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. | ||
