What are the causes of muscle soreness without exercise?

The symptoms of muscle soreness are very common in people's lives. Muscle soreness can cause many problems and make people's bodies very painful. Moreover, many people experience such symptoms without exercising. Therefore, most people are more concerned about the occurrence of this phenomenon. Let's take a look at the reasons for muscle soreness without exercise. I hope everyone can understand it.

Muscle soreness: acute and chronic soreness. Acute soreness: Muscle pain that occurs within a relatively short period of time during or immediately after exercise. Acute soreness is related to the interruption of blood flow when the working muscles exert force. In the case of ischemia, metabolic products cannot be cleared and accumulate in the muscles, thereby stimulating the pain receptors. Full recovery occurs within about a minute after stopping exercise. Chronic muscle soreness often occurs between 24-48 hours after exercise. The degree of chronic muscle soreness is related to the form of muscle contraction. Eccentric contraction is most likely to cause chronic muscle soreness, while isometric contraction is the least obvious. When chronic muscle soreness occurs, muscle strength decreases significantly.

Causes of chronic muscle soreness:

1. Tissue traction theory: caused by muscle damage.

2. Muscle spasm theory: caused by repeated muscle cramps.

3. Connective tissue theory: It is caused by injury to the connective tissue of the muscle (such as tendons). In fact, chronic muscle soreness is caused by muscle damage and division.

Ways to avoid muscle soreness:

1. Muscle stretching exercises (performed in a static manner).

2. The principle of gradual load increase: The overload principle of muscle training makes it easy for muscles to be injured. Only by combining the principle of gradual load increase and slowly improving the quality and quantity of muscle training can injuries be effectively avoided. * Appropriate supplementation of vitamin C is recommended, but further analysis and confirmation is needed.

Delayed onset muscle soreness refers to muscle soreness that occurs several hours to 24 hours after exercise. The muscle soreness usually lasts for one to three days. The causes of delayed onset muscle soreness are nothing more than muscle injury, muscle spasm or connective tissue abnormalities. However, it is generally believed that connective tissue abnormalities are the biggest cause of delayed onset muscle soreness.
