Bungee jumping, also called machine rope jumping, is a very exciting outdoor leisure activity recently. The jumper stands on a bridge, tower, tall building, crane or even hot air balloon with a height of more than 40 meters (equivalent to 10 floor), ties a long rubber strip with one end fixed to his ankle, then opens his arms, puts his legs together and jumps upside down. The rubber band tied to the jumper's ankle is long enough for the jumper to enjoy in the air for a few seconds. Free fall? . When the human body falls to a certain distance from the ground, pull and tighten the rubber rope to prevent the human body from falling further. At the lowest point, the rubber bounces again, and the human body is pulled up and then falls. This is repeated many times until the elasticity of the rubber rope disappears. This is the whole process of bungee jumping.
The origin of bungee jumping
The name bungee jumping comes from English? Stupid? Or? Bungee jumping? Why are there two names?
There are two possible reasons:
First of all, as far as we know, bungee jumping first appeared in Oxford Extreme Sports Club, and they called it bungee jumping. This sport is called bungy in New Zealand, probably because of spelling mistakes, but it is widely accepted in New Zealand because of its successful promotion, so the word bungy came into being.
The second statement: bungy is different from bungee jumping. The bungee cord is made of various materials. In North America, 5/8 inch military ropes are usually used, and the expansion rate can reach 265,438+00%. TR2 and ripcord are also used now, and the expansion rates reach 240% and 280% respectively. It is characterized by higher free fall, longer rebound time and better feel.
Bungy originated in New Zealand. The rope used is rubber rope (infinite expansion) and has a variable braking system, which can control the maximum expansion distance. It is characterized by low speed, high rebound and smooth feeling, which is especially suitable for ankle jumping.
Bungy/ bungee jumping should be a good transliteration word. In Hong Kong and Macau, people transliterate as? Stupid pig jumps? . The reason for this translation is that bungee jumping is transliterated in Cantonese. Stupid pig? The pronunciation is similar. Of course, it can also mean that only a stupid pig can jump. However, when the sport developed from its origin to all parts of the world, it was widely welcomed by people, and even some extreme sports fans had to put their weddings on the bungee tower. Li cheng? You can show the enthusiasm and loyalty of love by jumping. And people who go bungee jumping won't be called? Stupid pig? You can get it instead? Courage certificate? .
Around 500 AD, BUNLAP tribe of Vanuatu Islands in the South Pacific. In order to escape her husband's abuse, an indigenous woman climbed a tall cocoa tree and tied her ankle firmly with a local elastic vine. She threatened her husband to jump off the tree. Unexpectedly, the silly husband climbed the tree and jumped down. Naturally, the tender vine saved the woman's life, but the tyrannical husband died. Since then, it has become a local custom to tie vines to ankles and jump from heights. They tied up a 20-square-meter-long building with stumps and vines along the mountain. The 30-meter-high tower, from which young people swooped down, symbolized their maturity and prayed to the totem they believed in for peace and harvest of the tribe.
This form was later spread to England and was regarded as a performance of nobles in the palace. Performers must wear tuxedos and hats. The first bungee jumping with rubber rope was in America. 1954, two geographers came to Pentecost Island for a scientific investigation and accidentally discovered this strange custom of the island residents. Are they right in the scientific investigation report? Diving? The title is "An Incredible Jump in the South Pacific". On Pontecost Island, the locals climbed to the top of the mountain on Thanksgiving Day, tied them with ropes and jumped headfirst. ? Since then, the rudiment of bungee jumping has spread.
1970, geographers came to this island again. Photographer and writer Carl? Muller became the first foreigner to try this thrilling activity. He described that when he jumped from a height of 25 meters, he felt strangely as if he had stopped thinking. After being extremely excited, his body was slightly unwell. On April 1979, 1, members of the Adventure Club of Oxford University jumped off Clifton Bridge with an elastic rope, which opened the curtain of modern bungee jumping.
But bungee jumping really developed in New Zealand. As early as 1988, a? j？ Hector and Chris? Oran founded the first commercial bungee jumping organization, the Rebound and Jump Association, in New Zealand. Helian Bobo jumped off the Eiffel Tower, which aroused the world's interest in bungee jumping. That same year, John? Kaufman and his younger brother also set up a commercial bungee jumping organization in California. John himself was attracted to this industry by bungee jumping performance on TV. In less than three years, they attracted 65,438+6,000 people, each of whom spent $99 to participate in bungee jumping, and developed bungee jumping into various forms such as bridge bungee jumping and airplane bungee jumping. 1990, the balloon bungee jumping started again. Since then, this movement has been vigorously promoted. So far, many countries in the world have established bungee jumping bases, such as Singapore, Japan, Canada, Australia and some European countries. 1 May 19971day, bungee jumping was first introduced to China.
What kinds of bungee jumping can be divided into according to jumping methods?
1. waist-tied back jump This jump method is to stand on the platform with waist-tied and jump in the way of back jump. This jumping method is the first basic action stipulated by beginners. When I jumped, I seemed to fall into a bottomless pit, as if my whole heart was about to jump out. It suddenly bounced up in about 5 seconds, and the rebound lasted 4 15 times. After a pause, I saw that I was safely suspended in mid-air. The whole process is really about 1 minute.
2. Jump forward with your waist tied. This jump method is to stand on the platform and jump down with your waist tied. This jumping method is another attempt to be the first basic action of jumping beginners. This jump is similar to the back jump, but the bouncer is face down. When the player falls face down, he looks at the ground and listens to the wind blowing through his ears, and really feels the visual horror and helplessness. When skipping rope stops bouncing, you can really enjoy the joy of rebirth.
3. Foot-tied high-altitude diving is the coolest way for jumpers to show their heroic spirit. This jumping method is to tie the equipment to the ankle, and the jumper stands on the platform with his head down, just like the style of Olympic athletes diving. After counting down to 5, 4, 3, 2, 1, the jumper opens his arms and dives downward, just like an eagle spreading its wings, with extraordinary spirit.
4. Back somersault with feet tied. This jumping method is the most difficult but proud jumping method. This jumping method is to tie the equipment to the ankle, and the jumper stands on the platform with his back facing back. After the countdown of 5, 4, 3, 2 and 1, the jumper flips backwards with open arms. This kind of jump requires strong waist strength and full courage. If you think you are brave, you might as well challenge your courage after experiencing the jump of tying your waist and feet.
The bouncing coach described bouncing as the closest feeling to death. The bodyguard tied the equipment to his back, and after the countdown of 5, 4, 3, 2 and 1, he held his chest and feet with his hands and stepped down step by step, as if from the sky. Suddenly, he felt that the earth was hanging and things on the ground were getting bigger from small. The whole process is like dealing with death, which is really exciting and hidden to the extreme. Wait for you to experience it yourself.
