چکیده
زمینه و هدف: هدف از تحقیق حاضر بررسی تاثیر چهار هفته تمرین پلیومتریک و مکمل امگا 3 بر غلظت سرمی عامل نروتروفیک مشتق از مغز و پروتئین واکنش گر C مردان فعال بود. روش تحقیق:28 دانشجوی مرد به طور تصادفی به چهار گروه (مکمل+تمرین، مکمل، تمرین، کنترل)، تقسیم شدند. آزمودنی های گروه مکمل امگا 3 +تمرین (ترکیبی) و گروه تمرین به مدت 4 هفته برنامه تمرینات منتخب پلیومتریک را اجرا کردند. همچنین گروه ترکیبی و گروه مکمل روزانه 2000 میلی گرم مکمل امگا 3 مصرف کردند. سطوح عامل نروتروفیک مشتق از مغز و پروتئین واکنش گر C به روش الایزا و ایمونوتوربیدیمتری اندازه گیری شدند. از آزمون تحلیل واریانس یک طرفه برای بررسی تفاوت بین گروه ها و ضریب همبستگی پیرسون برای بررسی رابطه بین متغیرها استفاده شد. سطح معنی داری P<0/05منظور گردید. یافته ها: سطوح سرمی عامل نروتروفیک مشتق از مغز پس از 4 هفته تمرین پلیومتریک همراه با مصرف امگا 3 در مقایسه با گروه کنترل، افزایش معناداری یافت (p =0/04) ، اما پروتئین واکنش گر C تغییر معناداری نکرد .(p =0/53) همچنین بین مقادیر عامل نروتروفیک مشتق از مغز و پروتئین واکنش گر C گروه های مختلف پژوهش رابطه معنی داری مشاهده نشد (P<0/05). نتیجه گیری: اجرای تمرینات پلیومتریک همراه با مصرف مکمل امگا 3، موجب افزایش میزان عامل نروتروفیک مشتق از مغز سرم آزمودنی ها شد. احتمالا پروتکل مورد استفاده در تحقیق حاضر می تواند بر سلامت مغز تأثیر بگذارد، اما بین عامل نروتروفیک مشتق از مغز و پروتئین واکنش گر C به عنوان شاخص التهابی رابطه معناداری مشاهده نشد. بنابراین برای نتیجه گیری در رابطه با نقش درمانی یا حفاظتی عامل نروتروفیک مشتق از مغز در مقابله با التهاب، به مطالعات بیشتری نیاز است.

چکیده [English]
Background and Aim: The aim of the present study was to investigate the effects of 4 weeks plyometric training and omega 3 supplementation on serum brain derived neurotrophic factor (BDNF) and C reactive protein (CRP) concentration in active men. Materials and Methods: 28 physical education students randomly divided into four groups including control (n=7), omega 3 (n=7), training (n=7), and training+ omega 3 (n=7) groups. The training and training+ omega 3 groups performed 4 weeks of selected plyometric training. Also supplementary and combination groups consumed 2000 mg omega 3 daily for 4 weeks. Blood samples were taken in fasting state before and after training in order to measurement of BDNF and CRP. Moreover, BDNF and CRP were measured using ELISA and immunoturbidimetric assay respectively. Data were analyzed using one-way ANOVA and Pearson correlation coefficient and significant level was considered if pResults: Four weeks of plyometric training along with omega 3 supplementation increased serum BDNF concentration of active men significantly (P<0.04), but this treatment didn’t change CRP significantly (P<0.53). Also BDNF and CRP levels did not show any significant correlation (p<0.05). Conclusion: Plyometric training along with omega 3 supplementation can increase serum level of BDNF, suggesting that performed training protocol has positive effects on brain health. But BDNF and CRP as inflammatory markers had no significant relationship. So, more studies on the therapeutic and protective effects of BDNF against inflammation are required.
