Influence of load magnitude and duration on the relationship between human arterial blood pressure and flow rate

Mariunas M., Kuzborska Z.

Acta of Bioengineering and Biomechanics

2011

Vol. 13, no. 2

67-72

This article analyses the dependence of load value, age, gender and pathology on arterial blood pressure and blood flow rate. Three male and female different age groups were examined. The load applied ranged from 50 W to 150 W. The hodograms for different genders and age groups were made. These hodograms show the human adaptability to chosen maximal values of arterial blood pressure and blood flow rate and the influence of warming-up on the process of adaptation. It was found out that the maximum blood flow rate delayed the maximum arterial blood pressure during a certain period of time. The criterion for evaluating human efficiency was established. It was revealed that the hodograms for humans with certain pathology differ in curve shapes and their interlocations from those for healthy humans. It was shown that the results obtained could be used to determine a human adaptability to the load applied and human efficiency level.
