What happened to faint briefly after running 15

One. It is exercise hypertension. Excessive stress is an acute type of excessive fatigue caused by excessive exercise that exceeds the body's functional capacity.

It is common in middle and long-distance running and other events, and the main reasons for excessive tension are the low level of training of athletes, poor physical function, illness and training after long-term interruption of training, and inadaptability of physiological function and amount of exercise. The clinical manifestations of excessive tension include acute motor disease, cerebral vasospasm, retrograde forgetfulness, acute heart failure and syncope, which are manifested by extreme fatigue, dizziness, nausea, paleness, decreased blood pressure, rapid and weak pulse, etc.

In general, the concentration of blood sugar is relatively constant, and the normal concentration is 100 milligrams of glucose in 100 milliliters of blood, and its fluctuation range is between 80---120 milligrams of glucose.

Hypoglycemia sometimes occurs in athletes during prolonged strenuous exercise training or competitions due to the high consumption of blood sugar in the body. Athletes in competitions such as long-distance running, marathon, long-distance swimming, and cycling can develop exercise-induced hypoglycemia. Because our body's tissue cells can not store sugar, can only be taken from the blood during exercise, so it often becomes a state of short supply, some people have done research, found that when the blood sugar drops to 50 mg%, there will be dizziness, fatigue, fast pulse, hunger, irritability and other symptoms.

When the blood sugar is below 50 mg%, symptoms such as memory loss, confusion (for example, athletes can turn in the opposite direction to run during competition), and syncope will occur.

Because one of the advantages of sugar is that it consumes less oxygen when oxidizing in the body, it can quickly provide energy to meet the needs of exercise, which is of great benefit to events such as marathon running, long-distance swimming, etc.

In order to prevent the occurrence of exercise-induced hypoglycemia, it is strictly forbidden to participate in heavy exercise training or competitions on an empty stomach; For athletes in sports that are long and consumed, there should be plenty of sugar before the competition, and sugary drinks should also be provided during the competition.

It may be related to dehydration after exercise, pay attention to water and sugar before and after exercise, and hypoglycemia can also cause related symptoms.

It was a short-term lack of blood supply to the brain, and I had to walk slowly for ten minutes after running, because the lung capacity was very large when I was running, and you would be like this when you suddenly stopped, I knew that I was in junior high school when I was in a sports competition, I almost didn't faint, I felt dizzy and dizzy at that time, I wanted to stop and rest, but the teacher didn't want to say that it was not good to let me walk, but it was really good to take a break, so pay attention to it in the future After exercising last night, I must take a walk, Give your lung capacity and heart relief.

Syncope is caused by a lack of oxygen to the brain, which leads to a lack of oxygen in many parts of the body after a lot of exercise. It is recommended not to bend down immediately after running, but to walk, even if it is uncomfortable. Long-distance running should adjust your breathing and distribute your physical strength reasonably.

This is a physiological phenomenon that varies from person to person, and the difference in the prespinal is manifested in some obvious reactions and some not.

1. Frequent activity of the heart function is good and adaptable, so the recovery is fast, unless the most strenuous activities usually restore the process of regret is not obvious.

2. Flat is the poor reserve capacity and poor adaptability of the inactive cardiac function, and the performance is obvious.

Running is a very demanding exercise, you can't stop all at once when you have just finished running, and it takes a process to go from movement to stationary.

When a person is running, the muscles of the lower limbs contract and relax nervously, so that the capillaries in the muscles are greatly expanded, and the amount of blood flowing through the muscles of the lower limbs is also greatly increased than usual, and the muscles of the lower limbs contract and relax rhythmically, which plays a squeezing role in the blood vessels of the lower limbs and helps the blood flow of the lower limbs back to the heart.

However, if you stop abruptly during running, it will lead to a decrease in blood supply to the brain, causing dizziness and other undesirable phenomena, in order to prevent this phenomenon, you need not to stop suddenly during running, do not stand still suddenly after running, you should continue to relax jogging, walking, and gradually transition to normal.

There are many possible reasons, and it is related to your eating habits and health status!

Don't drink a lot of water before running, don't eat too much, it will increase the burden on the stomach, the blood circulation around the body will speed up when running, the blood supply to the stomach is insufficient, and there will be a feeling of vomiting after running. It can cause dizziness symptoms!

Also, don't open your mouth to breathe when running, let the cool air directly into your stomach, and your stomach will hurt. The correct way is to put the tongue on the upper tooth chamber to let the air cushion from both sides of the tongue, and the stomach will not hurt when it is warm.

The correct breathing method can be learned: inhale, inhale, inhale, exhale and exhale as you run at the step point. Inhale three breaths, exhale three breaths, and cycle.

In addition, dizziness may be caused by cold, cervical spondylosis, anemia, high blood pressure, etc., and the timing and quality of rest are not good.

Instantaneously, the brain does not have enough energy, and the typical blood sugar cannot meet the brain's needs in time, so the brain rests.

My brother has also had, you may be anemic, it is best to check it, but generally after strenuous exercise, due to the acceleration of blood circulation, after the movement of people with thin blood vessel walls stops, the blood can not return to the body in time, resulting in excessive cerebral congestion and syncope, generally after a period of rest, it will be fine, it is best to go to the hospital to see! Hehe! Can I give points?

I am a fitness coach, if a healthy person, it is very difficult to faint, it is not easy to achieve brain lack of oxygen and lack of energy, and it is not easy to exercise, because the body has reasonable coordination, it is recommended to perform the exercise tasks arranged for yourself, but also for your good, what to be afraid of, think about the Red Army 25,000, if it is really necessary to faint, or use a feign. I still hope that you can calmly complete the task of exercising and exercising, the motherland and the people are watching you, and the country does not want to train you to become a person who evades responsibility, and hopes that you will become a brave warrior.

If you have any fitness questions, you can ask this coach to answer.

Skipping breakfast and running out of energy can lead to fainting.

If you run too many laps and your physical strength is overdrawn, you will faint.

When running, keeping too nervous and not breathing well can lead to fainting.

When the race reached the finish line, he accelerated too fast, resulting in insufficient oxygen supply and sudden fainting.

Don't eat for a whole day, then don't sleep for 2 nights in a row, don't drink water! Guaranteed to work.

It's a scary question, but you're asking how to avoid fainting while running.

The possibilities that come to mind are: one is high-intensity exercise when you have low blood sugar (such as diarrhea and skipping breakfast), and the other is continuous exercise under the scorching sun when you are short of water.

Generally, people with normal body are not easy to run and get dizzy, unless the physical condition is not good and the environment is harsh, so there is no need to worry too much, but avoid challenging the limits of the body under the scorching sun. If you are feeling dizzy, immediately move him to a cool place, loosen his clothes, and drink light salt water and plain water. If you faint and are unconscious, then quickly dial 120, and if you don't breathe during the period, of course, you need artificial respiration to save you.

See if you want to get dizzy, run at maximum speed, and if you want to get dizzy, this is the best way.

Physical reasons, it may also be that the breathing rhythm is too chaotic and there is a lack of oxygen.

Analysis:

Depending on this situation, two causes are generally considered, transient cerebral insufficiency or cardiac arrest.

Malnutrition, poor physical fitness due to not exercising regularly, or not being prepared for a warm up while running
