Abstract
Because of there being an aging society in Taiwan, individuals among this population will decline in cognitive function with increasing age. Therefore, how to prevent decline and maintain cognitive function has become a very important issue. In recent years, many scholars have examined the relationship between exercise and cognitive function using meta-analysis and observed that acute exercise has positive effects on cognitive function. Further investigations on the effect amounts, however, found that there are significant differences in those results, and also mentioned that the experiment designs may have been the reason for these discrepancies, meaning that the dose-response is important to exploring the results of the targeted issue. The purpose of this study is to explore the effects of dose-response exercise on cognition in late middle-aged adults. The study recruited 40 participants, aged 55-65, in good health, and in turn had them do four conditioning exercises using a counterbalance plan: control (reading) as well as 20 minutes, 30 minutes, and 55 minutes of doing acute exercise. The cognitive measurement task was a Stroop test, and acute exercise intensity was considered as a 65% heart rate reserve (HRR), using an ergometer. The findings indicated that acute exercise for 30 minutes improved information efficiency and interference inhibition, while acute moderate exercise for 20 and 55 minutes did not significantly show any difference regarding the Stroop test performance. Our results will be useful for establishing exercise descriptions for late middle-aged adults, and will provide evidence related to the dose-response relationship between exercise duration and cognitive function.
Key word: acute exercise, cognitive function, Stroop test, dose-response
