Figure 5.

Panel plots of relationship between ROS production rate (μmol·min⁻¹) and (a) antioxidant capacity (nW) and (b) peak ROS production rate (μmol·min⁻¹·kg⁻¹) and V′O₂  peak (mL·kg⁻¹·min⁻¹) recorded at the end of IE in the two sessions: before (PRE Trg, full squares) and after (POST Trg, empty squares) training. The linear regression fit (solid line) is also shown and so is the correlation coefficient (r ²) reported in each panel. A significant linear relationship in the ROS production between antioxidant capacity (P < 0.0001) and V′O₂ peak (P < 0.0001) values was estimated.
