چکیده مقاله :
هدف پژوهش حاضر بررسی تأثیر و مقایسه دو نوع برنامه تمرینی بر روی برخی از شاخص‌های ترکیب بدنی دانش‌آموزان دختر چاق شهر اهواز بود. بدین منظور تعداد 45 نفر از دانش‌آموزان چاق ناحیه یک آموزش و پرورش اهواز به صورت هدفمند انتخاب و به صورت تصادفی در سه گروه 15 نفره قرار گرفتند. گروه‌ها شامل گروه تمرین هوازی که به مدت هشت هفته و هر هفته سه جلسه تمرین هوازی با رعایت اصل اضافه بار تدریجی انجام دادند، گروه بازی که به مدت 8 هفته، بازی زو را با حجم مشابه گروه هوازی انجام دادند و گروه کنترل که هیچ گونه مداخله تمرینی نداشتند، بود. جهت کنترل برنامه غذایی آزمودنی‌ها از پرسش‌نامه یادآمد غذایی استفاده شد. شاخص‌های ترکیب بدنی شامل شاخص توده بدن (BMI)، نسبت دور کمر به دور لگن (WHR) و درصد چربی بدن در دو مرحله پیش‌آزمون و پس‌آزمون، اندازه‌گیری و ثبت شد. جهت مقایسه تغییرات درون‌گروهی، از آزمون t وابسته و مقایسه داده‌های سه گروه از تحلیل واریانس (ANOVA) با آزمون تعقیبی توکی در سطح معنی‌داری 05/0 استفاده شد. نتایج نشان داد که هشت هفته تمرین هوازی و بازی، هر دو باعث کاهش معنی‌دار شاخص توده بدن و درصد چربی بدن شدند، ولی فقط فعالیت در قالب بازی منجر به کاهش معنی‌دار نسبت دور کمر به دور لگن گردید (P<0.05). با توجه به نتایج پژوهش حاضر پیشنهاد می‌شود که جهت کنترل چاقی کودکان علاوه بر انجام برنامه‌های تمرینی سازمان‌یافته، از انجام فعالیت ورزشی در قالب بازی استفاده شود.
The purpose of the present study is the comparative review of the effect of two exercising plans on some body composition indices of the obese female girls in Ahwaz. To this aim, 45 obese students in district 1 of the education administration of Ahwaz were purposefully chosen and then they were randomly assigned to 3 groups of 15 girls. In order to control the participants’ dietary plan, the nutrition remembrance questionnaire was used. Body composition indices including body mass index (BMI), waist-hip ratio (WHR), and body fat percentage in both pre-test and post-test stages were measured and registered. For inside group comparison, dependent t-test was used and for the comparison of the 3 groups, the variance analysis (ANOVA) as well as Tuckey’s Post Hoc in the significant level of 0.05 were used. The results showed that doing 8 weeks of aerobics and playing games both significantly reduced the BMI and body fat percentage but only playing games could significantly reduce the WHR (P<0.05). According to the results of the present research, it is recommended that in order to control children obesity, in addition to organized exercises, sport activities in the form of playing be used as well.
