Characteristics of sweating responses and peripheral sweat gland function during passive heating in sprinters.

摘要: The purpose of this study was to compare sweating function in sprinters who have trained for several years with untrained subjects and endurance runners. Two separate experiments were conducted. Nine sprinters, eight men, nine distance runners (\(\dot{V}{\text{o}}_{{ 2 {\text{max}}}}\) 50.9 ± 1.4, 38.2 1.8, 59.1 1.2 mL/kg/min, respectively; P < 0.05) passively heated 50 min (Experiment 1), ten 11 men (similar \(\dot{V}{\text{o}}_{{ levels compared Experiment 1 each group) had their sweat gland capacity assessed based on acetylcholine-induced rate (SR) 2). slope the mean non-glabrous SR plotted against change body temperature during passive heating did not differ significantly between (1.21 0.10 0.97 0.12 mg cm−2/min/°C, respectively); contrast, exhibited a greater (1.42 0.11 0.05). threshold different among groups.

Thus, there is case that daily training sufficient improve relative those
