Oxidative Balance in Rats during Adaptation to Swimming Load

摘要

The main parameters of free radical oxidation and antioxidant defense in the blood plasma, erythrocytes, and homogenates of skeletal muscles, heart, liver, lungs, and kidneys were studied in adult outbred albino male rats with different degree of adaptation to moderate exposure to swimming. The rats were trained to swim regularly over 1 month. Changes in oxidative balance varied in organs and tissues and depended on the level of training. Malonic dialdehyde content in the erythrocytes after swimming increased by 13.8% in non-trained animals, but decreased by 19.2% in trained rats. Parameters of blood plasma reflect the general oxidative balance of organs and tissues.
