Purpose of this study was to establish the effective method for measuring athlete's psychological stress responses with sports activities. Selected indexes were wave hights and cycles of digital plethysmography (DPG). This measurement was easy, so it doesn't impose an unnecessary burden on athelete's physical activities and mental trainings. And we can estimate sympathetic and parasympathetic functions separately if we get coefficient of variation of wave height (CV_<WH>) and coefficient of variation of pulse interval (CV_<P-P>). Two basic experiments were performed to analyze the efficiency of DPG. 1. DPG and ECG of 7 athletes who were practicing autogenic training (AT) were measured, and psychological test (SAI) was performed. 2. Two stress tasks (mental arithmetic and shocking picture) were given to 6 athletes. Then their DGP and blood stress hormones were measured, and psychological tests (SAI and SSRS-res) were performed. Next results were obtained by these analysis. 1. There was high correlation between R-R interbal of ECG and pulse-pulse interbal of DPG. And we could confirm that CV_<P-P> was appropriate to estimate parasympathetic functions. 2. Both CV_<WH> and CV_<P-P> increased when stress tasks were given. But, changes of CV_<WH> and CV_<P-P> showed different tendency between stress tasks, and among individuals. There was relation between change of emotions and blood stress hormones. And there was relation these changes and CV_<WH>. There was the tendency that CV_<WH> increased in AT. Atheletes whose rate of increase was high showed high anxiety. These results allowed us to judge that digital plethysmography was hopeful as an index for measuring psychological stress responses with sports activities.
