چکیده

مقدمه: سندرم متابولیک مجموعه ای از عوامل خطرساز برای ابتلاء به بیماری های قلبی- عروقی و دیابت نوع دوم محسوب می شود. شیوع چاقی و سندرم متابولیک در اکثر مناطق جهان به ویژه کشور‌های در حال توسعه رو به افزایش است و این عامل مهمی جهت افزایش مرگ و میر و عوارض و شیوع در کل جهان می‌باشد، مطالعه حاضر با هدف بررسی تأثیر هشت هفته تمرین ترکیبی (هوازی- مقاومتی) با و بدون مصرف کنسانتره انار بر شاخص های سندرم متابولیک زنان میانسال دارای اضافه وزن و چاق انجام شد.
روش کار: این مطالعه کاربردی از نوع نیمه تجربی در سال 1394 بر روی 24 زن دارای اضافه وزن و چاق در مشهد انجام شد. افراد به صورت تصادفی به دو گروه 12 نفره تمرین ترکیبی (E) و تمرین ترکیبی+ مصرف کنسانتره انار (EPC) تقسیم شدند. تمرین هوازی با شدت 80-60% ضربان ‌قلب بیشینه و تمرینات مقاومتی، کار با وزنه با شدت 80-60% یک تکرار بیشینه اجرا شد. نحوه مکمل دهی، مصرف روزانه 50 گرم کنسانتره انار بود. نمونه‌های خونی افراد جهت اندازه گیری گلوکز، انسولین و مقاومت به انسولین 24 ساعت پیش از شروع تمرینات و 48 ساعت بعد از آخرین جلسه تمرین جمع‌آوری شد. تجزیه و تحلیل داده‌ها با استفاده از نرم افزار آماری SPSS(نسخه 20) و آزمون های شاپیرو ویلک، لون، تی وابسته و مستقل انجام شد. میزان p کمتر یا مساوی 05/0 معنی دار در نظر گرفته شد.
یافته‌ها: حداکثر اکسیژن مصرفی در هر دو گروه E و EPC به طور معنی داری افزایش یافت (01/0>p)، اما تغییرات بین گروهی معنی‌دار نبود. تغییرات سطوح گلوکز و انسولین در هر دو گروه نسبت به پیش آزمون معنادار بود (05/0>p)، اما تغییرات بین گروهی سطوح گلوکز و انسولین معنادار نبود (05/0<p). همچنین شاخص مقاومت به انسولین در هر دو گروه E و EPC کاهش معناداری نشان داد (05/0>p)، اما تغییرات بین گروهی آن‌ها معنادار نبود (05/0<p).
نتیجه‌گیری: هشت هفته تمرین ترکیبی (هوازی- مقاومتی) به همراه مصرف کنسانتره انار می‌تواند مقدار گلوکز، انسولین و مقاومت به انسولین را تحت تأثیر قرار دهد و در نتیجه می‌تواند در بهبود شاخص‌های سندرم متابولیک و استقامت قلبی و تنفسی مفید واقع شود.

چکیده [English]

Introduction: Metabolic syndrome is a combination of risk factors for cardiovascular disease and diabetes type II. The prevalence of obesity and metabolic syndrome is increasing in most parts of the world especially developing countries and this is an important factor for increased mortality and morbidity and complications and prevalence in the whole world. This study was performed with aim to investigate the effects of eight weeks of combined training exercise with and without pomegranate concentrate consumption on metabolic syndrome indexes in middle-aged obese and overweight women.
Methods: This semi-experimental practical study was performed on 24 middle-aged‌ obese and overweight women at Mashhad in 2015. They were randomly divided into two groups of combined exercise (E) and combined exercise with pomegranate concentrate consumption (EPC) and each group consisted of 12 cases. The aerobic exercise was conducted with 60-80% an intensity of Maximal Heart Rate (HRmax), and resistance exercise and working with weights with intensity of 60-80% of One Repetition Maximal (1-RM) were performed. Blood samples were collected for the measurement of glucose, insulin and insulin resistance 24 hours before exercise and 48 hours after the last training session. Data were analyzed with SPSS software (version 20) by Shapiro-Wilk, Levene, dependent and independent t-test. P ≤0.05 was considered statistically significant.
Results: Maximum amount of oxygen consumed (VO2max) was increased significantly in both E and EPC groups (P<0.01), but intergroup changes were not significant. Changes of blood glucose and insulin were significant in both groups compared with pretest (P<0.05), but intergroup changes of glucose and insulin were not significant (P>0.05). However, insulin resistance showed a significant decrease in both groups (E and EPC) (P <0.05), but intergroup changes were not significant (P>0.05).
Conclusion: Eight weeks of combined exercise (aerobic and resistance) with pomegranate concentrate can significantly affect glucose, insulin and insulin resistance levels, so can be useful in improved metabolic syndrome indexes and cardiovascular and respiratory endurance.
