The main objective of this study was to examine the chronic effect of simulated intermittent normobaric hypoxia on blood antioxidant defence capacity in swimmers. The study included 14 male and 14 female competitive swimmers performing part of land training under simulated intermittent normobaric hypoxia (O2 = 15.5%) or in normoxia. Land interval training took place twice per week, with a total...
Article history: Received on: 24/04/2015 Revised on: 14/05/2015 Accepted on: 04/06/2015 Available online: 20/06/2015 Ageing is a natural life process whose manifestations are familiar and unambiguous. Oxidative modification of cellular molecules by reactive oxygen species and impaired antioxidant mechanism play unique role in a variety of age-associated degenerations. As a defence, cells have d...
Costs of autotomy, an antipredator defence, are typically explained by impaired mobility; yet physiologically mediated costs may also play a role. Given the resemblance to wounding, a decreased immune function and an associated reduction in antioxidant defence is expected after autotomy. In line with this, after lamellae autotomy, larvae of the damselfly Lestes viridis showed lower levels of in...
PURPOSE OF REVIEW Oxidative damage is involved in cardiovascular diseases. Intervention with alpha-tocopherol, ascorbic acid and beta-carotene does not appear to reduce pathogenesis. The purpose of this review is to describe alternative antioxidant mechanisms that may be involved. RECENT FINDINGS Antioxidants with different chemical properties may recharge each other in an antioxidant network...
