Abstract
The relationship between average pulse rate and energy expenditure is examined, using published data that illustrate the effect on the relationship of age, sex, state of training, and physical posture. It is concluded that energy expenditure over a 24-hr period may be predicted either by using average values for the constants of relationship between pulse rate and energy expenditure, or by using a single calibration measurement. In the first case, the standard deviation of the prediction method is approximately three times, and in the second case approximately one and one-half times that of conventional respirometry methods. These methods can be used to calculate the energy expenditure of elderly and other infirm subjects, for whom it may be difficult or impossible to obtain calibration points by respirometry over a wide range of data.Keywords
