This study aims at examining the relationship between psychobiological stress response following mental stress testing and exercise habits in the field-experimental paradigm terms.
We investigated exercise habits on 327 volunteers by divided into the exercise habits (more than 3 days/week and more than 30 minutes/day) and the no exercise habits groups. The participants rested on an armchair for 10 min and, then, were exposed for the laboratory stress inductions (the speech task and the arithmetic task) for 10 min. Finally, they took a recovery period for 30 minutes.
The result showed that heart rate of the exercise habits group was lower than that of the control group during the stress inductions and the recovery period. In addition, cortisol of the exercise habits group was lower than that of the control counterpart during the stress induction.
These results indicate that exercise habits attenuate psychobiological stress response in the acute stress situation.
