Abstract
The purpose of the present study was to compare the heat strain while waring nuclear, biological, and chemical (NBC) protective clothing following a hot-wet (HW) or hot-dry (HD) heat acclimation protocol. Twenty-two males were assigned to groups HW (n = 7), HD (n = 8), or control (C, n = 7). Subjects were evaluated during continuous treadmill walking while wearing lightweight combat clothing and during intermittent exercise while wearing the NBC protective clothing. Whle wearing Combat clothing, greater decreases in rectal temperature (Tre), mean skin temperature (Tsk), and heart rate were observed for both acclimation groups. For the NBC clothing trials, lower Tre, Tsk, and heart rates were observed only for group HW.
