1. How did this happen?
In fact, it is not difficult to understand that in the early stage of exercise, the muscle system needs to get more energy than at rest to maintain its continuous contraction, so the metabolism is improved and the heartbeat is accelerated, and extra oxygen is needed during exercise, which is provided by shortness of breath.
When you stop exercising immediately, your body has no buffering process. After exercise, the heart beats faster, the capillaries dilate and the blood flow accelerates. At this time, when the exercise stops, the rhythmic contraction of the muscles will also stop. A large amount of blood that originally flowed into the muscle could not flow back to the heart through the contraction of the muscle, resulting in insufficient blood supply to the brain and dizziness.
Therefore, you should not sit or lie down immediately after strenuous exercise, and you should use appropriate methods to restore your body to a calm state.
Second, what should I do after strenuous exercise?
Continue to do buffering exercises.
We can continue to do some buffering exercises. For example, after running 800 meters, the teacher will tell us to jog for a while and then walk for a while. This is actually to give our body a buffer time and let it return to a calm state.
Do some stretching exercises properly.
When our body is warm, static stretching is a way to relax our body. We need to wait until breathing and heart rate are stable before stretching. This can also avoid physical pain after strenuous exercise.
It is necessary to replenish water properly.
It is necessary to replenish water after exercise. Sweat and breathing take away a lot of water. When you are dehydrated, it is bound to be more difficult for your body to recover. Therefore, it is necessary to replenish water to restore the body, but avoid drinking a lot of ice water and aggravate the stimulation to the stomach.
Third, what other things can't be done immediately by exercise?
It is not advisable to take a bath immediately after exercise.
After exercise, many people will sweat and get soaked, so taking a cold bath is what everyone wants to do. Although it is comfortable to take a cold bath after exercise, cold water will stimulate the capillaries of the human body, especially after exercise. Once you take a cold bath after exercise, it will lead to a cold and fainting.
Drink plenty of water after exercise.
Although you should replenish water after exercise, you should also avoid drinking a lot of water. Many people think that sweating after exercise will lose a lot of water and need to replenish a lot of water. Actually, this is not right. At this time, a large amount of water supplement will lead to imbalance of water and electrolyte in the body, which may lead to water poisoning. So slowly replenish water.
Although exercise is good for your health, you should also take protective measures after exercise to keep your body healthy.
