To estimate the activity of the sympathetic nervous system excretion of noradrenaline (NA) and adrenaline (A) of members of national teams (8 different olympic disciplines) has been looked at. Measured by GC/MS the catecholamines showed some characteristics that can be expressed by the NA/A-ratio which is independent of sports-discipline, gender and age (17 to 35 years): morning-urine, representing sleeping-time, expressed good recreation with NA/A > 10 and nervousness followed by low performance with NA/A < 8. Athletes longing for good performance may be stressed by time-shift, high-altitude training or by sharing their sleeping-room with another person-but nevertheless there are most important parallels in the reaction we can see for students during examination-time, shift-workers and patients. The experience made by measuring NA/A during sleeping time of athletes allows to give some physiologically based explanation about effects of the sympathetic nervous system. So NA/A-ratio can become an easy to handle tool in the field of diagnostic and therapeutic work.
为了评估交感神经系统的活性，研究人员观察了国家队成员（8个不同奥运项目）的去甲肾上腺素（NA）和肾上腺素（A）排泄情况。通过气相色谱/质谱法测量，儿茶酚胺呈现出一些特征，这些特征可以用NA/A比值来表示，该比值与运动项目、性别和年龄（17至35岁）无关：晨尿代表睡眠时间，NA/A>10表示恢复良好，而NA/A<8则表示紧张并伴有表现不佳。渴望取得良好成绩的运动员可能会因时差、高原训练或与他人合住一间卧室而感到压力——不过，我们在学生考试期间、轮班工作者和患者身上看到的反应有最重要的相似之处。在运动员睡眠时间测量NA/A的经验，有助于对交感神经系统的作用给出一些基于生理学的解释。因此，NA/A比值可以成为诊断和治疗工作领域中一种易于操作的工具。
