dc.description.resumoThis study aimed to evaluate the changes in brain (Tbrain) and abdominal (Tabd) temperatures in spontaneously hypertensive rats (SHRs) following fatiguing exercise. Male normotensive Wistar rats (NWRs) and SHRs were used at 16 weeks of age. Their arterial pressure was measured by tail plethysmography prior to the experiments to confirm the hypertensive status of the SHRs. Then, the rats underwent implantation of an abdominal temperature sensor to measure Tabd and a guide cannula in the frontal cortex to enable the insertion of a thermistor to measure Tbrain. After a familiarization period, each animal was subjected to incremental speed exercises until fatigue in either a temperate (25 °C) or warm (32 °C) environment, followed by a 60-min post-exercise period at the same temperature at which they exercised. Tbrain, Tabd and tail-skin temperature (Tskin) were measured every min throughout the experiments. SHRs exhibited higher Tabd values than NWRs, and these higher values were transiently and persistently observed at 25 °C and 32 °C, respectively. For example, at 32 °C, Tabd was 0.84 °C higher in SHRs at the 25th min (large effect size). In contrast, regardless of the ambient temperature, SHRs exhibited similar Tbrain values as NWRs, indicating preserved Tbrain regulation following exercise in hypertensive rats. SHRs presented higher Tskin during the last half of the post-exercise period at 25 °C, whereas no inter-group differences were observed at 32 °C. In conclusion, the present results highlight that SHRs, an animal model that mimics uncontrolled essential hypertension in humans, exhibited greater impairments in regulating Tabd than Tbrain during the post-exercise period.pt_BR
