what are quadriceps muscles
Quadriceps strain explained. The quadriceps muscles are the muscles on the front of the thigh. They consist of the vastus lateralis, vastus medialis, vastus intermedius and the rectus femoris. A strain is a tear in the muscle. These can range in severity, from a very small tear to a complete rupture. Tears to the quadriceps muscles usually occur following an activity such as sprinting, jumping or kicking, especially if a thorough warm-up hasn't been undertaken.
