Verbessertes Verfahren zur Schätzung zeitabhängiger Änderungen der lokalen Schweißrate durch Messung des lokalen Schweißvolumens

Ueda H und Inoue Y

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<0.05). There were significant differences in LSRap among the 21 body sites within each exercise intensity (p<0.05). Regional comparisons showed a greater LSRap at the chest and back and lower LSRap at the flank, thighs, and legs. Moreover, LSRap was distributed symmetrically and was greater in the middle compared to the adjoining lateral sites. LSRvc data reanalysis of our previous studies on prepubertal boys, men, and women across a range of ages revealed that during passive and/or active heating, the LSRvc were arranged in order of lower limbs.
