The "black science and technology" on the Olympic field
The "black science and technology" on the Olympic field, with the continuous investment in sports and more and more scientific training, now the world record is basically close to the limit of human beings, break the world record! This thing is becoming more and more difficult. High-tech sports equipment, is attracting more attention.
The Olympic Games on the "black technology" 1Beijing time in the early hours of the 13th, China won the women's field cycling team speed race championship. Two Chinese girls, wearing Chinese-style sports helmets, collected the first gold medal in China's cycling Olympic history.
In addition to the helmets, to attract the attention of the audience, and the girls under the feet of the bike. This bike has only one gear, no brake, high technology, the purpose is to allow athletes to "fast to fly".
High-tech sports equipment, is attracting more attention. Dr. Huang Xifa, an associate researcher at the Institute of Sports Science of the State General Administration of Sport and general manager of the Beijing National Sports Science and Technology Development Service Center, has been paying attention to the "black science and technology" in the Olympic Games. His most urgent expectation is that more Chinese companies will participate in the research and development of sports technology products.
More high-tech equipment for daily sports training
This year's Olympics, the volleyball court used the Hawk-Eye system, to solve the possible disputes; long-distance swimming competitions under the pool, the use of LED displays, thoughtful to tell the athletes how much distance they have left to reach the end; shooting range The use of laser electronic target system, data accuracy is further improved ...... Olympic Games before and after the stage, all kinds of cool stuff on stage. If you have them all, you can probably open a technology expo.
Of course, these are just the tip of the iceberg for competitive sports technology products.
More and more "ruthless" technology, used in the daily training of athletes. The so-called "know your enemy, know your enemy, not dangerous", athletes to understand their own strength and opponents; coaching team to master the technical characteristics of the athletes, physical condition, the development of scientific training programs. Behind a medal is a set of scientific training system.
"We use the most is the video analysis technology." Huang Xifa said, now the mainstream video acquisition frequency of 50 frames per second, if the analysis of specific behavioral points, it can be 500-1000 frames per second high-speed camera to capture and collect the movement of athletes, and analyze the technical indicators of athletes in all details. He remembers, when Liu Xiang's coaching team, with the camera to capture its dynamics, Liu Xiang in the 110-meter hurdles training running the whole process into a map. They looked at the full picture of "Liu Xiang" and analyzed whether his actions at each key point were in place.
The development trend of sports equipment: intelligent and invisible
Advances in technology have indeed led to a significant increase in sports performance. 1963, thanks to the use of glass fiber reinforced plastic poles, the performance of the pole vault event increased by more than the total of the past 20 years. Now, however, sports equipment has reached the limits of what can be achieved in terms of material improvements and ergonomic design optimization. Unless new materials are used, it will be difficult to revolutionize the sport.
At the same time, intelligence has become a new trend in sports equipment. In recent years, wearable devices have become a professional athlete training assistant. Huang Xifa introduced, in soccer training, athletes will wear an undershirt with built-in sensors, the coaching team will be able to monitor their running distance, running speed, running track and heart rate and other data.
Huang Xifa judgment, the future of wearable devices will be more invisible, and even become part of the clothing. These devices in the future can not only "passive record" data, but also on the athlete to impose "active stimulation" to enhance their excitement.
In sports technology, China is also "holding back".
For example, this time in the Olympic Games on the laser electronic target, is not new. Domestic companies have developed a laser electronic target system with international intellectual property rights. And then the swimming program, has been the use of Omega's video image timing judgment system. Huang Xifa revealed that the Institute of sports science and technology, the national body of science and technology is cooperating in research and development of video images of touch wall timing judgment system and swimming underwater action analysis system, the relevant hardware and software at the end of this year will be able to test run in the swimming team.
The development of mass sports can also enhance the competitive sports technology paradigm
Pictures from the network
Beijing National Sports Science and Technology Development Service Center market manager He Cong frankly, in this regard, wearable devices, China's enterprises did develop a good . Products. But in terms of algorithms, or foreign companies are better. "They a device can analyze the indicators, up to more than 300; domestic companies if you can analyze to more than 40, it has been quite good." Technically, China and foreign countries are not without gaps.
In the field of mass fitness, the performance of Chinese companies is noteworthy. However, due to the relative limitations of the audience, the pace of development of competitive sports equipment in China is really not as good as abroad.
"In the past, it was every man for himself. Sports people play sports themselves, do their own research, social forces involved in relatively little. Now advocating 'Internet +', some large companies are also involved, the situation of playing alone is changing." Huang Xifa said.
He Cong said, when sports is a minority of the "game", few companies are willing to go to the trouble of research sports equipment; and when the real popularization of sports, see the business opportunities, companies are willing to invest. The results of this investment, applied to mass sports at the same time, to upgrade, can also be used in competitive sports. Of course, you can also take the "top-down" route, the enterprise first in competitive sports to seek a place, the sports equipment "downsizing" and then pushed to a wide range.
"With the development of the sports industry, and then take the wind of the Olympic Games, I believe that more and more companies will enter the field of sports equipment research and development, the formation of a spurt of development." Huang Xidong hopefully said.
With the continued investment in sports and increasingly scientific training, the world record is now close to the limit of human beings, and the matter of breaking the world record is becoming more and more difficult.
To achieve better results, in addition to the hard work of training, we also look to other ways, such as high-tech equipment.
Let's take a look at some of the high-tech gear that has appeared at the Olympics in recent years.
Doping
The infamous doping is not technically equipment, although it is "high tech", but it must be mentioned.
In the 1920s, doping appeared in the Olympics, and athletes were proud of it for a while.
During the Cold War, the rivalry between the United States and the Soviet Union also extended to the Olympic Games, where doping reached its peak as US and Soviet athletes competed for results. This made the competition unfair and seriously violated the Olympic spirit. More and more people recognized this, and the 1988 Seoul Olympics became a turning point for anti-doping, and since then there have been huge advances in doping detection technology, and by the time we come to the 2021 timeframe, the anti-doping effort has made great strides, but it has not been completely eliminated.
Sharkskin swimsuits
Sharkskin swimsuits first appeared at the Sydney Olympics in 2000, when Australia's Thorpe won three gold medals in them. This suit is said to increase the speed of swimmers by 3%, and this is only the first generation of sharkskin swimsuits, later also developed to the fourth generation.
Sharkskin swimsuits are a success story in the application of bionics. Scientists have found that the rough V-shaped folds on the surface of the shark skin can greatly reduce the friction of the water flow, so that the water flow around the body more efficiently, the shark was able to swim quickly. Sharkskin swimsuits are made with a micro-stretch fiber surface that is modeled after the surface of a shark's skin.
In the prevalence of sharkskin swimsuits, the swimming record of the century has been repeatedly broken, the biggest beneficiary is the legendary American swimmer Phelps, in the sharkskin swimsuits, wildly 23 Olympic gold medals, no one has ever seen, and I believe that it is difficult to come back.
The turning point of the matter is in 2019, July 28, Phelps was beaten by Germany's Biedermann, who wore a more advanced sharkskin swimsuit, in the 200-meter freestyle final at the Swimming World Championships, and the myth of Phelps was ended. Later, under strong public pressure, FINA made a decision at the end of July 2009 to "ban the use of high-tech swimsuits in competition from 2010".
Specialized race suits
Sprint stars such as Marion Jones of the United States and Cathy Freeman of Australia use special race suits developed by Nike. These suits are very sleek and have a hood that covers all parts of the sprinter's body except the face, arms and legs. This can play a role in muscle insulation and compression to improve the performance of sprinters.
Australian marathoner Steve Moneghetti wore shorts and a tank top made from recycled soft drink bottles, which according to the manufacturer, Nike, are cooler than other fabrics.
The U.S. football and volleyball teams even borrowed NASA technology for their uniforms. The jerseys have a built-in mesh structure that absorbs heat and quickly expels it into the air.
Nike also provides many athletes with anti-air resistance suits to help sprinters reduce air resistance and achieve improved performance. The design process uses new technologies like wind tunnel testing and 3D printing.
Of course, our Chinese team is not doing nothing, the national track and field team uniforms used Nike's AeroBlades technology, the technology in the uniforms of the legs and arms on both sides of the increase in a one by one "small triangles" in the movement of athletes, these inconspicuous small triangles can be
In addition, the Chinese team's uniforms are also said to use black technology - the material of this uniform can effectively enhance venous return, reduce blood stasis, accelerate metabolism and achieve short-term recovery of human energy.
Specialized Running Shoes
Donovan Bailey, the Olympic champion in the 100-meter race, wore special running shoes made by Adidas. The special running shoes are claimed to have a hard metal plate that keeps human toes as stiff as a jaguar's claws during a race.
American sprinter Trayvon Bromell wears New Balance 3D-printed running shoes with spikes, and Kenyan sprinter David Rudisha wears Adidas Adizero MD running shoes, which are ****er, lighter, stronger, and able to improve stability and speed when running.
LumiWave Wearable Therapy
LumiWave is an infrared wearable therapy device that uses shimmering light to help reduce pain, especially for strains, sprains, and inflammation of the joints, and allows for rapid recovery. LumiWave was first popularized within the Olympic team back in 2004.
Specifically, the device is equipped with 50 infrared LEDs, and when an athlete puts LumiWave on his or her body, the device emits pulses to increase blood circulation to the injured area, which further enhances the body's release of nitric oxide, and ultimately speeds up the recovery of individual cells.
Solos Smart Glasses
Solos Smart Glasses is a smart device similar to Google Glass that is so popular among cyclists that it is now being used by US cycling teams.
Specifically, the plain-looking glasses are tweaked for cyclists, with a built-in heart rate sensor that monitors an athlete's heart rate, calories burned, and also provides real-time navigation, as well as phone capabilities. Like Google Glass, Solos' display is projected directly onto the lenses of the glasses, quantifying the movement before giving personalized advice accordingly to the athlete's state, thus helping them adjust their cadence and speed.
Jelly headgear
Synchronized swimming is one of the most enjoyable of the many Olympic disciplines, and it's important for athletes to look good. If the hair into the water unfortunately spread out, the cape hair will be detrimental to the image. And the use of ordinary hairspray effect is not significant, but it is not difficult to defeat the smart athletes, they use actually jelly!
The "jelly" used by the girls is actually a sugar-free jelly powder-gel. The gel is a semi-solid, thick substance with no flow properties. Before the competition, the gel is whisked together with warm water and brushed onto the head in layers until each strand of hair is fully immobilized by the gel.
The "cryo-pod"
The "cryo-pod" gradually reduces the temperature to -140 degrees Celsius, and athletes wear special socks, underwear, and earmuffs. Athletes enter a small room, which is gradually moved into colder and then coldest chambers. The extreme cold temperature narrows the athlete's blood vessels, slowing down blood flow and metabolism, and when the athlete leaves the chamber after two minutes, their blood vessels expand to four times their normal size, and the blood circulates through the body with more oxygen, healing damaged or overworked tissues and joints. and at the same time, endorphins are inhibited by the cold temperatures, which is great for pain relief." Because of the significant effect on physical recovery, cryo recovery is used in some endurance programs such as long-distance running and swimming.
"Plateau Tent"
"Plateau Tent" is a large tent can play a role similar to the role of hyperbaric oxygen chamber, this large tent has a set of oxygen This tent has a set of oxygen circulation system, power work, the oxygen content of the tent is reduced compared with the outside environment. The tent can simulate the environment of plateau training on the plains. Plateau training can make an athlete's cardiorespiratory fitness strong, but usually, after returning to the plains for about three weeks, an athlete's condition will decline to varying degrees. The way to ensure the quality of plateau training and avoid the decline is to use a "plateau tent".
