Serum Paraoxonase Activity and Lipid Hydroperoxide Levels in Adult Football Players After Three Days Football Tournament

Abstract

Background: It has been suggested that physical activity is an important factor in the prevention and treatment of cardiovascular diseases. Low serum paraoxononase-1 (PON1) activity is with an associated risk of atherosclerotic disease. Objectives: In this study, we aimed to investigate serum PON1 activity and lipid hydroperoxide (LOOH) levels in adult football players after three days football tournament. Methods: Twenty-three adult male football players and 23 sedentary male subjects after three days football tournament were enrolled. Serum paraoxonase, arylesterase activities and LOOH levels were determined. Results: Serum paraoxonase and arylesterase activities were signiucantly higher in football players than sedentary subjects (all, p<0.05), while LOOH levels were significantly lower (p<0.05). Serum LOOH levels were inversely correlated with paraoxonase and arylesterase activities (r=-0.552, p<0.001; r=-0.812, p<0.001; respectively) in adult football players. Conclusion: Our data show, for the first time, that physical activity is associated with increased PON1 activity and decreased oxidative stress after three days football tournament. In addition, physical activity for a healthy life is important in increasing serum PON1 activity, and this may play a role in the prevention of atherosclerosis.
