How is muscle soreness?

Muscle soreness must be the function of lever. If it doesn't hurt, you will feel that you haven't practiced in place. So, today we will talk about the causes of muscle pain:

Lactic acid accumulation

Delayed onset of muscle soreness

The viewpoint of lactic acid accumulation is: during training, muscle cells breathe anaerobically, and lactic acid accumulation occurs during glycolysis, resulting in a sense of pain. ?

But within one or two hours after exercise, lactic acid will basically be removed, so the pain during training and a short time after training is related to lactic acid accumulation. So this is not the cause of pain after exercise.

The viewpoint of delayed muscle soreness is that muscle fiber injury during training stimulates painful nerves and slight inflammation caused by muscle fiber injury.

On the second day after training, muscle aches all over the body are the reason. The principle of muscle training is to tear muscle fibers through weight-bearing training first, and then supplement enough protein to make muscles repair and synthesize, recover excessively, and achieve the purpose of increasing muscles. Mild delayed muscle soreness can be recovered within 24-48 hours, and severe cases can be recovered after 72 hours. This is the real cause of pain after exercise.
