RT Journal Article T1 Effects of Copenhagen adduction exercise on the architectural characteristics of adductors in U-17 male soccer players: a randomized controlled trial A1 Alonso Calvete, Alejandra A1 Lorenzo Martínez, Miguel A1 Padrón Cabo, Alexis A1 Rey Eiras, Ezequiel K1 2411.06 Fisiología del Ejercicio K1 2411.10 Fisiología del Músculo K1 3210 Medicina Preventiva AB Groin injuries are one of the most prevalent in male soccer players, especially due to the hip adductor muscles’ weakness which is considered as a risk factor in these injuries. The Copenhagen adduction (CA) exercise has been demonstrated to increase the strength of adductor muscles, but its effects on the architectural characteristics of adductor muscles have not been studied yet. This study aimed to analyze the effects of the CA exercise on the muscle thickness of the adductors. Twelve male U-17 soccer players were randomized into two groups: the control group with no intervention and the experimental group with an intervention based on an eight-week training with CA exercise. The muscle thickness of adductors was measured before and after the intervention using ultrasound imaging. A significant increase in muscle thickness was found in both control (p = 0.002) and experimental group (p < 0.001), but the experimental group did not show additional effects in comparison with the control group. In conclusion, an 8-week CA exercise intervention does not increase the muscle thickness of adductors in U-17 soccer players more than their regular training.
