چکیده

زمینه و هدف: رشد چاقی مرتبط با کاهش فعالیت بدنی باعث شده تا رو شهای گوناگونی برای افزایش فعالیت بدنی روزان هی کودکان در نظر گرفته شود. هدف از مطالعه حاضر بررسی تأثیر 8 هفته تمرینات طناب زنی بر آمادگی جسمانی دانش آموزان 12 – 9 ساله پسر دارای اضافه وزن بود. روش تحقیق: از بین دانش آموزان مدارس ابتدایی شهرستان سنندج در سال تحصیلی 92 – 91 ، تعداد 240 دانش آموز 12 – 9 ساله پسر به صورت خوشه ای انتخاب شده و از میان آن ها، تعداد 30 نفر به صورت تصادفی در دو گروه تجربی و کنترل قرار گرفتند. افراد حاضر در تحقیق دارای اضافه وزن یا چاق بودند. تمرینات 3 روز در هفته و به مدت 8 هفته برای گروه تجربی برگزار شد؛ اما گروه کنترل غیر از کلاس های عمومی تربیت بدنی، فعالیت بدنی منظم دیگری نداشتند. شاخص های ترکیب بدنی، استقامت قلبی- تنفسی، استقامت عضلانی و انعطا فپذیری شرکت کنندگان قبل و پس از 8 هفته مداخله با آزمون های استاندارد ارزیابی شدند. اطلاعات جمع آوری شده با روش های آماری t وابسته و t مستقل مورد تجزیه و تحلیل قرار گرفتند و سطح معنی داری  0/05>p  منظور گردید. یافتهها: در گروه تجربی بهبود معناداری در وزن، درصد چربی، شاخص توده بدن، آمادگی قلبی– تنفسی  (0/0001>p) ، نسبت دور کمر به لگن (0/03>p)، استقامت عضلانی (0/001>p) و انعطا ف پذیری (0/002>p) به دست آمد. همچنین، بین دو گروه نیز در تمامی متغیرها، اختاف معناداری به نفع گروه تجربی وجود داشت (0/05>p). نتیجه گیری: تمرینات اینتروال طناب زنی بر آمادگی جسمانی مرتبط با سامتی دانش آموزان 12 - 9 ساله دارای اضافه وزن یا چاق ، تأثیر مطلوبی دارد.

چکیده [English]

Background and Aim: Being more obese due to reduce in physical activity has made discussing effective ways to increase children’s daily physical activities. The aim of this study was to investigate the effect of rope training on physical fitness parameters in 9-12 years old overweight/obese boys. Materials and Methods: The population of this study wereconsisted of all of the primary schools in sanandaj in 2012-2013. Using cluster sampling, 240 boys students aged 9-12 were selected based on the objectives of the study and among them 30 students were selected and divided into two groups of experimental and control (each group, n=15). The participants were overweight or obese. The training program was held 3 days a week for 8 weeks for the experimental group. The control group did not have any regular activity except the general physical education classes during these 8 weeks. Body composition,cardio-respiratory endurance, shoulder girdle muscle endurance and flexibility were measured as variables of this study. Collected data has been analyzed by Paired t-test and independent t-test statistical methods and significant level was set at p .0.05≥ Results: The resultd showed significant improvement in weight, body fat percent, body mass index, cardiorespiratory fitness (p<0.0001), waist to hip ratio (p<0.03), muscle endurance (p<0.001), and flexibility (p<0.002) of the experimental group (but not control group). Moreover, the results indicated that it was between the two groups in favor of the experimental group, there were significant differences in all variables (p<0.05). Conclusion: In general, it can be stated that interval training of roping has a significant effect on overweight or obese 9-12 year-old male students’ physical fitness.
