After exercise, the most important thing is to supplement sugar. Chocolate can keep blood sugar stable, relieve hypoglycemia, promote recovery and improve exercise ability, all of which are inseparable from "sugar supplementation". What you consume during exercise is muscle glycogen, that is, glycogen stored in muscle, and then liver glycogen. You only use fat when your glycogen is exhausted, so when your glycogen is completely consumed, your body will produce a lot of lactic acid, and you will feel tired at this time. Therefore, if you supplement sugar during or before exercise, you can delay the appearance of fatigue.

Before exercise, chocolate supplies energy to the body, which makes the blood sugar in muscles and liver in the most saturated state, which is conducive to improving sports performance; After exercise, chocolate can also replenish the energy consumed by the human body in time. From the point of view of sports, chocolate can meet the body's energy in the shortest time because of its high energy consumption and long exercise time.
