Effects of weight training on cognitive functions in elderly with Alzheimer's disease

Efeitos do treinamento com pesos nas funções cognitivas de idosos com doença de Alzheimer

ABSTRACT

Deterioration in cognitive functions is characteristic in Alzheimer's disease (AD) and may be associated with decline in daily living activities with consequent reduced quality of life.

Objective:

To analyze weight training effects on cognitive functions in elderly with AD. Subjects: 34 elderly with AD were allocated into two groups: Training Group (TG) and Social Gathering Group (SGG).

Methods:

Global cognitive status was determined using the Mini-Mental State Exam. Specific cognitive functions were measured using the Brief Cognitive Battery, Clock Drawing Test and Verbal Fluency Test. The protocols were performed three times a week, one hour per session. The weight training protocol consisted of three sets of 20 repetitions, with two minutes of rest between sets and exercises. The activities proposed for the SGG were not systematized and aimed at promoting social interaction among patients. The statistical analyses were performed with the U Mann Whitney and Wilcoxon tests for group comparisons. All analyses were considered statistically significant at a p-value of 0.05.

Results:

There were no significant differences associated to the effects of the practice of weight training on cognition in AD patients.

Conclusion:

In this study, no improvement in cognitive functions was evident in elderly with AD who followed a low intensity resistance exercise protocol. Thus, future studies could evaluate the effect of more intense exercise programs.

Key words:
cognition; Alzheimer's disease; resistance training

RESUMO.

A deterioração das funções cognitivas é característica na doença de Alzheimer (DA) e se relaciona com uma pior realização das atividades de vida diária levando a uma pior qualidade de vida.

Objetivo:

Analisar os efeitos de um programa de treinamento com pesos nas funções cognitivas de idosos com DA. Sujeitos: 34 idosos com DA foram alocados em dois grupos: Grupo Treinamento (GT) e Grupo de Convívio Social (GCS).

Métodos:

Para caracterização do perfil cognitivo global utilizou-se o Mini-Exame de Estado Mental. Para a mensuração das funções cognitivas foram utilizadas: Bateria Cognitiva Breve, Teste do Desenho do Relógio e teste de Fluência Verbal. Os protocolos oferecidos foram realizados três vezes na semana, durante uma hora. O protocolo de treinamento do GT consistiu em realizar três séries de 20 repetições para cada exercício, com dois minutos de intervalo entre séries e entre exercícios. As atividades propostas para o GCS não foram sistematizadas e tiveram por objetivo promover uma socialização dos pacientes. A análise estatística consistiu na utilização dos testes U Mann Whitney e Wilcoxon para comparação intra e entre grupos. Adotou-se nível de significância de 5% para todas as análises.

Resultados:

Não foram evidenciadas diferenças significativas relacionadas aos efeitos da prática do treinamento com pesos na cognição de idosos com DA.

Conclusão:

Neste estudo não houve melhora nas funções cognitivas em idosos com DA que realizaram um protocolo de exercícios resistidos de intensidade leve. Assim, estudos futuros poderiam verificar o efeito de exercícios mais intensos.
