Scientific title

Effect of a preventive exercise programme on the prevalence and intrinsic risk factors of anterior knee pain in volleyball players

Acronym

Study hypothesis

Has a preventive exercise programme, designed as a result of systematic literature reviews, an effect on the prevalence and intrinsic risk factors of anterior knee pain in volleyball players?

Condition

Anterior knee pain disorders

Intervention

Control group:
Normal training routine

Intervention group:
Normal training routine and exercise programme based on systematic literature reviews. The programme lasts four months and involves the following exercises:
1. Closed kinetic chain exercise for isometric strength
2. Open kinetic chain exercise for isometric strength
3. Eccentric exercise and plyometrics with emphasis on technique

The intervention lasts four months, each month another accent:
1. 1st month: emphasis on closed kinetic chain exercise for isometric strength
2. 2nd month: emphasis on closed kinetic chain exercise for isometric strength
3. 3rd month: also eccentric exercise were included
4. 4th month: also plyometrics with attention of landing technique is added

It is a progressive programme and includes strength exercises for vastus medialis (quadriceps), hamstrings, gluteus medius and adductors. It also includes stretching exercises of those muscle groups.
