| Popis: | Due to its volatility, the qualitative experience of menthol may be modulated by its preparation and combination with other compounds. One such method of preparation is dilution, with two dilution methods existing within the sport and exercise science literature, where menthol is used to impart feelings of oral cooling and improve thermal comfort and sensation during heat exposure. This study compared these two dilution methods one using a solvent the other using temperature, via a randomized counterbalanced repeated measures design (n = 12 Height: 174.0 ± 8.5 cm Mass: 73.4 ± 13.3 kg Age: 28.7 ± 8.4 y two exposures to each solution) to assess the effect of solution and heat exposure, upon thermal comfort, thermal sensation and associated physiological parameters in non-heat acclimated participants. Thermal comfort was significantly affected by solution (p = 0.041 η2 = 0.017) and time (p < 0.001 η2 = 0.228), whereas thermal sensation was significantly affected by time only (p = 0.012 η2 = 0.133), as was tympanic temperature (p < η2 = 0.277). Small to moderate clear differences between solutions at matched time points were also observed. These trends and effects suggest that, depending upon the dilution method employed, the resultant perceptual effects are likely impacted this also likely depends upon the timing of menthol administration within a heat exposure session. |
