Life is movement
Animals and humans in the process of life, always in constant motion. From ape to man, after about two or three hundred years long development process changes. Human organism, hatched from a single fertilized cell differentiation as nature's most advanced, most complex organism, is the result of the cells stop moving moving. Visible, no Dodo no life.
When it comes to "sport", it is inseparable from the "muscle." Roman statue from the athletics family, to the modern arena strong body, humans engaged in a variety of physical and sports activities, and both are the result (skeletal muscle) muscle movement. There is also a smooth motion, such as gastrointestinal motility, etc., but also maintain the balance of organic metabolism in vivo environment and the need for exercise, but also one of the sources of life activities.
From the microscopic world view, constitute the basic unit of the human body - cells are always in motion. White blood cells to destroy bacteria in motion; red blood cells transport oxygen and carbon dioxide in motion; marrow cavity osteoblasts continue to disrupt and absorb bone, the bone cavity to expand the campaign; osteoblasts continue to manufacture bone periosteum, the bone bold in sports; epiphyseal cartilage ends of long bones proliferation and bone ossification longer also sports; All cells are self-renewing and exercise ...... modern science has proven that the human body is composed of nearly sixty kinds of elements, in which the human body an essential element of life activities have twenty or five. In more than twenty kinds of elements, most are hydrogen, oxygen, carbon, nitrogen four, together accounting for more than 99% of total body atoms.
It is because of these elements constitute a variety of living matter in our body. In the matter of human life activities, the most important are the two high-molecular substances: proteins and nucleic acids. Proteins are nitrogen-containing organic compounds - amino acids, it is the most important component of all cells, is cell movement, the basic material change of life constitutes the most important material. Nucleic acids DNA and RNA are divided into two categories, the former is to bring a fertilized egg from parental genes, is the material basis of heredity, so humans have children, parents often like this genetic phenomenon. However, under certain conditions, DNA in the number, arrangement, and the upper sequence is variable, this variation of the image caused by both parents and children, not identical with the development, there are variations. Synthesized RNA and proteins. From biopolymers, especially from the structure and function of proteins and nucleic acids to understand the phenomenon of human life, so that we change on human development, especially with the further understanding of the basic properties of the body, but also for how physical exercise, effective development of human and peoples to enhance physical fitness, providing a basis for the biological sciences.
In good health on the basis of the life can be extended. The study found that exercise every day mice than closed immobile similar mice, long life 25%. Rabbits can live 15 years on average, rabbits only live 4-5 years. Sheep dog can live for 27 years, family dog only live for 13 years. Elephants in the wild can live to be 200 years old, grew up to capture the feeding of elephants live less than 100 years old. Long wildlife breeding animal life than the main reasons is that the reason they are often kept frequent movement. Post office workers, field staff life than to sit back office personnel office life much longer.
In summary, physical exercise can enhance immunity; prolong life; promote health; also promote human evolution. However, physical activity certainly can not do without a perfect venue to promote a perfect venue certainly inseparable from the current market constitutes the most popular artificial turf, the company is selling artificial turf are welcome.
