Eleven college-aged male subjects with a mean maximal oxygen uptake of 48(range 42-59)mlkg−1min−1 performed three sessions of 20-min cycle exercise at two levels of intensity (40 or 60% $$\dot VO_{\rm 2max}$$ ) in a room maintained at 31°C. The chest sweat rate (SRch) and its containing Na+ were higher and individual differences in SRch and [Na+]sweat were greater at 60% exercise than at 40% exercise. In each individual, the [Na+]sweat increased significantly (P<0.05) with the increase in the SRch. In all subjects, the mean [Na+]sweat during exercise correlated negatively with the resting plasma ALD level at either percentage, but it did not correlate with the exercising ALD. These results suggest that individual variations in the increase of the [Na+]sweat in response to a rise in the SRch may thus be more closely related to the resting ALD than to the exercising ALD. As a result, the genomic action of ALD may be affected more by the sweat Na+ variation than by the rapidly non-genomic action during exercise in humans.
