Objective: In this study we provided the first experimental evidence integrating behavioral neurophysiological and biochemical data to clarify the association among aerobic fitness acute aerobic exercise and executive control function Methods: Fifty-four young male adults were classified into higher- lower-aerobic fitness and control groups Each participant performed a task switching paradigm before and after a 30-min session of acute moderate exercise or resting session while the behavioral data electrophysiological indices and blood samples were collected and analyzed Results: In the switch cost analysis the results did not show any effects from acute exercise or the level of aerobic fitness on P3 latency and accurate rate However RT was faster in all groups P3 amplitude was greater for the higher- than the lower-aerobic fitness participants in the post-exercise session In the mixing cost analysis although P3 amplitude and accuracy were not affected by acute exercise or aerobic fitness RT was shorter in the exercise intervention groups P3 latency was also shortened due to the exercise intervention in the higher-aerobic fitness group not in the lower-aerobic fitness group Serum BDNF was increased in two exercise intervention groups such changes were not correlated with the changes in cognitive performance Conclusion: Acute aerobic exercise can lead to more efficient executive function especially in the higher aerobic fitness adults BDNF levels were elevated in response to acute exercise and may be a candidate that influences cognitive performance following acute exercise
