RESUMENEl objetivo de esta investigación fue investigar las relaciones entre funciones ejecutivas y capacidad funcional y determinar los predictores motores de la deficiencia de las funciones ejecutivas en ancianos con enfermedad de Alzheimer (EA). 24 ancianos con EA fueron evaluados para estimar las funciones ejecutivas y los predictores motores. Se utilizó el análisis estadístico descriptivo, correlación de Pearson y regresión lineal múltiple. Las funciones ejecutivas se relacionaron con la flexibilidad (r = 0.54), equilibrio (r = 0.48), agilidad y movilidad (r = -0.41). El análisis de regresión apuntó equilibrio y flexibilidad como predictores motores de la deficiencia de las funciones ejecutivas. El prejuicio del equilibrio y la flexibilidad pueden predecir los prejuicios en funciones ejecutivas de ancianos con EA.

ABSTRACTThe objective of this paper was investigate the relationship between executive function and functional capacity and determine predictors engines for decline of executive functions in elderly patients with AD. A total of 24 elderly patients with EA were evaluated to estimate predictors
-The mistaken use of biostatistics in scientific research involves methodological errors both in the research itself as in its analyses. Among these, the lack of sample size calculation, considered essential for validation and credibility of results, is often found. The aim of the study was to determine how often sample size calculation is used in articles published in Physical Education national journals. The study included only national scientific journals ranked as A1 and B2 by the Coordination of Improvement of Higher Education Personnel (CAPES), which analyzed only articles available in full and published in the period from 2010 to 2012. Review articles, letter to the editor, points of view and original articles that did not perform any statistical analysis were excluded. Approximately 15 % of articles analyzed performed sample size calculation and no difference between these proportions over the years were identified. Differences between Physical Education subareas (education, health and sport) were observed, being lower in sport (p = 0.001) compared to other subareas. Journals classified as B2 showed higher use of sample size calculation in relation to those classified as B1 (p = 0.013) and A2 (p = 0.007). The use of sample size calculation in scientific research published in Physical Education national journals in the period from 2010 to 2012 was not satisfactory, especially in sport subarea. Moreover, no evolution on the use of sample size calculation over the years analyzed was observed. Key words: Physical education; Sample size; Statistics.

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.
