| Research Abstract |
The purpose of this study was to examine the attention mechanism and to consider the biofeedback strategies of trainability for athletes to achieve the high performance. At the first experiment, the relationship between breathing function and involuntary variability of attention for various sports players, called open skill system, was investigated to clarify the attention mechanism for competitive performance and to explore the possibility of biofeedback technical applicability. Cooperative tasks were used in this experiment to assume the situation of athletic performance in team sports. The psychophysiological evidences of the condition of getting along just fine which was important components of attention ability were obtained. TijiQuan breathing method and reverse abdominal breathing method were the best ways of decreasing state anxiety and keeping attention level as well as arousal level. These findings showed that breathing, EEG, and heart rate as an index of sport anxiety should be integrated into biofeedback system.
At the second experiment, event-related potentials, CNV and PINV, were measured to demonstrate the attention variability under competitive stress conditions. The results showed that CNV was a good index of stress anxiety, while PINV was a good index of sustainability of attention. Furthermore, those indexes reflected the two functions of attention, selective and sustained. Practical approach to explain the role of attention for behavior control was conducted at exercise yard. Subjects who did exercise with touch easily maintained their attention level during the more prolonged time. Functional movements with touch seem appropriate for attention level and /or arousal level.
