مقدمه : هدف از انجام این تحقیق بررسی اثر یک دوره سه ماهه تمرینات منتخب ورزشی بر ترکیب بدن ساختاری کودکان ۷ تا ۱۳ سال بود .روش شناسی تحقیق : جامعه آماری این تحقیق را دختران سن 7 تا 13 سال دارای اضافه وزن شهرستان مرودشت تشکیل می دادند که تعداد 20 نفر از آنها به صورت داوطلبانه در دسترس به عنوان نمونه آماری انتخاب شدند و به مدت سه ماه تمرینات منتخب را زیر نظر مربیان به مدت 2 جلسه 60 دقیقه ای در هفته انجام دادند. جهت بررسی داده های تحقیق از آمار توصیفی میانگین و انحراف استاندارد و آماراستنباطی t وایسته استفاده گردید. یافته ها : نتایج این تحقیق نشان داد: یک دوره سه ماهه تمرینات منتخب ورزشی بر تغییرات وزن کودکان ۷ تا ۱۳ سال اثر معنی داری دارد( 05/9- = t ، 001/0 = p ).یک دوره سه ماهه تمرینات منتخب ورزشی بر تغییرات شاخص توده بدن (BMI ) کودکان ۷ تا ۱۳ سال اثر معنی داری دارد( 33/9- = t ، 001/0 = p ).یک دوره سه ماهه تمرینات منتخب ورزشی بر نسبت دور کمر به لگن (WHR ) کودکان ۷ تا ۱۳ سال اثر معنی داری دارد( 14/7- = t ، 001/0 = p ).یک دوره سه ماهه تمرینات منتخب ورزشی بر درصد چربی کودکان ۷ تا ۱۳ سال اثر معنی داری دارد( 15/9- = t ، 001/0 = p ). نتیجه گیری : چنانچه نتایج این تحقیق نشان داد یک دوره سه ماهه تمرینات منتخب ورزشی می تواند باعث کاهش وزن و شاخص توده بدن و نسبت دور کمر به لگن و درصد چربی گردد.
Introduction: The aim of this study was to investigate the effect of a three-month period of selected sports training on the structural body composition of children aged 7 to 13 years. Research methodology: The statistical population of this study consisted of overweight girls aged 7 to 13 years in Marvdasht city, 20 of whom were voluntarily selected as a statistical sample and performed the selected exercises under the supervision of trainers for 2 60-minute sessions per week for three months. Descriptive statistics of mean and standard deviation and inferential statistics of t-test were used to examine the research data. Findings: The results of this study showed that a three-month period of selected sports training has a significant effect on weight changes in children aged 7 to 13 (t = -9.05, p = 0.001). A three-month period of selected sports training has a significant effect on changes in body mass index (BMI) in children aged 7 to 13 (t = -9.33, p = 0.001). A three-month period of selected sports training has a significant effect on waist-to-hip ratio (WHR) in children aged 7 to 13 (t = -7.14, p = 0.001). A three-month period of selected sports training has a significant effect on fat percentage in children aged 7 to 13 (t = -9.15, p = 0.001). Conclusion: If the results of this study showed that a three-month period of selected sports training can reduce weight and body mass index and waist-to-hip ratio and fat percentage.
