چکیده
مقدمه: یائسگی مرحله‌ای از حیات زن است که به دلیل کاهش فعالیت تخمدان‌ها و کمبود استروژن، دوره باروری به پایان می‌رسد. از آنجایی که فشارخون و مقاومت به انسولین یکی از مشکلات اساسی در زنان مسن است، این تحقیق با هدف تأثیر تمرین ترکیبی با و بدون مصرف دانه کتان بر مقاومت به انسولین و فشارخون زنان یائسه، انجام شد.
مواد و روشها: در این مطالعه نیمه تجربی، 27 زن یائسه با دامنه سنی50تا60 سال و شاخص توده‌بدن25 تا30 کیلوگرم برمترمربع، به روش نمونه‌گیری در دسترس و هدفمند انتخاب و به صورت تصادفی به دو گروه تمرین ترکیبی(12نفر) و تمرین ترکیبی همراه مصرف دانه کتان(15نفر) تقسیم شدند. تمرین هوازی با شدت 60تا80 درصد ضربان قلب بیشینه و تمرینات مقاومتی، با شدت 60تا80 درصد یک تکرار بیشینه اجراشد. همچنین 25گرم دانه آسیاب شده در گروه تمرین ترکیبی به همراه مصرف کتان، مصرف می‌شد. نمونه‌خونی آزمودنی‌ها برای انداره‌گیری مقاومت به انسولین جمع‌آوری شدو با استفاده از نرم افزار SPSS و آزمون تی وابسته و مستقل، به ترتیب، برای مقایسه تفاوت‌های درون گروهی و بین گروهی در سطح معنی‌داری 05/0>P.استفاده گردید.
یافته‌ها: نتایج نشان داد که تمرین ترکیبی به همراه مصرف دانه کتان، به طور معنی‌داری، باعث افزایش حداکثراکسیژن مصرفی(001/0=p)، کاهش شاخص توده‌بدن(001/0=p) و کاهش فشارخون(001/0=p) شد؛ تمرین ترکیبی نیز به طور معنی‌دار موجب کاهش شاخص توده‌بدن(001/0=p) و کاهش فشارخون(001/0=p) شد.
نتیجه گیری: به نظر می‌رسد هشت هفته تمرین ترکیبی به تنهایی و همراه با مصرف دانه کتان منجر به بهبود آمادگی هوازی، ترکیب‌بدن و فشارخون در زنان یائسه می‌شود.

چکیده [English]
Introduction:Menopause is natural phenomenon and it is a stage of a woman's life in which, the menstruation period ends as a result of the reduction of the ovaries activity and the lack of estrogen. Since blood pressure and insulin resistance is a major problem in older women, The purpose of this study would be studying the The effect of combined training with and without consuming the flaxseed on the Insulin resistance and blood pressure of postmenopausal women
methods:this quasi-experimental study,27postmenopausal women with the age group of 50 to 60 years old and the BMI equal to 25 to30kg/m2, were selected using the available sampling method. Then they were randomly divided into two groups called the combined training(12people)and the combined training plus flaxseed(15people).The aerobic exercise was preformed with the intensity of 60to80 percent of the maximal heart rate and the resistance exercise with the intensity of60to80 percent of a maximal repetition .complementary was given by using25 gr of the milled flaxseed.The blood samples were collected for measuring insulin resistance and analyzed using SPSS software and Independent and independent t test, respectively, to compare intra-group and inter-group differences at a significant level of P
