The groin muscles are sometimes also call the 'adductor's. This describes the movement that they all perform. There are five adductors in total.
The groin muscles include:
The three adductor muscles are typically thought of as the groin muscles, although the pectineus and gracilis also assist them in adducting in the hip.
Adduction is the movement of bringing the leg in, towards the centre of the body. This movement is performed when kicking. The adductor muscles also help to flex the hip (lifting the leg up).
Gracilis also help to bend the knee and internally rotate the hip. Adductor Magnus can also help to extend the hip.
