Title: Simultaneous Comparison of Respirometer and Heart-Rate Telemetry Techniques as Measures of Human Energy Expenditure
Abstract: Heart rate was found to be a good predictor of energy expenditure in each of six activity levels in 24 young adult males. The coefficient of regression (r) of heart rate on energy expenditure was greater than 0.95 while the standard error of estimate was less than 0.64 kcal/min in 21 of 24 subjects. A simultaneous comparison of heart rate-diary, accumulated pulse, and respirometer-diary was made while 15 subjects carried out a sequence of steady-state activities for 4 hr. Considered as a group there was less than 10% variation among the three techniques. For the measurement of energy expenditure in individuals under usual home or work environment the accumulated-pulse technique has the advantage of interfering least with a subject’s usual behavior.
