Why do joints make cracking sounds when doing push-ups?

When our body sits for a long time or the joints are in a static state, if we stand up suddenly or turn the joints greatly, the joints will make a "pop" sound. Especially for those who like fitness, joint cracking often occurs when doing push-ups at home or outdoors. Many people feel confused about this. Why do joints make noises when doing push-ups? The editor below will explain it to you.

1) Gas escape: Scientists believe that there is a liquid called synovial fluid between our joints, which is used to lubricate the joints. This synovial fluid contains gases such as oxygen, nitrogen and carbon dioxide. These gases form bubbles in the synovial fluid. When we stretch our joints, the gases in the synovial fluid escape rapidly, causing hiccups as the bubbles burst.

2) Joint displacement: When we move a joint, tendons and ligaments are displaced. You may sometimes hear a hiccup as the tendons and ligaments return to their original position. This situation is more common in the knee and ankle joints.

3) Rough joint contact surface caused by arthritis: Arthritis can destroy the cartilage tissue between joints, causing the joint contact surface to no longer be smooth. In this case, the friction between the joints will produce noise. Is the sound produced by moving joints harmful to the body? Not necessarily.

If you experience burping sounds and pain when you move your joints, see your doctor.

Some people like to move their knuckles to produce sounds. Some research reports point out that this habit can damage the soft tissue between the knuckles and weaken the grip of our fingers.

Beginners often have this phenomenon, and it should be said that most of it is normal. Some parts and angles of human joints are seldom moved on a daily basis. Just like a new car, it needs a running-in period before it can move smoothly. The shoulder joints in particular are less active at ordinary times, but in Tai Chi, the joints often make circular motions and lifting and lowering movements, which will make the "dead" joints more active.

"The joints become active, so it is inevitable that they make noises at the beginning. But be careful, beginners must pay attention to the relaxation of the joints, let it go naturally, don't force yourself to do strenuous movements, the joints can be turned as far as they can, don't show off, and don't be afraid of hardship or pain, pay attention to protecting the joints from damage. Once a joint is damaged, it is often irreversible and a lifelong problem. As long as you persist, the joints will naturally open over time. Don't be impatient. After practicing for one to two months, if you practice every day and it still makes noises, there may be a problem. You need to temporarily stop practicing and go to the hospital for a check-up.

The above content is the editor’s introduction to why joints make noises when doing push-ups. I believe you all have some understanding after reading it. Different noises in the joints during exercise means that this method is healthy. You may mistakenly think that it is the joints that are being exercised, but in fact it is the friction of the joints that is compressing the air contained in the joint joints. If you hear cracking and pain in your joints when twisting them during exercise, it is recommended that you go to the hospital for a check-up to achieve the purpose of prevention.
