The season of the year lies in spring, and the season of the day lies in the morning. It is true that morning exercise is good for our health, but it is not a good time to lose weight. The best time to lose weight is after dinner and before going to bed. It's best to eat less and exercise properly at night. Eat more foods rich in protein, and it will be effective if you stick to it! The best time to exercise every day. Many foreign scholars have revealed that the state of human body's ability changes during the day and night. 8: 00-12: 00 and 14: 00-17: 00 every day are the times when the speed, strength and endurance of chickens are in the best state. If you do physical exercise and sports training during this time, the effect will be better. But from 3: 00 to 5: 00, 12 to 14, it is in a relatively low state. If you are engaged in sports during this time, you are easy to get tired, and when the "load" is too large, the probability of sports injury is high. This shows that people should choose the best time to engage in sports activities according to the possibility of objective conditions in order to receive good fitness and training results. As far as health is concerned, it is effective to start exercising at any age. Exercise more when you have time, but exercise less when you have no time. Just move, even if it's just a trick. When is exercise good? This is a controversial issue. It is said that plants breathe out a lot of carbon dioxide after a night of metabolism, so the concentration of carbon dioxide in the Woods is relatively high in the morning, and some dust is floating in the air, which is not good for people's health. In addition, people's blood pressure is relatively high in the morning, which is prone to problems. In fact, whether to exercise in the morning depends mainly on the purpose of exercise. If it's to lose weight and increase the memory of motor skills, morning is good. When people wake up in the morning, they have consumed almost all the energy they ate last night. At this time, not eating and not exercising will lead to a result-"burning" fat. There is still some glycogen in the liver because there is no energy in the morning. When the concentration of these glycogen is reduced to a certain extent, fat "burning" will become the dominant way of energy supply, thus making it possible to lose weight. Therefore, exercise in the morning has special benefits for losing weight and preventing fatty liver. Besides, it is easier for people to learn aerobics, ballroom dancing and Tai Ji Chuan in the morning than at other times. Therefore, the health benefits of morning exercises are more in a sense. The ancients paid attention to "smelling chickens and dancing", and fitness was generally chosen in the morning. As for the carbon dioxide in the air in the morning, the serious pollution is not the main reason. In fact, the pollution of automobile exhaust during the day is also very serious, which will release lead, heavy metals and some chemical wastes, such as benzene. Blood pressure is high in the morning and can be adjusted by drugs. Therefore, when is the best time to exercise is not absolute. It also varies from person to person. Whether in the morning or afternoon, you should exercise moderately. As far as health is concerned, it is effective to start exercising at any age. Exercise more when you have time, but exercise less when you have no time. Just move, even if it's just a trick. Exercise should vary from person to person and step by step. Don't be too intense at first, and then gradually increase the amount of exercise, not just simple activities, to solve problems. In addition to heart rate, there is also the simplest way to measure whether exercise is excessive. If you can't breathe during exercise, it means that you exercise too much. No matter what exercise you do, especially middle-aged and elderly people, it is suitable for doing full-body activities for physical exercise. For example, swimming, running, walking, these can be, gymnastics can also be. But it must reach a certain amount. There is a saying of "three, seven". The so-called "three" means that the time for each exercise should be more than 30 minutes. If the exercise time is less than 20 minutes and the intensity is not too great, I am afraid that at most, I will consume a little blood sugar in the blood circulation, which will neither lose weight nor consume excess fat accumulated in the body. It should be noted that it is definitely not good to exercise immediately after a full meal, because your blood is concentrated in your stomach to digest food after a meal. When do you exercise in the morning, noon and evening? Of course, your exercise time is limited by work and study. However, if you can choose at will, is there an optimal exercise time? The expert said: Yes. But this time is largely up to you. In recent years, scientists have been exploring the relationship between biological clock and exercise in order to find a time that can consume the most fat every day. The results show that the change of body temperature will affect the quality and effect of exercise to the greatest extent. In other words, when exercising, the higher the body temperature, the better the exercise effect. Usually the body temperature is the lowest within 1~3 hours before getting up, and it will rise to the highest in the afternoon. Therefore, it is safe to say that the best time for exercise is in the afternoon. During this time, your muscles are warm, your physical strength is abundant, your heart rate is stable and your blood pressure is low. But scientists also warned that you should not think that the laws of the biological clock can determine everything, and the best time for you to exercise depends on whether you can do it on time. So schedule your time at a time that will not affect your normal work, and don't always think about your body's biological clock. You'd better ask yourself two questions before deciding when to exercise. First of all, what's your schedule? Are you busy in the afternoon or evening? Is morning exercise more suitable for you? Or, do you need to adjust the amount of exercise in the morning, afternoon and evening? Second, when do you feel at your best? Do you have any difficulty getting up in the morning? Are you the kind of person who procrastinates? In that case, sports will definitely be ranked last by you. Maybe you feel more active in the morning, in the best condition in the morning, and willing to exercise, but have you ever thought that you still have a whole day to do and you need more energy to deal with the affairs of the day? Ironically, morning exercise has one of the biggest advantages over afternoon exercise: it is easy for people to stick to it. Because there will be no conflict in the exercise schedule at this time, people will not be distracted by other things. Persistence is a very important influencing factor of exercise. However, no matter what time you choose, you should follow the following suggestions to make your exercise more effective and interesting. Exercise in the morning: 1, and put away the clothes to wear the next day that night. When the alarm clock rings, you can jump up without looking for clothes and shoes everywhere. Set two alarm clocks, one beside the bed and the other in the room to prevent you from being lazy. Step 3 find a partner. It's usually fun to exercise with your partner, so why not add this to your exercise plan? When you want to be lazy or give up, your partner will remind you and urge you to stick to it. Exercise in the afternoon or evening: 1, determine the exercise time and stick to it. Don't let other things distract you and give up exercise. Try to arrange the time on Sunday night. If there are any small adjustments, it is ok, but it must not affect your goals. If you exercise outdoors, you should pay attention to safety. Prevent heatstroke and dehydration in summer. Drink more water. Exercise and fitness have become a global craze. Even during the lunch break at noon, there will be office white-collar workers going to the nearby gym to exercise. Is this kind of exercise good for your health? When is the best time to exercise in a day? According to foreign reports, some sports and nutrition experts have conducted a comprehensive study on this. First, exercise should be avoided for a period of time after meals. Because after-dinner sports meeting: 1. * * * Stomach and intestines: After a full meal, exercise will bring a mechanical sensation to the stomach, making the dissolved substances in the stomach vibrate from side to side, which may cause vomiting, stomach cramps and other symptoms. 2. Disordered blood flow distribution: After a full meal, the digestive organs need a lot of blood for digestion and absorption, and the muscles of the whole body also need a lot of blood to participate in exercise, so it will seize the blood of the digestive organs, leading to disorder of digestion and absorption, which not only affects the exercise effect, but also harms the body. 3. Affect the exercise effect: After eating, the parasympathetic nerves in the body are easily inhibited. At this time, if the body wants to exercise, the exercise effect will be discounted. 4. Increased insulin secretion after meals can inhibit lipolysis, and the energy source is limited. Because there is less fat decomposition, it is not appropriate to carry out weight loss exercise at this time. The study found that high-intensity exercise can be carried out two hours after meals; Moderate exercise should be arranged one hour after meals; It is most reasonable to do light exercise within half an hour after meals. According to this, several optimal exercise periods can be deduced: morning period: from morning to morning before breakfast; 2 hours after breakfast to afternoon before lunch; From 2 hours after lunch to before dinner in the evening; From 2 hours after dinner to early before bed. Exercise in each period has advantages and disadvantages. For example, in the morning, when the human body performs strenuous exercise, it can excite the sympathetic nerve. This rapid change will cause a series of changes in the body, affect the mental state of the whole day, and be harmful to health. In addition, at this time, blood sugar is at a low level, and exercise consumes a lot of blood sugar, which easily leads to hypoglycemia. Afternoon sports are influenced by objective factors such as work, work and housework. Modern sports physiology research shows that the highest and lowest points of human physical strength are controlled by the "biological clock" of the human body and generally reach the peak in the evening. For example, the lowest point of oxygen absorbed by the body is at 6 pm; Heart beating and blood pressure regulation are most balanced between 5 pm and 6 pm, while the body's sense of smell, touch and vision are also most sensitive between 5 pm and 7 pm. So, on the whole, the effect of exercise at night is better. In addition, the hormone activity of the human body is also in a good state between 4 pm and 7 pm, and the body's adaptability and nerve sensitivity are also the best. Therefore, experts advocate evening exercise, but in the evening time, we should pay attention to the intensity of exercise, otherwise too high intensity will excite sympathetic nerves and hinder sleep.
