Eccentric strengthening effect of hip-adductor training with elastic bands in soccer players: a randomised controlled trial
Hip and groin injuries make up approx 20% of all soccer injuries. Adductor-related groin injuries constitute 63% of all injuries to this region and decreased muscle strength of hip adductors has been shown to be a risk factor for groin injuries.
The authors of this study wanted to evaluate the effects of 8 week hip-adductor strengthening program. 34 healthy sub-elite soccer players were randomized to training or control groups and during midseason break the training group performed 8 weeks of supervised (by physiotherapist), progressive hip adduction training using elastic bands. The primary outcomes were maximal eccentric (EHAD) and maximal isometric (IHAD) hip-adduction strength, measured only of the dominant leg, with a handheld dynamometer.
There was a 30% increase in EHAD and 14% increase in IHAD in the training group. This study showed that this strengthening program can increase the maximal eccentric hip-adduction strength substantially and is simple and can be performed at the soccer field, thus having potential implications as a simple approach to groin injury prevention in soccer. > From: Jensen et al., Br J Sports Med 48 (2014) 332-338.
