چکیده:
Background and Purpose: Overweight and obesity in childhood are associated with the potential risk of cardiovascular disease and metabolic syndrome in adulthood. The purpose of this study was to investigate the effect of 12 weeks of moderate endurance training on lipid profile and body composition of overweight girls. Material and Method: The present study was semi-experimental with pre-test and post-test design, in which 19 overweight girls aged 8 to 12 were randomly selected. Before and after intervention, body composition of subjects was measured under fasting conditions by BODY LOGIC BODY FAT ANALYZER and biochemical indices were measured and recorded by enzyme-calorimetric method. Results: Statistical analysis showed that 12 weeks of endurance training resulted in a significant reduction in triglycerides levels (pConclusions: The findings of this study suggested that moderate intensity endurance training lead to improvement of body composition and biochemical parameters related to obesity in overweight girls, which reflected the vital role of these training in preventing obesity and related cardiovascular diseases among children and adolescents.
پیش زمینه: اضافه وزن و چاقی در دوران کودکی با خطر بالقوه بیماری های قلبی عروقی و سندروم متابولیک در بزرگسالی همراه است. هدف از مطالعه حاضر بررسی تاثیر 12 هفته تمرین استقامتی با شدت متوسط بر پروفایل لیپیدی و ترکیب بدنی دختران دارای اضافه وزن بود. روش شناسی: مطالعه حاضر از نوع نیمه تجربی و با طرح پیش آزمون و پس آزمون بود که در آن 19 دختر دارای اضافه وزن با رده ی سنی 8 تا 12 به صورت تصادفی انتخاب شدند. ترکیب بدنی آزمودنی ها در شرایط ناشتایی توسط دستگاه Body logic Body Fat Analyzer و شاخص های بیوشیمیایی به روش آنزیمی-کالرمتری پیش و پس از مداخله ی تمرینی اندازه گیری و ثبت شدند. یافته ها: تجزیه تحلیل آماری نشان داد، 12 هفته تمرین استقامتی منجر به کاهش معنی دار تری گلیسرید(025/ 0>p) و درصد چربی بدنی (002/ 0>p) شد، در حالی که تغییرات معنی داری در سطوح سرمی کلسترول و شاخص توده بدنی مشاهده نشد. نتیجه گیری: یافته های پژوهش حاضر نشان می دهد که تمرینات استقامتی با شدت متوسط منجر به بهبود ترکیب بدن و شاخص های بیوشیمیایی مرتبط با چاقی در دختران دارای اضافه وزن می شود که بیانگر نقش حیاتی اینگونه تمرینات در پیشگیری از چاقی و بیماری های قلبی عروقی مرتبط با آن در کودکان و نوجوانان می باشد.

Recent research suggests that body fat percentage is a more appropriate indices than body weight to detect unfavorable lipid profiles in children and adolescents (Oliosa, Zaniqueli, Alvim, Barbosa, & Mill, 2019).
However, few studies have examined physiological needs of children and to the best of my knowledge, there has been no study to evaluate body fat percentage, BMI and lipid profile changes follwoing endurance exercise training among iranian girls aged 8-12 years.

On the other hand, the results of this study showed that there was a significant reduction in body fat percentage and no significant changes in body mass index after 12 weeks of moderate-intensity endurance training, suggesting the benefits of such exercise training in improving the body composition of overweight children.
