下面为大家整理一篇优秀的assignment代写范文- Natural science and competitive sports，供大家参考学习，这篇论文讨论了自然科学与竞技体育运动。自然科学与竞技体育运动的发展息息相关，密不可分。随着自然科学的发展与进步，竞技体育迅速发展。然而，随之而来的一系列负面影响，我们需要采取相应的措施减小其不良影响。只有这样，才能充分发挥自然科学在竞技体育运动中的作用，促使其健康快速地发展。

Whether the selection of athletes is appropriate and has great potential plays a decisive role in training excellent competitive sports athletes and improving the level of competitive sports. This is because different competitive sports have different requirements for athletes' physical and psychological characteristics. For example, weightlifting requires that athletes should not be too tall, have good waist flexibility, shoulder joints flexibility and good physical coordination. Different people have different potential for development due to their different physiological characteristics. What is suitable for practicing diving may not be suitable for practicing high jump, and what is suitable for hurdling may not be suitable for 100 meters. Therefore, the selection of athletes is very important. Early teaching and scientific cultivation of potential athletes in accordance with their aptitude can not only avoid the neglect of excellent players, but also save the training cost.

With the development of natural science, genetic technology is gradually mature, and the draft sequence of human genome is basically completed. This technology has been widely used in the selection of athletes in the field of competitive sports. Since biologists have studied some genes from the perspective of genes that can significantly affect human exercise ability, and also from the perspective of molecular level to summarize the human body in the long-term movement of the law. In this way, when selecting athletes, their sports potential can be evaluated according to scientific experience in advance, and whether the selected athletes are suitable for the competitive sports and can reach the competitive level of the competitive sports. For example, genetic diagnostic techniques in the natural sciences can be used to test athletes' athletic ability, coordination, flexibility and physical function. Therefore, the development of natural science can make the selection of athletes more scientific, accurate and specific.

The development of natural science makes more and more high-tech technology applied in sports training. In today's international situation, the development level of competitive sports mainly depends on the level of science and technology. Because today's competitive sports have been developed for many years, the level of competition has basically required athletes to approach or reach the physiological and psychological limit, if you want to have a further breakthrough in the level of competition, only through scientific and technological means to improve the training performance and effect. Therefore, the development of natural science is a necessary condition to improve the performance of competitive sports, mainly through the improvement of sports equipment and high-tech means to assist training. When the advanced achievements of natural science, such as high-sensitivity sensor, computer simulation technology, high-speed camera and other technologies are popularized and applied in sports training, competitive sports will enter a period of rapid development, and the breakthrough of achievement has reached a new stage. Natural science and technology makes the training more scientific, more targeted and more efficient, to accelerate the people understanding of how to improve the competitive sport training rule and control, it can shorten the athletes training period to a certain extent, reduce the cost for the cultivation of the athlete, improve the efficiency of the cultivation of the athlete, is more advantageous to develop a high level of outstanding athletes.

The influence of natural science on competitive sports training is also reflected in the change of athletes' equipment. As competitive sport is a high-level competitive sport, the sports potential of each athlete is not very different, and the equipment and methods of sports training are basically the same because of international exchanges. Therefore, the scientific and technological content of sports equipment will affect the performance of competitive sports to some extent. For example, shark-skin swimsuits can reduce water resistance when swimming. For track and field, the comfort of running shoes and even the number and length of spikes, the distance and distribution of spikes all have a significant impact on competition results. In track and field, the difference between a champion and a runner-up is often a few tenths of a second. On the one hand, the reason for this difference may be the difference in athletic level of athletes, and it may also be the psychological state at the time of the event. Of course, it may also be the technological content of running shoes and clothing. High-tech running shoes can better fit the soles and ankles of athletes. Their reasonable shape design can minimize the air resistance in the competition and maximize the performance of athletes' technical characteristics. According to data reports, "Asian flying man" liu xiang, who wears running shoes specially made for him by NIKE company. By means of scientific and technological means and computer, this paper simulates and analyzes the characteristics of liu xiang's hurdling movement, and combines with the basic data of liu xiang's feet. Liu xiang's running shoes are lighter than other running shoes, and they only have 10 tacks on the bottom, which can effectively reduce the resistance encountered on the track. The distribution of the tacks is also very different from that of running shoes, and is tailored to their habit of landing on the balls of their feet when they cross hurdles. Thus, it can be seen that natural science has a great influence on competitive sports, and the improvement of performance is also obvious.

With more and more application of natural science and technology in competitive sports, the competition of competitive sports also relies on scientific and technological strength. From this point of view, in recent Olympic Games, when athletes are at the same level of competition, which country's athletes choose the better equipment and equipment, the more likely to win.

In competitive sports, along with the development of natural science, more and more technology application in sports competition, such as hd camera, automatic electronic timer, monitor the whole process, equipment, data transmission equipment, the photo finish can effectively reduce the artificial factors on the determination of grades and to ensure the fairness of sports competition. For example, some athletes secretly use stimulants in order to get good results, which is difficult to be detected in the era of low level of natural science development. But now, with the development of doping detection technology, it can be more accurate to find out whether athletes have taken doping, what kind of doping, so as to ensure the fairness of the competition. Still have a more typical example, the accurate decision of champion when 100 meters competition because each contestant's strength is basically equal, the time difference is not long, even only have zero and zero a few seconds, at this moment only rely on the eye of judge or the audience and manual timing will inevitably appear discriminant error. With the development of natural science, there appeared the end camera and automatic electronic timing equipment. In this way, every detail of the end can be recorded clearly, and the finishing position of competitors can be determined accurately, so as to effectively ensure the fairness of the competition.

It is known to all that there are many kinds of competitions in competitive sports, which add color to human's cultural life. Among them, the largest scale of competitive sports is the modern Olympic Games advocated by French educator Pierre DE coubertin, which pursues "higher, faster and stronger". Every Olympic Games attracts the attention of sports lovers all over the world. The development of natural science makes the Olympic Games more and more attractive. For example, there are more and more ways of communication. The original media, such as broadcasting and newspapers, have gradually changed into simultaneous live broadcast on television and network. The change of media enables the audience to participate synchronously in the process of the Olympic Games from lagging behind to knowing the results of the games. Moreover, the development of natural science makes the vehicle more rapid and makes the earth become "smaller and smaller". People can easily and quickly reach the competition site and feel the passion of sports meeting. At the same time, people can interact with each other through the Internet, making the audience feel integrated into the game. These changes brought about by the development of natural science have invisibly expanded the charm and attraction of competitive sports.

Although the development of natural science has greatly promoted competitive sports, it also has some negative effects. Because with the development of human beings, the limit of competitive sports is more and more difficult to be broken, every 0.1 seconds or 0.1 centimeters is very difficult. Conventional training methods have been very difficult to improve the performance of sports, but new training methods and means need to gradually explore, to verify, so as to eventually form a system and mode. This makes the use of scientific and technological means to provide soil for sports performance to break the limit, but if there are too many scientific and technological means in sports competitions, competitive sports will gradually lose the original spirit of competition, and may even become an appendage of science and technology. For example, in order to achieve better results, the development of more difficult to detect stimulants by using science and technology will greatly damage human health and seriously undermine the fairness and justice of competitive sports.

Initially, stimulants appeared in the form of drugs with "pseudo-scientific functions" such as "quick recovery of physical fitness" and "enhancement of physical function", and the hysteresis of detection equipment and means made such drugs confusing to coaches and athletes. The backwardness of detection means inevitably leads to the uncertainty of research on this drug, which makes the drug's harm to athletes very little understood, and thus causes irreversible physical damage caused by excessive abuse of athletes. With the rapid development of natural science, the types and concealment of stimulants are more and stronger, and the existing detection methods are always playing the role of catching up. Doping dose, cycle and other methods to avoid detection also increase the difficulty of detection, all of which make doping the most harmful to athletes.

The aim and spirit of competitive sports is fairness and justice, which is to use sports to educate and develop people, so as to achieve the harmonious development of human and nature. The emergence of stimulants seriously violates this idea and seriously undermines the harmonious development of human beings, which is absolutely prohibited by us.

Nowadays competitive sports are getting closer to the limit of human body. High-intensity sports training increases the probability of sports injury. The founder of modern Olympic movement, French educator Pierre DE coubertin put forward the slogan of modern Olympic is "higher, faster, stronger", and it has been developing in this direction for more than 100 years. Olympism is the core of the Olympic spirit put forward in accordance with the basic principles of the Olympic charter. It has a strong sense of idealism and wants to use competitive sports to change society and develop human beings.

With the development of competitive sports to the present level, more and more people have become the sports at the top of the pyramid, and more and more people have lost the fun of participating because they cannot reach a high level of competition. At the same time, the higher level of competitive sports also increases the probability of sports injury. In order to improve the level of competitive sports, it is necessary to increase the sports load, and the sports load exceeds the physiological and psychological bearing capacity of athletes, and sports diseases and sports injuries will occur. For example, sports hypertension, sports hypoglycemia, sports anemia, sports proteinuria, and even sports sudden death, sports myocardial infarction and other serious consequences. In recent years, there have been many reports on sudden sports death in China. On October 24, 2015, a junior student of nanjing university died suddenly in the physical fitness test of 1000 meters. It can be seen that sports injury is not far away from us. Ren yuheng, a Chinese scholar, conducted a survey on 6,810 outstanding athletes, and 59.37% of them suffered sports injuries. Thus, it can be seen that athletic injury of competitive athletes is a common phenomenon with high incidence and diversity, which to some extent affects human health and reduces people's enthusiasm to participate in competitive sports.

Natural science is a double-edged sword, both positive and negative. Therefore, while using natural science to promote the healthy development of competitive sports, we should also formulate a series of countermeasures to reduce its negative impact.

Strengthen the propaganda of competitive sports spirit, so that athletes, coaches and managers in competitive sports can deeply understand the connotation of competitive sports. Only by improving the quality of these personnel, can they set up the correct sports concept, so as to play a positive role in the source, effectively put an end to the negative overuse of natural science in competitive sports.

A professional scientific research team, pay attention to the cultivation of scientific research personnel, increase investment in scientific research funds, construction of high level scientific research laboratory, the development of more efficient, more intelligent detection method, lower cost, improve the existing doping detection techniques and methods, to increase the use of stimulants, coaches and athletes to reduce the damage to the whole of competitive sports and athletes doping.

We should strengthen international cooperation, improve China's relevant laws and regulations in accordance with the legal system of mainstream international countries on penalties for violations of competitive sports, and increase penalties for coaches, referees, athletes and staff members who violate the spirit of competitive sports. For all kinds of behaviors that violate the spirit of competition in competitive sports, once found, we should find out the facts and define the responsible person, and deal with them in strict accordance with relevant laws and regulations.

Natural science is closely related to the development of competitive sports. With the development and progress of natural science, competitive sports develop rapidly. However, we should also face up to a series of negative effects and take measures to reduce their negative effects. Only in this way can we give full play to the role of natural science in competitive sports and promote its healthy and rapid development.
