The health benefits of exercise are widely accepted and have been used to prevent and treat chronic diseases. Exercise, however, is also associated with production of reactive oxygen and nitrogen species (RONS) which, when in excess, can exert toxic effects such as oxidation of lipids and proteins as well as DNA damage. Because unfavourable effects...
