چکیده

شیوه‌های تمرینی متفاوت مـی‌توانـد اثـر متفـاوتی بـر میزان و پاسخ هورمون‌ها داشته باشد. تمرین مقاومتی همراه با محدودیت جریان خون، یکی از روش‌های تمرینی است که به افزایش عملکرد و قدرت عضلانی منجر می‌شود. بنابراین هدف از این پژوهش، مقایسة تأثیر تمرین مقاومتی با و بدون محدودیت جریان خون بر میزان IGF-1، تستوسترون و مایونکتین سرمی مردان جوان بود. گروه‌های پژوهش شامل دو گروه تمرین مقاومتی با محدودیت جریان خون (10 نفر) و تمرین مقاومتی بدون محدودیت جریان خون (10 نفر) بود. برنامة تمرین مقاومتی به مدت چهار هفته انجام گرفت. در دو مرحلة پیش‌آزمون و پس‌آزمون، غلظــت ســرمی IGF-1، تستوسترون و مایونکتین به روش الایزا اندازه‌گیری شد. به‌منظور تعیین معنا‌داری تفاوت بین متغیرهای پژوهش از آزمون تحلیل کوواریانس یکطرفه در سطح معنا‌داری 05/0 استفاده شد. یافته‌ها نشان داد که میزان IGF-1 و تستوسترون در گروه تمرین با محدودیت جریان خون نسبت به گروه تمرین بدون محدودیت جریان خون، افزایش معنا‌داری (001/0P=) دارد، با این حال، در میزان مایونکتین افزایش غیرمعنا‌داری مشاهده شد (08/0P=). این یافته‌ها نشان می‌دهد که تمرین مقاومتی همراه با محدودیت جریان خون، در بهبود عوامل مرتبط با افزایش حجم عضلانی بسیار مؤثر است.

چکیده [English]

Different training programs have different effects on the level of hormonal response. Resistance training with blood flow restriction is one of the exercise method that leads to increase in muscle strength and performance. Therefore, the purpose of this study was to compare the effect of resistance training with and without blood flow restriction on the serum levels of IGF-1, testosterone and myonectin in young men. The research groups consisted of two groups: resistance training with blood flow restriction (10 subjects) and resistance training without blood flow restriction (10 subjects). The resistance training program was conducted for four weeks. In pre/post-test, serum concentration of IGF-1, testosterone and Myonectine was measured by ELISA method. To determine the difference between the variables, one-way covariance analysis was used at the significance level of 0/05. Our results showed that IGF-1 and testosterone levels in the exercise group with blood flow restriction were significantly higher than the exercise group without blood flow restriction (P = 0.001). However, there was a non-significant increase in myonectin levels (P = 0.08). These findings suggest that resistance training with blood flow restriction is very effective in increasing hypertrophy-related factors.
