For the first time, the reaction of the cardiovascular system during day and night in young people was examined. We were mostly interested in the influence of the nervous system and any autonomic mechanism. We examined 20 subjects at 4-hour intervals on the ergometer (active exercise) and on the tilt-table (passive exercise) to find out the rhythm in the circulatory regulation. The test person was kept in vertical position on the tilt-table for 10 minutes. On the ergometer he had to perform a work-load of 100 Watt for 10 minutes. We measured pulse rate and blood pressure; we introduced new terms for the evaluation. "Orthostatic Index" and "Performance Index" will be further explained. The results were: A minimum in the orthostatic stability around 1 p.m. and 1--5 am, and a performance maximum at 1 p.m. and 5 p.m. Further details will be reported.
首次对年轻人昼夜期间的心血管系统反应进行了检查。我们主要关注神经系统和任何自主机制的影响。我们每隔4小时对20名受试者在测力计（主动运动）和倾斜台上（被动运动）进行检查，以找出循环调节中的节律。测试者在倾斜台上保持垂直姿势10分钟。在测力计上，他必须以100瓦的工作量持续10分钟。我们测量了脉搏率和血压；我们引入了新的评估术语。“直立指数”和“运动表现指数”将进一步解释。结果是：下午1点左右和凌晨1点至5点直立稳定性最低，下午1点和5点运动表现最佳。将报告更多详细信息。
