Fluid intelligence in an older COPD sample after short- or long-term exercise

It is concluded that improvements in aerobic fitness are associated with gains in fluid intelligence after 3 and 18 months of exercise training in COPD patients. However, at 18 months, exercise group was not predictive of the gains in cognitive performance. Therefore, a 3-month exercise program may be a sufficient impetus to foster these cognitive gains in COPD patients.
