Figure 3.

Superoxide dismutase and Catalase activity. In the Figure is shown a representative example of enzyme activities. The activity of Superoxide dismutase showed similar level on myoblasts with decreased ${\text{O}}_2^{•-}$ production (empty bars) while it was reduced in myoblasts showing increased ${\text{O}}_2^{•-}$ production (dotted bars) with respect to PRE-Ex (^*p ≤ 0.05). The Catalase activity was similar among the PRE-Ex and POST-Ex cells, despite the ${\text{O}}_2^{•-}$ production.
