A scientific study on diets, physical exercises,and morphological aspects of Sarcopenia: a description of methodological approaches

ABSTRACT

Introduction: The aging process is characterized by several morphological and functional changes associatedwith reduced functional capacity of organs. One of them is sarcopenia, a progressive loss of muscle massprocess associated with a reduction in the number and size of muscle fibers. The morphological evidence ofskeletal muscle sarcopenia is a parameter for assessing the degree of loss of function. Objective: Consideringthe importance of such evidence on the cell morphology on sarcopenia, held a retrospective literature reviewto selected articles in Medline, Lilacs, SciELO and PubMed, from 2000 to 2010, identifying the design ofstudies related to diet, exercise and morphology of skeletal muscle in sarcopenia published in the last 10 years.Methods: After selection by the proposed inclusion criteria, were analyzed for the journal title and the article,year of publication, country of origin, type of methodology used, type and authorship, and research subjects.Results: During the period from 2000 to 2010, there were 57 papers, only 8 described morphology of skeletalmuscle-related sarcopenia, diet and exercise. In all searches were observed the quantitative data analysis, andmethodological approaches observed were only two literature review and experimental study. Conclusion:The publications are characterized by multiple authors are published in journals in different fields (nutrition,age, morphology, biology and experimental gerontology).
