Competitive swimmers use the term fast pool when they are describing a pool that has a good gutter system on the sides. This system allows the water to flow out easily and doesn't allow waves to bounce back to the middle of the pool. The lane lines can also help control the waves and the deeper the pool is, the fewer waves hit the bottom and bounce back up to the surface. The lack of these waves provides less drag/ resistance for the swimmers, which gives them a faster time.

Studies shown that the shark is fast in the water but not naturally hydrodynamic. The shark's quickness is attributed to V shaped ridges on its skin called dermal tentacles. These ridges decrease dray and turbulence around the shark's body, allowing more efficiency. The result of these studies has brought a brand new fabric to the market for competitive swim wear. Speedo has produced a fabric that emulates shark's skin. This fabric reduces drag and turbulence around the body, which helps a swimmer pass through the water more effectively. The suits made from the “Fast skin” fabric have only been on the market for a little while but are already changing the look of competitive swimming and its results.
