humid conditions to identify which intervention
provided the greatest improvements in evaporative cooling and
thermal perceptions.
The combination of stepping exercise and heat stress used in
this study was sufficient to induce a light to moderate cardiovas-
cular and thermoregulatory challenge. During exercise, M/E
showed a greater increase in Tre and a lower skin temperature
compared to CON. The inverse relationship between skin and deep
body temperature in the M/E condition was most likely mediated
by menthol and ethanol (Gillis et al., 2010; Gillis et al., 2015). The
M/E condition contained 16.8 mg of menthol (0.2% of 80 mL), this
equated to 1.6 mg 100 cm2 of menthol spread over the upper
body.
