After stopping training, the structure of muscle fibers will change. For the average person, with the increase of age, fast muscle fibers will gradually shrink until the slow muscle fibers are dominant in old age.
After stopping training, the connection strength between nerve and muscle will be weakened, which is one of the reasons for the decline of muscle and strength. Therefore, after being forced out of normal training, we can't completely forget the existence of muscles. We can maintain a certain neuromuscular connection through muscle self-control exercises (focusing on the target muscle group and then actively scaling exercises) or freehand exercises (such as push-ups), which has a certain effect on maintenance.

Precautions:
1, after the fitness, don't stop exercising immediately, let alone squat down and sit down immediately. Because people's blood circulation will accelerate when doing strenuous exercise, if they stop exercising immediately after fitness, or squat down, their heart function will be affected, and even syncope and shock will occur in severe cases.
Don't drink a lot of water after fitness. Because you sweat a lot when you exercise. Sweating will take away electrolytes and moisture, which is easy to cause thirst. If you drink too much water at a time, it will cause water to enter the gastrointestinal tract and quickly enter the blood circulation, which will increase the burden on the heart.
3. Because you will sweat a lot and lose some electrolytes after exercise, you can drink some water rich in electrolytes in moderation after exercise, and your body will be calm.
4. Don't take a bath immediately after fitness. Because the blood circulation of the body is accelerated after exercise, the skin capillaries are dilated. If you take a bath with cold water immediately after exercise, it will shrink the skin capillaries and increase the burden on important organs of the body.
