PARTICIPATING IN PHYSICAL ACTIVITY AFTER CONSUMING MEALS OF DIFFERING CALORIC CONTENT DOES NOT ALTER APPETITE FOUR HOURS POST ACTIVITY

Background: Caloric consumption combined with exercise may decrease subsequent appetite in adults, however this phenomenon has not yet been studied in children.Purpose: To assess children’s appetite after eating a low-calorie meal (LC) and participating in physical activity versus eating a high-calorie meal (HC) and participating in physical activity.Methods: Children (N=19, 6-10 years old) participated in two trials. The first trial consisted of consuming a HC or LC meal at lunchtime then playing in a gymnasium for thirty minutes. In the gymnasium, children had free-choice access to physical and sedentary activities and total activity was monitored via an accelerometer. The second trial was identical to the first except the participant consumed the opposite meal. Order of the meal condition was randomized. The two meal conditions consisted of the same foods, and equivalent macronutrient distribution, however children consumed 55% less energy in the LC (291.8 ± 12.1 kcals) compared to HC (659.5 ± 101.3 kcals). Before the meal, immediately after the meal, immediately after the 30-minute activity session and four hours after the meal, the following satiety domains were assessed via visual analogue scales: prospective food consumption, hunger and fullness. A total appetite score was then calculated from these domains. Appetite Score = Hunger + Prospective Consumption + (100 – fullness)Results: Physical activity during the HC (2176 ± 884 counts·min-1) and LC (1977 ± 1013 counts·min-1) conditions was not different (p = 0.4). ANOVA revealed a significant (p = 0.045) meal condition (HC, LC) by time (pre-, immediately post-meal, post-activity, four hours post-meal) interaction for appetite. Relative to the HC condition, appetite was greater (p = 0.015) in the LC condition immediately post-meal (71 ± 74 HC, 131 ± 96 LC) and post-activity session (96 ± 66 HC, 160 ± 57 LC). There were no differences (p = 0.16) in appetite pre-meal (225 ± 63 HC, 222 ± 61 LC) or four hours post-meal (234 ± 69 HC, 259 ± 52 LC) between the two meal conditions. Conclusion: Eating a LC meal followed by a bout of exercise resulted in an appetite that is very similar to a HC meal followed by a bout of exercise by the time the child would be eating their next meal.
