NAD(P)H oxidase was inhibited by 1 mM apocynin (n = 5; ●) to determine the effect on mTAL mitochondrial H₂O₂ during the change in flow compared with a vehicle control group (n = 5; ○). Mitochondrial H₂O₂ is expressed as the mean ± SE of the delta change in intensity of the fluorescent dye MitoPY1. *Significant differences across time (P < 0.05).
