چکیده

هدف: با توجه به پتانسیل بالای شکل‎پذیری عصبی در کودکان، یافتن بهترین روش‎های تمرینی برای رسیدن به سازگاری های عصبی مناسب  بسیار حائز اهمیت است. BDNFبه عنوان عضوی از خانواده نروتروفین ها، یکی از شاخص های رشد عصبی است که در پاسخ به فعالیت ورزشی افزایش می یابد .هدف اصلی این تحقیق بررسی اثر دو نوع تمرین مقاومتی ثابت و معلق بر سطوح BDNFبزاق کودکان نابالغ است.روش شناسی: 24 نفر از پسران نابالغ (میانگین سنی 55/0 3/12، مرحله 1 و2 از مقیاس تانر) در سه گروهِ تمرین مقاومتی معلق (TRX)، تمرین مقاومتی با وزن بدن (BWT)،و گروه کنترل(C) تقسیم شدند. گروه‌های تمرین، دو جلسه در هفته و به مدت هشت هفته به تمرین پرداختند. همه گروه‎ها سه روز در هفته در تمرینات منظم فوتبال شرکت می کردند. نمونه بزاق، قبل از شروع تمرینات و 72 ساعت پس از آخرین جلسه تمرین جمع‌آوری و میزان BDNFبزاق با روش الایزا سنجیده شد. از آزمونِ آنوای یک طرفه با سطح معنی داری 55/0 برای مقایسه بین گروه‌ها استفاده شد.نتایج: با وجود اینکه اثر تمرین مقاومتی بر قدرت عضلات پایین تنه در گروه تجربی به خوبی مشاهده شد، غلظت BDNFبزاق تفاوت معنی داری در بین گروه‎ها نداشت (411/0=P ، 922/0=F ).بحث و نتیجه گیری: از آن‎جا که کودکان تحت تاثیر فرآیندهای رشد و بلوغ قرار دارند، به تغییرات ناشی از فعالیت ورزشی در نروتروفین‎ها، حساسیت بیشتری دارند در نتیجه یافته‎های مشابه می‎تواند به دلیل شرکت منظم همه گروه‎ها در تمرینات فوتبال باشد.

چکیده [English]

Purpose: According to high potential of neural plasticity in childhood, it is important to find the best training methods to reach proper neural adaptation. BDNF is a member of the neurotrophins which is engaged in neuromuscular adaptations due to increased muscular activity. The main purpose of this study is to investigate the effects of two types of suspension and unsuspension resistance training on salivary BDNF of prepubescent children.
Method: 24 immature boys (mean age 12.3±0.55, Tanner stage of 1 and 2) were divided into three groups of TRX suspension training (TRX), body weight training (BWT), and control (C). Training groups completed training programs, two times a week for eight weeks. Saliva samples were collected before training and also 72 hours after last training session to measure salivary BDNF using ELIZA method. One-way ANOVA test with significance level of 0.05 was used for comparison between groups.
Results: Even though the effects of resistance training on muscle strength in the lower body was observed in the experimental group, BDNF concentrations were not significantly different (F=.922, P=.411).
Conclusion: Since children are affected by growth and maturation processes, they are more susceptible to exercise-induced changes in neurotrophins, similar results between groups, may be due to regular participation in soccer training in all three groups.
