Objective:The aim of this study was to investigate the effect of 6 weeks of high intensity interval training (HIIT) on the serum levels of oxidative stress parameters(malondialdehyde, superoxide dismutase and catalase) of athletics athletes in Yasouj city
Materials and Methods: In this quasi-experimental study, the statistical population was male track and field athletes in Yasuj, excluding female endurance athletes; among them, 30 female sprinters, throwers, and jumpers in the age range of 22-32 years were purposefully selected as a statistical sample and randomly divided into 2 groups of 15 (HIIT training and control).HIIT training protocol was performed at an intensity of 90% of maximum heart rate for 6 weeks (3 sessions per week). Blood samples were taken from the subjects before and after training and kits were used to measure malondialdehyde, superoxide dismutase, and catalase. Paired t-test was used to determine intra-group changes, and covariance test was used to compare between groups at a significance level of p<0.05 (p<0.05). The obtained data were analyzed with SPSS-25.
Results: The findings showed that serum levels of malondialdehyde, superoxide dismutase, and catalase in the training group after six weeks of HIIT training were significantly different from the pre-test (p=0.00). Also, serum levels of these variables were significantly different between the training group and the control group at the post-test (p=0.01).
Conclusion: The results of this study showed that in order to reduce oxidative stress and improve the antioxidant capacity of runners, HIIT exercises can be used in runners' training program.
