Estimation of sweat rates during cycling exercise by means of the closed chamber condenser technology.

Background/aim: Knowledge of local sweating patterns is of importance in occupational and exercise physiology settings. The recently developed closed chamber condenser technology (Biox Aquaflux ) allows the measurement of evaporative skin water loss with a greater measurement capacity (up to 1325 g/h/m ) compared to traditional evaporimeters. The aim of this study was to evaluate the applicability of the Biox Aquaflux to estimate sweat production during exercise.
