Oxygen‐free radicals, reactive oxygen species (ROS) or reactive nitrogen species (RNS),
are known by their “double‐sided” nature in biological systems. The beneficial effects of …

Oxidative stress is defined as an imbalance between generation of reactive oxygen species
(ROS) and decreased antioxidant defense systems. Oxidative stress develops particularly in …

Background: Obesity is becoming a global epidemic and reversing the pathological
processes underlying obesity and metabolic co-morbidities is challenging. Obesity induced …

Purpose We examined effects of a three-game, 1-week microcycle (G1, G2, G3) on recovery
of performance and inflammatory responses in professional male footballers. Methods …

Overtraining syndrome is characterized by declining performance and transient
inflammation following periods of severe training with major health implications for the …

This study investigated the changes in oxidative stress biomarkers and antioxidant status
indices caused by a 3-week high-intensity interval training (HIT) regimen. Eight physically …

The aim of this study was to determine the effects of a simulated one-day Greco-Roman
wrestling tournament on selected performance and inflammatory status indices. Twelve …

The discovery of some additional properties and functions of reactive oxygen species (ROS),
beyond their toxic effects, provides a novel scenario for the molecular basis and cell …

Thioredoxin reductase (TRX) is a selenoprotein that reduces oxidized protein substrates in
an NADPH-dependent process (cf. Fig. 1). The thioredoxins (TX) are a family of small redox …
