Improved Procedure for Estimating Time-dependent Changes in Local Sweat Rates by Measuring Local Sweat Volumes

Ueda H and Inoue Y

Abstract

Sweat distribution over 21 body sites in 8 young males was described by determining the local sweat volume (LSRap), measured using absorbent pads throughout 3 different bicycle exercises performed at 35, 50, and 60% VO2max for 40 min, at 30°C and 50% relative humidity. The local upper back sweat rate was concurrently measured by the ventilated capsule method (LSRvc) in parallel with the absorbent method. The LSRap at the upper back correlated strongly with mean LSRvc at the position immediately above the absorbent pad (p
