After reading a lot of articles and participating in online forums, it seems some people are making assumptions that the advancement in technology within the new swimming costumes are to be accredited for the huge advancement in swimming and the breaking of all the world records.

Having swam at top levels myself I can say, that the costumes have a very small impact on your performance, yes they are defiantly a help, and actually help by holding your muscles tight rather than create less friction through the water as most people think. They also aid performance as a mental boost, but all in all the new swimming suits don't help out as much as people are making out! The swim suits give just fractions of a second off your times where as just the development and progression in the sport and performances within the pool along with training advancements and training equipment makes up for the bulk of the improvements.
