Abstract

Based on the energetics theory, the purpose of the present study was to examine whether changes in feeling states reflecting energetic resources mediate the facilitative effect of acute exercise on cognitive flexibility. Participants (N=58, age 50-64) were randomly assigned to moderate exercise (60 percent of heart rate reserve), moderately-intense exercise (70 percent of heart rate reserve), and a movie-watching control group after performing a maximal exercise test. Cognitive flexibility and feeling states were assessed individually immediately before and after one session. Enhancement of feeling states as well as of cognitive flexibility was found in both exercise groups; however, the enhanced feelings were disassociated from the improvement in cognitive flexibility. The difficulties in assessing hypothetical constructs such as arousal and fatigue were pointed out. Assuming that the positive immediate effects of acute exercise may serve as a catalyst for adhering to a continuous exercise routine, it was recommended to further explore the link between cognition and energy resources following acute exercise.
