چکیده

هدف: تورین یک مکمل آنتی اکسیدانی است. بنابراین هدف از انجام پژوهش حاضر اثر مکمل یاری کوتاه مدت دو دوز مختلف مکمل تورین بر پاسخ برخی شاخص های آنتی اکسیدانی بزاقی مردان جوان پس از یک فعالیت هوازی وامانده ساز می باشد.
روش کار: هشت مرد سالم غیر ورزشکار (با میانگین و انحراف معیار سن 7/1 ± 6/21 سال و حداکثر اکسیژن مصرفی 62/2 ± 62/46 میلی لیتر/کیلوگرم / دقیقه) به صورت تصادفی در دو دسته (6 گرم در مقابل 3 گرم)  طی دو دوره 7 روزه مکمل تورین را بصورت طرح متقاطع، تصادفی و دو سوکور مصرف نمودند. نمونه گیری بزاقی در سه مرحله قبل و بعد از دورة مصرف مکمل و همچنین بلافاصله پس از جلسه فعالیت هوازی وامانده ساز صورت گرفت. آزمودنی ها در فعالیت هوازی وامانده ساز روی چرخ کارسنج با سرعت  60 دور در دقیقه و شدت 20 وات رکاب زدن را آغاز کردند و در هر دقیقه 20 وات به شدت کار افزوده شد تا جایی­که آزمودنی به واماندگی رسیدند.
یافته ها: نتایج پژوهش حاضر نشان داد، میزان فعالیت آنزیم‌ SOD، پس از مکمل‌یاری و پس از فعالیت در مقایسه با پیش از مکمل‌یاری در هر دو دوز، افزایش معنی داری داشت (05/0p <). میزان فعالیت آنزیم POX و DPPH، اگرچه با مکمل یاری و فعالیت افزایش نشان داد اما بین دو دوز مکمل یاری تفاوت معنی داری مشاهده نشد.
نتیجه گیری: با توجه به یافته های پژوهش می توان گفت که احتمالاً مصرف کوتاه مدت مکمل تورین با افزایش ظرفیت آنتی‌اکسیدانی، تأثیرات منفی حاصل از افزایش رادیکال‎های آزاد در نتیجه انجام فعالیت‌های ورزشی هوازی شدید را کاهش می­دهد.

چکیده [English]

Aim: Taurine is an antioxidant supplement. Therefore, the purpose of this study was to investigate the effect of short-term supplementation of two different dosages of taurine supplement on responses of some salivary antioxidant parameters of young men after an exhaustive aerobic activity.
Methodology: Eight healthy non-athlete men (mean ± SD age 21.6 ± 1.7 yrs and VO2 max 62.62 ± 62.2 ml / kg / min) were randomly divided into two categories (3 Vs. 6 Gr/d) in two 7-day periods in the complement of taurine as cross-over, randomized and double-blinded. Saliva samples were collected in three occasions: before and after the supplementation period and immediately after exhaustive aerobic exercise. The subjects started the exhausting aerobic activity on ergometer was performed at 60 RMP and 20 watts, with, 20 watts added to the intensity every minute until the subject got exhausted.
Results: The results showed that the SOD, after supplementation (in doses of 6 grams more than the dose of 3 g) and after exercise increased significantly compared with the pre-supplementation in both doeses (p < 0.05). The activity level of POX and DPPH increased with supplementation and activity, but there was no significant difference between the two doses.
Conclusion: According to the research findings, it can be concluded that the short-term consumption of taurine supplementation by increasing antioxidant capacity will reduce the negative effects of free radicals as a result of intense aerobic exercise activities.
