In the last
years, much research focuses on the possible influence of physical activity on
cognitive decline. Retrospective studies with healthy older people show
that long lasting physical activity may reduce the
risk for this decline.
Prospective
studies supply, in part, results arguing in favor of the efficacy of physical
activity regarding cognition. One of the first meta-analysis was the one of
Colcombe and Kramer. They analyzed the effects of different trainings on
executive, controlled, spatial, and speed tasks. The authors showed a higher
improvement of the physical trainings groups compared to the control groups,
especially in executive tasks.
Until this study,
on the one hand, few other meta-analyses were published, where the results were
either interpreted with caution or positive effects of a physical activity
training compared to a control group could not be shown.
