TI  - Effect of body composition on metabolic responses to carbohydrate feeding in 
      males during exposure to 8, 12, and 27 degrees C.
PG  - 173-82
AB  - The effect of body composition on thermoregulation in response to a feeding 
      regime was evaluated in eight male volunteers (21-27 years of age) during 120 min 
      of exposure at 8, 12, and 27degrees C. Subjects were divided with respect to body 
      fat [high fat (HF) = 19-28%, N = 4: low fat (LF) = 10-15%, N= 4] and randomly 
      assigned the three air temperature conditions twice to examine the thermogenic 
      effect of a sequential timed feeding regime of either a carbohydrate (CHO) or 
      placebo (PL) beverage during exposure. Tissue insulation (I), rectal temperature 
      (T(re)), mean skin temperature (T(sk)), metabolism (M), and respiratory exchange 
      ratio (R) were examined. T(re), T(sk), M, and I revealed no significant 
      differences between treatment (PL vs. CHO) at any temperature (8, 12, or 27 
      degrees C). However, pooled T)(sk) at 27 degrees C, and pooled I at 12 degrees C 
      revealed significant (p < .05) differences between the LF and HF groups. In 
      addition, at 8, 12, and 27 degrees C, pooled T(re), T(sk), and I decreased (p < 
      .05) during the length of exposure, whereas pooled M increased (p < .05) at 8 and 
      12 degrees C. Pooled R increased during the length of exposure (p < .05) at 8 and 
      12 degrees C and differed (p < .05) between the LF and HF groups at 8 degrees C 
      only. From these data, it appears that whereas substrate utilization differed 
      between dietary treatment (8 degrees C) and across time (8 and 12 degrees C), 
      there was a differential effect between LF and HF groups (T(sk) at 27 degrees C 
      and I at 12 degrees C) that was not influenced by feeding regime.
