While the beneficial effects of exercise on appetite might depend on its timing during the day or relative to a meal, this remains poorly explored in youth.
To examine the importance of meal timing (+30 vs +90 minutes) after performing exercise on energy intake, appetite and food reward in adolescents with obesity.
Eighteen adolescents with obesity randomly completed three conditions: (a) lunch (12:00 pm) set 30 minutes after a rest session (11:00 am); (b) lunch (12:00 pm) set 30 minutes after an exercise session (11:00 am)(MEAL-30); (c) lunch (01:00 pm) set 90 minutes after an exercise session (11:00 am)(MEAL-90). Lunch and dinner ad libitum energy intake was assessed, food reward (LFPQ) assessed before and after lunch, and before dinner, appetite sensations were assessed at regular intervals.
Energy intake was lower at MEAL-90 than MEAL-30 and CON at lunch (P < .05 and P < .01, respectively) and lunch + dinner combined (P < .001). A decrease in intake (g) of protein, fat and carbohydrate was observed. Post-exercise hunger was lower on MEAL-90 compared with CON. No condition effects were found at lunch for food reward.
Delaying the timing of the meal after exercise might help affect energy balance by decreasing ad libitum energy intake without increasing hunger and by improving satiety in adolescents with obesity.
运动对食欲的有益影响可能取决于其在一天中的时间或相对于进餐的时间，但这在年轻人中仍未得到充分探索。
研究运动后进食时间（+30 分钟与+90 分钟）对肥胖青少年能量摄入、食欲和食物奖励的重要性。
18 名肥胖青少年随机完成三种条件：（a）午餐（12:00 pm）在休息（11:00 am）后 30 分钟进行；（b）午餐（12:00 pm）在运动（11:00 am）后 30 分钟进行（MEAL-30）；（c）午餐（01:00 pm）在运动后 90 分钟进行（11:00 am）（MEAL-90）。评估午餐和晚餐随意能量摄入，午餐前后和晚餐前评估食物奖励（LFPQ），并定期评估食欲。
MEAL-90 的午餐能量摄入低于 MEAL-30 和 CON（分别为 P <.05 和 P <.01），午餐+晚餐的总能量摄入也低于 CON（P <.001）。观察到蛋白质、脂肪和碳水化合物的摄入量减少。MEAL-90 组运动后饥饿感低于 CON。午餐时，食物奖励无条件效应。
延迟运动后进食时间可能有助于通过减少随意能量摄入而不增加饥饿感，并通过提高肥胖青少年的饱腹感来影响能量平衡。
