Aims Resistin is secreted by adipose tissue and could be the link between diabetes and infertility. This study aimed to investigate the alteration of resistin following aerobic exercise training in diabetic rats and its possible interaction with sperm parameters. Methods & Materials In this experimental study, 30 male Wistar rats (age: 56 days, weight: 200-250g) were randomly divided equally into three groups of healthy control, diabetic control, and diabetic aerobic exercises. Diabetes was induced with a unique intraperitoneal injection (65 mg/kg body weight) of streptozotocin. Seven days after the injection and after 12 hours of fasting, the animals with blood glucose levels of ≥250 mg/dL were considered diabetic. Seven days after the induction of diabetes, the animals in the exercise group were subjected to progressive aerobic training (treadmill running for 1 h, 27 m/min, 5 d/wk). After 10 weeks of exercise, the sperm quality and resistin concentrations were measured. The obtained data were compared using Analysis of Variance (ANOVA) (P<0.05). Findings The induction of diabetes significantly decreased sperm count (P=0.001), motility (P=0.001), viability (P=0.001), and morphology (P=0.01). The sperm parameters, such as count (P=0.03) and viability (P=0.002) were significantly higher in the diabetic exercise group, compared to the diabetic sedentary group. No significant changes were found in resistin levels between diabetic exercise and diabetic sedentary groups (P=0.40). Conclusion The collected results indicated that the 10-week aerobic training regimen improved sperm quality, independent of changes in resistin levels, in type 2 diabetes mellitus rat models.

Abstract Objective We aimed to evaluate the effect of 12-week aerobic exercise training on fetuin-A levels in type 2 diabetes mellitus and examine the relationships between fetuin-A and adipocytokine levels and cardiovascular risk factors. Methods The study included 32 patients with type 2 diabetes mellitus who were assigned to an exercise or a control group. The exercise group underwent 12 weeks of exercise (consisting of a 5-min warm-up, 60-min aerobic bicycle training performed at 70% of the maximal heart rate, a cool-down period, 5 times/week). Adiponectin, resistin, and fetuin-A serum levels were measured using enzyme-linked immunosorbent assay. Leptin serum levels were measured by a radioimmunoassay. Results Exercise for 12 weeks significantly reduced serum fetuin-A (643.1±109.4 to 448.7±92.5 μg/mL, P<0.05), leptin (11.9±7.2 to 8.6±5.7 ng/dL, P<0.05), and resistin (3.2±1.5 to 2.2±1.4 ng/mL, P<0.05) levels, but increased adiponectin (6.9±1.9 to 8.1±1.7 µg/mL, P<0.05) levels. In the exercise group, Δfetuin-A positively correlated with differences in weight (r=0.654, P=0.046), body mass index (r=0.725, P=0.002), waist circumference (r=0.898, P=0.013), and adiponectin levels (r=0.662, P=0.035). Conclusions Aerobic exercise significantly decreased serum fetuin-A levels in type 2 diabetes mellitus, which can be attributed to weight loss and related to increased adiponectin levels.

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.

BACKGROUND Physical exercise is strongly associated with the release of β-endorphin. It is assumed that the type and intensity of physical exercise contributes to the release of β-endorphin. This study aimed to compare levels of β-endorphin in brain tissue in response to aerobic and anaerobic physical exercise. METHODS This study was an experimental laboratory study using 35 male Wistar rats divided into one control group and two physical exercise treatment groups: aerobic and anaerobic. Physical exercise was conducted on an animal treadmill running at aspeed of 20 m/min for 30 min of aerobic exercise and 35 m/min with 1-min intervals every 5 min for 20 min for anaerobic exercises. Each aerobic and anaerobic exercise group was furtherly classified into three subgroups (1×/week, 3×/week, and 7×/week). β-endorphin levels were determined using enzyme-linked immunosorbent assay. The data were analyzed using independent t-test and one-way analysis of variance. RESULTS The highest mean of β-endorphin level was found in the weekly exercise (54.45 [1.41] pg/ml) of aerobic exercise group and daily exercise (70.50 [11.67] pg/ml) of anaerobic exercise group. Mean of β-endorphin level in control group was 33.34 (3.54) pg/ml. A significant increased of β-endorphin mean level (p<0.001) was found in all aerobic and anaerobic exercise groups except the aerobic exercise 7×/week group(37.37 [6.30] pg/ml) compared to control. CONCLUSIONS Both aerobic and anaerobic physical exercise conducted for 6 weeks could increase the level of β-endorphin in brain tissue.

Objective The clinical manifestations of diabetic cognitive dysfunction are decreased visual spatial ability, executive dysfunction, mental activity speed and attention, and decreased abstract logical reasoning. Cognitive dysfunction is irreversible. Timely and accurate assessment and diagnosis, early detection and intervention to delay disease progression are particularly critical. The Cognitive Assessment Scale plays an important role in screening for cognitive dysfunction in diabetes. To observe the effects of motor functional therapy on cognitive impairment and blood glucose, blood lipids, body weight, body composition, and maximal oxygen uptake in patients with type 2 diabetes. Methods A total of 63 elderly patients with type 2 diabetes mellitus in Chengdu community aged ≥65 years and educated for ≥12 years were enrolled in the motor function therapy group according to the simple mental state examination (MMSE) score (diabetes cognitive impairment, MMSE total score) ≥ 20 points, aerobic exercise group, n = 21) and functional function therapy group (diabetes cognitive impairment, MMSE total score ≥ 20 points, resistance exercise group, n = 21). The adult community of diabetes in Chengdu (normal cognitive function) with age ≥ 65 years, education time ≥ 12 years, and MMSE total score ≥ 24 points was used as the control group (n=21). Montreal Cognitive Assessment Scale (MOCA): MOCA is an assessment tool developed by Nasreddine and clinically proven to be used for rapid screening of MCI. There were no statistical differences in baseline data (age, gender, and hypertension incidence) among the 3 groups of patients. The LOTCA scale was used to evaluate the cognitive function of the subjects and to compare between groups. Sixty-three patients with type 2 diabetes were randomly divided into aerobic exercise intensity group (50% VO2max) (n=21), resistance exercise intensity group and control group (n=21). Both the aerobic exercise group and the resistance exercise group underwent a 12-week moderate-intensity exercise three times a week. The resistance middle strength group was trained 2 groups each time, each group was 25 minutes, the group rested for 5 minutes, 55 minutes in total, and the aerobic medium intensity group continued to exercise for 55 minutes. All patients underwent fasting blood glucose (FPG), glycosylated hemoglobin (HbA1c), total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL), body weight, and fat weight (FW) before and after training. , lean body mass (LBM), maximal oxygen uptake (VO2max) determination; measure the energy expenditure of word movement and the total energy expenditure of the entire exercise process. Results There were no significant differences among the three groups before the test (P>0.05). All the indexes of the medium-intensity resistance exercise group and the medium-intensity aerobic exercise group were significantly different from the control group (P<0.05). After the MOCA score test There was an improvement in the score before the trial, and the total score of LOTCA was significantly different among the three groups. In addition to perceptual sub-items (item identification), the aerobic exercise group and the resistance exercise group LOTCA scale in perceptual sub-projects (incomplete object recognition), visual motion organization and its sub-projects (copying two-dimensional graphics, building blocks) The design and puzzle) project scores were higher than before the test, close to the control group score. The scores of the two groups of exercise therapy in the thinking operation and its sub-projects (Riska organized shape classification, picture arrangement B and geometric reasoning) and attention-focused items were lower than the control group. Compared with the resistance exercise, there was a significant difference in the maximum oxygen uptake between aerobic exercise and resistance exercise (P<0.05). Compared with the total exercise energy consumption in the first 6 weeks, the aerobic exercise group was superior to the resistance exercise group. The total exercise energy expenditure was compared in the last 6 weeks, and the resistance exercise group was superior to the aerobic exercise group. Conclusions Elderly patients with type 2 diabetes may have cognitive impairment earlier. In the absence of differences in exercise, the aerobic exercise group and the resistance exercise group improve cognitive impairment, blood sugar, blood fat, body weight, and body composition in patients with type 2 diabetes. There is no significant difference. Compared with MMSE, LOTCA has the advantage of identifying early cognitive impairment in elderly patients with type 2 diabetes and distinguishing the severity of the damage.

Background: The use of aerobic exercise as a form of glycemic control in type 2 diabetes mellitus has been well documented in the literatures. High blood pressure has been shown to be one of the sequelae of type 2 diabetes mellitus. Determination of mode of exercises for glycemic control that will not adversely affect the cardiovascular indices of type 2 diabetes mellitus subjects is highly indicated. Objective: The purpose of this study was to determine the acute cardiovascular responses of type 2 diabetes mellitus subjects to continuous and intermittent modes of exercises. Results: There was statistical significant difference in heart rate of both groups. Continuous mode of exercise elicited no statistical difference in SBP and DBP but there was statistical significant difference in SBP in intermittent exercise group with no statistical significant in their DBP. Cross comparison of pre and post cardiovascular indices showed that there were statistical significant differences in SBP (F=0.710, P>0.05) and DBP (F=1.397, P>0.05). Conclusion: Cardiovascular responses of type 2 diabetes mellitus subjects were higher in intermittent exercise group compared with the continuous exercise group.

Abstract Introduction Left atrial (LA) strain has been shown to be an independent predictor of cardiovascular events in many conditions and superior to conventional measures of LA function (LA volumes and emptying fraction). The effects of low-energy diet or exercise on cardiovascular function in younger adults with type 2 diabetes (DIASTOLIC) study has previously demonstrated an improvement in left ventricle peak early diastolic strain rate in response to aerobic exercise in patients with type-2 diabetes (T2D). However, the effect of lifestyle intervention on LA function, assessed by cardiac magnetic resonance (CMR) imaging, is unknown. Methods The DIASTOLIC study was a prospective, randomised, open-label, blind endpoint trial, that randomised 90 obese participants with T2D (aged 18–65 years) to a 12-week intervention of: (i) routine care, (ii) aerobic exercise training, or (iii) low energy (≈810kcal/day) meal replacement plan (MRP). CMR was performed at baseline and week-12. Images were analysed using Medis v3.1. LA strain (LAS) was assessed using Feature Tracking (QStrain v2.0), corresponding to LA reservoir (LAS-r), conduit (LAS-cd), and booster pump (LAS-bp) using 4- and 2-chamber standard steady-state free precession cine images, and average values calculated. LA emptying fraction (LAEF) was calculated using biplane area-length method (QMass v8.1) for total, passive and active EF. Results 73 participants with T2D completed the trial and had analysable LA images (28 routine care, 22 exercise and 23 MRP). There was no significant change in CMR measured standard LA volumetric function (LAV/LAEF) and echocardiogram measured LV filling pressures (E/e') in any groups. The routine care arm showed no significant change in body mass index (BMI) or LAS (see Table). In the MRP group, there were significant reductions in BMI (4.8 kg/m2), mean systolic blood pressure (SBP) (13mmHg), and a significant increase in LAS-r and LAS-bp (29.9±7.0 to 32.3±7.0,p=0.036 and 14.6±5.3 to 17.2±3.7,p=0.034). The exercise arm showed a small reduction in BMI (0.8kg/m2), with no significant change in BP or LAS. Conclusion There was significant improvement in LAS post-lifestyle intervention in young adults with T2D, despite no change in volumetric measurements. MRP led to weight loss and improved SBP, with associated improved LA filling and contraction. FUNDunding Acknowledgement Type of funding sources: Public grant(s) – National budget only.

Abstract Aerobic exercise training is a potent intervention for the treatment and prevention of age-related disease, such as heart disease, obesity, and Type 2 Diabetes. Insulin resistance, a hallmark of Type 2 Diabetes, is reversed in response to aerobic exercise training. However, the effect of aerobic exercise training on glucagon sensitivity is unclear. Glucagon signaling at the liver promotes fatty acid oxidation, inhibits De novo lipogenesis, and activates AMP Kinase, a key mediator of healthy aging. Like humans, aging in mice age leads to a decline in physical and metabolic function. To understand the role of glucagon signaling in exercise-induced improvements in physical and metabolic function in the mouse, we implemented a 16-week aerobic exercise training protocol in young and aged mice. 16 weeks of exercise training initiated at 6 months of age increased markers of physical function (P&lt;0.01) and attenuated age-related weight gain (P&lt;0.05) and fat mass (P&lt;0.0001). Additionally, exercise training improved glucose clearance (P&lt;0.01), enhanced glucose-stimulated insulin secretion (P&lt;0.01) and decreased hepatic lipid accumulation (P&lt;0.05). Importantly, exercise training decreased hypoglycemia stimulated glucagon secretion (P&lt;0.01), with no effect on hepatic glucagon receptor mRNA expression or serum glucagon. Thus, we propose that aerobic exercise training enhances glucagon sensitivity at the liver, implicating glucagon as a potential mediator of exercise-induced improvements in aging. Studies initiating the same aerobic exercise training intervention at 18 months of age in the mouse are currently underway to establish the role of glucagon receptor signaling in exercise-induced improvements in aging.
