مقدمه: چاقی با افزایش استرس اکسایشی بدن همراه است. به علاوه، فعالیت ورزشی باعث افزایش استرس اکسایشی می شود. با این حال مصرف مکمل های غذایی ممکن است باعث تعدیل این شاخص ها شود.هدف: لذا مطالعه حاضر تاثیر مصرف بذرکتان بر ظرفیت آنتی اکسیدانی تام پلاسما و شاخص پراکسیداسیون لیپیدی دختران دارای اضافه وزن متعاقب چهار هفته تمرین ترکیبی بررسی می کند.روش بررسی: سی و شش زن دارای اضافه وزن با 25

Effect of Flaxseed Supplementation and Concurrent Physical Activity on Total Antioxidant Capacity of the Plasma and the Lipid Peroxidation Index of Overweight Women

Background: Obesity is associated with increased oxidative stress. In addition, exercise can increase oxidative stress effects. However, the use of dietary supplements may moderate these indices.Objective: The present study is conducted to assess the effect of flaxseed supplementation on the total antioxidant capacity and lipid peroxidation after four weeks concurrent training in overweight women.Methods: Thirty six overweight women with BMI> 25 were randomly divided into four groups of 9 people, including supplementary training, concurrent training, supplementation flaxseed and control. All written consent was taken. Concurrent training included aerobic exercises with an intensity of 65% of heart rate and resistance training with intensity of 60% 1RM In between the Flaxseed powder (0.62 g per kg of body weight per day) was supplemented during the fourweek period. Hypothesis research at the level of significance P <0.05 was used to analyze the variance (ANOVA) with repeated measurements with intergroup factor.Results: The results showed that the concentration of malondialdehyde biomarker in the nonflax seed group increased significantly after the concurrent training (P <0.05). However, the total antioxidant capacity of plasma was not significantly different (P> 0.05).Conclusion: The results of this study indicated that acute concurrent Physical activity give rise to increased MDA concentration in overweight women. The application of flaxseed extract employed as an antioxidant supplement might ameliorate this marker and prevent the oxidative stress damage.
