简要总结
Acute exercise has been shown to affect subsequent energy intake in obese adolescents. Indeed, it has been shown several times that an intensive bout of exercise (above 70% of the individual maximal capacities) can reduce energy intake at the following meal in obese adolescents, with no modification of his appetite feelings.
Although this results has been replicated several times, it remains unknown if those nutritional adaptations are due to post-exercise modifications of some gastro-peptides implicated in appetite control, as detailed in adults.
The aim of this work is to question whether or not post-exercise energy intake is explained by appetite-regulating hormones that are affected by the exercise bout in both lean and obese youth.
详细描述
After an first medical visit to ensure that the adolescents have the ability to complete the whole study, the participants will have to complete several clinical examinations:
- anthropometric measurements
- Body composition assessed by dual energy x-ray absorptiometry
- Maximal aerobic test
They will then randomly complete the following conditions:
- CON: a control day without exercise;
- HIE: an exercise day with an exercise set at 75% of the capacities
- LIE: an exercise day with an exercise set at 40% of the capacities
The exercises or the rest condition will be done by the end of the morning and a buffet meal will be proposed during which the participants will be asked to eat as much as wanted.
