PURPOSE: The purpose of this study was to investigate the effect of resistance ladder exercise on myocardial inflammatory cytokines and extracellular signal regulated kinase (ERK)1/2 expression in type 2 diabetic rats.METHODS: A total of 21 8-week-old male Long Evans Tokushima Otsuka (LETO) and Otsuka Long Evans Tokushima Fatty (OLETF) rats were divided into three groups: LETO group (CON, n=7), OLETF group (DM, n=7), and resistance exercise group (DM+EXE, n=7). Resistance exercise referred to a climbing exercise on a slope. The rats performed this exercise 3 full d per week, for 8 week. The expression of myocardial inflammatory cytokines and ERK1/2 was analyzed via western blotting after 8 week of exercise intervention.RESULTS: After 8 weeks of resistance exercise for the management of type 2 diabetes, the production of anti-inflammatory factor Interleukin (IL)-10 in the myocardium increased. This inhibited the production of pro-inflammatory factors IL-6 and tumor necrosis factor-alpha. However, resistance exercise did not affect the expression of ERK1 and ERK2, which are apoptosis regulatory proteins.CONCLUSIONS: In type 2 diabetes, resistance exercise is thought to be effective in reducing inflammatory factors by mediating cytokines. Although the effects of resistance ladder exercise were confirmed, further studies on a variety of exercise types and intensities should be conducted to prevent and improve the conditions of those with diabetes.

Diagnosis of rare incurable diseases is important. Specific evaluation methods and standards for sarcopenia differ according to each sarcopenia-related medical association. This study aimed to identify the tools that are currently used to diagnose sarcopenia and to systematically review various interventions for sarcopenia. We intended to provide basic information to help establish standard diagnostic and therapeutic methods for sarcopenia. We collected and analyzed published journal articles, including gray literature and dissertations, from 11 domestic and international databases. The search terms were “sarcopenia/sarcopenic”, “combined (complex/circuit) exercise”, “resistance (muscle) exercise”, and “aerobic exercise”. The tools used for sarcopenia diagnosis were inconsistent across the studies. Circuit exercise combined with aerobic exercise and strength training was the most common intervention method, followed by strength training and aerobic exercise. We identified several diagnostic and evaluation criteria across the articles. Essentially, this systematic review confirms the importance of diagnostic criteria for sarcopenia and compares interventions. Hopefully, the criteria for the diagnosis and evaluation of sarcopenia will become clear in the future. In addition, the results of this study may provide basic information for rehabilitation treatment for rare and incurable diseases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
