Brief summary
The aim of the present study is to compare the effect of an exercise alone versus. An exercise followed by the ingestion of an energy replacement snack on the following energy intake, food reward and appetite feelings in adolescents with obesity.
Detailed description
The present study will compare the nutritional response to the realisation of an acute exercise with and without an energy replacement snack on the following energy intake 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 during the morning; iii) one session with the same exercise followed by a snack covering the exercise-induced energy expenditure. Their ad libitum energy intake will be assessed at the following meal 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.
Interventions
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.
BEHAVIORALEX. Condition with an acute exercise set in the middle of the morning
EX. Condition with an acute exercise set in the middle of the morning The adolescents will be asked to complete a 30 minutes exercise set at 65% of their capacities (cycling) in 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+R. condition with an acute exercise set in the morning and followed by a energy replacement snack The adolescents will be asked to complete a 30 minutes exercise set at 65% of their capacities (cycling) in the morning followed by a snack that will cover the whole exercise-induced energy expenditure. They will then 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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Energy intake measured during an ad libitum buffet meal (in kcal). | at lunch (at day 1) | food intake will be measured ad libitum during a lunch buffet. The adolescents will be offered an ad libitum buffet-type meal composed based on their food intake preferences. Their intake will be weighted using an electronic food scale by a member of the investigation team and then analysed using Bilnuts software |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Measurement of hunger feelings | at day 1 | hunger area under the curve will be assessed using visual analogue scale through a the day (Leeds Food Preference Questionnaire; LFPQ) Briefly, the LFPQ provides measures of the wanting and liking for an array of food images, varying in both fat content and taste |
| Food reward | at day 1 | The participants will be asked to complete a validated computer-based procedure to measure food reward (Leeds Food Preference Questionnaire; LFPQ) (Finlayson, King et al. 2008).Briefly, the LFPQ provides measures of the wanting and liking for an array of food images, varying in both fat content and taste |
