Physical training is known to induce a biochemical adaptive response which might require
an increase in the ingestion and/or the absorption of micronutrients. A question that is still …

Free radicals are produced during aerobic cellular metabolism and have key roles as
regulatory mediators in signaling processes. Oxidative stress reflects an imbalance between …

Exercise appears to increase reactive oxygen species, which can result in damage to cells.
Exercise results in increased amounts of malondialdehyde in blood and pentane in breath; …

High levels of reactive oxygen species (ROS) produced in skeletal muscle during exercise
have been associated with muscle damage and impaired muscle function. Supporting …

Performance of strenuous physical activity can increase oxygen consumption by 10‐to 15‐
fold over rest to meet energy demands. The resulting elevated oxygen consumption …

The present controlled-training double-blind study (supplemented (S) group, n 7; placebo
(P) group, n 10) was designed to investigate whether an antioxidant mixture (Se 150 μg …

Physical exercise may be associated with a 10-to 20-fold increase in whole body oxygen
uptake. Oxygen flux in the active peripheral skeletal muscle fibres may increase by as much …

Strenuous physical exercise induces oxidative stress. There may be a number of sources of
this oxidative stress, including mitochondrial superoxide production, ischaemia-reperfusion …

Supplementation with antioxidants received interest as suitable tool for preventing or
reducing exercise-related oxidative stress possibly leading to improvement of sport …

Background: Antioxidant supplementation has become a common practice among athletes
to theoretically achieve a reduction in oxidative stress, promote recovery and improve …
