ABSTRACT: The purpose of this study was to identify the effects of superficial cooling on thermoregulatory responses while exercising in a hot, humid environment while wearing an American football uniform. Nine male and female subjects wore a superficial cooling garment while in a cooling (CS) experimental condition or a no cooling (NCS) control condition during an exercise task consisting of: warm-up (WU), exercise (EX), and recovery (R). The exercise task simulated an American football conditioning session with subjects wearing a full American football uniform and performing anaerobic and aerobic exercises in a hot, humid environment. Subjects were allowed to drink water ad libitum during rest breaks. During the WU, EX and R periods, core body temperature (Tc) was measured to assess the effect of the cooling garment. Neither baseline resting (pre-warm-up) Tc nor post- warm-up Tc were significantly different between trials. We found no significant differences in exercise Tc between conditions. Time to return to baseline Tc revealed no significant differences between the experimental and control conditions. We found that the volume of fluid consumed was 34% less in the experimental (711.1 +188.0 mL) condition compared to the control (1077.8 +204.8 mL) condition. Our findings indicate the cooling garment was not effective in blunting the rise in Tc during warm up, attenuating a rise in Tc during intermittent exercise, nor in increasing a return to baseline Tc during a resting recovery period in a hot, humid environment while wearing an American football uniform.
