DL (Table 1). Elevated CAT (Figure 1) and SOD (Figure 2) activities, as well as accelerated SH oxidation (Figure 3) were noted in SOL muscle obtained from HFD rats. CAT and SOD activities had been improved in DP when compared with DC (p 0.01; p 0.05, respectively). In addition SOD activity in CP was greater in comparison with CC (p 0.005), and DC (p 0.05). Such alterations have been not observed in EDL muscle (Table two).Nutrients 2013, five Table 1.

In addition, EtP supplementation triggered the elevation of insulin in each groups CP and DP. The concentration of glucose and HbA1c didn’t modify considerably in either group (Table 3).Nutrients 2013, 5 Table three.

Discussion In the current study, 12 weeks of HFD rats treatment brought on a rise in mitochondrial and antioxidant enzymes activities only in SOL muscle, which was associated with SH oxidation. This impact was not abolished by EtP supplementation. Additionally, EtP intake alone for 6 weeks elevated SOD activity and SH oxidation, even though no modification in mitochondrial metabolism was revealed. This observation will not agree with our hypothesis that EtP supplementation would ameliorate impaired by HFD mitochondrial metabolism. Over recent years, several studies have supplied information to indicate that abnormalities in skeletal muscle metabolism are implicated within the improvement of insulin resistance.
