| Abstract | Increased levels of oxidative stress and inflammation have been linked to the progression of chronic kidney disease. To reduce oxidative stress and inflammation related to chronic kidney disease, chronic aerobic exercise is often recommended. Data suggests high intensity interval training may be more beneficial than traditional aerobic exercise. However, appraisals of differing modes of exercise, along with explanations of mechanisms responsible for observed effects, are lacking. This study assessed effects of eight weeks of high intensity interval training (85% VO2max), versus low intensity exercise (45-50% VO2max) and sedentary behaviour, in an animal model of early-stage chronic kidney disease. We examined kidney-specific mRNA expression of genes related to endogenous antioxidant enzyme activity (glutathione peroxidase 1; Gpx1, superoxide dismutase 1; Sod1, and catalase; Cat) and inflammation (kidney injury molecule 1; Kim1 and tumour necrosis factor receptor super family 1b; Tnfrsf1b), as well as plasma F2-isoprostanes, a marker of lipid peroxidation. Compared to sedentary behaviour, high intensity interval training resulted in increased mRNA expression of Sod1 (p=0.01) and Cat (p<0.001). Compared to low intensity exercise, high intensity interval training resulted in increased mRNA expression of Cat (p<0.001) and Tnfrsf1b (p=0.047). In this study, high intensity interval training was superior to sedentary behaviour and low intensity exercise as high intensity interval training beneficially influenced expression of genes related to endogenous antioxidant enzyme activity and inflammation. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
