چکیده

هدف : هدف پژوهش حاضر بررسی تاثیر هشت هفته پروتکل‌های متفاوت تمرین موازی بر قدرت عضلانی و سطوح سرمی تستوسترون و کورتیزول کشتی گیران جوان است. روش شناسی: 41 پسر 18-25 سال به ‌صورت تصادفی در پنج گروه: 1- استقامتی-قدرتی با فاصله ریکاوری هشت ساعت (ES8) 2- قدرتی-استقامتی با فاصله ریکاوری هشت ساعت (SE8) 3- قدرتی-استقامتی بدون ریکاوری (SE0) 4- استقامتی-قدرتی بدون ریکاوری (ES0) 5- گروه کنترل (CON) قرار گرفتند. تمرین قدرتی شامل سه نوبت 8-4 تکرار با شدت 85-90 درصد یک تکرار بیشینه بود. تمرینات استقامتی شامل دویدن به صورت تداومی زیر بیشینه با شدت 70-85 درصد از سرعت انتهایی آزمون IFT30-15 به مدت 10-30 دقیقه بود. تمرینات با تواتر سه بار در هفته به مدت هشت هفته اجرا شد. خونگیری در ساعت 8 الی 9 صبح، بعد از 12 ساعت ناشتایی بود. آزمون آنالیز واریانس یک طرفه ANOVA و η2  برای اندازه­گیری معناداری و اندازه اثر تمرین استفاده شد. برای مقایسه تغییرات درون گروهی، از آزمون  tهمبسته استفاده شد. یافته­ها: تفاوت بزرگ معناداری بین گروه SE8 با SE0، ES0 و CON (به ترتیب 04/0=P،  004/0=P و 004/0=P) در قدرت پایین تنه دیده شد. قدرت پایین تنه در دو گروه ES8و SE8 (10% و 17%) افزایش معنادار داشت. قدرت بالاتنه در گروه های ES8،  SE8و SE0 (به ترتیب 5%،10% و 4%) افزایش معناداری نسبت به مقادیر قبل از تمرین داشت. سطوح استراحتی کورتیزول در گروه SE8 (8%-) کاهش معناداری داشت. نتیجه گیری: با توجه به نتایج حاضر به نظر می­رسد اجرای تمرین قدرتی و هوازی با فاصله ریکاوری هشت ساعت (ES8 و SE8) می­تواند روش بهتری برای جلوگیری از تحلیل قدرت عضلانی بالاتنه و پایین­تنه کشتی­گیران باشد.

چکیده [English]

Aim:  The aim of this study is examine effects of different concurrent training protocols on muscle strength, Testosterone and cortisol serum levels in young wrestlers. Methods:  41 young men (18-25 year-old) were randomly divided in 5 groups: 1.endurance-strength training with 8 hours inter-Session recovery (ES8) 2.Strength- endurance training with 8 hours inter-Session recovery (SE8) 3.Strength- endurance training without recovery (SE0) 4.Endurance-strength training without recovery (ES0) 5.Control (CON). The experimental groups performed Strength training 4-8 repetitions ،85-100% 1RM and endurance training with running 10-30 minutes at 70-85 percent of final speed of IFT 30-15 test. Frequency of Session was three times a week for eight weeks. The blood sampling was performed after 12 hours fasting in 8-9 am to evaluate serum cortisol (C) and testosterone (T) concentration. One–way ANOVA and paired t-test was applied for examining training effects (α=0.05) and η2 for evaluate effect size. Results:  The result of study showed that significant difference was between SE8 with SE0, ES0 and CON on lower body strength (p=0.04, p=0.004, p=0.004). Lower body strength improved after ES8, SE8 training (10% and 17%). Upper body strength increased after ES8, SE8, and SE0 with no difference between the groups (5%, 10% and 4%). Conclusion:  Cortisol concentration decreased in SE8 (-8%). The results indicate that performing strength and endurance training with 8 hours recovery between training could improve upper and lower body strength in young wrestlers.
