Clinical Trial Summary

The management of body mass and energy balance requires a better understanding and mastery of the interactions between our daily activities, such as physical exercise, and the control of our food intake.

Over the past 15 years, many studies have focused on the potential effects of physical exercise on this satiety cascade and on subsequent food intake, in many populations. Thus, both in normal-weight subjects and in patients suffering from overweight and obesity, it has been shown that the performance of an acute exercise of moderate intensity promotes a transient anorectic effect, reducing feelings of hunger post -exercise, and can even induce a reduction in subsequent food intake. In healthy young adults, recent results show that high-intensity physical exercise can reduce feelings of hunger and increase the satietogenic effect of a meal compared to a control condition and low-intensity exercise. intensity. Nevertheless, it seems that the food reward (which refers to the notion of food reward) does not respond in the same way, the authors not observing any change in either liking or wanting, regardless of exercise intensity. Importantly, this literature uses ad libitum test meals, wishing to assess both satietogenic, hedonic and purely nutritional responses (assessing the amount of food intake). Nevertheless, these sensory and hedonic responses to food intake have recently been shown to be sensitive to the composition of the meal and its caloric quantity, which could induce a significant bias as to the conclusions on the effects of physical exercise. Indeed, the use of meals ad libitum, by definition, leads to caloric intake and different meal compositions. Thus, it is possible that the results obtained are strongly impacted by the nature of the test meal more than by the exercise itself. It therefore remains uncertain today to conclude as to the effects of physical exercise on the factors of the satietogenic cascade, since beyond physical exercise, the test meals compared are not identical. It therefore seems important today to develop a more coherent and adapted methodology, to better study the food and satietogenic responses to our daily activities.

In this context, the present project aims to compare the satietogenic response to a meal following acute exercise according to the nature of this meal (ad libitum versus calibrated) in healthy adults.

• Exercise

Intervention

Behavioral:
• Exercice and meal
The participants will carry out four experimental visits in a randomized order: CON_Calibré: control condition with a calibrated test meal; CON_AdLib: control condition with an ad libium test meal; EX_Calibré: exercise condition with a calibrated test meal; EX_AdLib: exercise condition with an ad libitm test meal. During each of the conditions, the participants will join the laboratory at 8:00 a.m. and will receive a calibrated breakfast. They will be asked at 11:00 a.m. either to rest in a semi-recumbent position for 30 minutes (CON conditions) or to perform a pedaling exercise on an ergocycle at 65% of their estimated aerobic capacity for 30 minutes. A test meal will be served to participants at 12:00 p.m., either ad libitum or calibrated. Appetite sensations will be assessed at regular intervals during each condition and their food reward preferences and ratio assessed 15 minutes before and 15 minutes after the test meals.
