Increases in sweat rate during exercise: Gland recruitment versus output per gland

Abstract

1. 1.|Increase in exercise intensity result in linear ( r = 0.82) increases in whole-body sweat rate. 2. 2.|The total number of active sweat glands recruited increases significantly ( P < 0.05) with increases in exercise workload. 3. 3.|Mean sweat rate per gland is unchanged ( P > 0.05) with increases in exercise intensity. 4. 4.|Whole-body sweat rate is linearly ( r = 0.84) correlated to the number of active sweat glands recruited during exercise.
