This study examines the influence of so-called biorhythms on circulatory parameters (heart rate, systolic and diastolic blood pressure) at rest and during ergometric exercise. It was not possible to predict individual responses based on a postulated biorhythmic periodicity of 23 and 28 days and on the birthdate in any uniform manner. The positive effect of the positive phase and negative effect of the negative phase postulated by the biorhythmy was not found. No connexion was found between the subjective condition of the probands and any rhythm at all. At the significance level (p = 0.05) the differences of the variables (systolic and diastolic blood pressure, as well as heart rate) were found only in short phases of the examination and were not observed through out the whole experiment. The differences in the response of the parameters in male and female subjects points to the existence of sex-specific rhythms. The results of multivariance analysis show the existence of the "rhythm" factor. Hence, it is probable that every person has his own individual rhythm, or system of rhythms. It is not possible to prove and reproduce these individual rhythm by means of tables, diagrams etc.
本研究考察了所谓的生物节律对静息状态及测力运动期间循环系统参数（心率、收缩压和舒张压）的影响。基于假定的23天和28天生物节律周期以及出生日期，无法以任何统一的方式预测个体反应。未发现生物节律理论所假定的积极阶段的积极作用和消极阶段的消极作用。未发现受试者的主观状态与任何节律之间存在联系。在显著性水平（p = 0.05）下，仅在检查的短阶段发现变量（收缩压、舒张压以及心率）存在差异，且在整个实验过程中未观察到这种差异。男性和女性受试者参数反应的差异表明存在性别特异性节律。多变量分析结果显示存在“节律”因素。因此，很可能每个人都有自己独特的节律或节律系统。无法通过表格、图表等方式证明和再现这些个体节律。
