Effect Of Aerobic, Anaerobic and Resistance Exercises on Oxidative Stress Status in Healthy Sport Practitioners

الملخص

The main aim of this study is to assess the effect of three different types of exercises on lipid peroxidation in sports practitioners. The experimental approach was used to conduct the study. Sixty-six healthy male sport practitioners were participated in this study and divided into three experimental groups, each group consist of 22 subjects, the 1st, 2nd, and 3rd groups performed aerobic (AE), anaerobic exercises (AnE), and resistance exercises (RE). Before entering their experimental program, the three groups conducted the beep test for determining the VO2max for each participant, and then the blood and urine samples were taken from each participant. Thereafter, the three groups entered their specific training program for eight weeks 3 times/week. After ending the training programs, the three groups conducted the beep test again. All statistical data analyses were performed using SPSS version 25. For checking the differences between the pre- and post-test for all groups one-way ANOVA with Post Hok-Tukey was conducted. Comparisons between pre-test and post-test within one type of exercise were performed by the paired sample t-test. The effect of the three types of exercise programs for 8 weeks on lipid peroxidation biomarker (urinary MDA level) was varied. Interestingly, the 3 types of sport exercises were found to have a great effect on increasing serum antioxidants levels and decrease the levels of urinary MDA. Following the aerobic exercise, which was found to be significantly the more effective in decreasing the level of urinary MDA than anaerobic and resistance exercises. However, the resistance and aerobic exercises have a greater effect to generate the antioxidants defense than anaerobic exercise.
