Why do muscles feel sore after exercise?

I don’t know if you have ever encountered this situation, that is, after doing some unfamiliar exercises, or after some excessive exercise, you will feel muscle soreness. This is especially true for those who do not participate in physical exercise very much, or those who have given up exercising for a long time after a period of time. This kind of muscle soreness will be particularly prominent after exercise. So what causes muscle soreness after a workout?

It is generally believed that muscle soreness is caused by insufficient oxygen supply during muscle exercise, and the anaerobic breakdown of glycogen releases energy for muscle contraction. During the anaerobic breakdown of glycogen, a metabolic product called lactic acid is produced. If it is not cleared in time, lactic acid accumulates in the muscles and blood. Muscle soreness can occur due to the influence of tissue ischemia and hypoxia, acidic substances, damage to the muscles themselves caused by exercise, or muscle spasms.

Muscle soreness is a physiological phenomenon that occurs during exercise. Usually, with proper rest and adjustment, it will disappear automatically after a few days. Don't mistake it for a pathological condition, and don't stop exercising because of muscle soreness. As long as you keep exercising regularly and maintain an appropriate amount of exercise, you won't have muscle soreness. Because people who exercise regularly can improve the body's ability to metabolize acidic substances. Therefore, muscle soreness is usually more obvious when you first participate in physical exercise. People who exercise regularly sometimes also experience muscle soreness when the amount of exercise increases than usual, but the soreness reaction is relatively subtle and not necessarily fast.

What to do if you have muscle soreness after weight loss exercise? The way to avoid and reduce muscle soreness is to increase the amount of exercise step by step from small to large, from slow to fast, when you first start practicing. In addition, do adequate warm-up before each exercise. When muscle soreness occurs, the movement of some muscles can be appropriately reduced, and the method of changing limb exercises can be used to relieve some muscle soreness and eliminate fatigue. After exercise, you should do some clean-up activities to relax your muscles. You can also use a towel to apply partial heat or massage the sore muscles, which will help relieve muscle soreness.

According to the time of muscle soreness after exercise, muscle soreness can generally be divided into immediate and delayed pain. As the literal meaning suggests, immediate pain means pain that can be felt immediately after exercise, but the pain in this case usually comes and goes quickly; but delayed pain may be delayed for two to three days, or even longer.
