Sleep is bi-directionally linked to energy balance. This crossover study design will evaluate the acute effect of a moderate energy deficit (500 kcal) induced by diet, exercise, or mixed (-250 kcal by diet and 250 kcal by exercise) on sleep and the next morning's appetitive responses. The study sample comprises 24 healthy young adults. The experimental measurements will be conducted in a naturalistic, momentary manner and partly assessed by the participants. The participants will undergo a run-in period in order to stabilize their sleep schedules and provide them with training on the study protocol and measurements. Indirect calorimetry will be used to determine their resting metabolic rate and peak oxygen consumption (VO peak). Then, they will take part in a control session (CTL), followed by three energy deficit sessions in random order: a diet-induced energy deficit session (DED), an exercise-induced energy deficit session (EED), and a mixed energy deficit session (MED). All experimental sessions will be separated by a one-week washout. The participants' sleep will be monitored by ambulatory polysomnography, and the next morning's appetitive response will be evaluated via ad libitum food intake, appetite sensations, and food reward, measured by a food liking and wanting computerized test.
睡眠与能量平衡呈双向关联。本交叉研究设计将评估由饮食、运动或混合（饮食减少 250 卡路里，运动增加 250 卡路里）引起的适度能量不足（500 卡路里）对睡眠和次日早晨食欲反应的急性影响。研究样本包括 24 名健康的年轻成年人。实验测量将以自然的、瞬间的方式进行，并由部分参与者进行评估。参与者将经历一个适应期，以稳定他们的睡眠时间表，并为他们提供研究方案和测量的培训。间接热量测定法将用于确定静息代谢率和峰值耗氧量（VOpeak）。然后，他们将参加一个对照期（CTL），然后随机进行三次能量不足期：饮食引起的能量不足期（DED）、运动引起的能量不足期（EED）和混合能量不足期（MED）。所有实验期之间将间隔一周的洗脱期。参与者的睡眠将通过动态多导睡眠图进行监测，次日早晨的食欲反应将通过随意食物摄入、食欲感觉和食物奖励进行评估，通过喜欢和想要食物的计算机测试进行测量。
