Abstract:<\/strong><\/span><\/p>\n

Aging exacerbates hyperthermia and cardiovascular strain during passive heat exposure, but it remains unclear whether those effects worsen in older adults with type 2 diabetes (T2D). We examined these responses in unacclimatized, physically active, older individuals with (n = 13, mean \u00b1 SD age: 60 \u00b1 8 years, HbA1c: 7.0 \u00b1 1.0%) and without (Control, n = 30, 62 \u00b1 6 years) well-controlled T2D during a brief, 3-h passive exposure to extreme heat (44\u00b0C, 30% relative humidity). Metabolic heat production, dry heat gain, total heat gain (metabolic heat production + dry heat gain), evaporative heat loss, body heat storage (summation of heat gain\/loss), rectal and mean skin temperatures as well as heart rate were measured continuously.<\/p>\n

No between-group differences were observed for metabolic heat production (T2D vs. Control; 53 \u00b1 5 vs. 55 \u00b1 7 W\/m2), dry heat gain (48 \u00b1 9 vs. 47 \u00b1 11 W\/m2), total heat gain (101 \u00b1 10 vs. 102 \u00b1 14 W\/m2) and evaporative heat loss (83 \u00b1 10 vs. 85 \u00b1 12 W\/m2) over the 3 h (all P > 0.05). Consequently, the changes in body heat storage (380 \u00b1 93 vs. 358 \u00b1 172 kJ, P = 0.67) were similar between groups. Moreover, no between-group differences in rectal and mean skin temperatures or heart rate were measured. We conclude that unacclimatized, physically active, older adults with well-controlled T2D do not experience greater hyperthermia and cardiovascular strain compared to their healthy counterparts while resting in extreme heat for a brief, 3-h period.<\/p>\n
