SPORTS
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".
SPORTSMan always has managed to harness the wonders of nature to entertain. With ropes and carabiners challenges the verticality of high walls and cliffs. With an oval carbon fiber table mounted huge waves in the turbulent seas. That
if large polished stones together with long brooms and devise a sport
on ice, if it is to capitalize on the endless imagination of man. Curling undoubtedly first prize to human ingenuity.
Curling
is a precision sport similar to bowling British, Chilean hopscotch, at
River Plate or bocce balls Venezuelan native, practiced in an ice rink. Two teams of four players compete against each other by sliding granite stones August 20 kg each on a ice racer.
Once
the launch, the other team members (sweepers) provided brushes
accompany each stone to acting on 
the ice surface, facilitating its
progress or change its direction, but still not touching the stone. After
making all the throws, points are awarded based on the proximity of
these stones to the target in the center marked down the hall. For
example, the stone closest to the center of the target, has a point, if
the following is from the same team, they have two, and so on until the
following is the opposing team. By this rule, if a team has to finish the "end" to 0. In case no stones in the target is considered to 0-0. A normal game is played from 8-10 "ends" or sleeves. At the end of the match wins the highest scoring team in the event of a tie, we decided on a bonus manga. The team that wins a sleeve begins the following mandatory.
It is believed that the game of Curling was invented in late medieval Scotland. The
first written references to the use of ice stones appear in the
engravings of Paisley Abbey dating from February 1541 and it is known
that it was a very popular outfit in Scotland between the sixteenth and
nineteenth centuries. The first World Curling Championship was exclusively for men and was called, "Scotch Cup". It was held in Edinburgh, Scotland in 1959 and was won by the Canadian team. Today
it is practiced mainly in Canada (came from the hand of Scottish
immigrants), the northern United States and northern Europe.
