Background: Swedish experts have pioneered a new machine will enables coaches to study the style, performance and body reaction of a swimmer under standardised conditions.
SYNOPSIS: Swedish Olympic champion Gunnar Larsson -- gold medallist in the 200 and 400 metres medley at the Munich games -- was one of the first swimming guinea pigs. After studying the conditions during Larsson's winning swims in 1972 the experts ordered him into the machine.
Basically the machine is a water tank. 10,000 gallons of water and a depth of four feet. At the bottom of the tank are two propellers which can be regulated to create various water speeds. They can create a flow of a swimmer doing up to 50 seconds for 100 metres. What happens is, the swimmer goes through the motions and if he can't keep up with the speed, the water washes him back. It's a bit like the endless belt used for training athletes.
The machine hooks up to a video tape system and the tapes are used to point out faults in the swimmers' techniques. Swedish coaches believe the East Germans have similar machines in use, and think the machine had a lot to do with their success in the Montreal Olympics. The machine's greatest advantage could be in teaching children to swim. The Swedes believe it could even eventually begin to replace of swimming pools.
