The reason of muscle soreness is too intense exercise and insufficient oxygen supply, which leads to a large accumulation of lactic acid in muscles. Lactic acid is an acidic substance, which can stimulate nerve endings in muscles and produce pain;
In addition, the accumulation of lactic acid in muscle will cause local osmotic pressure to be too high, thus sucking up the surrounding water and causing muscle edema. This swelling stimulation is also the cause of muscle soreness.
The way to relieve it is to massage yourself a little before going to bed the next night after exercise, and taking a hot bath also has certain effects. All these can accelerate the metabolism of the body, so that the lactic acid accumulated in the muscle is gradually transported away from the blood, and the muscle ache gradually disappears.
