Why do I feel sore all over after exercise?

With the arrival of autumn, the weather is no longer hot, and more and more people are starting to carry out their fitness plans. Morning jogging, Tai Chi and other exercises can be seen everywhere in the parks in the early morning. The whole body aches after exercise are really unbearable. In fact, this soreness is a normal metabolic phenomenon. The human body will accumulate a certain amount of lactic acid after exercise, and this lactic acid will make us feel sore all over. Below, the editor will explain the reasons in detail.

There are many muscles in the human body, which are composed of muscle fibers and tendons. Each muscle fiber is very thin, but many muscle fibers are tightly packed together. Tendons are located on both sides of muscle fibers. A muscle generally has two tendons, but there are also three or four tendons. Muscles are attached to bones. When a person wants to exercise, the muscle fibers contract or straighten, pulling or pushing the bones to move.

When people do weight-bearing exercises, the muscle fibers in the exercised part will contract or stretch under the force. At this time, some muscle fibers will inevitably break (but don't worry, they can still grow back, these are only a small part of all your muscle fibers). When you rest after training, your body begins to repair itself. Your body will mobilize a large amount of nutrients such as protein to reconnect the broken muscle fibers. However, the rebuilt muscle fibers are not exactly the same as the original ones. Instead, they are thicker and stronger than the original ones. This is an instinct evolved by human beings.

Of course, safety should still be taken into consideration. The intensity and duration of exercise vary greatly for people of different levels, because once an injury occurs, the gain will outweigh the loss. In addition, muscle soreness during weight-bearing exercises and after exercise is not caused by muscle fiber rupture, but by the accumulation of lactic acid in the muscles. Lactic acid is secreted by the human body to protect muscles from injury.

It can be seen from this that most body aches after exercise are very normal physiological phenomena. If there are no special circumstances, there is no need to go to the hospital. In order to speed up recovery, you can have a good rest, eat more protein-rich foods, and do more stretching exercises, which can help you quickly metabolize the lactic acid accumulated in the body.
