The aim of the study was to effect of a Six-week high-intensity interval training on antioxidant capacity and lipid peroxidation in inactive men. The sample consisted of inactive men with an average age of 20.80±1.95 years. Subjects were selected using purposive sampling and were randomly divided into HIIT (N=9) and control (N=10) groups. The training program included four sets of the RAST protocol (35 meter distance) with three-minute rests between sets in the first and second week. One set was added each two weeks, i.e. five sets in the third and fourth week and six sets in the fifth and sixth week, with five-minute rests between sets. The results of the study had shown that there is no significant difference between malondialdehyde levels in the pretest and posttest in the experimental group (P=0.115). Moreover, no significant difference was observed in the control group (P=0.324). The data also show that there is a significant difference between pretest and posttest TAC levels in the experimental group (P=0.023), while no significant difference is observed in the control group (P=0.386). it is recommended that this study be replicated on athletes playing different sport. Also the HIIT protocol can be used for a longer period and/or different antioxidant enzymes can be measured.
