The principle of exercise slimming The energy required for muscle exercise comes from two parts: sugar in the body and sugar in fat: when people do strenuous exercise for a short time, a large amount of sugar in the body is broken down to generate energy for muscles. Body fat: When people exercise for a long time, the heat provided by sugar in the body is far from meeting the needs, so body fat is oxidized and decomposed to generate heat energy for human use. Anaerobic exercise When people do strenuous exercise for a short time, the human body is in a state of temporary hypoxia, and a large amount of sugar in the body is decomposed to generate energy for muscle use. So anaerobic exercise does not consume fat. Aerobic exercise When people do endurance exercise for a long time, the heat provided by sugar in the body is far from meeting the needs. By increasing the supply of oxygen, the fat in the body is oxidized and decomposed, and heat energy is generated for human use. It is best to use long-term endurance exercise to lose weight, such as walking, jogging, swimming, cycling, aerobics, dancing and so on. The mechanism of losing weight by exercise is: (1) The main energy of human exercise comes from sugar and fat. During aerobic exercise, the utilization of free fatty acids and glucose in blood is increased by muscles, which leads to the release of a large number of free fatty acids from adipocytes and makes them thinner. At the same time, excess blood sugar is consumed and cannot be converted into fat. (2) When people exercise, the secretion of adrenaline and norepinephrine increases, which can improve the activity of lipoprotein enzyme and accelerate the decomposition of chyle and low-density lipoprotein rich in triglycerides, so it can reduce blood lipid, increase high-density lipoprotein and finally accelerate the action of free fatty acids. (3) People who often engage in endurance exercise improve the sensitivity of insulin receptors on muscle cell membranes and enhance their ability to combine with insulin. Insulin has a strong inhibitory effect on lipolysis, which can reduce the increase of catecholamine and growth hormone, and finally accelerate the action of free fatty acids. (4) Obese people have low metabolic rate and less energy consumption at rest. After systematic exercise, the functional level is improved, especially the enhancement of cardiac function and the improvement of endocrine regulation, so that the metabolic level and energy consumption of obese people are increased. (5) Obese people often suffer from normal loss of appetite and reduced food intake after proper intensity of exercise training, thus limiting calorie intake, resulting in negative balance of energy metabolism and reducing fat. Correcting the five misunderstandings of exercise to lose weight In short, the basic principle of weight loss exercise is: consumption is greater than supplement. At the same time, sports science research also found that even if you lose weight successfully, your diet and exercise should still become a part of your personal living habits, so as to keep in good shape all your life. If you stop at any time, you will easily gain weight again. For obese people, losing weight is a protracted war with only the beginning and no end. It is best to exercise regularly for a period of time every day, plus low-calorie food with balanced nutrition. Therefore, whether you are willing or forced, you should be mentally prepared, that is, once you participate in the weight loss exercise, it means changing your original lifestyle, and you must persevere and carry the weight loss exercise to the end!
