| Abstract | Introduction: Extensive evidence documents arousal modulation of declarative memory in humans. However, little is known about the arousal modulation of implicit motor memory. The purpose of this study was to examine the effects of a post-acquisition acute exercise stress on implicit motor memory consolidation. Materials and Methods: Forty healthy subjects were randomly divided into stress (10 men and 10 woman) and non- stress (10 men and 10 woman) groups. Experiment consisted of two phases of acquisition and retention. Serial Color matching (SCM) task was used for this study. In acquisition period, all groups practiced the task for six blocks of 150 trials. Following, the stress group performed exercise on a treadmill until the moment of exhaustion while the non stress group did rest. In retention, all groups practiced the SCM task in one block. During the experiment the trends of saliva cortisol changes were measured. Results: Acute exercise stress leads to a significant increase in salivary cortisol level. While the non-stress group did not show enhancement of SCRT learning across the 24 hours delay interval, the stress group showed substantial enhancement across the same time (P | en |
