چکیده

تمرینات مقاومتی (RT) از مهم‌ترین برنامه‌های تمرینی در بیشتر ورزش‌ها از جمله ورزش سنگ‌نوردی است. این تمرینات از طریق افزایش قدرت و استقامت عضله نقش مهمی در بهبود عملکرد ورزشی دارد. به‌تازگی استفاده از محدودیت جریان خون (BFR) به‌عنوان روشی برای بهبود کارایی RT پیشنهاد شده است. ازاین‌رو هدف از تحقیق حاضر، بررسی تأثیر 4 هفته تمرین مقاومتی با و بدون محدودیت جریان خون بر عوامل هورمونی آنابولیک، نیتریک اکساید و لاکتات مردان سنگ‌نورد بود. در این تحقیق نیمه‌تجربی، به‌صورت هدفمند 20 سنگ‌نورد مرد نخبه با میانگین سنی 42/1±3/23 سال و درصد چربی 25/2±1/13درصد و حداقل 2 سال سابقة تمرینی با تخصیص تصادفی در دو گروه تمرین با BFR و تمرین بدون BFR قرار گرفتند. برنامة تمرین مقاومتی 3 جلسه در هفته و به مدت 4 هفته و هر جلسه به مدت 80 دقیقه با شدت تمرین30 درصد حداکثر قدرت بیشینه با یا بدون BFR بود. خون‌گیری در چهار مرحله حالت پایه، پس از آزمون ورزشی اولیه، پس از 4 هفته تمرین در حالت پایه و بلافاصله پس از قرارداد سنگ‌نوردی پس‌آزمون به‌منظور تعیین سطوح سرمی IGF-1، NO، هورمون رشد و لاکتات خون اخذ شد. در نهایت، داده‌های حاصله با آزمون تحلیل واریانس با اندازه‌گیری مکرر در سطح معنا‌داری کمتر از 05/0 تجزیه‌وتحلیل شدند. در مرحلة پیش‌آزمون، افزایش غلظت IGF-1، NO، هورمون رشد و لاکتات در گروه BFR بیشتر از بدون BFR بود (05/0>P). علاوه‌بر این، افزایش مقادیر استراحتی NO تنها در گروه BFR معنا‌دار بود (05/0>P)، اما مقادیر استراحتی IGF-1، GH و لاکتات خون در گروه بدون BFR تغییر معنا‌داری نداشت (05/0<P). همچنین، پاسخ ورزشی IGF-1، NO و GH صرفاً در گروه BFR به‌طور معنا‌داری افزایش یافت (05/0>P). به‌نظر می‌رسد تمرین با BFR احتمالاً روشی مناسب برای دستیابی کارامدتر و موثر به سازگاری‌های تمرینی است، لیکن تا زمان انجام مطالعات بیشتر نتایج تحقیق حاضر باید بااحتیاط استفاده شود.

چکیده [English]

Angiogenesis and increased capillary density of skeletal muscle is one of the potential physiological changes during the flow restriction exercise (BFR). Therefore, the aim of this research was to evaluate the Effects of 4 weeks resistance training with and without blood flow restriction on GH, IGF-1, NO and Lactate in male rock climbers. In this semi-experimental study, 20 elite climbers (aged 23±1.43 years; body fat percent 13.1±2.25%; 2 years athletic training history) in a randomized and double-blind design were divided in two equal rock climbing with blood flow restriction (BFR) or rock climbing without blood flow restriction (NBFR) groups Resistance training program was three sessions per week for 4 weeks and each session was 80 minutes with a training intensity of 30% of maximum strength and six movements. Blood samples were obtained in the 4 phases: before and 24 hours after rock climbing protocols in per and post-test. Vascular endothelial growth factor and Growth Hormone were analyzed. Finally, Data were analyzed independent and independent T test. The significance level was set at p<0.05. In the pretest, the increase in concentrations of IGF-1, NO, growth hormone and lactate in the BFR group was greater than NBFR (P <0.05). In addition, the increase in resting NO values was significant only in the BFR group (P <0.05) but the change in resting levels of IGF-1, GH and blood lactate was not significant in the NBFR group (P <0.05). Also, the exercise induced response of IGF-1, NO and GH increased significantly in the .
