Abstract
2
Objective: The aim of this study was to investigate how physical fitness level could affect
3
antioxidants activities and malondialdehyde level at rest and in response to exhaustive
4
exercise in healthy older adults. Methods: Fifty older adults (average age: 66.1 ± 3.8) were
5
divided according to their physical fitness level into an unfit group (n = 15, UG), low fitness
6
level group (n = 18, LFG) and high fitness level group (n = 17, HFG). Fitness status was
7
classified based on answers to a questionnaire about lifetime physical activity history in the
8
past 12 months. Before and after an incremental cycle ergometer test to exhaustion, the
9
following markers were assessed: superoxide dismutase (SOD), glutathione peroxidase
10
(GPX), glutathione reductase (GR), ascorbic acid, α-Tocopherol, and malondialdehyde
11
(MDA).
