Can you imagine the very first modern Olympics in 1896with no landing mats （海綿墊），no stopwatches and no photo finishes？In fact，cameras and stopwatches were not used until the 1932Olympic Games in Los Angeles，USA．Thanks for technology，Olympics have been developing at an unbelievable speed．
Today technology has completely changed sports．Take sports equipment for example．Electronic eyes hanging at the starting lines，together with digital cameras，could catch correct race time and also help to catch runners who"jump the gun"．As runners cross the finishing line，special digital cameras can also easily decide the winner．The days of"dead heats"are gone．
Technological developments are also good for athletes．New sports suits，which get less wind effects，can help cut up to one-tenth of a second from runners'race time．Top athletes，like Liu Xiang，are even provided with hand-made sports shoes．These shoes are made to fit the athlete exactly--and there are some more changes in the shoes that meet each runner's personal needs．
Technology has also changed the way of many sports．Take one example--the pole vault．The landing mat makes a big difference to the vaulting style as athletes no longer need to worry about hurting themselves as they fall．Without these worries，athletes could jump higher．New swimming pools have been used to help swimmers swim with easier effort and sports scientists have worked out a new swimming style to improve the speed．
The increasing technological developments have led many sportsmen to suggest that the"Olympic spirit"is being lost in a rush to break records and win medals．Many developing countries say that technology has become too important in sport and that athletes from developing countries are disadvantaged．There are no easy answers but one thing is sure--we cannot turn back times．Technology cannot go backwards．
