Prediction of Cardiac Response to Physical Stress

This paper presents a method for predicting an individual's cardiac response to a series of fixed intensity tasks. It was determined that cardiac responses to exercise at given work loads are similar for subjects of the same sex and level of physical fitness when they are expressed in terms of resting heart rate. Using this observation as a basis, a prediction model was developed by extrapolating from emperically derived heart rate patterns. The prediction error was no more than five to ten percent of the actual heart rate value in ninety percent of the predictions.
