RESUMO

É genericamente aceite que a idade está associada à imunosenescência. Por outro lado, a actividade física tem sido consistentemente relacionada com estados de humor e afecto positivos motivando, igualmente, ganhos no bem-estar psicológico e no afecto positivo. Carece ainda de fundamentação mais alargada a demonstração de que esses efeitos são extensíveis à pessoa idosa.

O propósito do presente trabalho consiste em averiguar as adaptações crónicas da aptidão física funcional e imunoglobulina A salivar da pessoa idosa a um programa de exercício físico. Simultaneamente, serão analisados os estados de humor dessa população no início e no final do programa.

Participaram 28 sujeitos com idades compreendidas entre os 65 e os 95 anos. O grupo de exercício cumpriu um programa de exercícios físicos durante 16 semanas, com uma frequência de 3 sessões semanais. A análise comparativa dos dados foi efectuada através do recurso ao teste de Wilcoxon.

Verificaram-se alterações positivas na aptidão física funcional que reforçam o princípio da treinabilidade dos idosos. Os dados apontam também para uma melhoria dos estados de humor após o exercício físico e para um efeito crónico imunoprotector.

Palavras-Chave: aptidão física funcional; idosos; IgA; estados emocionais; exercício físico.

 

 

Physical exercise, salivary IgA and mood states of elderly people

ABSTRACT

It is generally accepted that the aging process is associated with immunosenescence. On the other hand, physical activity has been consistently associated with positive states of affection and mood which also implies gains on psychological well-being. However, more studies are needed to support the benefit effect of exercise on specific population groups like the elderly.

The purpose of the present work is to study the functional fitness, mood states and salivary IgA chronic adaptations after a physical exercise program.

28 subjects aged between 65 and 95 years old participated in this study. The experimental group exercised during 16 weeks, 3 times per week. The Wilcoxon test was used to compare the data.

The results showed positive changes on the functional fitness that reinforce the trainability principle of the older person. The data shows also an improvement in mood states and chronic positive effects on salivary IgA after the exercise program. 

Key Words: Functional fitness; elderly; IgA; mood states; physical exercise.
