Popular science knowledge-the origin and development of modern biomechanics
Modern biomechanics originated in the late 1961s, and the development of biomechanics and sports biomechanics entered a period of formation and development. During this period, experts actively studied the biomechanical characteristics of human and animal movements. The scientific research of the following scholars is widely known: Biomechanics by Alexander in 1971; In 1974, Wu Ke Brodovich made a mathematical simulation of animal movement, which promoted the development of robot manufacturing technology. In 1968, Hillier Bohlander founded the theory that animals move with uniform footwork. In 1968, Suhonov established the general system of terrestrial vertebrate movement; Hatton's research on the regulation mechanism of human support sports system; Miller's research on biomechanics of human motion. The first international symposium on biomechanics was held in 1967. In 1973, the International Society of Biomechanics (ISB) was formally established, which marked the formal establishment of biomechanics. During this period, sports training was formed as an independent discipline in the Soviet Union, but before that, it only developed in the category of physical education. The following textbooks became the first works to elaborate the knowledge system of sports training: Modern System of Sports Training by Ozolin of the Soviet Union (1971), Training Science edited by Harriet of Germany (1971) and Theory and Method of Sports Training by U Lidovski of Poland. This has promoted the development of sports biomechanics in the new scientific direction of sports training.
the development of popular science knowledge
with the continuous expansion of the research scope of sports training, the research on biomechanics from different angles in the technical analysis of athletes' completing competitions has been actively developed. At present, most of the main institutions studying sports biomechanics are in eastern European countries, such as Poland, Russia (mainly in Moscow, St. Petersburg, Volgograd, Krasnodar, Novosibirsk and other cities) and Ukraine (Kiev National Sports University and Kharkov National Academy of Sports Sciences). The practical significance of modern sports biomechanics research is determined by the following two reasons: on the one hand, the social significance of sports is constantly improving and the number of sports events is constantly increasing, which determines the necessity and prospect of sports biomechanics research; On the other hand, with the rapid development of science and technology, many new scientific research methods have emerged, which makes it possible to comprehensively study the athletes' skills in completing competitions, and consequently can improve their training and competition results.
There are clearly several directions in the development of modern biomechanics, namely, engineering biomechanics, medical biomechanics and educational biomechanics (Donskoi, 1997). Engineering biomechanics and medical biomechanics have been well studied theoretically, and there are well-known and used instruments and equipment, which determines that their research is based on a relatively high level of scientific methods, but there is another situation in the research of educational biomechanics, which is mainly used to solve teaching tasks.
Educational biomechanics is a relatively new branch of biomechanics research, which is still in the stage of accumulation and understanding of basic materials and is forming its own theoretical theory. At present, an important task of educational biomechanics is to create a theory based on the conceptual system that explains and predicts the main development direction of the studied phenomenon.
The expansion of the research scope of biomechanics on physical education and sports problems and the further development of physical education and sports theory have promoted the formation of a relatively new research direction in educational biomechanics-evolutionary biomechanics. The main task of evolutionary biomechanics is to reveal the law of action evolution by studying the law of human natural development, which is indeed an important task, because if we can't understand the law of human motor function changing with age, then it is impossible to make a training plan correctly.
The results of scientific research conducted by Balisevich, Professor Sudura and Academician Yang Jintian indicate that: (1) there is imbalance in the development of human motor function components and structures (used to ensure the form and functional mechanism) during individual development; (2) The development of human movements in individual development is multi-level and rhythmic; (3) The performance of human movements in individual development is highly personalized; (4) The absolute result of the development of human motor function depends on the characteristics and intensity of physical activity.
