The aim of this study is to examine the effect of 4 weeks of low intensity physical activity program on thyroid hormone levels in obese and overweight boys. A total of 27 boys in the 12-14 age range; obese group 12 and overweight group 15 were divided into two groups. Children who participated in the study during the 4 weeks 3 days a week, games and sporting selected time period of 60 minutes a day walking program applied increasingly. TSH, T3 and T4 levels were determined in blood samples taken at rest 1 day before and one day after the 4 week training program. In the statistical analysis of the data obtained in the study, SPSS package program SPSS 22.0 statistical program (SPSS Inc., Chicago, Illinois, ABD) was used. Paired Samples T tests were used to analyze the difference between the Independent Samples T and the pre-test and post-test of the groups in the comparison of the binary groups. At the end of the study, body weight and T3 values of obese subjects (n = 12) and body weight, BMI and T3 values of overweight group were found to be significantly different between pre-test and post-test (p <0.05). In the analysis of pre-test and post-test differences of measured characteristics of obese and overweight subjects, no significant difference was found (p>0,05). As a result; of obese and overweight boys in the 12-14 age range in the 4-week low intensity physical activity program it can be said to cause changes in thyroid hormone levels.

Background: Exercise leads to changes in hormonal concentration and metabolites which impacts growth and development; during physical activity, energy metabolism is influenced by hormones associated with pubertal development, and characterization of its response to exercise is essential. Therefore, we aimed to identify the effects of exercise on thyroid hormones in children and adolescents with thyroid function disorders. Methods: A comprehensive literature search was performed in PubMed, Scopus, Web of Science, CINAHL, and Embase based on the search strategy, and the articles were screened based on inclusion criteria, for which two independent reviewers conducted data extraction. The eligible studies were methodologically assessed using a modified Downs and Black’s checklist. The extracted data were summarized according to study population, intervention, type and duration, outcome measures, and results. Results: The total number of screened articles was 1,710, out of which six pape...

Thyroid hormonal status among children with obesity2015 •
It is presumed that free T4 and thyroid-stimulating hormone (TSH) levels are related to obesity, but the findings are inconsistent. In this study we evaluated T4 and TSH concentrations between normal children and those with obesity and possible correlations between body mass index (BMI) and these markers. In this prospective study, 190 children who were overweight and obese and 133 children without obesity of the same age and sex were evaluated. Thyroid function tests (TSH, total T4, free T4 and free T3) were measured in all subjects in both groups. Thyroid antibodies (thyroid peroxidase and thyroglobulin) were determined among those with elevated TSH levels. Levels of TSH and total T4 were significantly higher in children with obesity compared with the control group. Subclinical hypothyroidism was significantly higher in children with obesity (14.7%) compared with normal subjects (6.8%, p = 0.02). Among children with obesity and increased TSH levels, 10.7% had positive thyroid pero...

Thyroid hormones play multiple physiological effects essential for the maintenance of basal metabolic rate (BMR), adaptive thermogenesis, fat metabolism, and appetite. The links between obesity and the hormones of the thyroid axis, i.e., triiodothyronine (T3), thyroxine (T4), thyrotropin-releasing hormone (TRH), and thyrotropin (TSH), are still controversial, especially when considering children and adolescents. This population has high rates of overweight and obesity and several treatment approaches, including nutritional, psychological, and physical exercise interventions have been used. Understanding the importance of the hormones of the thyroid axis in the recovery from overweight and obesity may help directing measures to the maintenance of a healthy body composition. The present scoping review was carried out to analyze studies evaluating these hormonal levels throughout interventions directed at treating overweight and obesity in children and adolescents. The main purpose was...

Thyroid axis hormones and anthropometric recovery of children/adolescents with overweight/obesity: A scoping reviewIntroductionThyroid hormones exert multiple physiological effects essential to the maintenance of basal metabolic rate (BMR), adaptive thermogenesis, fat metabolism, growth, and appetite.

A correlation between thyroid hormone profile and physical parameters in normal personIntroduction: The aim of the study was to correlate the thyroid hormone profile with the age, height, weight, body mass index (BMI), with body fat percentage (BF%) in apparently healthy person. Materials and Method: 84 normal subjects were included in the present study. In thyroid hormone profile S. TSH, Total S. T3, and Total S. T4 were estimated by lumax chemiluminescence immunoassay strip reader in the laboratory. Height, weight and BMI were recorded by standard method and BF% was calculated by the formula. Analysis was done by SPSS software.
