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.
