چکیده

مقدمه و اهداف
اپیدمی چاقی در سراسر جهان بر سلامت عمومی تاثیر گذاشته است. هدف از مطالعه حاضر، مقایسه تاثیر تمرینات مقاومتی دایره­ای با شدت کم و شدت متوسط بر سطوح آدیپونکتین و نیمرخ لیپیدی در زنان دارای اضافه­وزن بود.
مواد و روش ­ها
۵۴ زن دارای اضافه­وزن (سن ۱۴/۲±۵۶/ ۳۱ سال، وزن ۴/۹±۴۵/۸۰ کیلوگرم، شاخص توده بدن kg/m2 ۲۱/۳±۶/۲۸) به طور تصادفی در سه گروه (هر گروه ۱۸ نفر) شامل گروه­های تمرین دایره­ای با شدت متوسط، برنامه تمرین دایره­ای با شدت پایین و شاهد قرار گرفتند. برنامه تمرین ورزشی به مدت ۸ هفته و هفته­ای 3 جلسه اجرا شد. قبل و بعد از برنامه تمرین ورزشی، سطوح آدیپونکتین و نیمرخ لیپیدی اندازه­گیری شد. به منظور تجزیه و تحلیل آماری از آمار توصیفی، آزمون آنالیز کوواریانس و آزمون تعقیبی بونفرونی استفاده شد. تجزیه و تحلیل آماری توسط نرم­افزار SPSS نسخه 20 و سطح معناداری آزمون­ها نیز 05/0≥p در نظر گرفته شد.
یافته­ ها
در ابتدای مطالعه حاضر و قبل از اعمال پروتکل ورزشی تفاوتی در مقادیر پایه آدیپونکتین بین گروه­ها مشاهده نشد (05/0<p). نتایج حاضر نشان داد که سطوح آدیپونکتین بعد از هشت هفته تمرین مقاومتی دایره­ای با شدت متوسط در مقایسه با گروه شاهد به صورت معناداری افزایش یافته است (027/0=p)، اما تغییرات آدیپونکتین در گروه تمرین با شدت پایین از نظر آماری معنادار نبود (14/0=p). کاهش سطوح LDL-c (001/0=p)، کلسترول (001/0>p) و TG (001/0>p) و افزایش HDL (001/0>p) در گروه شدت متوسط نسبت به گروه شاهد معنادار بود.
نتیجه­ گیری
بر اساس نتایج حاضر، تمرین دایره­ای با شدت متوسط توانسته در افزایش آدیپونکتین موثرتر واقع شود؛ از این رو نیمرخ لیپیدی در این گروه نیز به تبع این تغییرات بهبود معناداری به همراه داشته است.

چکیده [English]

Background and Aims: The global epidemic of obesity has affected the general health. The aim of the present study was to compare the effects of low and moderate intensity circuit resistance trainings on the levels of adiponectin and lipid profiles in overweight women.
Materials and Methods: A total of 54 overweight women [31.56±2.24 years, 80.45±9.4 kg, 28.3±6.21 kg/m2] were randomly assigned into three groups of moderate intensity circuit resistance training (MICT), low intensity circuit resistance training (LICT), and control. Exercise training program was conducted for eight weeks, three sessions per week. Before and after the exercise training program, the levels of adiponectin and lipid profiles were measured. For data analysis, descriptive statistics, analysis of covariance test and Bonferroni post hoc test were used. Data analysis was performed in SPSS, version 20, with the significance level set at p≤0.05.
Results: At the beginning of the study and before applying the exercise protocol, there was no difference in baseline adiponectin between the groups (p>0.05). The results indicated that adiponectin levels significantly increased after eight weeks of moderate-intensity circuit resistance training as compared with control group (p=0.027), but changes in adiponectin levels were not statistically significant in low intensity group (p=0.14). Decrease in the levels of LDL-c (p=0.001), cholesterol (p<0.001), and TG (p<0.001) and increase the levels of HDL-c (p<0.001) were significant in moderate intensity group compared to those of the control group.
Conclusion: According to the results obtained in the present study, moderate-intensity circuit resistance training has been shown to be effective in increasing adiponectin, therefore, the lipid profiles in this group had a significant improvement related to these changes.
