What Are the Symptoms and Common Causes of a Pulled Quad Muscle?

All but the most minor quad pulls are painful. Some typical symptoms of a pulled quad muscle include:

sudden, sharp pain at the front of the upper leg during exercise – most usually felt during sprinting or bursts of speed and potentially accompanied by a “popping” feeling. The quads are responsible for straightening the leg, so such motions can be quite uncomfortable.
a spasm or stiffness in the upper leg, especially felt when stretching.
swelling and tenderness
bruising in the upper leg (which indicates blood vessels have been ruptured)
overall weakness in the quadriceps
gap or irregularity in the quad muscle, which is usually the sign of some form of muscle fiber tear

There are many causes for quad muscle pulls, but here are a few of the most common.

lack of flexibility in the quadriceps – even a mild force can pull a tight muscle
poor quadriceps strength
strength or flexibility imbalance between the hamstring and the quadriceps. These muscle groups work opposite one another, so having a complimentary amount of strength and suppleness in both groups is important
being overtired or not warming up prior to stressful activity
overstretching the quadriceps
sudden stress upon quadriceps
impact to the quadriceps by an outside force

Additionally, if you are tired or your muscles are cold, this increases your chances for a muscle pull.
