Abstract
Static and dynamic tests with work-load changes on the bicycle ergometer were performed to analyse the heart rate response in man. Hitherto, aperiodic and periodic test signals were used, having the disadvantage that they give no maximal information about the analyzed system within shortest time for experiment and evaluation. For the first time, optimal work-load sequences for the linear impulse response model were used avoiding the discussed disadvantages. These sequences are based on the theory of an active design of experiments.First results indicate the possibility of a good analysis of the dynamios of the heart rate response. Of special interest for clinical purposes is the diminished experimental time of 1/20 and the reduced time for evaluation of 1/5 as compared to tests with sine-wave work-load patterns. Statements for approximation of the system are presented from investigations of the model “workload/heart rate” and are discussed using physiological knowledges and aspects of the systems theory.
