To lose weight, you must exercise moderately and not overdo it.

        In recent years, there has been a craze for "aerobic dance" in Europe and the United States. Training rooms with coaches have been set up in various gyms or clubs in the city. Men, women and children of all ages dance feverishly to the strong rhythm of the melody. While people are immersed in the joyful dance, some experts point out that aerobic exercise will shorten people's lifespan. They believe that inhaling too much oxygen is not good for the body. Aerobic exercise is the active inhalation of oxygen, so it has an impact on human lifespan.

　　Aerobic exercise and anaerobic exercise

　　The so-called aerobic exercise is relative to hypoxic exercise. Aerobics stands for brisk exercise and includes walking, bicycling, tennis, golf, aerobic dance, long-distance swimming, and more. Hypoxic exercise represents strenuous exercise, including short-distance running, weightlifting, high jump, long jump, javelin throwing, discus throw, sumo wrestling, etc.

　　The cells of our body take in oxygen through respiration and Grape Sugar nutrients combine to produce adenosine triphosphate (ATP). Muscles rely on ATP as kinetic energy to contract. Aerobic exercise uses oxygen to produce ATP while exercising, so we won't feel very tired and can continue exercising for a long time.

　　Aerobic exercise has many benefits

　　Aerobic exercise has many benefits: first, it can exercise heart. Aerobic exercise involving repeated flexion and extension of the arms or legs appropriately increases the load on the heart and prevents the decline of heart function. Second, prevent heart disease. If you continue to do aerobic exercise, the capillaries in the heart will increase, which will improve the oxygen supply to the myocardium and prevent myocardial infarction. Even if you suffer from myocardial infarction, the probability of being out of danger is high. It also lowers cholesterol and softens blood vessels. This is difficult to obtain during hypoxic exercise. Third, it is suitable for losing weight. If you continue aerobic exercise for a long time, the muscles will not become thinner, but the fat will be reduced. Fourth, it is a safe and feasible exercise. Especially for the Chinese elderly , can prevent sudden death.

　　Is aerobic exercise beneficial at all?

　　In this way, aerobic exercise is a form of exercise that is beneficial to the body healthy movement, however, this is not necessarily the case.

　　Relevant experts have conducted two animal experiments showing that aerobic exercise shortens lifespan. The first is the longevity of hibernating voles, which is the latest paper published by Professor Hubert of Harvard Medical University in the United States. He divided the voles into three groups that hibernated well, barely hibernated, and something in between to compare their lifespans. The results are very good. The longest life span of hibernating voles is 1600 days, while the longest life span of non-hibernating voles is only 1100 days.

　　Hibernation can be said to be the opposite phenomenon to aerobic exercise. As body temperature drops, oxygen consumption is greatly reduced. On the contrary, excessive oxygen consumption can obviously shorten life span.

　　Another experiment is the short life span of flies that exercise a lot, which was recently studied by Dr. Suhar of the University of Southern Mesodates in the United States. He raised houseflies in large containers (27,000 cubic centimeters) and small containers (250 cubic centimeters) and compared them. As a result, the house flies in the large container were very active and consumed 11.2 microliters of oxygen per milligram of body weight per hour, while the house flies in the small container consumed 7.6 microliters. House flies in the large container that consumed "a lot" of oxygen lived for 33 days, while those in the smaller container lived for 78 days. This shows that people who exercise more and consume more oxygen have shorter lifespans.

　　Research also shows that aerobic exercise can lead to cancer, arteriosclerosis, Alzheimer's disease, and can also be said to shorten life span.

　　In short, when excessive exercise becomes a burden, aerobic exercise becomes "hypoxic exercise". Only by exercising according to your physical condition can you be happy and live longer.

　　Regarding the frequency of fitness, the American College of Sports Medicine recommends that normal people should exercise 2 to 5 times a week. If you have no fitness habit before, you should start with a small amount, twice a week, and then slowly increase to three or four times. A common mistake that beginners make is that when they start working out, they are very enthusiastic and want to achieve results as soon as possible, so they exercise every day at once, and the intensity of each exercise is also very high. This often leads to overtraining, and symptoms such as fatigue, insomnia, and excessive body aches will appear in a short period of time.

　　Then it will stop again. In fact, what we should realize is that fitness is a long-term habit. If you want to have a strong body, you should insist on fitness throughout your life. It takes months or even years of persistence to achieve optimal body shape and health. Step by step is the best solution.

　　The average person consumes about 15 kcal for one minute of jogging (the heavier you are, the more you consume), and one kilogram of fat consumes 3,500 kcal. If you jog for 30 minutes every day, you can lose one kilogram a week without changing your diet.

　　Of course, this is just a theoretical calculation. In fact, you will eat a little more after exercise. The weight loss rate recommended by experts is half a kilogram a week, so that the weight lost is not easy to rebound.

　　In order to save time, many people go directly to high-intensity aerobic training without warming up. If this is the case, because the cardiovascular system and lungs have not yet entered the state, the body temperature is relatively low, and the flexibility of the muscles is not good, it is easy to cause damage. In addition, you will feel better before exercising after warming up, and the exercise time can also be longer. In other words, if you exercise without warming up, you will tire more easily.

　　Warming up generally refers to using low-intensity aerobic fitness to gradually get your body into a better state and slowly increase your body temperature. heart rate Increase and breathe evenly and faster. Blood circulation is also faster, so that oxygen and nutrients will be transported to the heart and muscles to prepare for your exercise. An important sign that the purpose of warm-up activities is achieved is that the body starts to sweat slightly. The warm-up time is 5 to 10 minutes. When it's cold, warm up longer and wear more clothes.

　　Relaxation has the same effect as warming up. During exercise, blood circulation is accelerated and the amount of blood is increased, especially in the limbs. If you stop exercising immediately, blood will accumulate in the lower limbs and cause unnecessary burden on the heart. In severe cases, it can affect the blood supply to the brain and even cause dizziness and dizziness. Therefore, after achieving the purpose of exercise, there should be 5 to 10 minutes of relaxation, that is, gradually reducing the intensity of exercise and slowly returning to a quiet state.
