Figure 5.

Enzymatic activity of (a) superoxide dismutase (SOD), (b) catalase (CAT), and (c) glutathione peroxidase (GPx) in gastrocnemius muscle in control rats (Ctr), rats that only underwent a resistance exercise session (RE), and rats that were submitted to 4J LLLT irradiations prior to a resistance exercise session (4J). (d) Total antioxidant capacity of gastrocnemius muscle by ferric reduction ability power assay (FRAP). Data are representative of samples collected instantly and 24 h after exercise. ANOVA two-way and Bonferroni post hoc tests were used for multiple comparisons. ^∗p < 0.05 versus Ctr group; ^#p < 0.05 versus instant time. Number of animals for each experiment is shown inside the bars.
