Bobsleigh: Adrenaline on Ice

Gliding with a sled a sunny day in winter in Park Hill around grandma is definitely fun. One mistake, one wrong move and the soft snow makes the job of cushioning the blows. But at 150 km / h in the cold, hard ice, the story changes. Adrenaline is triggered, the senses are defendants peak and any mistake could be your last mistake. Like everything mortally dangerous, many people choose it, enough so that the bobsleig be considered a winter Olympic sport. Here his presentation:
Like the luge and skeleton, its origin is in the Swiss Alps in the late nineteenth century. Specifically the first world bobsleigh club was founded in 1897 in St. Moritz, Switzerland and from there spread to other parts of Europe. The first official competitions can consider dating from 1914.

In the early decades of the bobsleigh had little to do with what is at present, as the materials, the design, the tracks have completely changed almost beyond recognition. Major breakthroughs came in the field of materials, in two respects: the new sleds steel and fiberglass manufacturing of which utilize the latest technological advances in aerodynamics, and not least, the artificial slopes in which you can achieve truly amazing speeds with which they had never dreamed the first practitioners of the sport. The ice rinks are narrow passages, tortuous and stilted, with a number of left and right turns.
The key in the bobsleigh is normally at the start. It is critical that these first few meters the crew get the highest possible speed pushing the sled in those initial meters, so they should also be fast, strong people, and that usually depends on the initial explosion the result. The differences between participants rarely exceed a few hundredths so any little mistake is impossible to recover. Although the sled has a brake, this is only used when passing the finish line. Speeds often exceed 150 miles per hour and runners support up to 4 or 5 forces "G".
