Joints make noises when exercising

Many friends will feel noises in their joints when exercising. This phenomenon is actually normal. There are two main reasons for such noises. One is the noise in the joints during exercise, and the other is the noise caused by normal joint activities. Both are normal phenomena and have no effect on the body. However, if you feel pain in the joints, you should do relevant examinations in time.

During fitness exercises, some people often hear "crunching" or "clicking" sounds in some joints when doing movements such as knee flexion and extension, shoulder swing or fist clenching. This is a common phenomenon.

Generally speaking, there are two possibilities for joint cracking during exercise. One is that the joint moves normally and produces sound, without any pain. The other type of sound is caused by lesions in the joint itself or its surrounding tissues, most of which are accompanied by pain. During exercise, due to heavy load or strong muscle contraction, the joint surfaces collide or squeeze and rub against each other, making a low-pitched sound; when the joint is pulled by external force, the bones that make up the joint are pulled apart, the joint capsule expands, the negative pressure in the joint cavity increases, and the synovial fluid vibrates sharply, making a higher-pitched sound (such as the sound made when stretching the knuckles). The above two types of joint noises are produced by normal joint activities. They are physiological and harmless to the body. They are more common in people who are new to sports and have weak muscles around the joints. As your fitness level improves, your muscles become stronger, your ligaments become more rigid, and your movements become more coordinated, the noise will lessen.

Some people have hyperplasia and thickening of certain tissues inside and outside the joints, and some people have congenital joint deformities. When the joints move, friction increases, and sometimes a high-pitched, jumping sound is emitted, which is called snapping. If this is the case, you should do special warm-up exercises for the noisy joints before exercise, and do local massage and hot compresses after exercise to improve local blood circulation and prevent excessive growth of tissues inside and outside the joints. Some people have injured their joints, which disrupt the normal relationships of their joints. When exercising, there is not only a clicking sound, but also a feeling of "stuckness" and pain. If this is the case, you should ask your doctor to examine you in detail and make a diagnosis.
