SHAVE OFF SECONDS
Before hightech suits were authorised, swimmers had a very good reason to shear their chests smooth due to something called ‘laminar flow’, the ease with which fluid can pass around an object. Water is 1,000 times more dense than air and therefore requires a perfectly smooth surface to cut through it.
Scientific studies have shown that removing body hair dramatically optimizes laminar flow. It can have a great impact on the distance achieved with each stroke and, in an Olympic race, that 100th of a second can make all the difference!
