Aquatic exercise has been suggested as a beneficial modality to improve weight loss, cardiorespiratory fitness and quality of life in adolescents with obesity; however, its impact on appetite control in youth remains unknown. The aim of this preliminary study was to examine the effect of an acute aquatic exercise session on energy intake (EI), appetite feelings and food reward in adolescents with obesity. Twelve adolescents with obesity (12-16 years, Tanner stage 3-5, 9 males) randomly completed two conditions: i) control (CON); ii) aquatic exercise session (AQUA). One hour before lunch, the adolescents stayed at rest outside the water in a quiet room for 45 min on CON while they performed a 45-min aquatic exercise session on AQUA. Ad libitum EI and macronutrients were assessed at lunch and dinner, subjective appetite feelings taken at regular intervals, and food reward measured before and after lunch. Paired T-test showed that EI was not different between CON and AQUA at lunch (1333 ± 484 kcal vs 1409 ± 593 kcal; p = 0.162) and dinner (528 ± 218 kcal vs 513 ± 204 kcal; p = 0.206). Total daily ad libitum EI was significantly higher on AQUA (1922 ± 649 kcal) compared with CON (1861 ± 685 kcal; p = 0.044) but accounting for the exercise-induced energy expenditure, relative energy intake did not differ (2263 ± 732 kcal vs 2117 ± 744 kcal, p = 0.304). None of the appetite feelings (hunger, fullness, prospective food consumption and desire to eat) and food reward dimensions were significantly different between conditions. These preliminary and exploratory results suggest that an acute aquatic-exercise session might not induce energy compensatory responses in adolescents with obesity.
水上运动已被建议作为一种有益的方式，可以改善肥胖青少年的减肥、心肺健康和生活质量；然而，其对青少年食欲控制的影响尚不清楚。本初步研究旨在探讨急性水上运动对肥胖青少年能量摄入（EI）、食欲感觉和食物奖励的影响。12 名肥胖青少年（12-16 岁，Tanner 阶段 3-5，9 名男性）随机完成两种情况：i）对照（CON）；ii）水上运动（AQUA）。午餐前 1 小时，青少年在安静的房间外的水中休息 45 分钟，在 CON 时进行 45 分钟的水上运动，在 AQUA 时进行 45 分钟的水上运动。午餐和晚餐时评估随意性 EI 和宏量营养素，定期记录主观食欲感觉，午餐前后测量食物奖励。配对 T 检验显示，CON 和 AQUA 时午餐的 EI 没有差异（1333±484 千卡与 1409±593 千卡；p=0.162）和晚餐（528±218 千卡与 513±204 千卡；p=0.206）。与 CON（1861±685 千卡）相比，AQUA（1922±649 千卡）的总日随意 EI 明显更高（p=0.044），但考虑到运动引起的能量消耗，相对能量摄入没有差异（2263±732 千卡与 2117±744 千卡，p=0.304）。在条件之间，没有食欲感觉（饥饿、饱腹感、预期食物消耗和想吃的欲望）和食物奖励维度存在显著差异。这些初步和探索性的结果表明，急性水上运动可能不会引起肥胖青少年的能量补偿反应。
