Die Relation von Arbeits- und Grundumsatz zum Gesamtumsatz bei älteren Personen mit körperlicher Belastung

Abstract

The relationships between age, body length, and body weight on the one hand, and the total metabolism and the energy metabolism on the other were obtained for 146 aged persons, including 78 women, who performed physical work. Both the total metabolism and energy metabolism decrease with increasing age. The decrease is particularly pronounced in the case of higher body weight, less with increasing body length. With reference to a "mean weight" (as published by the Society of Actuaries) it appears that nearly all male or female persons with a weight in excess of this mean weight, have a lesser energy metabolism. Comparisons of basal metabolism with both the total and the energy metabolism show likewise for both sexes that, in the case of lower basal metabolism values (according to tables), one finds in general higher total metabolism, and especially much higher energy metabolism. The lower energy metabolisms in the case of persons with a higher body weight are also caused by the fact that, compared with persons of mean weight, it requires too many calories to move ones own body. The results of these investigations point to the fact that the basal metabolism of aged persons along physical work does not decrease.
