Action of Essential Fatty Acids on the Expression of Antioxidant Genes and Athletic Performance

"Nine soccer players (19 and 22 years old) took 1 liter/day of one experimental beverage (containing 0.2% olive oil + 0.6% DHA-S Martek). Follow-up 8 weeks. At week 8 an acute exercise season was programed.~One blood sample was taken in resting conditions at beginning of the nutritional intervention (week 0, baseline). Another two blood samples were taken at the end of the nutritional intervention, in resting (week 8, pre-exercise) and post-exercise conditions (week 8, post-exercise). Biochemical measures, oxidative damage markers on lipids, proteins and DNA, antioxidant capabilities (enzyme activities and quantity of enzyme protein and gene expression) and inflammatory markers were measured in serum, plasma, erythrocytes, neutrophils and peripheral blood mononuclear cells."
