Why do muscles hurt

Instruction
With painful sensations in the muscles at certain periods of life, every person came across, including those far from sports training. Even ordinary household chores, in which the muscles receive an inappropriate load, can lead to pain. This is due to a sedentary lifestyle and is particularly pronounced in the spring, when people begin to travel to nature or to the country. Here it turns out that the simplest cleaning leads to the fact that the next day it is simply impossible to straighten. The best way to prevent pain is to exercise regularly.
After a workout, muscles even in trained athletes hurt. This is caused by the formation of lactic acid in them, which appears during training as a result of the contraction of muscle fibers. The pain disappears after the load stops and the blood begins to flush the acid out of the muscles. Since during training the blood circulation increases, the best way to deal with muscle pain is not a state of rest, but active training, no matter how painful they are.Among athletes there is a perception that muscle pain suggests that exercise is beneficial. If such sensations are absent, then it is unlikely that you will be able to build muscle or lose weight.
There is a concept of late pain appearing the next day or the day after the received load. This is due to the fact that the muscles are not accustomed to it, so the degree of intensity of painful sensations depends on how well the muscles are not trained. Within a couple of weeks after the start of training, late pain becomes minimal and begins to bring satisfaction, as it indicates that the training was successful. However, when training changes, muscle pains reappear, because the degree of load and the area of ​​its application changes.
