    Diabetes is a metabolic disorder characterised by hyperglycaemia. The diabetic heart becomes more susceptible to ischemic injury. Although exercise induces a cardioprotective phenotype, the determination of accurate protocol is crucial. We compared two different exercise intensities in the diabetes model and evaluated the role of myokines in exercise-induced cardioprotection. Male, adult, Wistar albino rats were used (n = 20 each). First, animals were divided into two groups: Non-Diabetic (ND), Diabetic (DM); then groups were further divided into subgroups: Sedentary (S), Training-1 (T1 =10 m/min, 00 inclination), and Training-2 (T2 = 20 m/min, 100 inclination). Diabetes was induced by streptozotocin (60 mg/kg; i.p.). Animals exercised on a treadmill 5 days/a week for 6 weeks. Then, hearts were attached to the Langendorff apparatus and baseline functional parameters were measured. After 30'/120'I/R protocol, infarct size was evaluated with tetrazolium chloride staining. Interleukin-6, FNDC5, and myonectin levels were measured both in the soleus and the left ventricle. We observed cardiac hypertrophy and impaired baseline LV function in diabetes. Infarct size was significantly larger in diabetics and only T1 decreased the infarct size whereas T2 further aggravated it. Moreover, post-ischemic recovery was worst in diabetic-T2 group. Irisin and myonectin levels were decreased in the soleus muscle of diabetic animals. T1 increased the myonectin levels in the left ventricle of non-diabetics, and this effect was blunted in diabetic-T1 animals. As a conclusion, light-intensity exercise is a better approach to prevent ischemic damage in diabetes besides moderate intensity may be hazardous in diabetic population.

    Objectives: Exercise capacity is related to both morbidity and mortality in patients with type 2 diabetes (T2DM). The aim of this study was to investigate the relationship between subclinical inflammation level, exercise capacity, muscle oxygenation and quality of life in T2DM. Methods: This study includes 28 patients with T2DM (mean age, 51.5 +/- 5.0 years; male-to-female ratio, 6:22). Exercise capacity was evaluated using an incremental symptom-limited maximal exercise test on a bicycle ergometer. Muscle oxygenation was investigated using a wearable lactate-measuring device. Diabetes-specific quality of life was assessed using the Diabetes Quality of Life Questionnaire (DQOL). Subclinical inflammation was assessed using C-reactive protein (CRP) levels. Results: CRPlevelwasnegatively correlatedwith peakworkload during the test (r=-0.588, p=0.002), muscle oxygenation (r=-0.465, p= 0.019) and the psychological impact of treatment subscale of the DQOL (r= e0.540, p=0.017), and positively correlated with body mass index (r=0.519, p=0.008), waist circumference (r=0.426, p=0.038) and fat percentage (r=0.573, p=0.004). Therewasnocorrelation betweenCRPand fasting blood glucose or glycated hemoglobin level (p>0.05). Peakworkloadwas inversely related to fat percentage (r=-0.467, p=0.016) and the DQOLworry about the future impact of diabetes subscale (r=-0.501, p=0.021). Conclusions: In our study, subclinical inflammation negatively affected muscle oxygenation, exercise capacity and quality of life independently of glycemic indicators. Our findings suggest that the degree of glycemic control is insufficient to explain lower exercise capacity. Further studies are needed to investigate subclinical inflammation-reducing interventions in T2DM. (C) 2020 Canadian Diabetes Association.
