Oxidative Stress Assessment in Response to Ultraendurance Exercise: Thiols Redox Status and ROS Production according to Duration of a Competitive Race

Figure 2

The relationships between individual plasmatic ROS production rate (μmol⋅min⁻¹) and of (a) TAC (mM), (b) TBARS (μM), (c) PC (nmol⋅mg⁻¹ protein), (d) 8-iso-PGF2α (ng⋅mg⁻¹ creatinine), (e) 8-OH-dG (ng⋅mg⁻¹ creatinine), (f) oxidized glutathione (μmol⋅L⁻¹), and total (g) Cys (μmol⋅L⁻¹), (h) CysGly (μmol⋅L⁻¹), and (i) Hcy (μmol⋅L⁻¹) recorded in 50 km (full symbols) and in 100 km (empty symbols) race are shown. The linear regression fit (solid line) and the correlation coefficient () reported for each relationship are shown too. Significant linear relationships, (§ symbol) and ( symbol), were estimated.
