The Effects of Substrate Oxidation on Post-exercise Food Intake in Pre-pubertal, Normal-weight Boys and Men
Year: 2013
Type: dissertation
Study design: Clinical Trial
Abstract: The relationship between substrate oxidation (RER) and food intake (FI) is undefined. This study examined the effects of RER modified by a glucose pre-load (GL), exercise (EX) and GL with EX on, FI and energy balance (NEB) in normal-weight boys (9-12 y) and men (20-30 y). Subjects (15 boys, 15 men) were randomized with treatments of either water or GL followed by either EX or rest. Measures included RER, energy expenditure (EE)(kcal/kg), subjective appetite, FI(kcal/kg) measured at a pizza lunch and NEB (kcal/kg). FI(kcal/kg) was reduced by GL(p < 0.0001), and further decreased with GL ingested prior to EX(p = 0.0254). RER was increased with GL(p < 0.0001) and EX(p = 0.0043), and was higher in men compared to boys (p = 0.007). There was no association between RER and FI(kcal/kg). In conclusion, there was no relationship between RER and FI, suggesting that FI is not affected by substrate oxidation.
