The effect of short duration exercise (EXR) on food intake (FI) and energy balance (EB) is not well understood in either normal weight (NW) or overweight (OW) and obese (OB) 9-14 years old children. Our purpose was to describe the effects of activity and a glucose drink on short term FI, appetite, and EB in NW, OW, and OB boys. Each boy received in random order either a noncaloric Sucralose sweetened control or glucose (1.0 g·kg(-1) body weight) drink 5 min after either exercise (EXR) or sedentary (SED) activity. Boys exercised for 15 min at their ventilation threshold (V(T)) in experiment 1 or at 25% above their V(T) in experiment 2. FI was measured at an ad libitum pizza meal 30 min after drink consumption. FI was lower after the glucose drink (p < 0.001) but not affected by activity, even though EXR increased appetite (p < 0.001). OW/OB boys ate more total food than NW boys (p = 0.020). EB over the duration of the experiments was reduced by EXR in OW/OB boys (p = 0.013) but not in NW boys in either experiment (p > 0.05). We conclude that intake regulation in OW/OB boys in response to a glucose drink is similar to NW boys, but it may be less responsive to activity.
