Opportunities and challenges of competitive sports in nano Era

: Nanotechnology is a technology with high requirements of science and technology and involves many comprehensive d isciplines. With the continuous d evelopment of scien ce and technology, nanotechnology has penetr ated into all aspects of our lives. Now nano mate rials, nano pu mps, Nano Electronics and nano technology hav e been applied in the competitive fi eld of Chin a. I t is th ese nanotechnologies that have made great progress in the field of sports competition in China. Looking to the future, we have to pay attention to the physical and mental health of athletes in the era of sports competition. At the same time, we should be good at using nanotechnology to pr omote the healthy and harmonious development of sports competition in China.


Nano concept and characteristics
As early as the late 1950s, the famous American physicists once predicted that if we ca n control and process atoms, then our science will tak e a big step forward and realize great changes in science. In t he 1980s, the emergence of nanotechnology, as i f to verify the physicist's prediction, nanotechnology has a profound impact on the world. After decades of development, na notechnology has not onl y been a pplied i n t he fi eld of physics, but al so pe netrated into all asp ects of life an d in to various compreh ensive disciplines. Nanotechnology has also had a huge impact on our co mpetitive spo rts. In th e face of t his vigorous development of ad vanced s cience a nd t echnology, t he field of spo rts co mpetition has obtained great opportunities, but also faces challenges. How t o use nanotechnology in sports competition? What changes will nanotechnology b ring to sp orts competition? Will nanotechnology h ave a n egative impact on lo cal taboo? However, i n t he l ong run, t he a dvantages o f nanotechnology outweigh the disadvantages. Many sports professionals and sci entific and t echnological wo rkers still reco mmend t he ap plication of nanotechnology in sports co mpetition, and as an impo rtant st rategy, it has attracted the majority of workers' attention.
In esse nce, nanometer is a measure of length. Nanometers can calculate very small atomic diameters. A nanometer can be regarded as the diameter length of ten H atoms con nected. C ompared with t he familiar u nit of meter length, o ne b illionth o f a meter is eq ual to one nanometer. It is conceivable that this unit of measurement can no t be observed with t he nak ed ey e, it exists i n t he micro world. Nanotechnology is a kind of technology that uses the knowledge of various disciplines and the nature of interdisciplinary to manipulate the micro so as to obtain the mat erials or materials we nee d. Na notechnology mainly studies three directions, including nano materials, nano scale and n ano devices. There will b e a scien tific progress in each era, which will lead to changes in this era. The nano era is mainly based on nanotechnology, and the use o f e xisting i nformation technology has a pr ofound impact on people's life and learning style. However, from an objective point of view, our grasp of nanotechnology has not reached a mature level. Sometimes, the nano era we expect has not really c ome. The c haracteristics of nanotechnology are high precision, high depth and strong universality. If we h ope that technology can p roduce technological changes in our s ocial life a nd become the industrial revolution of th e 21 st cen tury, we still h ave a way to go.

Nanotechnology influences sports competition
Nanotechnology, as its name implies, has swept the world with a rapid speed, and competitive sports are also deeply influenced by nanotechnology. Nowadays, athletics is no longer a single player for athletes. It is no longer the same as in th e p ast. Athletes on ly rely on h ard train ing to achieve success. Now the e ra requires multi-disciplinary cooperation in sports training. Nanotechnology can deeply tap the potential of athletes, produce more efficient sports equipment, a nd produce m ore p rofessional su pervision and man agement vessels. Nan otechnology can pro mote the vigorous development of sports, and it has b ecome a tacit fact that the light of science and technology can bring gold medals to China's sports. Nano system contains a lot of physical p roperties, s uch as i ts ph otothermal bat tery, which is obviously different from other ordinary materials. These goo d ef fects will provid e better sports cond itions for sp orts co mpetition. The comb ination of nanotechnology and sports co mpetition prov ides a great opportunity for th e rapid d evelopment of spor ts competition.
First of all, in China's sports, many specific equipment and e quipment need t o be achi eved t hrough nanotechnology. Athletes can use these innovative sports equipment to train their physical fitness and the subjects they are good at, and help athletes get better results in the next competition. Behind the gold medal winning of each athlete, there i s actually the shadow of sports equipment innovation, such as the establishment of standard circular ring, and the construction of high-altitude platform, which create good sports conditions for th e athletes, which can make th e at hletes p ractice mo re sk illfully an d meet th e standards. In the era of nanotechnology, in order to help athletes bet ter t rain, people ha ve al so i nvented t he mysterious sh ark s kin sw imsuit, th e g lass fib er rod, th e shocking high hit rate arrow and so on. Although athletes' own e fforts are the most im portant reaso n to win the championship. But it is also because of the emergence of these equipme nt, s o that athletes ha ve the coura ge to overcome difficulties in the world arena, constantly write world hi storical reco rds, t o break, t o i nnovate. Athletes holding suitable nano sports equipment, not only reflects their o wn p ersonality, but also mak es themselves more involved in t he co mpetition, wh ich is co nducive to t he athletes to create better results.
Moreover, scien tific sp orts can guarantee the normal development of m odern s ports t raining. Therefore, modern e quipment a nd mo dern c ommunication equipment ha ve become t he mai nstream o f modern scientific training. If we apply nanotechnology to today's computer t echnology, we ca n increase t he ef ficiency of computers by several 100000 times, and make computers have more e fficient t ransmission frequency. In a ddition, nanotechnology can stor e more inf ormation. A nano processing disc ca n st ore ab out 300, 0 00 C hinese characters, a nd i ts st orage c apacity ca n be hu ndreds of times more t han that of ordinary optical disks . For example, Beijin g library has a co llection of 20 million books. I f we print t he c ontents of t hese books on nano laser disks, the storage capacity of nano optical disks is less than 1 / 30, wh ich shows that the storage capacity of nano optical di sks i s very large. Therefore, i n s ports competition, we can make nano products, whether it is to add th e ex isting sp orts books and materials, train ing methods, etc. to the nano CD-ROM, or the application of nanotechnology to electro nic p roducts, will g reatly improve the efficiency of sports competition. At the same time, we ca n al so ap ply na notechnology t o t he management eq uipment of sp orts comp etition, such as supervision equipment, so that I can use the equipment to correct the wrong posture of athletes and innovate the movements of athletes, so that athletes can better grasp the details of each action , at t he same time, it can help t he referee to better supervise whether the athletes violate the rules. Su ch nanotechnology w ill bring higher work efficiency for sports competition.
Finally, we pay at tention t o t he development of nanotechnology a nd promote t he de velopment of nanobiology. Nanotechnology allows us to have a deeper understanding of th e pr ecise stru cture an d functional properties of small mo lecules at the na noscale. Once a famous foreign sports medicine master once put forward such a view: t here is 60 % probability th at hu man body function is determin ed by h eredity, while o nly 40% probability is affected by other factors. Modern medicine gave birth to the Manhattan Project, which can test human genes to determine whet her a person has great exercise potential from a genetic point of view. We can determine the position of the athlete's maximum potential and limit by measurement. Na notechnology makes i t possi ble f or people to study human bod y fu nctions at th e mo lecular level. Through sci entific di agnosis a nd e fficient ge ne testing, t he co untry ca n sel ect a group o f excellent a nd potential athletes. At the same time, n anotechnology can be used in the field of pharmacology. Nanotechnology has played an important role in controlling the release system, improving the utilization of organisms, and improving the targeting of drugs. After entering the human body, these drugs ca n act ively repair t he dama ged t issue cel ls o f human b eings, and will no t leav e any garbage in th e human body. The emergence of these drugs can provide a good material basis for athletes. If the athletes are injured on the field or have accidents during training, they can be used for related treatment.

Severe challenges of competitive sports in the nano Era
Since entering the 21st century, nanotechnology has been developing unprecedentedly, especially in this era of rapid development of science and technology, nanotechnology can be widely used in various occasions, therefore, we can also think that the current era can also be called the nano era. Nowadays, with the development and application of nanotechnology, i t has bee n p romoted a nd applied i n sports competitio n, an d t he use of nanotechnology can make t he spo rts i ndustry flou rish. However, it is undeniable t hat na notechnology i s al so a d ouble-edged sword. In the development of sports, if there is a good side, there will inevitably be a bad side. In the lessons of history, we can know that science and technology can make the sports industry develop better, but it will also bring serious consequences. With t he help of sci ence a nd t echnology, sports competition is more excellent, but the physical and mental health of athletes is a ffected, which is against the spirit o f t he O lympic movement. Therefore, we s hould make goo d use of scien ce and tech nology, and let nanotechnology be used pr operly. While bringing development to the sports industry, we should also follow the spirit of spo rts competition. We should consider this problem from the future sustainable development, how to use nanotechnology, wh at i mpact will b e brought to t he sports industry after using nanotechnology, both good and bad as pects s hould be c onsidered. Only in t his way can nanotechnology and sports industry progress together and provide reliable theory for the development of the industry.

3.1.It may damage the physical and mental health of athletes
3. With the development of the times, nanotechnology has been wi dely use d in vari ous fields, sports have also adopted th e tech nology. It is tru e t hat tech nology has brought conv enience to sports, b ut i n th is p rocess, t he contact between at hletes' s kin a nd na no part icles i s inevitable. Although skin is a barrier for human beings to block s ubstances, i t has no resi stance t o so me micro nanoparticles. Nanoparticles may penetrate into the body and d iffuse i n th e body when co ntacting with th e sk in. Sometimes the y ev en en ter th e organelles s uch as mitochondria, en doplasmic mem brane an d other organelles t hrough t he ga p of bi omembrane t o p roduce chemical reactions with lar ge b iomolecules, resu lting i n changes in th e co nventional stere ostructure of macromolecules or b iofilms, resu lting in th e lo ss of enzyme and hormone activities in the body, and even the change of genetic materials, whic h can a ccelerate the aging of tumors. There are al so some problems, such as penetrating b lood t estis bar rier, a ffecting s perm production, reducing sperm motility, hindering embryonic tissue differentiation, resulting in fetal malformation and congenital diseases.

3.2.It may cause imbalance in sports development
When the original sports do not exist with high technology, and s ports ar e not er oded by ne w t echnology, people pursue a higher, faster and stronger level. In the process of sports competition, athletes display their strong physique, challenge th e limits o f their bo dies, an d show th e superiority of human beings in distinguishing animals in physiology. The comp etition is fair, fair and open. With the development of s ports a nd s ocial ec onomy, pe ople's values ha ve c hanged a nd deviated from t he ri ght t rack. The temptation of money, reputation and status brought by competition leads to the deviation of simple sports from the route and cannot be returned. As one of human civilization, mo dern hi gh-tech has become the main means t o i mprove s ports performance. I n order t o wi n, gain fa me a nd f ortune. In t his ki nd o f high-tech s ports competition, t he Olympic prin ciple of j ustice h as been destroyed, and the dominant position of athletes has been weakened. It's not the strength of athle tes, but the advantages o f mo dern t echnology c ompared with ol d technology. C ompetitive spo rts is originally a k ind of innate ab ility, but now th e significance of th e orig inal training l evel comparison ha s bee n partially l ost, an d competitive sports tend to one strange circle after another. Perhaps th e b irth of nanotechnology is not a good th ing for sports.
The de velopment and d issemination of new technology need st rong econ omic str ength t o promote. Even with advan ced scien ce and techno logy, it is very difficult for a co untry with in sufficient co mprehensive national st rength t o popularize i t. Although t he international community has been advocating the sharing of scien ce and techn ology, in reality , there h as been regional i nequality in th e development of scien ce and technology. In addition, as an emer ging core technology, nanotechnology needs high investment, high technology and h igh precision, w hich many developing countries cannot ach ieve. Dev eloped countries rely o n n ational strength, steady d evelopment, mono poly of sp ecific projects, t hus promoting eco nomic de velopment, while developing countries can only sigh, lack of financial and technical support, reduce their interest in developing their own sports development, a vicious circle. External factors are also th e i mportant factors t hat lead to th e in ternal failure to obtain fair competition in competitive sports.
With t he development o f sports, a l ot o f high-tech products have been developed. F or e xample, t he emergence of stimu lants. With th e co ntinuous development of modern high-tech, the variety of doping is shocking. B ecause of i ts s mall st ructure, nano mat erials and nano motors are more likely to be used in doping. The development of n ano dr ugs may increase th e types of prohibited drugs, t he detection i s di fficult, d oping detection should be strengthened!

Conclusion
Competitive sp orts is th e i ntangible cu lture inh erited by human history, which enriches the spiritual life of human beings. It i s a h uge weal th and w orth i nheriting. The intervention of scien ce and t echnology can pro mote t he development of comp etitive spo rts, but th e future of competitive sp orts can no t comp letely rely on th e development of science and technology. The combination of science a nd tec hnology and s ports af fects the real strength of athletes and the sense organs of the audience. The n ano er a is u ndoubtedly th e spr ingboard fo r t he development of competitive sports. However, in the wave of nanotechnology, we should also realize that competitive sports are faci ng se vere c hallenges i n t he era of nano technology, and t he inv estigation of ch eating in spo rts competition will in crease t he d ifficulty. The national sports de partment sh ould consi der t he i mpact of nanotechnology dev elopment, ex plore its f uture development d irection, estab lish n anotechnology development plan, strengthen social education as soon as possible, an d explain t he punishment f or v iolations. On the basis of the competition in the field of nanotechnology, rational layout should be made. Facing the challenges of the nano era, we should be confident, not nervous!
