The purpose of the present study was to examine the extent of the variations in mean skin temperatures by Hardy and DuBois'7-point formula when different single trunk sites were assigned (Mean Tsk-chest, Mean Tsk-abdomen, and Mean Tsk-upper back for the chest, abdomen and back. respectively). The average of the three trunk sites (Mean Tsk-aii)was considered as a reference value. Eight male subjects underwent twelve experimental conditions: activities (rest and exercise)x clothing (Control, Tyvek and Vinyl condition)x air temperatures (25℃ and 32℃). The results showed that 1)for rest conditions, there was no difference among Mean Tsk-chest, T Tsk-upper back,and Tsk-all; 2)for exercising conditions at 25℃, Mean T61.kk tended to be greater than Mean Tsk-chest,and Tsk-abdomen. The differences were statistically significant f)r Control and Tyvek conditions (p<0.05); 3)for Control during exercise, Mean Tsk-abdomen was significantly lower than Mean Tsk-upper bacd,(P<0.05);4)Mean Tsk-all were not statistically distinguished from) Mean Tsk-chest,Tsk-abdomen,and Tsk-uper back. For estimating the Mean Tsk of lightly clothed male subjects during exercise using Hardy and DuBois' 7-pomt formula, reliance on the abdomen or the upper back as a site representative of the trunk is not recommended. A preferred single site during exercise was the chest for male subjects.
