Endogenous Hormones Subtly Alter Women's Response to Heat Stress. (Reannouncement with New Availability Information).

摘要

The thermoregulatory responses of menstruating women to exercise in dry heat (dry-bulb temperature wet bulb temperature = 48/25 C) were evaluated at three times during the menstrual cycle: menstrual flow (MF), 3-5 days during midcycle including ovulation (OV), and in the middle of the luteal phase (LU). We conclude that (1) the menstrual cycle alters temperature regulation without obvious alterations in sweat output or steady state metabolic rate, (2) these changes are so subtle that they easily could be missed if hormonal status is not carefully monitored concomitant with HST, and (3) the magnitude of the changes are small and do not impair a woman's ability to work in dry heat.
