Get up in the morning and exercise on an empty stomach, okay? All right! It mainly depends on how you exercise, such as cycling, swimming, playing Tai Ji Chuan, walking and other moderate-intensity sports. Within an hour, I felt a little sweaty, but there was no obvious fatigue. This kind of exercise feels good. Why? After drinking a cup of boiled water in the morning, you should exercise. First of all, you have to clean up the garbage and sundries in your stomach, and then the water will be absorbed by the large intestine and enter the kidney for about fifteen minutes. Because of vigorous exercise metabolism, blood circulation will be accelerated, and some harmful substances removed by the cells of the five internal organs will be excreted through the skin and sweat, and some will enter the kidneys and be excreted from the urine. In addition, it is rarely found that people feel hungry when exercising on an empty stomach, but there is no hypoglycemia reaction. At this time, another one that is more conducive to pancreatic function is called (glucagon gland). Its function is to extract fat conversion energy from human cells to maintain blood sugar level when blood sugar level drops. Especially for patients with moderate or mild diabetes, exercise in this way can activate the functions of "insulin gland" and "glucagon gland" of pancreatic cells and achieve natural health.

It is not good to get up in the morning and exercise on an empty stomach.

You can't exercise on an empty stomach. You should eat something before you go out. Exercise on an empty stomach also has a bad effect on the body. The air in the morning is very cold, which is very irritating to your lungs. Warm up first and exercise regularly every day, and your body will adapt to your habits and anger, which is very important for your body.

Fasting exercise, easy influence, hypoglycemia and other diseases, adverse reactions to the body, and so on.

The above personal views, I hope to help you.

It is not good to exercise on an empty stomach in the morning. At this time, the gastrointestinal tract is very weak and it is easy to cause harm to the body. You can drink warm water before exercise.

Exercise can ensure the vitality of the body, strengthen the body, increase the heart and lung function, and make the young stronger and the old stronger. For patients with chronic diseases such as hypertension and coronary heart disease, it can lower blood pressure and improve cardiac compliance.

China residents' dietary guidelines specifically mention exercise, suggesting at least half an hour of exercise every day. However, less than 40% of China people exercise for half an hour every day and five days a week, so their exercise habits need to be strengthened.

Exercise time Many people exercise after getting up in the morning. This time period can be said to be the first choice for most people. Because there is plenty of time in the early stage, some middle-aged and elderly people may get up at 5 o'clock in the morning and exercise for more than 1 hour to get home, just to cook for their wives and children. This time arrangement is very suitable.

But for diabetics, it is still recommended to exercise after meals. Diabetic friends who use hypoglycemic drugs have the risk of hypoglycemia when exercising on an empty stomach. Moreover, it is suggested that this group of people should carry sugary food with them during exercise to prevent the possibility of hypoglycemia caused by heavy exercise.

It is suggested that office workers get up early, but for young office workers, it is difficult to get up early to exercise because of high blood sugar, tight time and far work place. I'm afraid I can't get up at work, and it's impossible to expect to exercise on an empty stomach or after breakfast. In this case, you can exercise after work, pour a glass of water into the teahouse to exercise, sit in a chair to do aerobic exercise, and stand on tiptoe against the wall for 20 minutes while talking on the phone. These are all exercises.

You can exercise anytime and anywhere as long as you want. You should take exercise as a habit and choose the appropriate exercise time and exercise mode according to your actual situation.

An hour in the morning is worth two in the evening. With people's pursuit of a healthy life, many people who love sports choose to exercise in the morning. But many people don't eat breakfast when they exercise in the morning. Then the question is coming. How about going to exercise on an empty stomach in the morning? What effect will it have on the body?

Here, the author divides exercise into intensity exercise and light exercise.

Let's first analyze the intensity exercise on an empty stomach in the morning.

First of all, we can learn about the changes of blood sugar during fasting exercise.

On an empty stomach, the blood sugar concentration of the human body is low. During exercise, insulin secretion increases and blood sugar begins to rise. After long-term exercise, the blood sugar concentration will drop again, and the blood sugar concentration will be lower. When you continue to exercise, the blood sugar concentration is too low, which is easy to produce hypoglycemia symptoms, such as dizziness, fatigue, brain fatigue, and even cold sweat and pallor. In more serious cases, delirium and coma will occur. Therefore, long-term high-intensity exercise should be avoided on an empty stomach.

Studies have shown that fasting intensity exercise is not suitable for patients with diabetes and hypertension. In the morning, people's blood viscosity is high, and the risk of thrombosis increases accordingly, which is the peak of heart attack. Exercise on an empty stomach in the morning is easy to induce hypoglycemia and even hypoglycemia coma.

Secondly, the content of free fatty acids in the human body will increase during fasting intensity exercise.

Exercise on an empty stomach, in order to ensure adequate energy supply, the human body will decompose excess fat, thus providing more energy. The decomposition of fat is accompanied by the synthesis of free fatty acids. In the process of fasting intensity exercise, the constantly produced free fatty acids are too late to be esterified, thus accumulating in the body. Although fatty acids are the main energy source of human myocardial activity, if the content is too high, acidosis will occur again. Free fatty acids are at a high level for a long time, which easily leads to insulin resistance. Long-term exercise in this environment will lead to arrhythmia and even sudden death [1]. Therefore, it is forbidden to exercise too vigorously on an empty stomach in the morning.

Moreover, fasting intensity exercise is prone to sports injuries.

On an empty stomach, the sensitivity and flexibility of the human body are relatively poor, and it is easy to get hurt if you do high-intensity exercise. At the same time, the stomach is on an empty stomach for a long time, but it still needs to move with the body, which is easy to cause gastroenteritis, appendicitis and other diseases.

What about light exercise?

The answer is yes. Light exercise, such as a short walk, will only raise blood sugar a little, not too low. Some researchers [2] selected 60 patients with type 2 diabetes as the research object, and all the subjects exercised on an empty stomach in the morning (the exercise mode was walking, and the patient controlled the walking speed at 60-90 steps/minute to keep no emotional fluctuation and tension. If the patient has symptoms such as hunger, dizziness and palpitation during the morning fasting exercise, he should stop exercising. The blood sugar levels before and after exercise were compared and analyzed. Results After morning fasting exercise, the average blood sugar level of patients with type 2 diabetes was significantly higher than that before exercise. But no patient had hypoglycemia. Therefore, low-intensity exercise will not have much impact on human health.

In fact, morning is not the best time to exercise. In the morning, the concentration of carbon dioxide is the highest in a day. People who relax for one night in the morning are not fully awake, and it is easy to get hurt if they don't do warm-up exercise before exercise. 3-5 pm is the best time of the day, with high oxygen concentration and low index of inhalable particulate matter. At this time, it is neither empty nor full, and it will not affect eating and rest after exercise, so afternoon is the best exercise time.

To sum up, I don't recommend high-intensity exercise on an empty stomach in the morning. If you want to do high-intensity exercise in the morning, you can choose to supplement some food 30~60 minutes before exercise, and try to choose digestible food, such as dairy products, cereals, fruits, drinks and so on. Do warm-up exercises first, and then do high-intensity exercises.

It is unhealthy to exercise on an empty stomach in the morning. Because when exercising on an empty stomach in the morning, people's stomach has been emptied after a night's diet and digestion, coupled with a lot of physical exercise, the metabolism in the human body is vigorous and energy consumption increases.

Fasting exercise can also lead to insufficient glycogen storage in the liver. Excessive blood sugar consumption without adequate and timely supplementation will make human blood sugar unstable and prone to hypoglycemia. Therefore, dizziness, palpitation, blackness in front of eyes and other symptoms may occur, and even hypoglycemia shock may occur. Especially for the elderly or hypertensive patients, it is not suitable for exercise in the morning.

In the morning, you should eat some digestible and high-energy breakfast first, then rest for about an hour, so that the food can be digested as much as possible before exercising. At this time, the blood sugar concentration in the body is high and the energy is sufficient, which is a good opportunity for us to exercise.

Moderate intensity aerobic exercise for at least 45 minutes is recommended. It is more appropriate for healthy people to have a heart rate of 170- age during exercise. While exercising, eat less greasy and high-sugar foods in your diet, so you can usually lose weight at the same time.

It depends on physical function and the amount of exercise. For me, if the exercise time is within 1 hour in the morning and the intensity of exercise is not very great, I usually just warm up with a glass of water, and then have breakfast after washing. If the exercise time is more than 2 hours in the morning and the exercise intensity is high, I will have breakfast early and start exercising at least 40 minutes after breakfast.

The same question, everyone's physique is different, exercise goals are different, whether to exercise on an empty stomach will naturally be different:

1) For healthy people, different goals have different ways;

A) If it's just basic healthy exercise or weight loss, it won't last long (30-40 minutes, within the shortest hour). It's okay to run on an empty stomach. Just drink a glass of water before running. Running on an empty stomach can also accelerate the consumption of fat and achieve a good fat-reducing effect. Because the first energy consumed during running comes from glycogen in the liver, only when glycogen is consumed can our body mobilize the energy of fat, thus achieving the effect of reducing fat. After a night of consumption, glycogen in the human body will be scarce in the morning, and it can quickly reach the stage of fat consumption during exercise;

B) If you have long-distance running training (running for at least 90 minutes) or want to take part in a marathon, it is obviously impossible to run on an empty stomach. Experienced runners usually get up early and replenish enough energy for breakfast 90 minutes before running (at least before running 1 hour);

2) For people with poor physical function, special attention should be paid, and it is recommended not to exercise on an empty stomach;

For people with diabetes, hypoglycemia, cardiovascular diseases, or elderly people in poor health, it is recommended not to exercise on an empty stomach, which is easy to induce hypoglycemia; It is best to exercise moderately at least 1 hour after breakfast and drink a glass of water before exercise. The body also needs enough water to excrete the garbage metabolized at night through sweat.

In short, exercise is the most important thing for health and fitness!

This is Rorty Run, a leisure runner who runs 17. I will share with you those things about sports life and firmly believe in the power of sports!

Exercise on an empty stomach is definitely not good. After a night of circular metabolism, the body is already in the "empty consumption" period, waiting for the enrichment of breakfast. If you exercise on an empty stomach at this time, it is equivalent to increasing the fatigue operation of various organs and causing physical damage. In short, fasting exercise consumes physical strength and is not good for your health. Get up early, drink a cup of milk oatmeal and go out for exercise. (or have some breakfast)

After a night of digestion, I got up in the morning and my stomach was weak. If I exercise on an empty stomach, it is easy to do harm to my health. I can drink a cup of warm water and eat a small amount of sugary food such as bananas or small pieces of bread, but I don't want to be too full. I don't want to do strenuous exercise, such as running. If it's yoga or something, it can be done without much exercise.

If you are running, drink water 20 to 30 minutes in advance, but don't drink too much water. After running, you should properly replenish water. It is best to eat salt water in moderation, which is more beneficial to your health. After exercise, you must drink more boiled water, eat more soft foods such as pears, apples, milk, sesame seeds and fresh vegetables, and usually cook more foods such as rock candy pear water, Lycium barbarum and Luffa to neutralize this phenomenon, so as to prevent excessive internal heat and increase the protection of mucosa on the surface of esophagus and respiratory tract.
