Aim. Intense physical training can induce an increase of oxidative stress. The aim of this study was to investigate the training effect of ice hockey and long distance running on oxidative stress by assessment of serum diene conjugation (DC) and antioxidant potential (TRAP). We also analyzed serum concentration of vitamins (α-tocopherol, γ-tocopherol, retinol, β-carotene and ubiquinone-10), and maximal oxygen uptake (VO2max) in the beginning of the season.
Methods. Twenty-three male top national level long distance runners and 35 national ice hockey players were tested three times during one season.
Results. There were no differences between groups in S-TRAP. However, S-DC level was 46-53% higher (P=0.001) on ice hockey players compared with runners. S-DC correlated negatively with VO2max (r=-0.651, P=0.001), and positively with weight (r=0.608, P=0.001) among all athletes.
Conclusion. The results suggest that high intensity and intermittent type of training, such as imposed on ice hockey players, is associated with greater oxidative stress induced lipid peroxidation (higher DC) than low intensity and continuous type of training, such as imposed on runners, and better maximal oxygen uptake (VO2max). The lower level of lipid peroxidation may indicate better the prevention of cell damage.
