چکیده مقاله

Abstract Introduction: The purpose of the present study was to investigate the effect of barberry juice supplementation after a single exhausting aerobic activity on level of electrical muscle activity (emphasis on the fatigue) of the selected muscles of lower extremity and the serum malondialdehyde index (MDA) in inactive male student. Methods: 12 healthy and inactive students with mean age of 22/66±1/33 years, weight of 74/25±3/20 kg and BMI (234.25 ± 0/8583) kg / m2, respectively) participated in this study. They performed Bruce's test twice a week interval, first, blood samples were taken from the subjects and then they participated in an exhausted activity session and again 10 minutes after the second blood test were performed. After a two-week intervention of barberry juice consumption, the previous steps were repeated. As the same, the muscle electrical activity of lower extremity muscle were recorded during the Bruce test protocol before and after the supplement consumption. Data were analyzed using MATLAB and SPSS software and one-way analysis of variance Results: Results showed no significant effect on MDA supplementation (P >0.05), however the electrical activity of some muscles as: gastrocnemius, soleus, vastus lateralis and semitendinosus was significantly decreased (P <0.05), but had no significant effect on biceps femoris muscle (P = 0.094). Conclusion: Exhausted exercise seems to cause free radicals in exercise activities, and the consumption of barberry juice has no significant effect to reduce this free radicals factors, but it can useful and effective in reducing fatigue and exhaustion during exercise.
