Abstract:

In order to further understand the temperature changes of different parts of the body and provide references for warm and cool keeping, 3 female volunteers participated in the experiment first in the environment woth the temperature of 15℃ and the relative humidity of 50%. The temperatures of clothing surface were measured by an infrared thermal imager when they kept stationary and exercised after 10, 20 and 30min, respectively. Moreover, the body temperature distribution were divided. Then 13 participants were involved in the same experiments and gave their subjective thermal sensation assessments. By the analysis, body surface temperature changes regulation and subjective thermal sensation were obtained. Results show that cooling and permeability can be strengthened in the parts of scapula, chest, right elbow and left arm when the body is in exercising, and on the warm keeping can be attached importance in the parts of abdomen, lateral thorax and spine when the body is in stationary state.

Key words: body surface, exercise state, subjective thermal sensation assessment, surface temperature
