The equipment we developed to meet the above conditions has many difficulties, such as "running", which is the most important quality of the human body; From the "runway" to the "treadmill" should be an improvement, but we can't bring the treadmill to the campus, let alone return to the "runway" and let the students run endlessly; There are all other qualities and abilities, too. Only with a new way of thinking can there be innovation and breakthrough. If you want to develop scientific and practical instruments, you can't stay on the surface appearance and posture of sports, but you should have a deeper understanding of sports, understand the internal factors and physiological mechanism of sports, and understand its causal relationship in theory, so as to make a breakthrough in research and development.

First, the deep analysis of the basic function of sports

From the perspective of sports biomechanics and anatomy, the basic functions and qualities of the human body are different from the above-mentioned "perspective" and should be divided into strength, dexterity, endurance, nerves and psychology; Because running, jumping and throwing, the three elements that cover people's ability, are closely related to people's muscle strength; The dexterity of human body is closely related to the relaxation flexibility of bones and joints, the quality of ligaments around joints and the speed of nerve reflex. The tolerance of human body is related to the ratio of red and white muscle fibers and people's psychological quality. In other words, the development of running, jumping and throwing ability can be realized by improving muscle strength, but this is not the "all" to improve these three abilities. In fact, strength exercises have two completely different concepts: "isometric exercise" and "stretching exercise" (or "extreme exercise"). Workers work all day and do a lot of strength exercises, but they have not become sports "superman" because they are not. The number of human muscle fibers is a lifelong exercise of isotonic contraction, and it is impossible to make the length of muscle fibers change greatly, only the thickness of muscle fibers changes; Just like a long but not very thick rubber band, its elasticity is definitely better than a short and thick rubber band. In other words, the key to a person's ability mainly depends on the length of his muscle fiber. Here, you can also give a more practical example: the fitness equipment we developed, to put it bluntly, their scientific nature remains to be discussed. Their common fault is that they don't consider the "essence" of the effect of equipment on human physiological mechanism. In fact, they are helpful to the training of "bodybuilding", cycling and rowing, but they have no effect or even reaction to other more sports. Because, through the exercise of fitness equipment, the muscles are strong and the strength is great, but in fact, the improvement of athletic ability is very limited, because the strength through it is mainly the absolute strength of the individual, and the relative strength of the individual is the main performance of athletic ability (this involves deeper academic discussion and cannot be discussed more); From the point of view of physiology, economy and practicality, fitness equipment, including the existing "path", is not suitable for schools, which is the problem. Then the equipment we develop must be different from fitness equipment and "path". It should be a principle that athletes are not allowed to do "muscle isotonic" exercises on equipment and that children are not allowed to do "hard work" that they hate. The result is not effective, but affects their physical development and mental health.

Second, the analysis of physiological characteristics

There are three periods in a person's life, namely: infancy (before 8 years old), adolescence (8- 18 years old) and adulthood (18 years old). In addition, there are two physiological periods that determine a person's physical structure, body proportion and physical condition. The first period is from mother's five months to half a year after birth, and the second period is adolescence. The influence of the first phase on external conditions is limited, while the external factors of the second phase can be completely influenced; People also have a rapid growth period, with females aged 8- 16 and males aged 10- 18. Among them, 15 years old is a rapid growth period, and 16 years old reaches a peak, then decreases year by year until the development is basically completed at the age of 22. In this way, we can see that students in primary schools, middle schools and universities are all in adolescence, and their healthy growth in this period is related to their life. Numerous facts have proved that scientific physical exercise plays an irreplaceable role in the developing human body's physique, psychology and intelligence, which is also the reason why the party's educational policy puts forward "health first".

In the pre-adolescent children and pre-adolescent stage, the development speed of human bones is faster than that of muscles, especially the strength of small muscle groups is very weak. Therefore, children and adolescents have poor coordination, tolerance and absolute muscle strength. In this period, physical exercise has a very positive effect on their growth and development, because physical exercise can promote metabolism and is of great significance to the better development of the body. During this period, the nervous system is in the "generalization period". They are active, excited and tired, and the excitement shifts quickly but it is difficult to concentrate for a long time. Teenagers in the late adolescence tend to be mature, and their body and mind are at a critical turning point. They have their own opinions, but they are also prone to "autism", which is called "passive resistance period" physiologically. Scientific physical exercise can well mobilize their nervous system, concentrate their excitement, and play a very positive role in developing their intelligence, improving their psychological and self-control ability and cultivating their social consciousness.

We have mastered the physiological characteristics of children, teenagers and young people in different periods, and our instruments have a basis for targeted development and design.

Thirdly, the analysis of movement mechanism.

The exercise carried out by the human body is basically embodied in two ways, one is aerobic exercise and the other is anaerobic exercise. What is aerobic exercise? Simply put, "aerobic metabolic exercise" is a steady and continuous exercise, so that the oxygen demand of muscles does not exceed the available supply of heart and blood. The metabolism and energy supply of energy substances in muscle are carried out under aerobic conditions, with thorough oxidation and sufficient energy supply. This method is not only laborious, but also not too laborious. It can ensure that fat and sugar substances are fully decomposed under aerobic conditions to generate heat and energy, and fat is fully burned and thoroughly decomposed. It is the most effective way to strengthen muscles and remove subcutaneous fat. Aerobic metabolic exercise is a way to keep the balance of oxygen supply and demand in the process of exercise. On the contrary, anaerobic exercise; What are the characteristics and advantages of aerobic exercise? Many people know that aerobic exercise is good for health, but most people can't say clearly what aerobic exercise is. Some even intuitively think that aerobic exercise is to exercise in an oxygen-rich environment. In fact, whether it is "aerobic exercise" is measured by heart rate. During physical exercise, when the heart rate reaches 70%-75% of the maximum heart rate, it can be considered as aerobic exercise, and self-feeling can also be used to measure one's state during exercise. Among the five levels of self-feeling, it is considered as "a little tired" and "quite tired".

What are the benefits of aerobic exercise? Expert diagnosis: 1, which can obviously improve the functions of the brain and cardiopulmonary system, stimulate and improve various physiological functions of the human body, promote the growth and development of the human body, and help to slow down the aging and decline of physiological functions of muscles, hearts and other organs. 2, it can reduce the occurrence of cardiovascular and cerebrovascular diseases and effectively prevent arteriosclerosis. 3, it can prevent and treat sugar diseases and help to lose weight. Here we should look at the harm of anaerobic exercise in turn. Anaerobic exercise due to lack of oxygen, substances in the body can not be completely decomposed into carbon dioxide and water during metabolism, but produce many acids harmful to the human body, such as ethanol, acetic acid and lactic acid-people will feel leg acid when going upstairs or walking, which is caused by too much lactic acid in the body. The PH value of healthy body fluids is weakly alkaline, which is 7.4. A large amount of ethanol, acetic acid and lactic acid will make body fluids sour, thus causing acidosis in the body and even death in severe cases. Anaerobic exercise not only harms the heart, but also leads to systemic metabolic failure. One of the causes of sudden death during strenuous exercise is the damage to the body caused by anaerobic exercise.

Introduction of the inventor of sunshine sports equipment:

Niu Guangsheng,1born in Beijing on August 4th, 943, started amateur sports training at the age of 7. 16 was sent to Beijing Institute of Physical Education, graduated at the age of 23, and left Beijing Institute of Physical Education at the age of 25. He was a physical education teacher in primary and secondary schools for half a year, and the chairman of trade union No.9 of Metallurgical Steel Company for three years. 1938. 1987 foreign aid expert, 9 1 returned to China as the director of Henan Scientific Research and Training Center (main achievements: trained 19 athletes, disciples won the national championship six times, and the China junior track and field team composed of all the players I trained went to Italy to participate in the world junior track and field championship, 194 won the team championship. In 9 1 year, he was awarded the title of the first batch of national senior coaches. My hobbies: oil painting, calligraphy, carpentry, musical instruments, sewing, acupuncture, adventure travel. Oil painting won the first prize in the 2005 Henan Painting and Calligraphy Competition. Acupuncture needs blowing. After three years as a foreign aid, one year as a sports expert and two years as an acupuncture expert in traditional Chinese medicine, he was killed in the Jordanian palace. Retired in 2003, spent more than two years riding a motorcycle "across China", with a total journey of nearly 50,000 kilometers, east to the seaside, west to Tianchi in Tianshan Mountain, south to Sanya and north to Heihe River.
