The quadriceps femoris – known as the quadriceps extensors, quads, or the quadriceps – is a group of four different muscles on the anterior thigh.  Quadriceps femoris is a Latin term that translates to “four-headed muscle of the femur.  The most superficial of the four muscles is the rectus femoris.  Deep to the rectus femoris lies (from the lateral side of the femur to the medial side) the vastus lateralis, vastus intermedius, and vastus medialis.

What Do They Do?

If you check out the previous articles about the calves, hamstrings, and the glutes, you’ll notice that all of these lower body muscles assist with the same movements.  Walking, running, kicking, jumping… all of these large powerful muscle groups, the quadriceps femoris as well as the above mentioned three, are responsible for the completion of those actions!

More specifically, however, what does each individual quadricep muscle do?

Making it Strong

Most exercises targeting the quadriceps don’t require special equipment but adding some weights – so long as your body isn’t shaking or surpassing its limits – can add an extra benefit!  Basically, anything with the word “squat” in it is going to get the quads pumping!

The Best Stretches

You’ve done all your squats now and it’s time to stretch!  Post-workout muscles are warm, and warm muscles are more pliable muscles.  Do the following stretches while the fibers are most flexible!

Keeping it Happy

Deep tissue massage is an effective treatment for tightened hamstrings.  It’s worth noting, though, that the posterior thigh is a hotspot of trigger points. Trigger point therapy can knock out those hyper-irritable cesspools of lactic acid with a dig of an elbow.

As with any bodywork session, you get the ultimate benefit if you go a step further than removing knots from locked-short muscles. When you have hyper-contracted quadriceps, the muscles on the front of your thigh overstretch and weaken.  Take a look at the hamstring article mentioned in a previous section and take a look at exercises and stretches for the quadriceps’ antagonistic muscle group!  While you can always practice the techniques at home, you can also ask your therapist to assist you with them; PNF is used for both strengthening and improving range of motion.

Now You Know!

Do your squats, extend those legs, and hit the leg press! Next time, we’ll talk about a muscle group that sits just above the four quadricep muscles; the hip flexors!
