چکیده

هدف: کبد از حساس‌ترین بافت‌های هدف فشار اکسایشی ناشی از تمرین می‌باشد و آمینوترانسفراز‌های کبدی، شاخص‌های حساسی برای تعیین آسیب دیدگی سلول‌های کبدی هستند. پژوهش حاضر با هدف مقایسه تأثیر هشت هفته تمرین TRX و مقاومتی سنتی بر برخی از آنزیم‌های کبد (آسپارتات آمینو ترانسفراز و آلانین آمینو ترانسفراز) در زنان غیرفعال انجام گرفت.
روش ­ها: در این پژوهش که به روش نیمه تجربی انجام شد، 28 دختر غیرفعال با میانگین سن41/1±07/21 سال و شاخص توده بدن 25/4±52/22 کیلوگرم بر متر مربع به صورت تصادفی در سه گروه تمرین TRX، تمرین مقاومتی سنتی و کنترل قرار گرفتند. گروه­ های تجربی، تمرین مقاومتی سنتی وTRX  را سه جلسه در هفته به مدت هشت هفته با شدت 65 – 80 درصد یک تکرار بیشینه اجرا کردند، در ‌حالی‌که گروه کنترل در هیچ برنامه تمرینی در مدت زمان اجرای پژوهش شرکت نکرد. نمونه‌های خونی قبل از شروع تمرین و 48 ساعت بعد از آخرین جلسه تمرین از تمام آزمودنی­ ها گرفته شد و برای بررسی سطح سرمی آسپارتات آمینوترانسفراز (AST) و آلانین آمینوترانسفراز (ALT) مورد استفاده قرار گرفت. داده­ ها با استفاده از آزمون­های شاپیرو-ویلک، تی­وابسته و تحلیل واریانس یک­ سویه مورد تجزیه و تحلیل آماری قرار گرفت و سطح معنی ­داری 05/0P< در نظر گرفته شد.
نتایج: نتایج حاصل از تحقیق نشان داد که تفاوت معنا‌داری در میزان سرمی آنزیم‌های AST و ALT از مرحله پیش آزمون به پس آزمون در گروه‌های TRX، مقاومتی سنتی و کنترل وجود نداشت (05/0p>). همچنین تفاوت بین گروهی در هیچ یک از عوامل مشاهده نشد (05/0p>).
نتیجه­گیری: نتایج پژوهش حاضر نشان داد که هشت هفته تمرین TRX و مقاومتی سنتی بر سطح سرمی آسپارتات آمینوترانسفراز (AST) و آلانین آمینوترانسفراز (ALT) زنان غیرفعال اثر معناداری ندارد. بنابراین، اثرات اجرای تمرین TRX  و مقاومتی سنتی بر شاخص‌های آنزیمی کبد یکسان بود و بین این دو نوع روش تمرینی تفاوتی مشاهده نشد.

چکیده [English]

Purpose: The liver is one of the most sensitive tissues targeted by exercise-induced oxidative stress, and hepatic aminotransferases are critical indicators for determining liver cell damage; Therefore, the present study aimed to compare the effect of eight weeks of TRX and traditional resistance training on some liver enzymes (aspartate aminotransferase and alanine aminotransferase) in inactive women.
Methods: In this quasi-experimental study, 28 inactive girls with a mean age of 21.07 ± 1.41 years and a body mass index of 22.52 ± 4.25 kg/m2 were randomly divided into three groups: TRX training, traditional resistance training and control. Experimental groups conducted the traditional resistive training and TRX three sessions a week for eight weeks, While the control group did not participate in any training program during the study. Blood samples were taken from all subjects before starting protocol and 48 hours after the last training session and were used to analyze Aspartate aminotransferase (AST) and alanine aminotransferase (ALT). Data were analyzed using Kolmogorov-Smirnov test, dependent t-test and one-way analysis of variance, and the significance level was considered P < 0.05.
Results: The results showed that there was no significant difference in serum levels of AST and ALT enzymes from pre to posttest in TRX, traditional resistance and control groups (P > 0.05). Also, no difference between groups was observed in any of the factors (P > 0.05).
Conclusion: The results of the present study showed that there was no significant difference between TRX training and traditional resistance to serum levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in inactive women. Therefore, the effects of TRX and traditional resistance training on liver enzyme indices were the same and no difference was observed between these two types of training methods.
