The biochemical marker which evaluated the psychological stress which influences performance and condition of the sports game was selected. Noticed indexes were two saliva components (chromogranin-A and cortisol). Saliva component of the university athletes in transient stress condition (measurement I) with the sports activity and long-term stress condition (measurement II) was determined quantitatively. Then, the effect of the psychological stress with the sports activity on aspect and performance was examined. And, whether the saliva component was appropriate as a psychological stress indicator for the athletes was verified.In measurement I, the stress reaction in giving two transient stresses problems (controlled stressful stimuli and stress condition before a match of the sports game) was measured by saliva component, heart rate response, psychological test (STAI). As the result, also either saliva component high value chromogranin-A sensitively reacted to the mental calculation problem. In the many athletes, the level of cortisol was high in the psychological stress condition before a match.In measurement II, the stress reaction under high-altitude training lodging together for 3 weeks was measured by saliva component, psychological test (the two-dimensional feeling scale). As the result, lowering of the comfort feelings with the feebleness and high value of the saliva component were observed the many athletes who were not effective of high-altitude training in the latter half of lodging together.It was indicated that it had the function which evaluates the psychological stress as an abuse of performance and condition by two saliva components dividing into the stress reaction system (HPA axis and S/A system). However, it has not yet come to it in evaluation criterion preparation which predicts the lowering of the performance.

筛选出影响运动比赛成绩和状态的心理应激生化指标。注意的指标是两个唾液成分（嗜铬粒蛋白-A和皮质醇）。对大学生运动员在短暂应激状态（测量I）、运动活动和长期应激状态（测量II）下唾液成分进行了定量测定。在此基础上，研究了运动员心理应激对身体形态和运动成绩的影响。在测量I中，通过唾液成分、心率反应、心理测试（STAI），测量了在给予两种瞬时应激问题（受控应激刺激和运动比赛前的应激状态）时的应激反应。结果表明，唾液中的高值嗜铬粒蛋白-A对心算问题也有敏感反应。多数运动员赛前心理应激状态下皮质醇水平较高。测量二采用唾液成分、心理测试（二维感觉量表）测量了高原集训寄宿3周的应激反应。结果发现，在集体住宿的后半段，许多高原训练效果不佳的运动员，其舒适感降低，唾液成分的微弱和高值，表明唾液分为应激反应系统（HPA轴和S/A系统）的两个成分，具有将心理应激评定为成绩和状态的滥用的功能。然而，它还没有达到它在评估标准的准备，预测性能的降低。
