Obese adolescents
18 adolescents with obesity are involved and will perform the three conditions.
CON
. Control condition without exercise / rest condition. The adolescents will be asked to remain quiet and at rest during the morning and will receive an ad libitum meal at lunch and dinner times. Their food reward will be assessed before and after lunch. Their appetite feelings will be assessed at regular intervals.
EX-30
Condition with an acute exercise set 30 minutes before lunch The adolescents will be asked to complete a 30 minutes exercise set at 65% of their capacities (cycling), 30 minutes before lunch. Lunch will be served ad libitum as well as diner. Their food reward will be assessed before and after lunch. Their appetite feelings will be assessed at regular intervals.
EX-90
condition with an acute exercise set 90 minutes before lunch. The adolescents will be asked to complete a 30 minutes exercise set at 65% of their capacities (cycling), 30 minutes before lunch. Lunch will be served ad libitum as well as diner. Their food reward will be assessed before and after lunch. Their appetite feelings will be assessed at regular intervals.
