Abstract

A study was conducted to assess the lifting capabilities of acclimatized individuals in hot environments. Six male subjects were selected for the study. The subjects were heat acclimatized for ten days prior to participation in the experiment. A psychophysical experiment was then carried out using three temperature levels (22, 27, and 32[deg]C Wet Bulb Globe Temperature (WBGT), three frequencies of lift (0.1, 3 and 6 lifts/min), and one height of lift (floor to knuckle height). The results indicated that the maximum acceptable weights of lift selected by the subjects at 27[deg]C WBGT were not significantly different from the weights selected at 22[deg]C WBGT. On the other hand, the maximum acceptable weights selected at 32[deg]C WBGT were reduced by approximately 13 percent.
