Comparison of the effects of an acute resistance and aerobic exercise session on the antioxidant defense system and lipid peroxidation of healthy young men

Introduction and

The effect of acute resistance and aerobic exercise on antioxidant defense and lipid peroxidation has not been fully investigated. The aim of this study is toexamine the serum total anti-oxidative capacity (TAC), bilirubin, and malondialdehyde (MDA) levels after an acute resistance and aerobic exercise in healthy young men.

This study is a semi-experimental research. 29 healthy young men participated in the study and they were randomly divided into three groups including acuteresistance exercise group (N = 10), acute aerobic exercise group (N = 10) and a control group (N = 9). Participants had no any chronic diseases, smoking and supplement foods. TAC, bilirubinand MDA were measured using by precise kit and tools. When the normal distribution of the data is revealed by Kolmogorov- Smirnov test, we applied the dependent t-test and analysis of variance for extraction of results. Significance level was considered if p 0/05.

The results showed that the levels of bilirubin (p<0.006 and p<0.005 respectively) and TAC (p<0.001 and p<0.02 respectively) significantly increased after both acute resistance and aerobic exercise; but there was no significant changes in MDA levels (p>0.05). In addition, it is observed that mean changes of antioxidant defense indices of serum had no anysignificant (P>0.05) differences between groups.Discussion and

Based on the findings, performing of an acute resistance or aerobic exercise may enhance antioxidative defense system of the body similarly and considerationto the type and mode of exercise training, it could not make any differences about induced responses to exercise.
