Abstract

Aging is characterized by a progressive decline in the physiological function due to the gradual alteration of molecules, cells and tissues. Reactive oxygen species (ROS) are the by-product of aerobic metabolism, and their increase is physiologically counteracted by the activation of the antioxidant machinery. A typical hallmark of aging is the imbalance of such equilibrium, due to either an increase of the amount of radicals or a failure of the antioxidant system. Literature reports that physical exercise is able to restore and maintain the homeostasis of oxidants and antioxidants during aging. Recently, growing interest has been turned to functional fitness, a special physical activity aimed to enhance the ability to perform everyday tasks, such as dressing, climbing stairs and preparing meals. The aim of this work was to assess whether a 24 weeksfunctional fitness program carried out on 28 elderly participants (57-86 years old) could be able to improve their oxidative status. For this purpose, dROMs (diacron Reactive Oxygen Metabolites) and BAP (Biological Antioxidant Potential) were analysed at the beginning and at the end of the study. Furthermore, both plasma and saliva protein carbonylation levels were explored through proteomics analysis
