Response of lipid proxidation and antioxidant system to single bout of high intensity interval exercise in elite soccer players

Free radicals can cause lipid proxidation، especially in athletes. The aim of this research was to determine the response of lipid exercise proxidation and antioxidant system to single bout of High Intensity interval Exercise (HIE) in elite soccer players. In this semi experimental study، 20 football players were selected randomly and divided into experimental and control groups. Both groups participated in high intensity interval exercise protocol. The collected data were analyzed using t-test. The results showed that HIE protocol could significantly increase MDA and GPX in experimental group (P<0. 05). But، Intensive exercises didn''t significantly change the SOD Indexes in experimental group. The present research results indicate that as a result of a single bout of high intensity interval exercise (HIE)، the body is exposed to risk of oxidative stress. In addition، antioxidant system can provide high anti oxidative protection for organism
