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

Table 2

Mean (±SD) of the redox status in plasma and erythrocytes of aminothiols in ultramarathon athletes before (pre) and immediately after (post) 50 and 100 km race. Concentrations of various forms are expressed in mol⋅L−1. Significant differences compared to prerace: ( symbol), (# symbol), and ( symbol).
