Body temperature regulation in rats during exercise of various intensities at different ambient temperatures.

Abstract: We examined the relationship between body temperature, tail vasomotor response, and work intensity at different ambient temperatures in rats, using a treadmill and continuously measuring oxygen uptake during exercise. At an ambient temperature (Ta) of 24°C, rectal temperature (Tre) at the beginning of tail vasodilation during exercise increased in proportion to work intensity. After tail vasodilation Tre remained steady, and at the end of 30 min exercise Tre level was proportional to work intensity. At Ta of 1… Show more

“…The dependence of hyperthermia level on exercise intensity was not observed for running mice (27), but it agrees with observations for exercising humans (28,29) and exercising rodents that had their abdominal or rectal temperature measured (25,30). That exercising mice present different physiological responses from other species was also reported in a recent investigation focusing on their running-induced ventilatory responses (31), which may lead ultimately to a distinctive pattern of evaporative heat loss from the respiratory tract.…”

“…This marked T brain increase was likely caused by animal handling (a stressful procedure required to insert the thermistor) and/or by the lower rate of heat loss compared with the rate of heat production generally observed at the beginning of exercise [cutaneous heat dissipation usually increases within 8 to 10 min of exercise under temperate conditions (15)]. Indeed, the former hypothesis helps to understand why the initial T brain increase was unspecific to the treadmill speeds studied, whereas the second hypothesis is supported by observations that a steady-state T core (rectal or abdominal) was only attained following the increase in tail skin temperature during low-intensity exercise (24,25). …”

“…The increase in body temperature during intensive physical activity is a common phenomenon in mammals (e.g., [12,22,23]). Aerobic heat production is a function of oxygen consumption; for each liter of oxygen, about 20 kJ of heat is produced [24].…”
