Fig. 3. a) Results from the symbol substitution test at 0, 1, 2 and 3% dehydration levels at three environmental conditions; thermoneutral, hot-dry, and hot-humid. Mean levels of actual dehydration for only hot-dry and hot-humid conditions are shown in parentheses below the target levels. Actual dehydration levels for the thermoneutral condition were not reported. (*p < .05; this value has been computed from the original data as the authors did not test significance below the p < 0.01 level) Data re-plotted from Sharma et al. [13]. b) Results from the eye-hand coordination test at 0, 1, 2 and 3% dehydration levels at three environmental conditions -thermoneutral, hot-dry, and hot-humid. Mean levels of actual dehydration for hot dry and hot humid conditions are shown in parentheses below the target levels. Levels for the thermoneutral condition were not reported. (**p < 0.01; ***p < 0.001) Data re-plotted from Sharma et al. [13].
