Factors which alter human physiological responses during exercise-heat acclimation

Support for international conference on physiological and cognitive performance in extreme environments

“…These findings were later supported, since there was concern over the generation of false positive results using this approach [7]. Others have used sweat rate as the index of physiological strain [28,29]. The former indicated that T rec was not a reliable measure of body temperature due to its slow dynamics and based their prediction on the inverse relationship between sweating and skin temperature.…”

“…Hence there was no consideration for acclimatization status or its applicability in other scenarios. Pandolf, Sawka et aL [29] found HR and T rec correlations with total sweat rate, onset of dripping, and ratio of forearm blood flow to dripping sweat rate and hence concluded that the level of thermal strain while exercising in the heat may be determined by skin blood flow and sweating. However they failed to control for relative work load (%V0 2m ax) in subjects under test.…”
