Abstract

The purpose of this study was to demonstrate the effect of different suits on drag for Olympic level swimmers. The effect on drag for some suits were with 5-7% rather large given the small differences observed in competitive time during Olympic finals. It is also found that the same suit may have a drag reducing effect for one swimmer while for the other no or a detrimental effect on drag is observed. Apparently, the simple reasoning to create a level playing field for all swimmers that one suit must be available for all is not as simple as the present FINA rules suggest.
