[영문]This study assessed the relationship between cardiovascular fitness and temporal preparation in elderly persons. 110 older adults (aged 60?69 or 70?79 years) were sorted into low- and high-fit groups based on aerobic fitness level estimated with a walking test. Response preparation processes were assessed with reaction time tasks in which short (1, 3, 5 s) and long (5, 7, 9 s) preparatory intervals varied randomly. The results suggest a better ability in high-fit individuals to maintain preparation over time (up to 9 s). Results of the present study suggest that in older adults, a high level of aerobic fitness is associated with more efficient response preparation processes
