Abstract
We evaluated the reliability of a newly developed wearable ear canal thermometer based on three different experiments, in which ear canal and rectal temperature (Tear and Trec, respectively) were simultaneously monitored. In Experiment 1, participants sat at 28 °C and 50% relative humidity (RH), during which fanning or 41 °C lower legs water immersion was conducted. In Experiment 2, participants conducted a 70-min treadmill exercise (4 km/h, 0.5% slope) at 35 °C and 50% RH with intermittent fanning. In Experiment 3, participants completed a 20 min treadmill exercise (6 km/h, 5% slope) at 35 °C and 65% RH. Bland-Altman analysis for Tear and Trec showed the difference of - 0.2-0.3 °C and the limit of agreement of the mean ± 0.3-0.6 °C. The intraclass correlation coefficient was 0.44-0.83. The results may suggest that the ear canal thermometer is useful to assess core body temperature in sports and/or labor fields.
期刊介绍：
The Journal of Physiological Sciences publishes peer-reviewed original papers, reviews, short communications, technical notes, and letters to the editor, based on the principles and theories of modern physiology and addressed to the international scientific community. All fields of physiology are covered, encompassing molecular, cellular and systems physiology. The emphasis is on human and vertebrate physiology, but comparative papers are also considered. The process of obtaining results must be ethically sound.
Fields covered:
Adaptation and environment
Autonomic nervous function
Biophysics
Cell sensors and signaling
Central nervous system and brain sciences
Endocrinology and metabolism
Excitable membranes and neural cell physiology
Exercise physiology
Gastrointestinal and kidney physiology
Heart and circulatory physiology
Molecular and cellular physiology
Muscle physiology
Physiome/systems biology
Respiration physiology
Senses.
