Summary Four subjects with severe cerebral palsy were studied with heart rate telemetry and intermittent sampling of expired air gas analysis, while they permed their habitual activities. each subject, a significant relation between oxygen uptake and heart rate was found. On the basis of the heart rate recordings and the time spent on various daily activities, a mean heart rate was found each subject. The corresponding mean daily oxygen uptake was read from this line. The four individual lines of the correlation between oxygen uptake and heart rate differed significantly from each other with respect to the slope. Three of 4 lines crossed over at a heart rate of about 75 beats per minute and oxygen uptake of 11.5 ml per minute and kg body cell mass. This was regarded as a “basal” point, representing the basal cellular need in a thermoneutral environment. This “basal” point was used för calculation of energy expenditure in a less extensive study of 6 subjects. In these children, only one or two air analyses at a known heart rate were perförmed. This determination, or the average of two determinations, was connected with the “basal” point. The individual line was then used to determine the mean daily oxygen uptake. The mean daily energy expenditure found the ten subjects agreed well with the energy intake from dietary recordings, on the one hand, and body fat amounts, on the other.
