Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

• isometric hip adductor and abductor strength

  The maximum isometric hip abductor and adductor strength is assessed with the participant being tested was in supine position, with the test-leg placed at the end of the examination table, and the opposite leg slightly flexed. The dynamometer is placed 5 cm proximal to the proximal edge of the lateral mal¬leolus or 5 cm proximal to the proximal edge of the medial malleolus for hip abduction and adduction, respectively. The dynamometer is externally fix¬ated by the tester's hand/arm placed between the wall and the dynamometer. Participants are initially given two warm up trials of each test of the hip abductors and adductors at 50% and 100% of maximal voluntary isometric force (MVC), followed by three valid MVC trials at the rate of one trial every 60 s

• Hop test function

  Single leg hop - the participant will hop as far forwards as possible. Triple hop for distance. Participants will be asked to hop forward three times in a row as far as possible. Crossover hop test. A 3 metre strip of tape will be place on the ground in front of the participants. Participants will be asked to stand on one foot with the tape to the outside of their stance foot. They will then be asked to hop forward three times in a row as far as possible while alternately crossing over the tape and then landing on the same foot, and holding this position for two seconds. Side hop test. Participants will be asked to jump from side to side as many times as possible in 30 seconds without touching the tape. The number of successful jumps will be recorded.

Copenhagen adductor exercise

ACTIVE COMPARATOR

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.

adduction and abduction partner exercise

EXPERIMENTAL

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.
