Fifteen healthy adults (8 men; 7 women; 24.9 +\/- 4.6 years) volunteered.<\/p>\n<p>Following a 15 min baseline period, participants entered a water tank maintained at 42 degrees C water temperature and passively rested until their T(re) increased by 0.5 degrees C above baseline. Thereafter, they entered a different water tank maintained at 12 degrees C water temperature until their T(re) decreased by 0.5 degrees C below baseline. This procedure was repeated twice (i.e. A-B-A-B). T(ty) demonstrated moderate response delays to the repetitive changes in thermal balance, whereas T(X) and T(re) responded relatively fast. Both T(ty) and T(X) correlated significantly with T(re) (P &lt; 0.05). Linear regression models were used to predict T(re) based on T(ty) and T(X).<\/p>\n<p>The predicted values from both models correlated significantly with T(re) (P &lt; 0.05) and followed the changes in T(re) during the A-B-A-B thermal protocol. While some mean differences with T(re) were observed (P &lt; 0.05), the 95% limits of agreement were acceptable for both models. It is concluded that the calculated models based on tympanic and exhaled breath temperature are valid indicators of core temperature.<\/p>\n<p><span style=\"color: #000000;\"><strong>Full Text Link: <\/strong><\/span><\/p>\n<p><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/20348612\/\" target=\"_blank\" rel=\"noopener noreferrer\">https:\/\/pubmed.ncbi.nlm.nih.gov\/20348612\/<\/a><\/p>\n<p><img decoding=\"async\" class=\"alignnone wp-image-8302 size-full\" src=\"https:\/\/www.famelab.gr\/wp-content\/uploads\/2021\/11\/Line.png\" alt=\"\" width=\"1316\" height=\"1\" \/><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>","protected":false},"excerpt":{"rendered":"<p>Flouris AD, Cheung SS.
