چکیده
مقدمه: اضافه وزن و چاقی موجب افزایش رزیستین و فاکتورهای قلبی_عروقی می شود. لذا هدف از تحقیق حاضر بررسی تأثیر هشت جلسه کوهنوردی به همراه مکمل چای سبز بر رزیستین و ریسک فاکتورهای قلبی-عروقی در مردان دارای اضافه وزن بود.
روشکار: در این پژوهش نیمه تجربی، 40 مرد با اضافه وزن از شهر تبریز با دامنه سنی 30 تا 40 سال حضور داشتند که در 4 گروه 10 نفره (کنترل، مکمل، تمرین و نیز مکمل و تمرین) به صورت تصادفی تقسیم شدند. مکمل چای سبز مدت هشت هفته و روزانه در سه وعده و در هر وعده 5/2 گرم مصرف شد. تمرین کوهنوردی نیز به مدت هشت هفته (هر هفته یک جلسه) از ارتفاع پایین و شدت کم شروع گردید و به صورت تدریجی ارتفاع و شدت افزایش یافت. نمونه های خون گیری نیز در دو مرحله، 48 ساعت پیش از شروع و 48 ساعت پس از پایان هشت هفته، بعد از 8 تا10 ساعت ناشتایی انجام شد. از روش تحلیل کوواریانس چندمتغیره و تک متغیره برای بررسی فرضیهها استفاده شد.
یافتهها: نتایج نشان داد که هشت جلسه کوهنوردی به همراه مکمل چای سبز بر کاهش رزیستین و ریسک فاکتورهای قلبی-عروقی (hs-CRP، TG) مردان دارای اضافه وزن تاثیر معنیداری دارد (05/0P<)، اما بر ریسک فاکتورهای قلبی-عروقی (LDL-C، HDL-C) تاثیر معنیداری نداشت (05/0 P>).
نتیجهگیری: به نظر می رسد کوهنوردی به همراه مکمل چای سبز می تواند بر کاهش رزیستین و ریسک فاکتورهای قلبی-عروقی در مردان دارای اضافه وزن مفید واقع شود.

چکیده [English]
Introduction: Overweight and obesity increase resistin and cardiovascular factors. Therefore, the aim of the present study was to investigate the effect of eight sessions of mountain with green tea supplementation on resistin and cardiovascular risk factors in overweight men.
Methods: In this quasi-experimental study, 40 overweight men from Tabriz, aged 30 to 40 years, were randomly divided into 4 groups of 10 (control, supplement, exercise, and supplement and exercise). Green tea supplementation was consumed for eight weeks in three meals a day, 2.5 grams per meal. Mountain climbing training also started at low altitude and low intensity for eight weeks (one session per week) and gradually increased in altitude and intensity. Blood samples were also collected in two stages, 48 hours before the start and 48 hours after the end of the eight weeks, after 8 to 10 hours of fasting. Multivariate and univariate analysis of covariance were used to test the hypotheses.
Findings: The results showed that eight sessions of mountain climbing with green tea supplementation had a significant effect on reducing resistin and cardiovascular risk factors (hs-CRP, TG) in overweight men (P<0.05), but had no significant effect on cardiovascular risk factors (LDL-C, HDL-C) (P>0.05).
Conclusion: It seems that mountain climbing with green tea supplementation can be beneficial in reducing resistin and cardiovascular risk factors in overweight men.
