside of his partner's lower legs and feet. He will then adduct his hips, bringing his feet slowly together while his partner slowly resists this movement. For the abduction exercise, the participant will place his feet and lower legs on the inside of his partner's feet and lower legs. The participant will slowly abduct the hips while the partner resists this movement. Both exercises are performed over 6 seconds (a three second concentric and three second eccentric contraction) with as maximal effort.
