Does psychological stress improve physical performance?
The purpose of this study is to determine whether psychological stress enhances physical performance and how personality traits affect it. The annual physical test was chosen as the psychological stressor. Ninety three students ran 50 meters as part of the test and one week after that as a control. The pulse rate and time were measured and pulse rate was used as an indicator of psychological stress. All students took the anxiety-trait scale test of the State-Trait Anxiety Inventory. The pulse rate was higher and the time record was better in the annual physical test compared with that of control. When we categorized the subjects by the anxiety-trait scale test, only the high anxiety-trait students could run faster when faced with higher stress. In conclusion, psychological stress can enhance the physical performance of certain students. It is possible that psychological stress and personality traits interact and both of them affect physical performance.
