Efectul administrării de Coenzima Q10 asupra balanţei oxidanţi/antioxidanţi în efort (Nota II).

Background. CoQ10 known as ubiquinone is present in all body cells and is indispensable for life. Its structure is like E vitamin but the antioxidant effect is powerful. Aims. We followed the influence of Co Q10 supplementation on oxidant/antioxidant balance in athletes. Methods. Two groups of soccer players were in the research: Group I control group (n=10) athletes and group II (n=10) who were supplemented with 30 mg of CoQ10 daily. The oxidant/antioxidant balance was determined pre- and post- training from the urine and saliva. The indicators for the research were malondialdehide MDA and hydrogen donors HD. Results. The comparative analyses of the post effort O/AO balance demonstrated significant increases of hydrogen donors in the urine for group II compared to group I. Significative increases occurred for MDA and DH in saliva for group II. Conclusions. CoQ10 supplementation modifies the O/AO balance more in saliva increasing the antioxidant defence.
