چکیده

هدف: هدف پژوهش حاضر مقایسه هشت هفته تمرین هوازی و مصرف مکمّل سیر بر مقادیر عوامل رشدی GH و IGF-1 و همچنین هورمون جنسی استروژن سرمی زنان جوان دارای اضافه وزن بود.
روش: تعداد 40 نفر از داوطلبان به‌عنوان نمونه آماری به‌صورت هدفمند و در دسترس انتخاب شده و سپس به‌صورت تصادفی به چهار گروه: گروه تمرین هوازی (10)، گروه مکمّل سیر (10)، گروه تمرین و مکمّل (10) و گروه کنترل (10) تقسیم شدند. معیارهای ورود به پژوهش شامل: زنان دارای عدم مصرف دارو یا مکمّل خاصی طی شش ماه اخیر، آمادگی برای انجام فعالیت ورزشی براساس پرسشنامه PAR-Q، BMI بین 25 تا 9/29، دامنه سنّی بین 20 تا 40 سال، عدم داشتن بیماری‌‌هایی نظیر دیابت، مشکلات مفصلی مانند آرتروز و عدم داشتن مشکلات تنفسی مزمن بود. برنامه تمرینی گروه هوازی شامل 24 جلسه تمرین بود.، مدت جلسه تمرینی در شروع 40 دقیقه و در طول 8 هفته به 55 دقیقه رسید. شدت تمرین 50 تا 70 درصد ضربان قلب بیشینه بود که در هفته هشتم به 65 الی 80 درصد ضربان قلب بیشینه رسید. همچنین هر روز و به مدت هشت هفته، به گروه‌های مصرف‌کننده مکمّل سیر500 میلی گرمی مکمّل سیر (به شکل کپسول)، و به گروه دارونما، کپسول‌های 500 میلی‌گرمی گلوکز مشابه کپسول‌های مکمّل، سیر داده شد. به منظور تجزیه و تحلیل آماری از آزمون شاپیروویلک جهت بررسی توزیع بودن طبیعی داده‌‌ها و تجانس واریانس با استفاده از آزمون لوین بررسی شد. جهت آزمون فرضیه‌ها از آزمون t همبسته جهت بررسی تفاوتهای درون گروهی و از آزمون تحلیل کوواریانس جهت بررسی تفاوت‌های بین گروهی استفاده شد. همچنین سطح معنی‌‌داری نیز برای تمام محاسبات (α≤0/05) در نظر گرفته شد.
یافته‌‌ها: نتایج تحلیل کوواریانس نشان داد که تفاوت معنی‌‌داری در مقادیر پس‌آزمون هورمون رشد، عامل رشد شبه انسولینی-1 و استروژن، بین سه گروه مشاهده شد (P<0/01). نتایج t همبسته تفاوت معنی‌‌داری در مقادیر هورمون رشد، عامل رشد شبه انسولینی-1 و استروژن را در سه گروه تجربی به غیر از گروه کنترل نشان داد (P<0/05).
نتیجه‌گیری: نتایج پژوهش حاضر نشان داد که هشت هفته تمرین هوازی و مصرف مکمّل سیر، منجر به افزایش عوامل رشدی GH و  IGF-1و همچنین هورمون جنسی استروژن در زنان جوان دارای اضافه وزن می‌‌شود. لذا می‌‌توان تمرین هوازی و مصرف مکمّل سیر را به زنانی که دارای اضافه وزن می‌‌باشند، توصیه نمود.

چکیده [English]

Purpose: The purpose of this study was to compare eight weeks of aerobic exercise and garlic supplementation on the levels of growth factors GH and IGF-1 as well as the sex hormone estrogen in the serum of overweight young women.
Method: 40 volunteers were selected as a statistical sample in a purposeful and accessible manner and then randomly divided into four groups: aerobic exercise group (10), walking supplement group (10), exercise and supplement group (10) and control group (10). 10) were divided. The criteria for entering the research include: women who have not taken any medicine or supplement during the last six months, are ready to do sports based on the PAR-Q questionnaire, BMI between 25 and 29.9, age range between 20 and 40 years, not having diseases such as Diabetes, joint problems such as arthritis and not having chronic breathing problems. The training program of the aerobic group included 24 training sessions. The duration of the training session was 40 minutes at the beginning and reached 55 minutes during 8 weeks. The training intensity was 50-70% of the maximum heart rate, which reached 65-80% of the maximum heart rate in the eighth week. Also, every day and for eight weeks, 500 mg of garlic supplement (in capsule form) was given to the garlic supplement consuming groups, and 500 mg glucose capsules similar to the garlic supplement capsules were given to the placebo group. For the purpose of statistical analysis, the Shapiro-Wilk test was used to check the normal distribution of the data and homogeneity of variance using the Levine test. In order to test the hypotheses, the correlated t-test was used
to examine intra-group differences and the analysis of covariance test was used to examine
inter-group differences. Also, a significant level was considered for all calculations (α≤0.05).
Findings: The results of covariance analysis showed that there was a significant difference in the post-test values of growth hormone, insulin-like growth factor-1 and estrogen between the three groups (P<0.01). Correlated t results showed a significant difference in the amounts of growth hormone, insulin-like growth factor-1 and estrogen in the three experimental groups except the control group (P<0.05).
Conclusion: The results of the present study showed that eight weeks of aerobic exercise and garlic supplementation lead to an increase in the growth factors GH and IGF-1 as well as the
sex hormone estrogen in overweight young women. Therefore, aerobic exercise and garlic supplementation can be recommended to overweight women.
