Bobsleigh




Bobsleigh is a winter sport which was discovered in 1860. It is found in England but the first track was made in Switzerland. First were straight lines and the bobsleigh was not controled. The races were influenced only by the speed which competitors reach in the beginning by pushing the sleigh forward. Then sport developed and they begun building new tracks with curves where the high of the trackwas bigger to be saver for the competitors. Bolids were made to can be controled from the driver who sits in front of the sleigh. There are four slides under the sleigh and first pair of them are controled from the driver who uses wheel to turn the bolid in different sides. This sport have participated in the Olympic games since the 1924 year when this sport reached our days level. Now this sport is only developed to be safer for the competitors. There are two types of bolids for different number of people. There is a bobsleigh with four person whose weight is 630 killograms and other one with two persons whose weight is 385. Because of its weight the bolid with five persons reaches higher speed in the race. Firstly because they are four people which push the bolid and second the havier bolid is faster because of different forces which influence it. During a race the watch counts every thousand of a second because bolids finish with a small distance between them. This mean that a small mistake in every moment could put the team on the end of the list. During the streinghten the racers should get in the bulid in appropriate time becuase they loose important seconds.
During the last Olympic games was entered in new 5 placed bolide. Although this sport gets savier every year 3 persons loose their lifes per year. This year at the winter olympic games one competitor dead during the training for the next race. He jumped from the curve and there was no chance for life because he broke his neck. This sport is dangerous but interesting and with lot of fens so more and more players are fighting for the world champion cup.
