Effect of swimming exercise on FFA, TG, and oxidative stress parameters in skeletal muscle.

FFA, triglycerides, SOD, GSH-Px, MDA, and 8-OHdG of all rats were measured at the 8th week of the experiment. Results were expressed as mean (M) ± standard deviation (SD) (n = 10). Differences between groups were compared by one-way analysis of variance (ANOVA). We could observe an increase in FFA, TG, MDA, and 8-OHdG and a decrease in SOD and GSH-Px in IR rats, but exercise could decrease the levels of FFA, TG, MDA, and 8-OHdG and increase SOD and GSH-Px in skeletal muscle of rats. ^∗∗ p < 0.01: versus CON group; ^∗ p < 0.05: versus CON group; ^## p < 0.01: versus group HFD group; and ^# p < 0.05: versus group HFD group.
