چکیده

هدف از پژوهش حاضر، تعیین تأثیر دوره کاهش 70 درصدی تمرینات بر قدرت، توان وضعیت کاتابولیکی و آنابولیکی دوندگان بود. 14 دونده مرد با میانگین سنی 06/4 ± 50/23 سال، قد 95/5 ± 21/178، درصد چربی 16/3 ± 93/9 داوطلبانه شرکت کردند. بعد از آزمون اول تمرینات فزاینده 8 هفته‌ای شروع شد. آزمون دوم بعد از هفته هشتم گرفته شد. به دنبال آن، فاز کاهش حجم تمرین شروع شد. گروه تیپر دوره 14 روزه کاهش 70 درصد حجم تمرین را سپری کردند و گروه کنترل با همان بار قبلی، تمرینات را ادامه داد. پس از 14 روز آزمون سوم در شرایطی مشابه گرفته شد برای تحلیل داده­ها از آزمون تحلیل واریانس با اندازه­گیری­های مکرر و آزمون تعقیبی بونفرونی در سطح معنی­داری (05/0P<) استفاده شد.  نتایج نشان داد در گروه تیپر قدرت و توان طی دوره کاهش حجم تمرین بهبود معنی­داری دارد (05/0P<). سطوح پلاسمایی غلظت استراحتی تستوسترون و کورتیزول، نسبت تستوسترون به کورتیزول طی دوره تیپرینگ تغییرات معنی­دار نداشت (05/0P>). دوره کاهش 70 درصدی حجم تمرینات دوندگان 14 روز قبل از مسابقه، می‌تواند علاوه بر رفع خستگی؛ فاکتورهای قدرت و توان را به‌خوبی توسعه دهد که این مستقل از تغییرات شاخص­های کاتابولیکی و آنابولیکی است.

چکیده [English]

The purpose of this study was to determine effect the period of decrease 70 percent in training volume on strength, power, anabolic and catabolic status of runners. Fourteen man runners with average age 23/50± 4/06 years, high 178/21± 5/95, fat percent 9/93 ± 3/16 voluntarily participated. After taken the first test 8 week progressive training was started. Second test was taken after eight weeks. Follow that decrease training volume phase began. Taper group past 14 days decrease 70 percent training volume, control group followed training with previous same loading. After 14 days the third test was taken in same circumstances to previous tests. For data analyze analysis of variance (ANOVA) with repeated measures and Bonfronie post hoc tests were taken (P<0/05). Results showed in taper group, strength and power during taper phase improved significantly (P<0/05). But in control this variation wasn’t significant (P>0/05).During taper phase the plasma levels of testosterone, cortisol and testosterone to cortisol ratio was not significantly change (P>0/05). Period of decreased 70 percent training volume in runner during 14 days before main contest could in addition to decrease fatigue accumulation, improve strength and power. that is independent of variation in catabolic and anabolic indices.
