Structured Exercise Prescription Program in Obese Children

Efficacy of a Structured Exercise Prescription Program Over Anthropometric, Metabolic and Fitness Parameters in Obese Children and Adolescents Included in a Multicomponent Lifestyle Intervention Program. Randomized Clinical Trial

National Council of Science and Technology, Mexico, Fundacion Sertull, Universidad Nacional Autonoma de Mexico

This controlled clinical trial aims to compare the effects of a multicomponent program that includes structured personalized exercise prescription in children with obesity with a control group that will be enrolled in a multicomponent program without structured personalized exercise prescription. All children will be followed for a period of 6 months. The parameters that will be evaluated between groups are physical fitness, anthropometry, metabolic (glucose oral tolerance curve, lipids, HOMA-IR, ISI-MATSUDA), early cardiovascular damage, inflammatory biomarkers, anxiety and depression scores, and allelic variants related to physical fitness.

This controlled clinical trial aims to compare the effects of a multicomponent program that includes structured personalized exercise prescription in children with obesity (study group) with a control group that will be enrolled in a multicomponent program without structured personalized exercise prescription. All children will be followed for a period of 6 months. The parameters that will be evaluated between groups are physical fitness (measured by VO2max, ECG at rest, biomechanics and dynamometry), anthropometric measurements (weight height, BMI, plicometry, bioimpedance, metabolic (glucose oral tolerance curve, lipids, HOMA-IR, ISI-MATSUDA), early cardiovascular damage (carotid intima-media thickness, atherogenic dyslipidemia), inflammatory biomarkers (leptin, adiponectin, IL-17, IL-10, INF-gamma, IL-6, IL-12, y TNF-alpha), anxiety and depression scores evaluated with Child Depression Inventory (CID) and -Trait Anxiety Inventory for Children (STAI-CH), and allelic variants related to physical fitness (ACTN, TRH2 y FTO).

This group will be enrolled in a multicomponent program for obese children (8-12 years old) that includes intervention workshops concerning nutrition, emotional factors, cognitive therapy and personalized structured exercise prescription that will be offered on-site and online and monitored through the use of heart rate monitoring devices. The type of exercise offered to patients in this arm is precisely designed for obese patients according to age and physical fitness parameters. Intervention: Non-personalized non-structured exercise

This group will be enrolled in a multicomponent program for obese children (8-12 years old) that includes intervention workshops concerning nutrition, emotional factors, cognitive therapy and non-personalized non-structured exercise prescription Intervention: Non-personalized non-structured exercise

The type of exercise offered to patients in this arm is precisely designed for obese patients according to age and physical fitness parameters. Patients are monitored using a heart rate monitor to evaluate treatment adherence and compliance

The type of exercise is non-structured and patients' heart rate is not monitored. Patients receive exercise recommendations without any personalization according to their fitness parameters

Inclusion Criteria: Patients with BMI ≥ Pc 95 and < 35kg/m2 Both sexes Accepts to participate and signs informed consent Exclusion Criteria: Presence of endocrine disease including type I and II diabetes mellitus Presence of arterial hypertension Presence of primary dyslipidemia Presence of infections at moment of enrollment Presence of systemic disease Presence of genetic disorder Medical treatment that may interfere with lipid or glucose metabolism Prolonged or acute immobilization Participated in a previous similar intervention
