SHAVING REDUCES THE PHYSIOLOGICAL COST OF SWIMMING
Sharp, R. L., & Costill, D. L. (1990). Shaving a little time. Swimming Technique, November 1989-January 1990, 10-13.
Physiological measures were taken in trained swimmers performing a pace-controlled 400 m breaststroke swim under conditions of being shaved and unshaved. Two groups were compared.
Results showed that the physiological effort of swimming decreased in the shaved condition. Also:
Implication. Shaving before major competitions provides a measurable physiological advantage for swimmers primarily through the reduction of active drag.
