Abstract
Modern biotechnology and nanotechnology are conducive to the selection and training of athletes, promote the development of Sports Biological Science, and effectively improve athletes’ sports ability. In this paper, the main study of modern biology and nanotechnology on the impact of competitive sports. In this paper, eight boys were randomly divided into two groups, one group wore the swimsuit made of nanofiber materials, the other group wore the swimsuit made of common clothing materials for three swimming competitions. The experiment found that in the first competition, the results of the Nano group were mostly higher than the ordinary swimsuit group. Only the No. 3 player in the Nano group scored 9.23 s, which was lower than the 8.99 s of the No. 3 player in the ordinary group. In the second competition, the performance of the Nano group is still higher than that of the ordinary group, except that the No. 2 player in the Nano group has a score of 10.22 s. In the third time, the four members of the frontier Nano group achieved higher scores than the ordinary group. The No. 3 player in the ordinary group had a large error in the results, which was not meaningful.According to the results of the three competitions, under the control of variable factors, the results of nano group are much better than those of ordinary group. The results show that nanotechnology and modern biotechnology can effectively reduce the unnecessary energy consumption of athletes in the competition, save the competition time, and bring new vitality to competitive sports.
