Measurement of the psychological stress with the sports activity

选择评价影响比赛成绩和比赛状态的心理应激的生化指标。值得注意的指标是两种唾液成分(嗜铬粒素A和皮质醇)。对大学生运动员在瞬时应激状态(测量I)和长期运动应激状态(测量II)下的唾液成分进行了定量测定。在此基础上，考察了体育活动中的心理应激对心理状态和运动成绩的影响。在测量一中，通过唾液成分、心率反应、心理测试(STAI)来测量运动员在给予两个瞬时应激问题(受控应激刺激和赛前应激状态)时的应激反应。结果也是，唾液成分高价值嗜铬粒蛋白-A对心算问题做出了敏感的反应。很多运动员在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(二维感受量表)对高原训练同住3周的应激反应进行测量。结果表明，许多高原训练无效的运动员在下榻后半段时间内舒适度降低，唾液成分偏弱、偏高，提示其具有通过应激反应系统(HPA轴和S/A系统)两种唾液成分将心理应激评价为对成绩和状态的滥用的功能。然而，在预测绩效下降的评估标准制定方面，还没有到这一步。

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.
