چکیده

عوامل خطرزایی قلبی عروقی مکانیسم مهمی در بروز دیابت نوع دو و بیماری‌های قلبی-عروقی است، ازاین‌رو هدف پژوهش حاضر بررسی تأثیر تمرین هوازی و مکمل اسپیرولینا بر برخی عوامل خطرزایی قلبی عروقی در زنان مبتلا به دیابت نوع دو دارای اضافه وزن بود. در این مطالعۀ نیمه‌تجربی تعداد 28 نفر از زنان دیابتی نوع دو و دارای اضافه وزن با میانگین سن 7/7±5/49 سال به‌صورت تصادفی در گروه‌های هوازی+اسپیرولینا، هوازی+دارونما، اسپیرولینا و دارونما قرار گرفتند. برنامۀ تمرین هوازی شامل 6 هفته (هر هفته 3 جلسه) با شدت 60 تا 70 درصد ضربان قلب بیشینه انجام گرفت. گروه‌های دریافت‌کنندۀ مکمل، روزانه سه کپسول 500 میلی‌گرمی اسپیرولینا قبل از هر وعدۀ غذایی به مدت 6 هفته دریافت کردند. نمونه‌های خونی طی شرایط ناشتایی در مراحل پیش و پس‌آزمون جمع‌آوری شدند. تحلیل داده‌ها با استفاده از آزمون تحلیل واریانس عاملی (4×2) و آزمون تی وابسته با سطح معناداری (05/0P ≤) با استفاده از نرم‌افزار SPSS صورت گرفت. نتایج پژوهش کاهش کلسترول، LDL و VLDL در گروه‌های تمرین-اسپیرولینا، اسپیرولینا از مرحلۀ پیش‌آزمون به پس‌آزمون نشان داد و کاهش  LDL/HDLو CHOLS/HDL صرفاً در گروه تمرین-اسپیرولینا مشاهده شد(به ترتیب (009/0p=) و(007/0p=))، همچنین HDL صرفاً در گروه تمرین-اسپیرولینا افزایش معنا‌داری نشان داد (007/0P=). همچنین تفاوت معنادار بین‌گروهی در هیچ‌یک از متغیر‌ها بین گروه‌های تحقیق مشاهده نشد. در مجموع یافته‌های پژوهش حاضر نشان داد که تمرین هوازی و مکمل اسپیرولینا تا حدودی می‌تواند سبب بهبود فاکتورهای نیم‌رخ لیپیدی شود. به‌عبارتی تمرین به‌عنوان عامل اصلی به‌همراه مکمل‌دهی اسپیرولینا توانسته است تأثیر بهتری بر بهبود عوامل خطرزایی قلبی عروقی در افراد دیابتی داشته باشد.

چکیده [English]

Cardiovascular risk factors are known as an important mechanism for the development of type 2 diabetes and cardiovascular diseases. Therefore, the aim of this study was to investigate the effect of aerobic exercise and spirulina supplementation on some cardiovascular risk factors in overweight women with type 2 diabetes. In this semi-experimental study, 28 overweight women with type 2 diabetes (mean age of 49.5±7.7 years) were randomly assigned to groups of aerobic+spirulina, aerobic+placebo, spirulina and placebo. The aerobic exercise program included 6 weeks (3 sessions per week) with the intensity of 60-70% of the maximum heart rate. The groups receiving supplementation daily received three capsules of 500 mg of spirulina before each meal for 6 weeks. Fasting blood samples were collected in pretest and posttest. Data were analyzed by factor analysis of variance (2x4) and dependent t test with significance level (P≤0.05) using SPSS software. The results of the study showed a reduction in cholesterol, LDL and VLDL in the exercise-spirulina and spirulina groups from pretest to posttest, and a decrease in LDL / HDL and CHOLS / HDL was observed only in the exercise-spirulina group)P=0.009, (P=0.007) respectively. HDL also showed a significant increase only in the exercise-spirulina group (P=0.007). There were also no significant intergroup differences in any of the variables. Overall, these findings showed that aerobic exercise and spirulina supplementation can relatively improve lipid profile factors. In other words, exercise as the main factor along with spirulina supplementation can have a better effect on improving cardiovascular risk factors in people with type 2 diabetes.
