No Bubbles To Eat

An excerpt from my blog today…

Bubbles are evidence of turbulence. Bubbles mean there are voids in the water, which means there are low-pressure zones in that volume. Essentially, bubbles mean ‘low-traction’ zones. For a high diver this is good news. For a swimmer this is bad news.

A swimmer creating bubbles with each kick or stroke is the equivalent of a car spinning its wheels in the mud or snow. Bubbles mean there is less firm water to press against. In order to overcome the loss of traction when pulling air down with each kick and arm entry the swimmer has to exert even more effort to make up for it. Bubbles are the product of in-accurate movement patterns and lead to considerable unnecessary waste of energy.
