The main cause of muscle fatigue is lactic acid build-up. Lactic acid accumulates in huge amounts during static muscle work. When you stand or sit for a long time, your legs and back begin to “numb”. This is also a sign of lactic acid accumulation. But with the dynamic work of the muscles, the acid is split and the muscles do not get tired so quickly. You can walk more than you can stand because your body breaks down lactic acid.
