AI summary: who the study is looking for

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for children and teenagers with obesity who are before or after their fastest growth spurt. It compares two exercise programs over twelve weeks.

Age
7 to 17 years
Sex
All sexes can join.
Disease stage
Obesity, with a body mass index z-score of 2 to 3.5 standard deviations (BMI-z) for age and sex. Growth stage: -1 to -3 APHV (before peak growth) or +1 to +3 APHV (after peak growth).
Earlier treatment
People who did supervised exercise in the past six months cannot join.

Main reasons for not taking part

  • Cognitive disabilities
  • A muscle or bone condition that prevents regular physical activity
  • Severe heart disease that makes physical activity unsafe
  • Supervised exercise in the past six months

Original description
The randomized controlled trial will compare the effects of a High-intensity interval training (HIIT) protocol versus a HIIT plus plyometric training in the muscle-tendon structure function and metabolism of the pediatric population with obesity at different biological maturational stages (pre-to-age peak velocity [APHV] and post-APHV). Both groups perform baseline evaluations of the main and secondary outcomes and receive the intervention for twelve weeks, three times per week. Once the interventions are completed, the participants undergo the same evaluations they performed at baseline.Read full original descriptionShow less

Effects of HIIT and Concurrent HITT/Plyometric Training on Muscle-tendon Structure, Function and Metabolism in Pediatric Population With Obesity at Different Biological Maturation States (HIIT-PRO Kids): A Study Protocol of Randomized Controlled Trial

The randomized controlled trial will compare the effects of a High-intensity interval training (HIIT) protocol versus a HIIT plus plyometric training in the muscle-tendon structure function and metabolism of the pediatric population with obesity at different biological maturational stages (pre-to-age peak velocity [APHV] and post-APHV). Both groups perform baseline evaluations of the main and secondary outcomes and receive the intervention for twelve weeks, three times per week. Once the interventions are completed, the participants undergo the same evaluations they performed at baseline.

Inclusion: Pediatric population with obesity determined by the body mass index by z-score (BMI-z) ≥ 2 standard deviations (SD) and ≤ 3.5 SD of the median for age and sex; Pediatric population with -1 to -3 APHV (pre-APHV) and +1 to +3 APHV (post-APHV).

Exclusion: Musculoskeletal condition that prevents regular physical activity; Severe heart diseases that contraindicate the practice of physical activity; Cognitive Disabilities; Individuals who perform supervised exercise in the past six months.
