What are the benefits of physical exercise
Promote blood circulation, prevention of vascular disease
Exercise makes breathing faster, heart rate enhancement, increase the oxygen content of the blood, promote blood circulation, can soften the arterial blood vessels, make blood vessels elastic, prevention of arteriosclerosis and other vascular diseases.
Promote the body's metabolism, also has a weight loss
Exercise can accelerate the body's metabolism, remove excess body fat, shape the perfect body, want to lose weight friends, you can do more exercise.
Exercise can also be laxative, eliminating toxins from the body.
Enhancement of physical fitness
After exercise to promote blood circulation, oxygen can be fully supplied to all parts of the body, thus enhancing the function of various organs. People who exercise regularly seldom catch colds, because exercise enhances the body's function and is able to resist cold viruses well.
Improvement of facial luster
Regular exercise can make the skin of the face become taut, elastic and rosy. The next door neighbor old lady is often to the square square dance, already 60 years old, face skin is still very taut, not like 60 years old people.
Enhancement of temperament
Regular exercise will have a very mental outlook, the whole person's body and state are very good. For example, dancing people, people know at a glance that she is a dancer. The main thing is that the temperament is there.
Favorable to physical and mental pleasure
Sports not only make the body healthy, but also make people become sunny and positive. When faced with setbacks, there will be a good mind to face. So it is very important to exercise more and build a good mindset.
Long height
Exercise can promote the growth of children's height, some worried about the height of children's parents, in the exercise, may wish to bring their own small children together.
What are the benefits of exercise
First, improve the shape
The most basic role of exercise is to change the shape of the body, through fitness can make any part of the body (as long as there are parts of the muscular tissues) to increase or decrease and effectively change its shape, to achieve the effect of a beautiful body, and this process is controllable, which is often referred to as the role of weight loss and shape.
Second, the movement is conducive to the health of the whole body from the inside out
In order to study the relationship between exercise and health, Soviet scientists have done the following interesting experiment.
A group of men aged 20 to 30 years old confirmed by the examination of the body completely healthy as an experimental group, the provisions of the 20 days and nights have been lying down and not allowed to sit up, stand up and do gymnastics. Another batch of the same conditions as the control group, according to the above provisions to accept the experiment, the difference is that a day and night to allow the control group to maintain the basis of lying down, can be in the specialized equipment on the exercise four times. After three or five days, all the people in the experimental group reacted with sore back muscles, loss of appetite and constipation. After twenty days and nights had passed, when they stood up from their beds, they immediately felt dizzy and lightheaded, their muscles were extremely weakened, their pulses abnormally quickened and sharply slowed down, their arterial pressure was dangerously high, and their heart function decreased by 70%. The tissues of the body were severely deprived of oxygen, and even standing and walking slowly caused muscle aches and pains. This condition persisted until 2-4 days after the end of the experiment. The control group, on the other hand, basically maintained the level of work capacity. Too little activity can cause changes in the central nervous and endocrine systems, which cause emotional instability, metabolic disorders, muscular atrophy, changes in the composition of bone tissue, acute malignization of the cardiovascular system, gastrointestinal dysfunction, and renal dysfunction. It can be seen that physical exercise is good for health.
Third, exercise can extend life
On the basis of good health, life can be extended. It was found that the daily movement of rats than shut down immobile similar rats, life expectancy of 25%. Wild rabbits can live an average of 15 years, domestic rabbits can only live 4-5 years. Sheepdogs can live 27 years, while domestic dogs live only 13 years. Elephants can live to be 200 years old in the wild, and elephants captured and fed from childhood live to be less than 100 years old at most. The main reason why wild animals live longer than domesticated animals is that they are kept in constant and frequent motion. Post office workers, field workers live longer than those who sit in the office.
Fourth, exercise can promote the growth of bones, is conducive to taller
The growth of the organism mainly refers to the reproduction of cells and intercellular matrix caused by the increase in the form of changes; development includes the organism of the organism of the system in the form of structural and functional changes.
Bone growth determines height. It is very important to promote the healthy growth and development of bones in primary and secondary school students through physical exercise.
The growth of height is mainly due to the continuous lengthening of the long bones of the limbs. In the limbs of the long bones of the bone and epiphysis (long bones at both ends of the expansion of the part), children and adolescents have epiphyseal cartilage, this layer of cartilage continues to become hard bone, and constantly generate new cartilage. In this way, the bone will continue to lengthen, this growth process in children and adolescents is very exuberant, generally to the age of 20 to 25 years old epiphyseal cartilage is completely ossified into an epiphysis, then the bone will no longer lengthen. In the bone growth period, reasonable physical exercise can promote blood circulation, increase the blood supply to the bone, so that is in the exuberant bone building period of bone tissue to obtain more raw materials, thus accelerating the bone building process; in the process of participating in various sports activities, so that the bones are subjected to a variety of stimuli, the growth of the bones is very beneficial. Research has proved that regular participation in physical exercise 10-14 years old students than the same age of students who do not exercise regularly height 4-8 centimeters.
In addition to helping bone growth, physical exercise also helps to make the bone harder, and play a better role in supporting and protecting the human body. Generally speaking, the bone's pressure-resistant ability than granite 25 times larger than a brick 30 times larger than a person weighing 70 ~ 80 kilograms standing tibia (calf bone) can withstand 1.5 ~ 3 tons of heavy pressure without fracture. In physical exercise, due to muscle pulling and gravity, the muscle attached to the bone on the bone protrusion site increases. Exercise on the mechanical stimulation of the bone increases, so that the cellular metabolism of the bone is more vigorous, coupled with exercise to accelerate blood circulation, faster and more supply of nutrients, and so make the bone thickening, the outer layer of the bone thicker dense. The announcement of bone cancellous material is compatible with the muscle tension and the action of human gravity, and the arrangement of bone trabeculae is more reasonable. Over time, the bone's sturdiness, resistance to fracture and twisting properties are subsequently improved. Physical exercise in the outdoors, the body is irradiated by sunlight, which contributes to the generation of vitamin D in the body and the absorption of calcium and phosphorus, so that the bone becomes harder and can withstand greater pressure.
V. Exercise to enhance memory and analyze the ability to synthesize
Memory ability depends on the structure and quality of the brain. Brain tissue is very sensitive to the supply of oxygen, it consumes 1/4 of the total amount of oxygen in the human body. if you want to make the memory strong, first of all, to ensure that the brain gets enough oxygen. It has already been clarified that physical exercise improves the function of the respiratory and cardiovascular systems, thus providing the necessary energy and oxygen for the development of the brain. Human memory and intelligence is also related to whether the contact between the central nervous system and peripheral nervous system of the brain is complete and numerous. Often participate in physical exercise, visual, auditory and other sensory acuity, the nervous system's ability to analyze and synthesize the increase in the speed of nerve fiber conduction, increased flexibility, the human brain's memory reserves of information has also been improved.
Six, eliminate brain fatigue, improve learning efficiency
Movement is a positive way to rest, because when the movement, the nerve center related to the movement is excited, and the center related to cultural learning into the state of inhibition. This inhibition is deeper as the excitation of the motor center is strengthened, thus giving the nerve centers related to cultural learning a good rest and a protective effect. Physical exercise after learning and can increase the supply of oxygen and nutrients, is also conducive to improving the function of the brain.
Some businessmen also see the business opportunities, with a variety of means to make a lot of money, but the results of many people tend to be exhausting but in vain, because those are the way to treat the symptoms of the disease, not from the root to improve the human body. In fact, the key to health and beauty is in our hands - that is fitness. Fitness can bring us the benefits:
Seven, exercise to enhance cardiorespiratory function
For example, only on the heart, the regular quiet heart output per beat for 60 to 80 milliliters, athletes up to 100 milliliters or more, so the athletes are quiet when the heart rate of the regular slow and powerful (athletes are quiet when the heart rate of about 50 times a minute, the regular people for about 70 to 80 times). The heart rate of an athlete at rest is about 50 beats per minute. Reflecting the higher level of heart function appears to save the superior heat. Japan's famous marathon athlete Segou Rihiko, was three times reigning international marathon champion, scientists did a comprehensive examination of him, found that the ratio of his heart volume and body weight, topped all Japanese athletes, and the thickness of the heart wall and the shape of the heart are better than other athletes. His maximum heart rate amounted to about 240 beats per minute, whereas regular people could only reach about 180. It is as if Sekou had a high-powered water pump inside his lightweight body to support physical exercise with powerful horsepower. This reflects the advantage of efficient heart function when exercising intensely, which is the result of years of persistent exercise in sports life.
