Figure 2.

The effect of a single exercise bout on vitamin B2 status (EGRAC) in high-fit and low-fit females. Baseline and post-exercise EGRAC in low-fit (N = 16, white) and high-fit (N = 15, grey) females (A). Correlation between the individual exercise response of unstimulated EGR activity ($\Delta$ unstimulated EGR activity, expressed as nmol NADPH per minute) and the exercise response of EGRAC ($\Delta$ EGRAC); the high-fit and low-fit groups are plotted together (B).
