Introdução: Vários estudos apontam no sentido de um papel significativo da
actividade física no envelhecimento. Procurou-se avaliar este papel de forma
objectiva, bem como compará-lo com o papel da reserva cognitiva.
Metodologia: Recorreu-se a uma amostra de conveniência de 39 sujeitos,
saudáveis, com idade entre os 65 e os 86 anos. Para além de uma entrevista
clínica breve, aplicou-se o CRIq, o Digit-Symbol, o Digit Span Inverso e o
Stroop. Recorreu-se ao coeficiente de correlação de Pearson e a regressões
lineares.
Resultados: Não se observaram correlações significativas entre os resultados
nas provas que avaliavam os mecanismos cognitivos e a actividade física. A
reserva cognitiva foi o único contribuidor para a cognição.
Conclusões: Sugerem-se, para estudos futuros, medidas mais objectivas de
actividade física, bem como recorrer a uma amostra mais ampla e
representativa da população.
Introduction: Several studies point towards physical activity having a positve and meaningful role in aging. This study aimed to assess this role objectively, as well as compare its contribution to aging with cognitive reserve’s role. Method: Our convenience sample was composed of 39 healthy subjects, with ages between 65 and 86. After a brief clinical interview, ch subject completed the CRIq, the Digit Symbol Substitution test, inverse Digit-Span and Stroop Test. We used Pearson’s correlation coeficiente and multiple regression analysis. Results: No significative correlations were found between any od the cogntiive measures and the physical activity measures. Cognitive reserve was, on this study, the only contributor to cognition. Conclusions: For future studies, we suggest more objective measures for physical acvitiy, as well was a wider and more representative sample.
