Abstract
The daily energy expenditure of 10 housewives was studied by heart-rate telemetry. The mean heart rate was related to oxygen consumption by individual heart rate-oxygen consumption regressions from work carried out on a bicycle ergometer. Comparisons were made of this technique against direct respired air collection in three subjects and the techniques [See table in the PDF file] varied 0.1 liter O2/min. The housewives worked at 40% of their maximum aerobic work power.
