Introduction: Aerobic exercise training (AT) in type 2 diabetic patients reduces cardiovascular disease (CVD) risks, such as an impairment of NO-derived vasodilation mediated by obese and hyperinsulinemia. Musclin is a muscle-derived myokine and binds to natriuretic peptide receptor-C (NPR-C). Elevation of circulating musclin level deteriorates of insulin resistance. Furthermore, musclin-induced vasocontraction mediated by NPR-C leads to increase in blood pressures. However, the effect of AT on muscle-derived musclin secretion in type 2 diabetes remains unclear. Hypothesis: This study aimed to clarify whether AT-induced attenuations of muscle-derived musclin secretion and arterial NPR-C expression levels are related to reduction of CVD risks in type 2 diabetes rats. Methods: Twenty 20-week-old male type 2 diabetic (OLETF) rats were randomly divided into two groups; 8-week sedentary control and aerobic exercise training (treadmill running for 60min at 25m/min, 5days/week) (n=7 each group) and seven male LETO rats used as healthy sedentary control. After 8 weeks, we measured carotid-femoral pulse wave velocity (cfPWV, an index of arterial stiffness), QUICKI (an index of insulin sensitivity), plasma and muscle musclin levels and GLUT4 translocation levels, arterial NPR-C protein expression. Results: In sedentary diabetic rats, cfPWV, serum insulin and muscle musclin levels, and arterial NPR-C protein expression increased, and QUICKI decreased as compared to healthy sedentary rats (each p<0.05). However, no significant circulating musclin level between sedentary and exercised diabetic rats was observed. In contrast, aerobic exercise training in the diabetic rats induced elevation of QUICKI and reduction of cfPWV, serum insulin, muscle musclin, and arterial NPR-C levels (each p<0.05). NPR-C protein level was positively correlated with cfPWV (r=0.43, p=0.09). Additionally, muscle musclin levels was significantly negatively correlated with muscle GLUT4 translocation (r=-0.78, p<0.01) and QUICKI (r=-0.82, p<0.01). Conclusions: These results suggest that attenuation of arterial NPR-C expression and muscle-derived musclin secretion is related to reductions of arterial stiffness and hyperinsulinemia by AT in type 2 diabetic rats.

Introduction: Type 2 diabetes is associated with elevated C-reactive protein levels (CRP), which is an independent risk factor for cardiovascular disease. Aerobic exercise training especially with weight/adiposity reduction has been shown to improve CRP, however few studies have evaluated the effect of other exercise training modalities (aerobic, resistance or combination training) on CRP in individuals with type 2 diabetes. Hypothesis: We hypothesize that combination training will improve CRP to a greater extent than other modalities of exercise training, and change in CRP levels will be associated with changes in weight and adiposity. Methods: The present study is a secondary analysis of the Health Benefits of Aerobic and Resistance Training in Individuals with Type 2 Diabetes (HART-D) study. Participants (n=204) were randomized to aerobic exercise (aerobic), resistance exercise (resistance) or a combination of both (combination) for nine months. Results: Baseline CRP was correlated with fat mass, waist circumference, BMI, and inversely correlated with VO2 peak (p<0.05). CRP was not reduced in the aerobic (0.16 mg•L-1, 95% CI: -1.0, 1.3), resistance (-0.03 mg•L-1, 95% CI: -1.1, 1.0) or combination (-0.49 mg•L-1, 95% CI: -1.5 to 0.6) groups compared to control (0.35 mg•L-1, 95% CI: -1.0, 1.7). Change in CRP was associated with change in fasting glucose (r=0.20, p= 0.009), glycated hemoglobin (HbA1C) (r=0.21 p=0.005), and fat mass (r=0.19, p=0.016), but not change in fitness or weight (p > 0.05). Conclusions: In conclusion, aerobic, resistance or a combination of both did not reduce CRP levels in individuals with type 2 diabetes. However, exercise related improvements in HbA1C, fasting glucose, and fat mass were associated with reductions in CRP.

Long Term Treatment

We investigated the effect of long-term treatment (6 wk) with selenium and vitamin E, in combination with aerobic exercise training, on malondialdehyde (MDA), oxidized low-density lipoprotein (ox-LDL), and glutathione peroxi-dase (GPx) in STZ-induced diabetic rats. The rats were assigned randomly to one of three treatment groups (n = 12 per group): 1) exercise group (EX), 2) selenium/vitamin E/exercise group (SVE), and 3) selenium/vitamin E group (SV). To estimate the acute effect of exercise, a 30-min endurance exercise was used. The MDA concentration was significantly lower in the SVE. The ox-LDL was significantly lower in the SVE and SV. The hepatic concentrations of selenium and vitamin E were significantly higher in the SVE. These results indicate that the increase in MDA is mildly attenuated in rats that were aerobically trained. Moreover, the joint administration of selenium and vitamin E with or without exercise training reduces the levels of ox-LDL.
