About

The aim of the present study is to compare the effect of an exercise performed 180 or 30 minutes before lunch on the energy intake of adolescents with obesity.

Full description

The present study will compare the nutritional response to the realisation of an acute exercise 180 or 30 minutes before an ad libitum buffet meal in adolescents with obesity. 18 adolescents with obesity will be asked to randomly complete three experimental sessions: i) one control session (rest); ii) one session with an acute exercise realized 180 minutes before lunch; iii) one session with the same exercise performed 30 minutes before lunch. Their ad libitum energy intake will be assessed during lunch as well as at dinner time. Appetite feelings will be assessed at regular intervals and their food reward in response to the lunch will also be assessed.
