Effects of HIIT and Plyometric Training on Muscle-tendon Structure, Function, and Metabolism in Children with Obesity at Different Maturation Stages (HIIT-PRO Kids)

What this Trial Is About

Researchers are investigating the effects of high-intensity interval training (HIIT) alone versus HIIT combined with plyometric training on muscle-tendon structure, function, and metabolism in children and adolescents with obesity. The study focuses on different biological maturation stages, specifically pre-age peak height velocity (pre-APHV) and post-APHV, to understand how maturation influences training adaptations. Pediatric obesity is a growing public health concern that affects muscle and physical function, and this trial aims to address these issues with targeted exercise interventions. Participants will be randomly assigned to one of four groups: HIIT plus plyometric training or HIIT alone, each for either pre-APHV or post-APHV obese children. Both interventions last twelve weeks with sessions three times per week. The HIIT plus plyometric group will start with two weeks of adaptation exercises followed by sessions including 15 minutes of HIIT and 5 minutes of jumping exercises. The HIIT-only group also starts with two weeks of adaptation followed by 20 minutes of HIIT per session. Intensity and recovery ratios progress over the twelve weeks, and exercise intensity, heart rate, and compliance are closely monitored. Before and after the twelve-week training, participants will undergo evaluations measuring Achilles tendon stiffness, muscle thickness, strength, oxygen consumption, metabolic profiles, body composition, and physical performance. Researchers will also assess quality of life, physical activity levels, and enjoyment. These assessments help determine the effects of the training on muscle-tendon properties, metabolism, and overall health in children with obesity. The total study duration for each participant includes baseline assessment, intervention, and post-intervention evaluation.
