SPORTS ANATOMY LESSON #4
HIP ADDUCTOR MUSCLES
The adductor muscles are a group of four muscles located in the internal femoral region on both sides of the body. Their names are: 1) Adductor Longus, 2) Adductor Brevis, 3) Adductor Magnus, and 4) Gracilis. These muscles are shown in Figure 1 below
Figure 1. The Hip Adductor Muscles.
INNERVATION (NERVE SUPPLY)
The nerve supply to the all of the adductor muscles is from the Obturator nerve. The Adductor Magnus receives additional nerve supply from the Great Sciatic Nerve. See Figure 2:
Figure 2. Great Sciatic Nerve and Obturator Nerve.

Function
The adductors main function is to adduct or bring your legs towards the midline of the body. This occurs during any athletic movement requiring you to move from side to side such as playing the infield in baseball, defense in basketball and football, and ice skating. They are also used in activities such as horseback riding where inward pressure by your thighs is required to maintain a firm and stable riding posture. See Figure 3:

They also are responsible for adducting or crossing your legs across the midline of the body. This occurs in athletic movements such as kicking a soccer ball or placekicking in football. This is illustrated in Figure 4 below:
