Fun run has a better weight loss effect. According to epidemiological investigation, the best time to lose weight by running is at night 19:30-20:30, when the effect of losing weight by running is the best. Because the basal metabolic rate of the human body is low at this time, it will obviously improve the basal metabolic rate in the body after running, and improving the basal metabolic rate will play a better role in losing weight.
Advantages and disadvantages of running in different time periods
The benefits of running in the morning: improving nerve excitability. Many of us have been taught since childhood that we should exercise for a day in the morning. In fact, moderate and appropriate morning running has been highly praised by many people, because it can excite sympathetic nerves, not only make the body flexible and thinking agile, but also help to improve work efficiency.
Disadvantages of morning running: environmental problems are the most serious. A study by Yamaguchi University shows that early morning is the peak time of heart attack, so running in the morning will do harm to the hearts of many elderly people. The experiment also shows that the adrenaline secretion of running in the morning is 2 to 4 times higher than that of running in the afternoon and fun running. In addition, blood sugar is at a low level in the morning, and high-intensity running will consume a lot of blood sugar, which will easily lead to hypoglycemia symptoms. Moreover, the environmental problems are the biggest in the morning, especially before sunrise, when the concentration of carbon dioxide in the air is high, which is not suitable for sports with high oxygen consumption. In addition, during this period, an inversion layer will appear in the near-lower atmosphere over the land. This temperature layer is like a hood, which allows more smoke, impurities and even harmful chemicals such as alkali and benzene to gather under it. These are harmful to the health of runners.
Benefits of running in the afternoon: the body is in the best condition. Dr. Thompson from the American College Sports Medicine Association (ACSM) found 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 afternoon near the evening. For example, the lowest point of oxygen absorption by the body is at 6 pm; The adjustment of heart beating and blood pressure is most balanced between 5 pm and 6 pm. At this time, most people are calm and stable, full of physical strength, and the flexibility, coordination, accuracy and adaptability of technical activities are at their best, so running at this time is also a very good choice. Therefore, it is suggested that the best time for running is from 4 pm to 6 pm. Even in the theory of traditional Chinese medicine, it is pointed out that the bladder meridian runs at 4 pm. On the one hand, drinking water is good for detoxification, on the other hand, running and sweating are also good for health.
Disadvantages of running in the afternoon: busy with work, it is difficult to get out. For most runners, this is a busy time, and it is difficult to have time for running exercise.
Benefits of fun running: A good way to lose weight For all people who have no time to exercise during the day, fun running has become the best choice. Japanese experts found through experiments that, contrary to morning running, the number of platelets in fun run decreased by 20%, which greatly reduced the risk of vascular embolism. After fun running, the brain secretes more melatonin and growth hormone during sleep, which can promote the growth and development of teenagers, improve the immunity of adults and promote sleep. According to a research report published by the Clinical Research Center of the University of Chicago, hormones, the key substances of human metabolism, have the strongest response to physical exercise at night and at night. This also means that fun running is a good way to lose weight.
Disadvantages of fun running: it is easy to get sick because of air quality problems after the evening rush hour. In the view of Chinese medicine, sweating is vulnerable to wind and evil, and excessive exercise at night consumes yang, which is not conducive to human health. Huangdi Neijing records that "quietness is the principle of physical rejection, although there is strong wind, it can be harmful", which means that people's skin is closed in a calm state, and even if strong wind blows, it can't hurt the body. However, when people are running, blood flows to the limbs one after another, which makes the temperature rise and the acupoints open after being heated. Blowing at this time, exogenous cold and evil can easily get in, laying a hidden danger of the disease.
