After eating, he exercised again, took a lot of meat and put it in his backpack, and soon came to the edge of the cliff. The audience friends were very curious about what he was going to do. Brother De, are you here for a walk or to see the scenery? Stand Where and what?
Said, "My friends, you have also seen the cliff here, and I will climb down from here."
The camera shot down, and there was a white mist below that fascinated their eyes, and they couldn't see how deep it was at all. Holding the grass, Brother De really wanted to climb down from here, right?Isn't that dangerous?Shouldn't I start climbing those dangerous places again and play extreme sports?You may have forgotten how to write the word dead.
After exercising for a while, breathing heavily, with the backpack on his back, his entire aura has changed.
It's not an extreme sport, it's a death sport.
He went down slowly, not daring to be careless, what is extreme sports?It is a general term that combines some difficult and challenging combined sports, such as: downhill, skateboarding, extreme cycling, rock climbing, snowboarding, air surfing, street rapid descent, parkour, extreme off-road, extreme Water skiing, extreme roller skating, drift board, etc. are all extreme sports.
Extreme sports are evolved from a number of shaping sports and various actions in games, life and work, and are highly difficult spectator sports with young people as the main participants.In the process of integrating with nature, human beings use modern high-tech means to maximize their physical and mental potential and challenge themselves.
It is adventurous and exciting. In addition to pursuing the spirit of "higher, faster and stronger" that surpasses the physical limit of competitive sports, it also emphasizes participation, entertainment and bravery, and pursues the pleasure obtained when crossing psychological barriers. At the same time, it also reflects the good wishes of human beings to return to nature, return to nature, and protect the environment. Therefore, it has been hailed as "future sports" by countries all over the world.
It also has a sophisticated history in China. Its full name is "CHINA X-GAME", abbreviated as "CX".First organized by the China Extreme Sports Association in 1999, it is the authoritative event of extreme sports in China and a carnival for extreme sports professionals and enthusiasts.
"Extreme sports themselves can be divided into broad and narrow senses. Some challenging non-Olympic and non-World Games events can be called extreme sports in a broad sense, such as bungee jumping, rock climbing, cliff diving, etc. But extreme sports in the narrow sense only refer to various large-scale extreme sports. The established events included in the sports meeting, such as extreme motorcycles, extreme roller skating, etc., because these extreme sports in the sports meeting have been developed in scale after a long period of systematic development, the organization is strict, the rules are perfect, and the competition is reasonable, so many projects are gradually Absorbed by large-scale comprehensive sports events, such as BMX racing has become an Olympic event, and snowboard U-shaped pool is also an official Winter Olympic event. Then these extreme events have two origins, one is formed by a forming sport For example, extreme motorcycles are differentiated from motocross, extreme skiing is evolved from ordinary skiing, and so on.
While others evolved from games, life and work, such as skateboarding, rock climbing and so on.There are many extreme competitions in the world, but the most well-known one is the EXPN extreme competition held every summer and winter. Every year, there are some subtle changes in the competitions. Some emerging projects with well-organized and well-established rules are constantly being absorbed. And some projects that have already been carried out very widely and have a strong mass base have been invited. For example, inline skating is no longer a project of EXPN, which is why.
Many extreme sports are just born in recent decades and are in the ascendant. According to the season, they can be divided into two categories: summer and winter. The field of sports involves the multi-dimensional space of "sea, land and air".
The main competitions and performances of extreme sports in summer include: BMX, skateboarding, difficult rock climbing, speed rock climbing, air skateboarding, alpine gliding, water skiing, rapids kayaking, motorboats, surfing, jet skis, bungee jumping, roller skating and U jumping Race and block race, 100 meters and 200 meters and other sports.Due to the characteristics of "harmony between man and nature" of "integrating into nature (nature, environment, ecology, health) and challenging oneself (positive, brave, joyful, stimulating)", extreme sports are so popular in European and American countries It can be described as crazy and magical.Take water skiing and skateboarding as an example. In the United States alone, there are 110 million water skiing enthusiasts. Professional water skiing teams and performance teams are scattered all over the world. They have become an important urban cultural "dinner" in many cities; and skateboarding There are as many as 450 million enthusiasts in China.Because skateboarding is too thrilling and exciting, in the 20s, skateboarding was strictly prohibited by the governments of relevant countries, and it was once reduced to an "underground project". "The comeback is so powerful and influential that it has become a "money printing machine" in the eyes of many smart manufacturers.Skateboard superstars Tony Hawker (Tony Hawker) and Andy McDonald (Andy McDonald) are undoubtedly the same super idols as Jordan (basketball) and Pete Sampras (tennis) in the eyes of many young people.
The results of some sociologists' surveys and research on extreme sports show that: standing at the threshold of increasingly cruel competition at the turn of the century, facing the era of knowledge economy with information explosion, the pace of life of modern people is getting faster and faster, and the pressure of work is getting higher and higher. The living space is getting bigger and bigger, and the living space is getting smaller and smaller. The real environment makes modern people overwhelmed, and the continuous and increasing stimulation makes people's sensory boundaries continue to increase.The original feeling is not strong anymore, and I can no longer adapt to the pursuit of human beings.
From ballroom dancing in the 70s, disco in the 80s, to bowling and saunas in the 90s, they can no longer meet people's growing sensory needs.On the one hand, people need to seek excitement, vent pressure, and release energy. On the other hand, people are accustomed to general stimulation and enjoyment, and it is not surprising.At this time, people begin to pursue more intense stimulation, so as to obtain the desired feeling and arousal.The rise of extreme sports just meets this human need.Human beings have created civilization in the embrace of nature, but civilization is keeping human beings away from nature.Perhaps it is because human beings have lived in a civilized world far away from nature for too long, and after gradually falling into physical and mental laziness in the convenience brought by urban civilization, they began to desire to return to nature.
The urban trendy people who can't hold back their emotions are the first choice to break out of the blockade of urban civilization, to have a dialogue with nature, to restore the true nature of human beings as a member of nature, and to express the most essential capabilities of human beings.The rise of extreme sports just meets this human need.In addition, compared with traditional sports (including the Olympic Games), extreme sports are more self-challenging, exciting to watch, permeable to high-tech, and commercially viable beyond physical and mental limits.
When the essence of sports is more and more covered by the light of money; many Olympic sports are gradually troubled by many problems, such as fraud, black whistle, doping, bribery scandals, etc.; sports delight the body and mind, improve human nature, The essence of returning to nature has been gradually downplayed; sportsmanship has suffered unprecedented doubts and a crisis of trust.However, in the non-mainstream sports that are out of sight of the general public, there is hidden a clear stream of returning to nature, integrating into nature, challenging oneself, and achieving the ideological realm of "harmony between man and nature"——extreme sports, which are popular in European and American countries and other countries. In developing countries, it has quietly become the most popular and lasting fashion sport among urban youths. Participating in extreme sports games has become the dream of most urban youths.
The rise of extreme sports has made people gradually leave traditional sports venues, go to the wilderness, indulge in the mountains and rivers, and seek the essential meaning of human existence from nature.Outdoors alone, the extreme sports presented in the form of adventure have become a space for people to surpass themselves and challenge their limits: jet skis and surfing, allowing you to fully experience the chicness of racing against the waves in the blue sky and clear water; Boating and white water rafting allow you to experience the thrill of rushing thousands of miles and turbulent waves; bungee jumping and rock climbing make you feel the thrill of "jumping towards gravity and soaring down"; Here, we abandon the comfort and laziness brought by modern civilization, have the ability to coexist with nature, and fully experience the joy of returning to human nature and original intention and testing human wisdom and strength.
There are two types of extreme sports competitions: Park Race (PARK) and U Board Race (VERT). PARK is a venue with a certain size range, with a jumping platform or other equipment of various shapes for players to perform competitions; and U-board is a U-shaped half-pipe equipment for players to perform. Come to perform.The International Standard Specification for Extreme Sports Venues divides sports venues into Class A, which meets international competition standards and can hold international competitions, Class B, which is standard, which can hold general competitions, and Class C, which has simple facilities and is suitable for beginners.
The above discussion is mainly about the extreme roller skating event (that is, the B3 event), and the design performance requirements for the SKATE PARK venue are as follows. "
Rhodes talked endlessly, and the audience friends were all dumbfounded, did you f*ck copy the Internet?Or do you study extreme sports day and night without eating or drinking?Otherwise how do you know so much?

Compared with ordinary ball games, extreme sports competitions have a very short time. Generally speaking, players only have two rounds of 60 seconds to perform. It is really not easy to take into account the fluency and difficulty of movements in tricks.The distribution of extreme sports scores is roughly as follows. For details, please refer to the international extreme sports competition rules: extreme cycling, skateboarding, and inline wheel park competitions: - 60 points for air movements - 40 points for card, point, and grinding movements - 40 points for personal style - Course 10 points extreme bicycle floor competition: -skill 10 points-stability 60 points-personal style 20 points-route 10 points extreme bicycle, skateboard, inline wheel half pipe competition:-air action 10 points-card, point, grinding action 50 points-personal style 30 points-route 10 points In the official competition, 10 referees are used as the principle. The score is the average of the 5 referees after the scores of the [-] referees get the highest and lowest scores. The highest round of the two rounds, if there is the same In the event of a score, the ranking will be calculated by the average score after deducting the lowest score from the three referee scores.
Main sports: Roller skating, also known as roller skating and roller skating, is a sport in which special shoes with rollers slide on hard surfaces.Most roller skaters today mainly use inline rollers, also known as brushes, 66, (the other name for inline roller skaters for this sport comes from the sound made when the wheels rub against the ground during skating, and at the same time It is also called "brush" for skates, and "street brush" for skating on the road, and 66 is the same as yo-yo, which is more interesting and fluent, and is mostly called by lovers).Therefore, inline skating has almost become synonymous with roller skating.
Can exercise, enhance physical fitness, eliminate fatigue, adjust the spirit.
Invented by American James Plipton in 1863, it was quickly introduced to Europe and the rest of the world.The roller skating event held on the roller skating field is the figure roller skating.Speed skating is divided into two types: road racing and track racing.
In the eyes of ordinary people, the female players who participate in the extreme sports roller derby must be girls who tend to be masculine.In fact, these girls are not only quite courageous in roller skating, but also have superb roller skating skills, and their beautiful appearance and slim figure make people want to take a closer look.
