AB  - We examined the effects of consuming a 6% carbohydrate (CHO) beverage during 
      exercise on substrate oxidation in active, young Caucasian women with higher body 
      fat (HF) (>25%) and lower body fat (LF) (<25%). The HF group (n = 9) had 32.4% +/- 
      5.6% fat and the LF group (n = 8) had 20.0% +/- 3.0% fat. Subjects completed 2 
      sessions of 45 min of treadmill exercise at 55% of maximal oxygen consumption. 
      Immediately prior to and at 15-min intervals during exercise, subjects consumed 
      25% of a total volume of a CHO beverage (1 g CHO.kg(-1)) or a placebo (PLC). 
      During exercise and for 2 h after exercise, expired gases were analyzed to 
      determine oxidation rates for CHO (CHO-OX) and fat (FAT-OX). During exercise, 
      significant differences (p < 0.05) in CHO-OX (mg.kg fat-free mass(-1).min(-1)) 
      were found between groups for the CHO trial (LF, 35.4 +/- 4.7 vs. HF, 29.8 +/- 3.6) 
      and the PLC trial (LF, 33.7 +/- 6.4 vs. HF, 26.3 +/- 4.3). CHO-OX was significantly 
      higher during the first hour of recovery in both the LF group (CHO, 9.3 +/- 2.1 vs. 
      PLC, 5.3 +/- 2.4) and the HF group (CHO, 8.7 +/- 2.0 vs. PLC, 4.2 +/- 1.0), but during 
      the second hour of recovery, only the HF group had a higher CHO-OX (CHO, 5.3 +/- 
      1.8 vs. PLC, 3.9 +/- 1.1). FAT-OX was significantly lower during the first hour of 
      recovery in both the LF group (CHO, 0.6 +/- 0.4 vs. PLC, 1.0 +/- 0.4) and the HF 
      group (CHO, 0.4 +/- 0.4 vs. PLC, 1.4 +/- 0.4), as well as during the second hour of 
      recovery in both the LF group (CHO, 0.8 +/- 0.4 vs. PLC, 1.3 +/- 0.5) and the HF 
      group (CHO, 0.9 +/- 0.6 vs. PLC, 1.6 +/- 0). CHO ingestion promotes CHO-OX and 
      suppresses FAT-OX during and following exercise in physically active women with 
      low and high levels of body fat.
