Nutritional Responses to Acute Exercise Performed on the LipoxMax in Obese Adolescents
Sponsor: Centre Hospitalier Emile Roux
Summary
Primarily over the past 20 years, it has been shown that physical activity not only leads to energy expenditure but can also indirectly influence energy intake and feelings of hunger in both lean and obese adults, suggesting that physical activity has a dual effect on energy balance. Studies in children and adolescents are less common, but it now seems clear that their energy intake is affected by physical exercise ) depending on their weight status.

Interventions
The participants in this study are adolescents with obesity (with a Body Mass Index above the 95th percentile on international growth charts)
This study aims to understand how physical exercise performed at a specific intensity that promotes fat utilization (called LipoxMax) influences food intake, hunger, and food preferences in adolescents with obesity. Following an initial screening visit to verify eligibility criteria and assess dietary habits, participants undergo a measurement visit at Clermont-Ferrand University Hospital, which includes anthropometric assessments (height, weight, waist and hip circumferences), body composition measurements (body fat, muscle mass, bone structure), and a bicycle ergometer test to determine their LipoxMax intensity. The adolescents then undergo two experimental visits at the AME2P laboratory in Clermont-Ferrand, conducted in random order and spaced at least five days apart. At each visit, they arrive having fasted, consume a standardized breakfast, and then rest until 11:00 a.m. They then either rest for 40 minutes (control condition) or perform a 40-minute exercise session at LipoxMax.
