Figure 3. Changes in circulating plasma NO2- prior to and following a maximal GXT.

Figure 3

Samples were collected prior to (pre), and 10 min following (post) GXT. Data is represented as actual NO2- yield (nM) for each group. Values are statistically adjusted for differences between groups in age and VO2peak. * = significantly different within groups at the p≤0.05 level. ** = significantly different between groups at the p≤0.01 level.
