108:' trainer (until then, Phelps had held the world record for the 200m freestyle since 2007) suggested that Phelps boycott international swimming competitions until the suit is banned. Biedermann's breaking of both Ian Thorpe's 400m world record as well as Phelps's 200m record have been largely attributed to the superiority in the design of his swimsuit. Michael Phelps speculated that the new rules banning polyurethane will level the playing field once more, stating:

swimmer. Yet another innovation is to use material that squeezes and slims down swimmers "so the skin doesn't wobble around as they go through the water." Pieces of fabric were put through wind-tunnel tests to check for drag. Programmers used computational fluid dynamics to model the suits' aerodynamic qualities, as if they were trying to figure out how a brand-new jet will fly. Then, swimmers put the designs to real-world tests in tanks and pools.
141:, where 17 world records fell, it was felt there was a need to modify the rules surrounding swimsuits. The combined effects of the LZR both compressing the body and trapping air for buoyancy led to many competitors who used the LZR wearing two or more suits for an increased effect. This led to some claiming that the LZR was in effect "technological doping."

According to Rick Sharp, an exercise physiologist at Iowa State
University, "The Speedo team came up with a design that put panels of polyurethane over parts of the body that produce the highest drag. Another part is the suit design: You don't want a suit that traps water as it flows around the

in March 2009, FINA stipulated that swimsuits should not cover the neck, must not extend past the shoulders and ankles, and also limit the suits' thickness and buoyancy. In a statement FINA stated that:
