During intensive muscle work operates in the so-called anaerobic mode, i.e. when it lacks oxygen and uses the stored energy. The end product of anaerobic metabolism is lactic acid. If the load is moderate, then the lactic acid safely excreted from the muscles by the blood. But if the load
is intensive, lactic acid does not have time to be excreted from the muscles and starts to irritate the nerve endings. So there is pain.
This is the first type of pain is caused by large muscle loads. It occurs during exercise, and increases as they continue, but gradually goes away after exercise. After physical activity increases blood flow to muscles, increases their tone, the muscles increase in volume.
But there is a second type of muscle pain from stress – lagging muscle pain. It occurs the next Continue reading
