Causes of muscle pain from strenuous exercise

Sports are becoming more and more popular nowadays. This is because sports not only make people have a healthier body, but also help women lose weight and build solid muscles for men. Therefore, doing sports is really the best of both worlds. However, for those who have just started exercising, they will feel muscle pain after strenuous exercise and body aches after waking up. Why is this?

People who do not exercise regularly will experience local muscle pain after strenuous exercise, which is related to the energy metabolism inside the muscles. Various forms of human body movement are mainly completed by muscle contraction. Muscle contraction requires energy, which is mainly provided by the decomposition of carbohydrates in muscle tissue.

In the presence of sufficient oxygen, such as when the human body is at rest, the carbohydrates in the muscles are directly broken down into carbon dioxide and water, releasing a large amount of energy. However, when the human body is engaged in strenuous activities, skeletal muscles urgently need a large amount of energy. Although respiratory movement and blood circulation are greatly enhanced at this time, they still cannot meet the muscle tissue's demand for oxygen, causing the muscles to be in a state of temporary hypoxia.

As a result, sugars break down into lactic acid, releasing relatively little energy. When lactic acid accumulates in the muscles, it stimulates the nerve endings in the muscle mass and produces a feeling of soreness. The accumulation of lactic acid increases the osmotic pressure in the muscles, causing the muscle tissue to absorb more water and produce local swelling.

For people who exercise regularly, their muscles can get more sufficient oxygen during exercise, and less lactic acid is produced by the breakdown of sugars, so there will be no obvious pain in the muscles.

The above analyzes the causes of muscle pain after strenuous exercise. After reading it, everyone will have some understanding of this phenomenon. In fact, this is also a normal phenomenon. Although exercise is a good thing, unscientific exercise will hurt yourself. Therefore, you should exercise more often, do warm-up activities before exercise, and remember to do some relaxing activities after exercise, which can relieve muscle pain.
