چکیده

مقدمه و اهداف
افراد مبتلا به سندروم متابولیک در معرض خطر بیشتر افزایش کلسترول، فشار خون بالا و انسداد عروق کرونر هستند و قطعا شناسایی تاثیر همزمان تمرین هوازی بر وخامت کلی خطر متابولیک و لیپوپروتئین‌ غیرپرچگال (به عنوان شاخص معتبر، ارزان و سهل­الوصول رویدادهای آتروژنیک) در بیماران مبتلا به سندرم متابولیک بسیار کاربردی و جذاب است.
مواد و روش­ها
روش تحقیق از نوع تجربی با طرح پیش‌آزمون-پس‌آزمون بود. 30 مرد بیمار سندرم متابولیکی غیرفعال داوطلب از شهر تبریز (سن: 2/16±5/55 سال، شاخص توده بدنی 5/2±09/30 کیلوگرم بر متر مربع)، پس از تعیین مقدار قند، پروتئین، چربی و کالری دریافتی روزانه با استفاده از ثبت یادآمد غذایی و تحلیل توسط نرم­افزار N4 و خون‌گیری، به طور تصادفی به دو گروه کنترل (15=N) و تجربی (15=N) تقسیم شدند. گروه تجربی به مدت هشت هفته در برنامه هوازی با شدت متوسط شرکت کردند و در پایان اندازه­گیری­ها تکرار شد. از آزمون‌های t همبسته، تحلیل کواریانس اندازه‌گیری مکرر، t مستقل و آزمون کاپا برای تحلیل داده‌ها استفاده شد.
یافته‌ها
در طول پژوهش تفاوت معناداری در مقدار پروتئین، قند، چربی و کل مواد غذای مصرفی روزانه مشاهده نشد (05/0>P).در گروه تجربی به دنبال تمرین هوازی بیشتر شاخص­های خطر متابولیک (فشار خون میانگین سرخرگی، مقدار قند خون، لیپوپروتئین کم­چگال، مقدار امتیاز z سندرم متابولیک و همچنین لیپوپروتئین غیرپرچگال) کاهش معناداری یافتند و مقدار لیپوپروتئین پرچگال افزایش معناداری داشت (05/0>P).
نتیجه‌ گیری
تمرین هوازی منظم همزمان بر کاهش لیپوپروتئین‌ غیرپرچگال و وخامت کلی z سندرم متابولیک مؤثر است که در کاهش خطر بروز بیماری‌های قلبی بسیار اهمیت دارد.

چکیده [English]

Background and Aim: Patients with metabolic syndrome are more prone to elevated cholesterol, hypertension, and coronary diseases. Determining synchronized effects of aerobic training on both overall metabolic risk and also NON0HDL-c levels, as a valid, easily available, and cheap index of athrogenic events, in patients with metabolic syndrome is of practical interest in clinical settings.
Materials and Methods: The present study was conducted following an experimental method with pretest and post-test. A total of 30 sedentary volunteer patients with metabolic syndrome from Tabriz (Age: 55.5±16.2 years and BMI: 30.09±2.5 kg/m2) randomized into experimental (Ex, n=15) and control (n=15) groups after blood sampling and daily measurements of CHO, protein, lipid, and total calories using N4 software. Participants in the experimental group took part in eight weeks of aerobic training at moderate intensity and the measurements were renewed following the intervention period. The data were analyzed using paired samples t-test, ANCOVA for repeated measurements, independent t-test, and the kappa correlation coefficient.
Results: No significant within-group change was observed in the amount of dietary CHO, protein, lipid, and total calories (P>0.05). In the experimental group, the majority of metabolic risk factors (Mean arterial blood pressure, fasting blood sugar, LDL, overall metabolic z score, and NON HDL-C) decreased and the amount of blood HDL-c elevated following the intervention (P<0.05).
Conclusion: Regular aerobic exercise has an efficient impact to decrease blood NON HDL-c levels and also overall metabolic z score which is of importance in reducing the risk of cardiac diseases.
