CAT and hypertensive disorder: These results are corroborated in the soleus muscle (Figure 7b), where a similar behavior in catalase activity was observed in contrast to the EDL muscle, with a notable decrease in catalase activity in the hypertensive group (p ≤ 0.005) in contrast to the control group, and an increase in 1359% in catalase activity in the hypertension + exercise + diazoxide group in comparison with the hypertensive group.
