Brief Summary

While long considered independently, energy expenditure and energy intake have been shown to interact. Fot the last 20 years, the litterature has been describing tyhe effects of an acute bout of exercise on subsequent energy intake and appetitive responses, indicating a potenital anorexigenic effect of intensive exercise in adolescents with obesity. These studies suggest a decrease in hunger, redcued satiety and modified food reward responses.

These results remain however obtained in studies using post exercise ad libitum test meals and this nature of the meal might ahve impact these responses.

The present work tends to assess the effect of acute exercise on subsequent appetite and food reward responses to a fixed meal, in adolescents with obesity.

Detailed Description

After an inclusion visit to ensure the aptitude of adolescents to complete the entire study, each will have to carry out densitometric measurements (body composition and bone structure). The adolescents will then carry out, in a randomized manner, 2 experimental sessions spaced at least 7 days apart: i) a control session (CON); ii) a session with a pedaling exercise at 65% of their estimated maximum capacity (EX).

During each of these experimental sessions, teenagers will receive a calibrated breakfast at 08:00 am. During the CON session, teenagers should not perform any physical activity during the day and they will be asked to stay at 11 a.m., for 30 minutes, resting in a semi-supine position. During the EX session, teenagers will perform moderate-intensity physical exercise (65% of their estimated maximum capacity) at 11 a.m. At noon, the teenagers will have to consume a calibrated meal. Questionnaires on feelings of hunger will be distributed to them at regular intervals. They will also be asked to complete a 10-minute computer exercise to assess their relationship to food just before and just after the calibrated midday meal (LFPQ. Leeds Food Preference Questionnaire, Liking/Wanting, French version). Sixty minutes after the calibrated meal, teenagers will have an ad libitum buffet available for one hour.
