Exercise, health, science and reason
Content 1. If you want to be healthy, you must first know the principle of healthy exercise prescription. The so-called exercise prescription, like a prescription given by a doctor to a patient, is to scientifically and reasonably compile the exercise mode, exercise time and intensity according to the individual's physical condition, so as to guide people to improve their physical fitness and promote health through exercise. Exercise prescription consists of the following four elements.
1. Reasonable exercise: Choose the exercise that suits you best according to your physical condition, educational level and economic situation. Don't blindly follow others and imitate others aimlessly.
2. Reasonable exercise intensity: According to the individual's physical condition, the intense intensity of exercise should be moderate. Don't be too hasty and exercise too much, which is not only useless, but harmful.
3. Reasonable exercise time: The time for each exercise should not be too short or too long, and it should be moderate.
4. Reasonable exercise frequency: The number of exercises per week should be appropriate.
Second, to be healthy, there must be a scientific method.
Among them, exercise can be divided into aerobic exercise and anaerobic exercise according to the most common metabolic patterns.
Aerobic exercise is a lasting exercise. During the whole exercise, the oxygen inhaled by the human body is roughly equal to what is needed. Low-intensity, rhythmic and long-lasting sports are basically aerobic sports, such as walking, jogging, long-distance slow swimming, cycling and dancing. Aerobic exercise is the most effective and scientific method to keep physical and mental health.
Walking: When walking, people will hold out their chests and abdomen, strengthen their leg muscles and make their bodies more flexible, coordinated and beautiful!
Dancing: Daily fitness is boring and monotonous, and it is difficult to arouse people's interest. Therefore, it is more difficult to persevere. On the contrary, rhythmic exercise is more beneficial to the body than leisure exercise, which is easier for people to accept and enjoy. Ribenyi said? When our body moves according to the rhythm of music, our heartbeat and breathing can also be unified in a beautiful rhythm. ?
Running: According to the speed of running, it can be roughly divided into jogging, middle-speed running and fast running. Jogging is equivalent to walking, but not exactly equivalent to walking. China's heart rate is rising slowly. This kind of exercise is mainly used for the elderly, grandparents, people with mobility difficulties and declining health. Running with all one's strength can help them fight against aging and disease. If you can persist for a long time, you will stay young forever.
Medium-speed running, between jogging and fast running, is mainly used for uncles and aunts. After their growing period, their bodies gradually tend to be balanced, no longer? Grow up? This way of running suits them best.
Run fast, very fast, mainly suitable for teenagers. Who are they? Grow up? State, so running can make men's bodies stronger and women's bodies fuller. Not absolutely, of course. Of course, there are many ways, one is specialization, such as 100 meter race; The other is amateur (let's just say that), such as playing football and watching the ball, we should accurately locate, run fast and gallop on the track.
Anaerobic exercise belongs to strength exercise. During the whole exercise, the human body inhales less oxygen than it needs. It is characterized by high exercise intensity, strong explosive force and short duration. Weightlifting, high jump, sprinting and throwing are all anaerobic sports.
Third, be healthy, and second, master the amount of exercise.
As we all know, exercise can keep fit. But people need to master two points when taking part in physical exercise, namely persistence and moderation. Some indicators can be used to control the amount of exercise:
One is the pulse or heart rate immediately after exercise (10 second). After running and ball games, adults should not exceed 140 ~ 150 times/minute, and the elderly should not exceed 120 times/minute.
The second is weight. For example, the maximum weight of weightlifting cannot exceed 70% ~ 80% of the maximum weight I can lift.
The third is time. It is advisable to exercise for 2 ~ 3 hours every day, during which you need to rest many times.
In a word, if you know your basic physical fitness, and exercise properly, timely and moderately according to your own needs, you will have health.
