Book synopsis

This work measured maximal oxygen uptake (VO2max) and§core temperature (TC) at exhaustion, and oxygen§uptake and heart rate during submaximal exercise in§22 runners under 7 conditions. The conditions were:§1) 25 degrees C (dC), no preheating; 2-4 and 6) 25,§35, 40, and 45 dC, with preheating by a 20-min walk;§5) 45 dC, no preheating; and 7) 45 dC, with passive§preheating raising TC to the same degree as at the§end of the 20-min walk in Condition 6. Compared to§the Condition 1, VO2max was reduced 3-9% under§Conditions 2-5 when TC at VO2max was below the§apparent critical TC, but was reduced 17-19% under§Conditions 6-7 when a critical TC appeared to have§been attained. Heart rate and relative metabolic§intensity (%VO2max) during submaximal exercise§increased in an identical fashion in the heat, and§the elevations in heart rate were significantly§related to the reductions in VO2max (r = 0.79). It§was concluded that large reductions in VO2max in§uncompensable heat stress are associated with§attainment of a critical TC. Elevation in heart rate§during submaximal exercise in the heat is§proportional to reduced VO2max, and not indicative of§dissociation between heart rate and %VO2max.
