Relative activity levels of citrate synthase (CS) and complex IV (COX IV) after 6-week 3-OBA and ET intervention. A Relative activity of CS after 6-week ET intervention. B Relative activity of CS after 6-week ET intervention and 3-OBA injection. C COX IV relative activity after 6-week ET intervention. D COX IV relative activity after 6-week ET intervention and 3-OBA injection. Measurement data were presented as the mean ± SD. The significance of the difference of the two groups C and H was calculated with the independent samples t test, and the four groups (S, 3, SH, and 3H) were analyzed with the two-way ANOVA. *p < 0.05; **p < 0.01; and ***p < 0.001.
