A muscle that moves a body part (e.g. an arm or leg) towards the midline of the body. A strain of the thigh adductors is a relatively common injury of horse riders, fast bowlers, and footballers who make lunge tackles. A simple exercise called the adductor stretch reduces the risk of injury (figure 2). It is also useful for pregnant women and others whose thighs tend to rotate inwards causing backache and flat feet.

1. Any muscle that causes adduction.
2. One of the three anterior thigh muscles (adductor brevis, adductor longus, and adductor magnus), which move the thigh towards the midline of the body.
