Background: Exercise is known to providephysical and psychological health benefits in adults.
There have been many studies on the effects of exercise on cognitive function in older people
but few have dealt with the effects of exercise on cognitive function in adults aged 50 yr and older.
Methods: The subjects of this study were 380 men and women aged ≥50 yr who received health
examination at a university hospital in Seoul during the period between December, 2004 and April,
2005. Exercise behavior was surveyed with questionnaires forthe frequency of aerobic exercises
30 min or longer per week for the latest 3 months. Those who exercised once a week or less
were identified as the no-exercise group, those 2-3 times per week were grouped into the occasional
exercise group, those 4-5 times per week were grouped into the moderate exercise group,
and those 6 times or more per week were grouped into the frequent exercise group. Cognitive
function was measured using Korean Mini-mental Status Examination (K-MMSE). Results: Of
the male subjects, 44 (23.9%) fell into the no-exercise group, 44 (23.9%) into the occasional
exercise group, 67 (36.4%) into the moderate exercise group, and 29 (15.8%) into the frequent
exercise group. In the female population, the numbers were 91 (46.4%), 38 (19.4%), 43 (21.9%)
and 24 (12.2%), respectively. The mean K-MMSE scores were 26.9±2.2 in the no-exercise
group, 27.7±2.0 in the occasional exercise group, 28.1±1.7 in the moderate exercise group,
and 28.9±0.9 in the frequent exercise group, thus showing that the scores increased with increases
in exercise status (p<0.001). Using multiple regression analysis controlling for age, gender,
academic qualification, smoking, drinking, cholesterol levels and prior disease histories such
as hypertension and diabetes, we found that the K-MMSE scores in the moderate exercise group
and the frequent exercise group were higher by 0.7 and 1.5, respectively, compared to that in
the non-exercise group (p=0.002 and p<0.001, respectively). Conclusions: These findings
suggest that frequent exercise is associated with higher cognitive functions in adults aged 50
yr and older. In future studies, we need to assesswhether this is the direct effect of exercise or
an indirect effect from improving cardiovascular disease risk factors.
