چکیده
هدف: تغییرات در محور هیپوتالاموس- هیپوفیز احتمالا با تغییرات در هورمونهای جنسی در ارتباط است. تمرینات‌بدنی نیز یکی از فاکتورهای موثر در تغییرات این محور است. هدف از مطالعه حاضر، بررسی تاثیر شش هفته تمرین مقاومتی بر سطوح سرمی تستسترون آزاد، گلوبولین متصل شونده به هورمونهای جنسی، اینهیبین b، هورمون لوتئینی و محرک فولیکولی در دانشجویان مرد چاق بود. روش شناسی: برای این منظور بیست دانشجوی پسر چاق با دامنه سنی2±20 سال در این پژوهش شرکت نمودند و به صورت تصادفی به دو گروه 10 نفری تمرین مقاومتی و کنترل تقسیم شدند. تمرین مقاومتی در مدت شش هفته و سه جلسه در هفته و با شدت 60% تا 70% یک تکرار بیشینه اجرا شد. به منظور آنالیز متغیرهای بیوشیمیائی نمونه‌های خونی در دو مرحله 48 ساعته قبل و بعد از دوره تمرینی گرفته شد. تغییرات درون‌گروهی و بین گروهی اطلاعات با آزمون t وابسته و مستقل انجام پذیرفت. یافته‌ها: نتایج این مطالعه نشان داد که تمرین مقاومتی منجر به افزایش معنی دار غلظت سرمی تستسترون آزاد و افزایش معنی دار SHBG در مردان چاق شد. اما بعد از شش هفته تمرین، تغییر معنی داری در اینهیبین b، هورمون لوتئینی و هورمون محرک فولیکولی مشاهده نشد. بحث: شش هفته تمرین مقاومتی به همراه بهبود ترکیب بدنی، قدرت عضلانی بالاتنه و پائین تنه و هم چنین توان هوازی با تغییرات هورمونهای جنسی در مردان در ارتباط است.

چکیده [English]
Aim: Changes in the hypothalamo-pituitary axis are probably related to changes in sex hormones. Physical training is one of the effective factors in the changes of this axis. purpose of this study was the effect of six weeks of ResistanceTraining on free Testosterone serum levels, sex hormones binding globuline, Inhibin b and luteinizing and follicle-stimulating hormone in obese men students. Methods: For this purpose, 20 obese male students with aged range of 20 ± 2 years participated in this study and divided randomly into 2 groups 10 people of resistance training and control. Resistance training was performed for six weeks and three sessions per week in %60 to %70 repetition maximun. In order to analyze the biochemical variables, blood samples were taken at two stages, 48 hours before and after of training period. Inter group and between changes of information were performed by dependent and independent t-test. Results: The results of this study showed that resistance training led to a significant increase in free testosterone serum concentration and a significant increase in SHBG in obese men. But after six weeks of training, there were no significant changes in inhibin b, luteinizing hormone and follicular stimulation hormone. Conclusion: six weeks of resistance training with improved body composition, upper and lower body muscle strength and also aerobic power are associated with changes in sex hormones in obese men.
