"... In a separate group of swimmers (nine who shaved body hair and nine controls), removing body hair significantly reduced the rate of velocity decay during a prone glide after a maximal underwater leg push-off. It is concluded that removing body hair reduces active drag, thereby decreasing the physiological cost of swimming. [Link]Who knew that body hair was the "moral" equivalent of "barnacles" on a "boat's hull?"
