Background: A recent clinical trial by the KU ADC indicated
that increasing fitness predicted better cognition in active
healthy older adults. Maximizing an individual’s cardiorespiratory
fitness was the most important therapeutic target for
achieving cognitive benefit. We use data from a satellite
project in San Jose Costa Rica to examine the role of fitness
on cognitive performance in urban dwelling Latin Americans.
Low and middle income nations will experience an unprecedented
growth of the elderly population and subsequent
increase in age-related neurological disorders that requires
effective strategies for promoting healthy brain aging and
the prevention of Alzheimer’s disease. Methods: By extending
our standardized cognitive and physical fitness assessment batteries
to a satellite site in Latin America, we implemented a
comprehensive and empirically rigorous measurement strategy
for the assessment of the environmental versus organismic
determinants of healthy aging and dementia in Latin Americans.
Primary cognitive outcomes were latent residual scores derived
from a 16 subtest neuropsychological battery: Verbal Memory,
Visuospatial Processing, Simple Attention, Set Maintenance
and Shifting, and Reasoning. Physical fitness outcomes included
the 6-minute walk time, a proxy of cardiorespiratory fitness and
measures of function and disability. Results: Higher fitness
(faster walk times) was significantly correlated with better
Simple Attention and Visuospatial Processing abilities. Smoking
history significantly attenuated the relationships observed
among these variables. Conclusions: Consistent with a recent
clinical trial completed by the KU ADC, healthy Costa Rican
older adults who were more fit also had better visuospatial
processing ability and better simple attention. Future clinical trials
of exercise and exercise interventions should consider the
moderating effect of cardiovascular fitness, smoking status, and
potentially of other lifestyle variables to optimize the effects of
exercise on cognition.
