Comparison of sweat onset time for AXR1, sweat rate (AXR1, AXR2 and DIR), activated sweat gland density and activated sweat output per gland.

Values are mean ± standard deviation. *P<0.05, ***P<0.001; significant difference between groups. DIR, directly activated sweating (muscarinic receptor mediated sweating activity) 6–11 min; AXR, axon reflex-mediated (indirectly activated) sweating (nicotinic receptor mediated), AXR1, measurement from 0–5 min, AXR2, measurement from 6–11 min; Trained (n = 16 male long-distance runners); Control (n = 20 control males).
