Lead: Many friends are doing aerobic exercise to lose weight, but after a few days of exercise, they are shocked. Because they found that their weight did not decrease, but increased. At this time, they may be completely at a loss or give up exercise. The following small articles are for these friends. After exercise, glycogen in the body increases water retention. Originally, people did not exercise and suddenly gained weight, mainly because glycogen in the body increased and water remained during exercise. Our body consumes a lot of muscle glycogen and liver glycogen, which are the first substances to supply energy during exercise. According to statistics, their total stock in the human body is between 0 g and 00 g, but after exercise, the body generally stores more glycogen than before due to the stimulation of exercise. Before a professional athlete's competition, the common classic diet and exercise arrangements are as follows: practice with high intensity and large amount of exercise day after day before the competition, consume glycogen as much as possible, reduce the intensity and amount of exercise 0- 1 day before the competition, and increase the intake of sugary food. This arrangement can make the glycogen stored in muscle increase by 1~ times than before, and the endurance performance during competition is also better. After exercise, under a reasonable diet, liver glycogen will be supplemented quickly. In the process of replenishment, the body will store a large amount of water according to the ratio of glycogen: water = 1 (This data is based on the widely quoted experimental data of the University of Michigan 1 1 year, and recent research also shows that the correct value of this data should be 1:. ). That is to say, if you store 100g of glycogen in your body, you have to store twice as much water, that is, the total weight reaches 00g. Generally speaking, your weight will increase due to the increase of glycogen and the storage of water.
