Effects of concurrent exercise training on the oxidative stress biomarkers concentration in elderly men

Introduction: Excessive generation of free radicals, especially reactive oxygen species (ROS) play a general role in the acceleration of aging process. Nevertheless, there is increasing evidence indicats that elderly men who are physically active are benefited from exercise-induced adaptation in cellular antioxidant defensive systems. Therefore, the aim of this study was to study the effect of concurrent training on malondyaldeyde (MDA) and carbonyl protein (PC) concentrations in elderly men. Materials and Methods: Twenty four inactive elderly men voluntarily participated in this research and were assigned in one of the training or control groups. Participants in training group performed three days per week of concurrent training for fourteen weeks. At baseline and after 14 weeks, blood samples were obtained for MDA and PC concentration measurements. Results: After 14 weeks of concurrent training, we observed a significant decrease in MDA in the training group compared with control group (p
