Mood, physical working capacity and cognitive performance in the elderly as related to physical activity.

The age-related decline in physical working capacity, cognitive performance, and psychological well-being can presumably be modified by regular physical exercise. The present study comprises 20 men and 20 women with a mean age of 66 years. Half of the participants were randomly assigned to an exercise group, the remaining half to a control group. The members of the exercise group exercised individually through regular walking (three times a week) during a period of three months. The control group performed instead a series of mental tasks with the same regularity. Results showed significant differences in favor of the exercise group on complex tasks at the post-test, whereas only minor differences were found on simple tasks. Mood improvements were uniform, regardless of exercise involvement. The latter can be taken to indicate that exercise is not the most important factor, instead social context and regular contacts with other people may be equally important for elderly individuals.
