Correlated Thermophysiological Parameters of Human Body in the Moderate Thermal Environment at Sedentary Activity Level

Abstract

In this study, the correlation of human physiological parameters to ambient temperature was evaluated in the temperature range of 21–29 °C. The physiological parameters investigated herein included mean skin temperature (MST), heart rate, the ratio of absolute power in low frequency (LF) and high frequency (HF) bands (LF/HF ratio). The results of ANOVA and R test indicated that MST was correlated to ambient temperature, while LF/HF ratio was not found to be correlated at all. Heart rate was a little more correlate to low temperature than high temperature. The conclusions are significant to select suitable parameters for human thermal response research in the moderate thermal environment.
