value was 110.8 (19.1-186.2) ml/kg and the elevation from the average EPOC value of 20-25
min into the test was statistically highly significant (p< 0.01). The average values and ranges
for the heart rate and EPOC are presented in Table 1.
The average Tsk at the beginning of the test was 34.8 (33.8-35.5)°C, and during the
termination it was 36.4 (35.5-37.1)°C (Table 1). The elevation was statistically highly
significant (p< 0.01). At the beginning of the test the Tre varied from 36.8-37.5°C and the
end-of-exercise values varied from 37.5-38.7°C (Table 1 and Figure 1). The change in Tre was
highly significant (p< 0.01). Even those three subjects who completed the full 60 min HST
did not reach the ethically imposed Tre limit of 39.5°C. During the HST mean change in ∆S,
calculated for tolerated heat exposure time, was 48.6 (32.6-72.0) Wm -2 .
