초록

This study examines the association between peripheral skin temperature and rectal temperature or thermal sensation during rest and exercise in transient cool and hot environments. Two experimental conditions with differing air temperature transients (20 o C and 30 o C) were compared: Condition 1 (20 o C rest, 30 o C rest, 30 o C exercise, 30 o C recovery, 20 o C rest, and 25 o C rest and lunch); Condition 2 (30 o C rest, 20 o C rest, 20 o C exercise, 20 o C recovery, 30 o C rest, and 25 o C rest and lunch). The rectal and wrist temperatures were monitored for six hours, along with heart rate and subjective responses from eight male subjects. The following results were obtained after analysis: (1) The wrist temperature was unrelated to the rectal temperature, but showed significant association with overall thermal sensation (P<0.01). Higher wrist temperature indicates a warmer sensation. (2) During exercise, the rectal temperature was affected by the air temperature to which subjects were exposed prior to the exercise, rather than the air temperature during the exercise. (3) Wrist temperature during exercise was decreased under both experimental conditions, but increased during recovery, irrespective of the air temperatures. (4) Wrist skin blood flow and heart rate showed no differences between the two experimental conditions. (5) Rectal temperature was significantly related to body mass index (BMI), but not total body fat. Taken together, these results indicate that during summer, wrist skin temperature reflects the overall thermal sensation and not the core body temperature during exercise and rest in indoor and outdoor environments.
