Human systolic blood pressure and heart rate were measured continuously. This was accomplished by an indirect noninvasive method employed while the subject was involved in exercise. The characteristics of the measurements, and the factors which produced those characteristics were investigated. Then, an index L composed of all of the significant factors was sat up in order to compute L-Scores. L-Score was later statistically considered as a significant indicator of evaluation of a subject's training level.
On the other hand, BP-HR Scores of each subject were obtained from BP-HR Scoring Chart. The Scoring Chart was drawn in order to serve as a scoring table for estimating subjects' training levels according to a formula which represented the characteristics of increments above resting blood pressure and heart rate. Highly significant correlation between L-Scores and BP-HR Scores, 0.94 at P<0.01, was observed.
The study concluded that synthetic investigations of multi factors such as computing L-Scores were more efficient than a singular investigation of individual factors in order to examine a human cardiovascular function from measurements of blood pressure and heart rate during exercise. For simplification of the measurements and computations, application of BP-HR Scores was considered as an effective method.
