Body composition, physical activity status, cardiovascular risk factors, 6-minute walk test (6MWT), and Mini-Mental State Examination (MMSE) were measured. The linear regression model was used to examine the association between baseline MMSE and mobility improvement. Mean distance of 6MWT was 462.8±71.6 meter at baseline and mean change after the exercise intervention was 33.7±34.9 meter. The mean MMSE score at baseline was 27.6±1.9. After adjusting for baseline covariates, we found that baseline MMSE score was significantly associated with improvement in mobility among older adults after the exercise intervention. Cognitive function strongly influences the effect of exercise intervention on mobility among older adults.
