Abstract
The purpose of this study was to investigate the effects of voluntary “momentary” control of respiration on reaction time and state-anxiety which was measured by STAI-1 test. Subjects were asked to react to the stimulus on CRT by pressing the botton with or without voluntary “momentary” control of respiration. The results showed that mean reaction time was shorter and the score of STAI-1 was higher in the controlled respiration condition than in the spontaneous respiration condition. These results showed that voluntary “momentary” control of respiration heightened subjects' concentration and improved their performance. These results also suggest that voluntary “momentary” control of respiration method may improve motor performance.
