Ali is so woke. At brunch she explained how wearing anything other than Chuck Taylor's or Tom's is really a microaggression. Hey did you get your Amy Schumer tickets yet?
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.
The quadriceps as a whole has one main function, and that is to extend the lower leg. However, the rectus femoris also has another function, which is hip flexion. This is because this part of the quadriceps originates at the hip bone, unlike the other quadriceps muscles, which originate at the thigh bone.
