Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Obese adolescents

18 adolescents with obesity are involved and will perform the three conditions

Group Type EXPERIMENTAL

CON . control condition without exercise / rest condition

Intervention Type BEHAVIORAL

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. Condition with an acute exercise set in the middle of the morning

Intervention Type BEHAVIORAL

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

Intervention Type BEHAVIORAL

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.
