Abstract

Background: Diabetes patients' quality of life can be severely impacted by diabetic muscle atrophy.Aim: This study aimed to explore the impact of high-intensity exercise (HIE) alongside insulin treatment on muscle atrophy in a rat model of type 1 diabetes mellitus (T1DM).Methodology: Fifty rats were allocated into five groups; Group 1, control sedentary (CS), T1DM was elicited in the rest of the groups by giving them Streptozotocin (STZ) (60 mg/kg), where group 2 (DS) remained sedentary, while groups 3,4,5 were treated with insulin after induction of diabetes. Group 4 (DI+MIE) and 5 (DI+ HIE) underwent moderate and high-intensity exercise, respectively.Results: HIE for 14 days combined with insulin treatment significantly restored muscle strength and mass with a significant modification in the mitophagy-related proteins and fibroblast growth factor 21 (FGF 21) compared to other treated groups.Conclusion: This study concluded that there is a therapeutic role for HIE with insulin against T1DM-induced muscle atrophy.

高强度运动和胰岛素可减轻 1 型糖尿病患者的肌肉萎缩，同时调节骨骼肌中的有丝分裂相关蛋白。

背景：糖尿病肌肉萎缩会严重影响糖尿病患者的生活质量：目的：本研究旨在探讨高强度运动（HIE）和胰岛素治疗对1型糖尿病（T1DM）大鼠肌肉萎缩的影响：将 50 只大鼠分为 5 组：第 1 组为静坐对照组（CS），其余各组通过注射链脲佐菌素（STZ）（60 毫克/千克）诱发 T1DM，第 2 组（DS）保持静坐，第 3、4、5 组在诱发糖尿病后使用胰岛素治疗。第4组（DI+MIE）和第5组（DI+ HIE）分别进行中等强度和高强度运动：结果：与其他治疗组相比，HIE 14 天联合胰岛素治疗可明显恢复肌肉力量和质量，有丝分裂相关蛋白和成纤维细胞生长因子 21（FGF 21）也有显著变化：本研究得出结论：HIE 联合胰岛素对 T1DM 引起的肌肉萎缩有治疗作用。

期刊介绍： Archives of Physiology and Biochemistry: The Journal of Metabolic Diseases is an international peer-reviewed journal which has been relaunched to meet the increasing demand for integrated publication on molecular, biochemical and cellular aspects of metabolic diseases, as well as clinical and therapeutic strategies for their treatment. It publishes full-length original articles, rapid papers, reviews and mini-reviews on selected topics. It is the overall goal of the journal to disseminate novel approaches to an improved understanding of major metabolic disorders. The scope encompasses all topics related to the molecular and cellular pathophysiology of metabolic diseases like obesity, type 2 diabetes and the metabolic syndrome, and their associated complications. Clinical studies are considered as an integral part of the Journal and should be related to one of the following topics: -Dysregulation of hormone receptors and signal transduction -Contribution of gene variants and gene regulatory processes -Impairment of intermediary metabolism at the cellular level -Secretion and metabolism of peptides and other factors that mediate cellular crosstalk -Therapeutic strategies for managing metabolic diseases Special issues dedicated to topics in the field will be published regularly.
