Resumo
O objetivo desta dissertação passa por analisar a associação entre o exercício
físico, a atividade física, o comportamento sedentário, no funcionamento cognitivo, do
idoso.
Este documento tem 2 estudos.
1) Uma revisão rápida e sistemática sobre a associação entre o exercício físico
e o funcionamento cognitivo, do idoso; 2) estudo observacional sobre a associação entre
a atividade física, o comportamento sedentário e o funcionamento cognitivo, numa
amostra de idosos (n=85) que participou numa intervenção com base na atividade de
canto e que foi possível recolher dados de atividade física e comportamento sedentário,
através de acelerometria (Actigraph wGT3x-BT) e dados relativos ao funcionamento
cognitivo por um teste de rastreio cognitivo (Montreal Cognitive Assessment Test).
Na revisão rápida e sistemática de literatura foram incluídos, para síntese
qualitativa, 4 estudos. Todos os estudos apresentaram associações positivas entre as
variáveis de exercício físico e o funcionamento cognitivo, ou seja, os participantes dos
grupos que pertenciam à intervenção, apresentaram melhorias na sua função cognitiva
após o período de intervenção, comparativamente ao grupo de controlo.
No estudo observacional foi possível constatar que a atividade física moderada
a vigorosa prediz o funcionamento cognitivo, controlando para a idade. Estes resultados
vão de encontro à literatura científica recente que demonstra a capacidade da
intensidade da atividade física desempenhada diariamente, pelo idoso ter mais efeitos
protetores, em relação aos efeitos do declínio cognitivo, do que a quantidade que ele
realiza. Passa por esta linha teórica estudada por esses autores que os resultados do
estudo observacional incluído nesta dissertação, se encontra.
É de mencionar a necessidade de novos estudos que aprofundem a forma como
se pode criar estratégias de curta duração e mais intensas, para impedir os efeitos
degenerativos, do declínio cognitivo.
The objective of this dissertation is to analyze the association between physical exercise, physical activity, sedentary behavior, in the elderly's cognitive functioning. This document has 2 studies. 1) A quick and systematic review of the association between physical exercise and cognitive functioning in the elderly; 2) observational study on the association between physical activity, sedentary behavior and cognitive functioning, in a sample of the elderly (n = 85) who participated in an intervention based on singing activity and that it was possible to collect data on physical activity and behavior sedentary, through accelerometry (Actigraph wGT3x-BT) and data related to cognitive functioning by a cognitive screening test (Montreal Cognitive Assessment Test). In the rapid and systematic review of the literature, 4 studies were included for qualitative synthesis. All studies showed positive associations between physical exercise variables and cognitive functioning, that is, participants in the groups that belonged to the intervention, showed improvements in their cognitive function after the intervention period, compared to the control group. The observational study showed that moderate to vigorous physical activity predicts cognitive functioning, controlling for age. These results are in line with recent scientific literature that demonstrates the capacity of the intensity of physical activity performed daily, for the elderly to have more protective effects, in relation to the effects of cognitive decline, than the amount that they perform. It goes through this theoretical line studied by these authors that the results of the observational study included in this dissertation are found. It is worth mentioning the need for further studies to deepen the way in which short and more intense strategies can be created to prevent the degenerative effects of cognitive decline.
