Effect of exercise on lipid peroxidation in student soccer players

Abstract

Training is conducted to improve physiological functions that can support improvement of cardio-respiratory function (O2max). However, intensive training can lead to oxidative stress, which can contribute to health problems. The purpose of this study was to evaluate the effect of training on serum lipid peroxidation levels in student soccer players. The study was pre-experimental study with a one-shot case design conducted in April 2014. Twelve student soccer players from UGM who chosen by purposive sampling and met the inclusion and exclusion criteria were involved in the study. Each subject received training in the form of O2max measurements using the yo-yo intermittent recovery test. Plasma malondialdehyde (MDA) levels were measured using the thiobarbituric acid method 30 min after O2max measurement. Pearson correlation was used to analyze the correlation between O2max and plasma MDA levels. The mean age of subject was 19.25±1.06 years old. Subjects had normal nutritional status (body mass index 20.99 ± 1.65) with mean body weight of 58.13±3.76 kg and mean height of 166.2±3.40 cm. The mean O2max score was 49.56±0.61 mL/kg/min. The mean plasma MDA level was 4.32±2.09 μmol/L. There was no significant correlation between O2max and plasma MDA levels (p=0.7717). In conclusion, training does not negatively impact oxidative stress conditions in student soccer players.
