The Effect of Strength Training on the Hip Adduction Strength Measured With Hand-held Dynamometry

The purpose of this study is to investigate the effect of strength training with elastic bands on hip strength in soccer players, the effect measured with hand-held dynamometry. The primary outcomes are isometric and eccentric hip adduction strength. The hypothesis is that strength training with elastic bands will result in a clinical relevant increase in hip adduction strength.

Inclusion Criteria:

• Sub-elite danish soccer players

Exclusion Criteria:

• Injury in the lower back or legs with a duration of more than 6 weeks within the last year before the study was initiated.
• Systematic strength training of the hip adductors more than once a week within the last 6 months before the study was initiated.
• Groin pain during soccer play with a duration of more than 1 week and witch resulted in loss of soccer training/game within the last 3 months before the study was initiated.
• Groin injuries within the last month before the study was initiated.
