Why does the VMO atrophy?

Why does the VMO atrophy?

Finally, the exact cause of this morphological change is also debatable. The most common explanation is that the quadriceps atrophy is caused by reflex inhibition leading to loss of muscle contractility and thus muscle size over time7. This phenomenon is commonly referred to as ‘autogenic muscle inhibition’ or AMI8.

How do I strengthen my vastus medialis obliquus?

How To Do Vastus Medialis Exercises

  1. VMO Activation. Sit upright in a chair, with your knees bent, ball between your knees and your feet flat on the floor.
  2. Ball Clench Extensions.
  3. Twisted Leg Raise.
  4. Ball Bridges.
  5. Ball Wall Squats.
  6. Vastus Medialis Stretch.

What is vastus medialis obliquus?

The portion of the muscle that is just above the knee is sometimes referred to as the vastus medialis obliquus, or VMO. This muscle is used to extend the leg at the knee and to stabilize the patella, which is also known as the kneecap.

What happens if you have a weak vastus medialis?

Your vastus medialis helps to stabilize your kneecap and keep it in line when you bend your knee. If you have knee pain or a knee injury, it may be due to weakness of your vastus medialis or other quadriceps muscles.

How do you treat muscle atrophy?

Disuse (physiologic) atrophy can be treated with regular exercise and better nutrition. Your healthcare provider may recommend physical therapy or an exercise plan. Even if you can’t actively move certain joints in your body, you can do still exercises wearing a splint or brace.

What is a weak VMO?

Sometimes a weak VMO can develop through bad training habits, but often the VMO becomes weak because of an underlying problem in the knee, of which there can be many. It is usually the first muscle to show signs of an underling problem, and this should not be ignored.

Does cycling strengthen VMO?

These stabilize and support the VMO, but you need to strengthen it because cycling predominantly builds the other 3 quad muscles and only marginally strengthens the VMO. This leads to quad muscle imbalance and the vastus lateralis (outer quad) pulling the patella to the outside of the leg.

Does running strengthen VMO?

The VMO is hard to strengthen and running does not stimulate the VMO to help stability.

Can VMO cause knee pain?

The vastus medialis (vastus medialis oblique, or VMO) is one of the four quadriceps muscles in the front of your upper thigh. The teardrop-shaped muscle helps move the knee joint and stabilizes the kneecap. Injury to the vastus medialis can cause knee pain and difficulty walking, running, or managing stairs.

How do you heal VMO?


  1. apply heat to the VMO muscle 10 minutes each day to increase blood flow and reduce tension.
  2. if you’re a runner or hiker, avoid the hills (in the short-term)
  3. ensure your shoes are not overly worn.

Can muscles recover from atrophy?

Disuse (physiologic) atrophy is usually reversible, but it won’t happen overnight. You can recover from muscle atrophy by exercising regularly and eating a healthy diet. You may start seeing improvement after a few months, but it may take much longer for you to fully recover your strength.

Is muscle atrophy permanent?

Causes of muscle atrophy. Unused muscles can waste away if you’re not active. But even after it begins, this type of atrophy can often be reversed with exercise and improved nutrition. Muscle atrophy can also happen if you’re bedridden or unable to move certain body parts due to a medical condition.
