INTRODUCTION giving rise to ROS. 7, 8 Activation of lipid peroxidation is also one of the
manifestations of the action of ethanol. 9–11 It has been shown that the metabolism of The
reactive oxygen species (ROS) generation in biological tissues is dependent on oxygen
consumption. ethanol forms-hydroxyethyl radical in the mouse liver microsomes12 and the
generation of this free Exercise seems to generate ROS due to increased oxygen
consumption. 1, 2 The increased production of radical in hepatic tissue has also been …

Recent evidence has indicated that exercise as well as ethanol exerts oxidative stress on
vital organs/tissues of the body. However, the combination of both on the testicular
antioxidant system is not known. This study investigates the interactive effects of exercise
training and chronic ethanol ingestion on the testicular antioxidant system in rats. Male
Fisher-344 rats were treated as follows: sedentary control (SC); exercise training (ET) for 6.5
weeks; ethanol (2 g kg− 1, po) for 6.5 weeks; and ET plus ethanol for 6.5 weeks. Exercise …
