Exercise modulation of total antioxidant capacity (TAC): towards a molecular signature of healthy aging

The objective of this article was to review the biochemical basis of the total antioxidant capacity (TAC) test and its applications to exercise science and promotion of healthy aging. Measurement of TAC allows evaluation of the antioxidant content of muscle, heart and other exercise-target organs. Acute non-regular physical exercise and body exposition to higher altitude have been associated with a considerable decrease of blood TAC. However,...
