Abstract

We aimed to characterize the plasma redox homeostasis as underlying physiological mechanisms of specific training on healthy elderly. 51 healthy volunteers were trained to endurance, resistance, Neuro-Muscular Electrical Stimulation for 12 weeks, 3 sessions/w, all applied to lower limbs. We assessed ex-post quadriceps' maximal voluntary contraction, handgrip strength, five-times-sit to stand and timed up-and-go tests, oxidative damage (lipid peroxidation, protein carbonyl groups), antioxidant enzyme activities (superoxide dismutase, Catalase, Glutathione peroxidase, Glutathione homeostasis), free thiols and total antioxidant status. We found significant difference in ex-post × protocol and in post-hoc analysis specifically for plasma superoxide dismutase activity in endurance training.
