What if crunching knees

Knees - this is one of the most traumatic zones in sports. Orthopedic surgeon Michael Stewart, who works in the Mayo Clinic, told when to and when not to worry about the strange crackle in her knees. It turns out, it is not so simple.

Recently, the site The New York Times there was a small an interview with Dr. Michael Stewart, Who spoke about the causes of a crunch in her lap. It turns out, snapping and crackling sound in the joints called "crepitus". In most cases, it is the gas bubbles that burst at movement joints. In rare cases crepitus arises from the fact that the cartilage loses its elasticity, causing the tissue begin to rub against each other, causing the sound.

I was wildly annoying crunching knees. Crunching sounded not always, but only when I have stretched their maximum, for example, sitting in a pose of a baby. It's like this:

And after a while I felt that after this position and crunch the knees feet becomes easier. Then I realized that the crunch in your lap - it's not always a bad thing, and decided to look into the matter.

According to Stewart, it is necessary to answer only one question:

Do crunch is accompanied by pain in the knee joints?

If you feel a sharp pain, tingling, or heaviness in your lap during exercise, this may be due to arthritis. Then you need to be sure to see a doctor.

Also, the crunch can be caused by the fact that you give the knee joints too great a burden. For example, squatting too deep. Although professionals are advised to squat so, you need to know when to stop.

With deep squat the hip joint is lower than the knee, loading it beyond measure. Michael Stewart also said that at a deep squat on the knee joint has to load equal to eight times the body weight. Add to that the weight of the barbell on your shoulders, and you will understand why eventually knees begin to crackle.

Here are a few key tips:

1. If you do not want to overload the knees, squat up to an angle of 90 degrees.
2. If the crunch in the joints accompanied by pain, it is necessary to visit a doctor.
3. Deep squat can adversely affect the knees.
4. Cracking in knees without pain is called "crepitus" and does not cause them any harm.
