ALT A, All participants completed four trials in differing WBGT. B, Mean ± SD change in core (rectal) temperature (ΔT c) from baseline for these 50 participants during 30-min rest and 180-min treadmill walking at a moderate metabolic rate of ~200 W·m−2 at 16°C, 24°C, 28°C, and 32°C WBGT. The numbers above and below each symbol denote the remaining number of participants after termination. Our analysis involved (i) comparisons across groups and conditions at the last common time point (60 min: indicated by the solid vertical line), (ii) comparing the proportion (percentage) of individuals who demonstrated a sustained ΔT c exceeding recommended limits (>1°C; dashed horizontal line) across groups in conditions under the ALV (i.e., 16°C and 24°C WBGT), and (iii) comparing the duration (min) of work completed before ΔT c increased above recommended limits (>1°C) and termination (tolerance time) across groups when working above the ALV (28°C and 32°C WBGT).
