Aerobic exercise plays an important role in prevention of obesity, improvement of sleep quality and cardiovascular function. The purpose of this study was to investigate the effects of 8 weeks of moderate-intensity aerobic exercise training on sleep quality, and also cardiac structure and function in inactive obese girls.

In this study, 20 inactive obese girls (mean age; 18 year, mean BMI ≥ 30 kg/m2) participated voluntarily and were randomly assigned to exercise (E, n=10) and control (C, n=10) groups. Exercise group participated in aerobic exercise program for 8 weeks (60 min/day, 3 times/week, 50%-70% maximal heart rate). Control group maintained their daily routine physical activity for 8 weeks. At baseline and after 8 weeks of the training program, both groups were evaluated for cardiac function and structure, and also sleep quality by use of echocardiography and sleep quality questionnaire respectively. T-test and Pearson correlation coefficient were used for data analysis. p≤0.05 was considered significant.

Sleep quality improved significantly in the exercise group compared to that in the control group (p ≤ 0/05). Among cardiac structural and functional indices, only cardiac output significantly increased in exercise group compared to that in the control group (p ≤ 0/05).

8 weeks of moderate intensity aerobic exercise training improved sleep quality in inactive obese girls. However, except for cardiac output, it did not create any significant change in other cardiac structural and functional indices.

The childhood obesity is associated with the development of type 2 diabetes and cardiovascular disease throughout the lifecycle. The purpose of this study was to examine the relationship between adiponectin, leptin, cholesterol and triglyceride serum levels in the overweight girls after 12 weeks moderate intensity aerobic exercise training.
This research was conducted with a semi- experimental methodology with pre-test and post-test. Nineteen overweight girls (aged 9.8±1.5 years) after getting consent volunteered for this study. Subjects performed moderate intensity aerobic exercise training for 12 weeks. Blood samples were collected after overnight fasting, before and after 12 weeks of exercise training program. Total cholesterol and triglyceride levels were assessed using an enzymatic colorimetric assay (GPO-PAP). Serum leptin and adiponectin levels were determined by enzyme linked immunosorbent assay (ELISA). Data analysis was performed by paired sample t-test, Pearson correlation coefficient, regression analysis and a significant level of p Body fat percentage, circulating levels of triglyceride and leptin of participants as compared to baseline after 12 weeks of aerobic exercise decreased and adiponectin significantly increased (p Moderate intensity aerobic exercise training caused favorable changes in body fat percentage and obesity-related metabolic biomarkers in prepubertal overweight girls.
