We compared HL and change in body heat storage (S) during intermittent exercise in warm\/dry and warm\/humid conditions among older male firefighters (OLDER, n = 9, age = 54.7 \u00b1 2.1 yr), older (age-matched) nonfirefighters (NON-FF, n = 9, age = 52.8 \u00b1 1.2 yr), and young firefighters (YOUNG, n = 6, age = 26.7 \u00b1 0.8 yr).<\/p>\n<p>Methods: We measured evaporative heat loss and dry heat exchange via the Snellen whole-body direct calorimeter while participants performed four 15-min bouts of cycling at 400 W of metabolic heat production separated by 15-min recovery periods in warm\/dry (35 \u00b0C, 20% relative humidity) and warm\/humid (35 \u00b0C, 60% relative humidity) conditions.<\/p>\n<p>Results: We found no differences (P &gt; 0.05) in HL or cumulative S (\u0394S) between OLDER and NON-FF in the warm\/dry (\u0394S: OLDER = 233 \u00b1 26 kJ, NON-FF = 270 \u00b1 29 kJ) or warm\/humid (\u0394S: OLDER = 548 \u00b1 24 kJ, NON-FF = 504 \u00b1 47 kJ) conditions. The OLDER and NON-FF had lower HL than the YOUNG during exercise in both environmental conditions (P &lt; 0.05). The OLDER stored 40% (P &gt; 0.05) and 46% (P = 0.004) more heat than YOUNG in the warm\/dry and warm\/humid conditions, respectively. The NON-FF stored 63% (P = 0.016) and 34% (P = 0.025) more heat than the YOUNG in the dry and humid conditions, respectively.<\/p>\n<p>Conclusions: Older firefighters and age-matched nonfirefighters demonstrate similar HL and S during work in the heat. Moreover, HL is significantly reduced in older compared to younger firefighters during exercise in both warm\/dry and warm\/humid conditions. Consequently, older firefighters may be more susceptible to thermal injury while on duty than their younger counterparts.<\/p>\n<p><span style=\"color: #000000;\"><strong>Full Text Link: <\/strong><\/span><\/p>\n<p><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/25290744\/\" target=\"_blank\" rel=\"noopener noreferrer\">https:\/\/pubmed.ncbi.nlm.nih.gov\/25290744\/<\/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>Kenny GP, Larose J, Wright-Beatty HE, Boulay P, Sigal RJ, Flouris AD.
