The groin muscle
Adductor longus · musculus adductor longus
The inner-thigh muscle most often pulled in a "groin strain".
What it does
The adductor longus runs from the front of the pubic bone to the middle of the femur. It pulls the thigh in towards the other leg and helps bend the hip. Its tendon forms a firm cord you can feel at the top of the inner thigh.
Surprising fact
It is the most commonly injured muscle in a groin strain, especially in football and ice hockey, where players kick and change direction sharply.
Why it matters
Warming up and strengthening the inner-thigh muscles cuts the risk of groin strains, which can be slow to heal.
