As the name suggests, the Adductors move each leg in toward the midline (adding to the middle as opposed to Abductors).
There are five adductors. They all attach on the inside of the femur (leg bone), and on the pubic bone (see image). In order of their attachments on the femur in proximity to the groin:
Injury or Inflammation in the adductor muscles or tendons can occur and is common in athletes, and is due to overuse and repetitive stress. Most often, it shows up as pain in the groin area.
Sprinting, football, soccer, hurdling and horse riding can all cause overuse in these muscles. Unresolved injuries such as groin strain can also lead to tendinitis.
Signs and symptoms: Pain in the groin area. Pain when bringing the legs together against resistance. Pain when running, especially sprinting.
Complications (if left unattended): If left unattended, tendinitis of the adductor muscles can lead to imbalance and injury to the other muscles of the hip joint. It can also result in a tear of one or more of the adductor muscles.
Immediate Treatment: Ice and rest from activities that cause pain. Heat and massage to promote blood flow and healing.
Rehabilitation and Prevention: Rehabilitation for tendinitis of the adductors starts with gradual reintroduction into activity with stretching and strengthening exercises for the affected muscles. Always make sure to warm up properly and get the muscles ready for activity. Strengthening the adductors and stretching the opposing abductors will help prevent this injury from recurring.
