"Liver sugar and blood sugar" in human body is mainly converted from starch. Anaerobic training, strength training and high-intensity training all rely on timely consumption of liver sugar and blood sugar to replace energy. The energy stored inside the human body is also limited, only about.
About 1500 calories, so it needs to be replenished constantly. The body full of fat energy cannot be used in time, and low-intensity aerobic exercise will use fat energy. Another energy is that protein exists in muscles, and everyone doesn't want to run out of muscles after practicing for half a day. Therefore, if you don't eat starch, you won't have the strength to do it, so the training efficiency is naturally poor and you can't achieve the purpose of training.
