Abstract
Background: Fetuin-A, as a hepatokine, plays an important role in the regulation of whole-body metabolism, which is increased with chronic diseases. Therefore, the aim of this meta-analysis is to investigate the effect of exercise training on Fetuin-A levels in individuals with metabolic and kidney diseases.
Methods: A systematic search was conducted in PubMed, Web of Science, and Google Scholar databases until November 2022 using the keywords "exercise training" and "Fetuin-A". To determine the effect size, standardized mean difference (SMD) and 95% confidence interval were calculated using CMA2 software. Heterogeneity was evaluated using the I2 test, and publication bias was evaluated by visual interpretation of the funnel plot and Egger's test. The quality of the included studies was evaluated using the PEDRO checklist.
Results: A total of 16 studies including 21 trials arms and 554 subjects with type 2 diabetes, obesity and kidney disease were included in the meta-analysis. Exercise training resulted in a significant decrease in Fetuin-A levels [-0.93 (CI: -1.35 to -0.51) P= 0.001]. There was a high heterogeneity (I2= 89.24, P= 0.001) and also a significant publication bias (P= 0.001). The results of subgroup analysis based on the type of exercise training showed that aerobic training resulted in a significant decrease in Fetuin-A (P= 0.001) while the reduction of this marker with combined training was not significant (P= 0.33).
Conclusion: Exercise training, especially aerobic training, results in a decrease in Fetuin-A levels in metabolic patients, which may be contributed to the beneficial effects of exercise.

Abstract
Background: The purpose of this study was to investigate the impact of aerobic exercise on the function of local renin-angiotensin system and insulin resistance in the Gastrocnemius muscle of type 2 diabetic mice.
Methods: The number of 18 male C57BL/6 mice were divided into two groups: 1. Mice fed with a standard diet for 12 weeks (control group), 2. Mice fed with a high-fat diet for 12 weeks with streptozotocin injection (diabetes group). Diabetic mice were randomly divided into two groups: 1. Diabetes-Sedentary group, 2. Diabetes-exercise group. The mice of the training group exercised on the treadmill for eight weeks and five days/week with an average speed of 19 m/min and for 45 minutes. 24 hours after the last training session, the mice were sacrificed. The Gastrocnemius muscle tissue was extracted and stored in -80°C freezer to measure the expression level of angiotensin 2, Mass receptor, At1 receptor and glucose transporter 4 (Glut 4).
Results: The results showed that the expression of Mass and Glut4 receptor in diabetes-exercise mice was significantly higher than diabetes-sedentary group. Also, the expression of angiotensin 2, HOMA-IR, and fasting glucose in the muscle of diabetes-exercise mice were significantly lower vs. diabetes-sedentary mice. Also, the expression of At1 receptor in the diabetes-exercise group was insignificantly lower than in the diabetes-sedentary group.
Conclusion: The findings of the present study show the important role of exercise in improving the local renin-angiotensin system in skeletal muscle. Eight weeks of aerobic training can reduce muscular insulin resistance and improve type 2 diabetes by decreasing the expression of angiotensin 2, At1 receptor and increasing the Mass receptor.
