چکیده

مقدمه و هدف: افسردگی یکی از شایع‌ترین اختلالات روانی و یکی از بیماری‌هایی است که از نظر بار بیماری هزینۀ زیادی را به سیستم بهداشتی‌درمانی تحمیل می‌کند. هدف از تحقیق حاضر تعیین اثر یک دوره تمرینات هوازی بر سطوح خونی سروتونین و اندورفین و کاهش افسردگی زنان معتاد به موادمخدر بود.

مواد و روش‌ها: مطالعۀ حاضر یک مطالعۀ نیمه‌تجربی است. تعداد سی نفر از زنان معتاد به موادمخدر که مبتلا به افسردگی متوسط تا شدید بودند، به‌طور هدفمند انتخاب و به‌صورت تصادفی به دو گروه، تجربی (پانزده نفر) و کنترل (پانزده نفر) تقسیم شدند. گروه تجربی به‌مدت هشت هفته (سه جلسه در هفته) تمرینات هوازی را با شدت 60 تا 80درصد حداکثر ضربان قلب انجام دادند؛ ولی آزمودنی‌های گروه کنترل در این مدت در هیچ فعالیت ورزشی منظمی شرکت نداشتند. برای سنجش سطوح خونی سروتونین و اندورفین، در دو مرحله، قبل و بعد از دورۀ تمرینات ورزشی، پنج میلی‌لیتر خون از ورید بازویی آزمودنی‌‌ها اخذ گردید. داده‌ها با استفاده از آزمون t مستقل و t همبسته تجزیه‌وتحلیل شدند. سطح معنی‌داری، P<0/05 در نظر گرفته شد.

نتایج: هشت هفته تمرینات هوازی موجب افزایش معنی‌دار در سطوح خونی سروتونین و اندورفین و کاهش معنی‌دار افسردگی در گروه تجربی نسبت به کنترل شد (05/0P˂).

نتیجه‌گیری: بر اساس یافته‌ها می‌توان نتیجه‌گیری کرد که تمرینات هوازی می‌تواند بر سطوح خونی سروتونین و اندورفین و بهبود افسردگی در زنان معتاد به موادمخدر تأثیر داشته باشد.

چکیده [English]

Background and Objective: Depression is one of the most common mental disorders, which imposes a large burden on the health care system. The purpose of this study was to determine the effect of a period of aerobic training on blood levels of serotonin and endorphin and decreasing depression in addicted women to drug.
 
Materials and Methods: This study was a quasi-experimental study. A total of 30 addicted women to drug with moderate to severe depression were selected to participate as a purposeful and available sample and were randomly divided into two groups of experimental (n = 15) and control (n = 15) groups. Experimental group received 8 weeks (3 sessions per week) of aerobic exercise intensity in 60-80% of maximum heart rate, while the control group did not take part in any regular physical activity. To measure blood levels of serotonin and endorphin, in two stages, before and after training, 5 ml of blood was collected from the brachial vein of the subjects. Data were analyzed using independent and paired sample t tests. The level of significance was set at p<0.05.
 
Results: Eitgh weeks of aerobic training significantly increased blood levels of serotonin and endorphin and reduced depression in the experimental group as compared to the control (P<0.05).
 
Conclusion: According to the findings, it can be concluded that aerobic training can affect blood levels of serotonin and endorphin and improve the depression in addicted women to drug.
