Abstract
Background and Objectives: The warm-up exercise period by decreasing oxygen deficit could decrease the free radical production. The aim of this research was to study the effect of low intensity warm-up on plasma antioxidant enzymes and on lipid, protein and DNA damage after intensive activity in a group of non-athlete males.
Materials and Methods: Firstly, subjects VO2peak were measured by Gas analyzer (Meta Max 3B) on the ergometer bicycle with incremental test. Work rate in the low intensity warm up were calculated for each subjects on the VO2peak chart. After a week subjects in the two sessions with 48 hours interval which in each session divided to two groups warm up with low and non-warm up group. Two groups in each session performed resting blood sampling then first group warm up with low intensity for six minutes and then perform intensive activity and Second group without warm up directly performed intensive activity. Blood sampling performed after two hours of the intensive activity. In the next session changed place of members in groups by cross design method. Using paired sample T test for statistic analyze.
Results: Serum levels of malondialdehyde and supper oxide dismutase were more pronounced in warm-up group but their difference with non-warm-up group was not significant, mean differences of carbonyl-protein and 8-hydroxy-2-deoxy Guanosine CAT and GPX were significantly increased in warm-up group.
Conclusion: low intensity warm up can decreased lipid damage but does not prevent protein and DNA damage in non-athlete males.
