Effect of Adding Short Intense Exercise Sessions to Standard Care on Physical Fitness in Obese Adolescents Aged 11 to 18

What this Trial Is About

Researchers are investigating whether adding very short, intense exercise sessions called exercise-snacks to a traditional care program can improve physical fitness and health in obese adolescents. This study focuses on adolescents with obesity and sedentary lifestyles, aiming to reduce sedentary behavior and improve body composition, vascular function, and physical activity habits. Forty-eight obese adolescents will participate in this randomized study to evaluate the benefits of these exercise-snacks alongside standard care. Participants will be randomly assigned to one of two groups. The exercise-snack group will perform four brief, intense exercise sessions each day for three weeks in addition to receiving a multidimensional care program. These sessions last about one minute each and are supervised. The control group will receive only the standard care program without exercise-snacks. Both groups will receive education about physical activity attitudes. During the study, researchers will assess physical fitness, body composition, vascular health, eating behaviors, and levels of physical activity and sedentary behavior. Evaluations will take place at the start and end of the three-week program, and again at one and three months after the program ends. The main measure is change in aerobic fitness, with other outcomes including changes in fat mass, body mass index, carotid artery thickness and compliance, and questionnaires about physical activity and eating habits.
