Muscle soreness is a normal physiological manifestation. After strength training or an unsuitable exercise (excessive exercise or new exercise), people often have obvious muscle soreness and discomfort. These symptoms will disappear naturally after a period of rest, and when you do the same exercise again, the symptoms of muscle pain will be obviously alleviated or not produced. Due to muscle soreness caused by training, you can take some sports nutrition supplements to speed up the recovery and compensation of sore muscles. Such as glutamine.
There is also muscle strain or injury caused by improper exercise. Muscle or ligament strain can cause large-scale lesions of skeletal muscle, such as cell degeneration and cell necrosis, which must be solved by medical means.
