About this study

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.

Treatment and study plan

CON . control condition without exercise / rest condition

Other

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

Other

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-180. condition with an acute exercise set 180 minutes before lunch

Other

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.

Primary outcomes

  1. Energy intake measured during an ad libitum buffet meal (in kcal).

    Time frame: 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 (Casio Scale, units: grams) by a member of the investigation team and then analysed using Bilnuts software.

Secondary outcomes

  1. Hunger feelings

    Time frame: at day 1

    hunger area under the curve will be assessed using visual analogue scale (VAS) through a the day ranging from 0 to 150, 0 being "not at all", 150 being "completely". The question asked being: How hungry are you right now?"

  2. Food reward

    Time frame: at day 1

    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.To measure the explicit liking and explicit wanting, participants are asked to rate the extent to which they "liked" or "wanted" each randomly presented food item with a 100-mm visual analogue scale. . The construct from the scales are : Explicit liking; Explicit Wanting; Implicit liking, implicit wanting, Fat Choice and Fat Taste. Each component ranged from -50 to +50. There is no total score.
