Energetic cost of carrying loads: have African women discovered an economic way?
(Nature Publishing Group, 1986-02)
When travelling in East Africa one is often surprised at the prodigious loads carried by the women of the area. It is not uncommon to see women of the Luo tribe carrying loads equivalent to 70% of their body mass balanced ...
Design of the mammalian respiratory system. IX. Functional and structural limits for oxygen flow.
(1981-04)
This paper presents the synthesis and interpretation of a series of correlated studies of the mammalian respiratory system--measurements of maximal rate of O2 consumption, the lung's diffusing capacity, the mitochondrial ...
Design of the mammalian respiratory system. III Scaling maximum aerobic capacity to body mass: wild and domestic mammals.
(1981-04)
The purpose of this study was to determine whether the maximal rate of oxygen consumption (Vo2max) is scaled proportionally to Mb1.0, as the diffusing capacity of the lung, or proportionally to Mb0.75, as the standardized ...
Moving cheaply: energetics of walking in the african elephant
(1995)
Large animals have a much better fuel economy than
small ones, both when they rest and when they run. At rest,
each gram of tissue of the largest land animal, the African
elephant, consumes metabolic energy at 1/20 the ...
Design of the mammalian respiratory system. II. Measuring maximum aerobic capacity.
(1981-04)
We describe a simple and reproducible procedure for measuring maximal O2 consumption (Vo2max) that can be used for mammals spanning a wide range of body mass (Mb). Vo2 of trained animals was measured as a function of speed ...
Design of the mammalian respiratory system. V. Scaling morphometric pulmonary diffusing capacity to body mass: wild and domestic mammals.
(1981-04)
This paper utilizes a comparative approach to establish the relationship between morphometric diffusing capacity for oxygen (DLo2) and maximal oxygen consumption (Vo2max). DLo2 and Vo2max were determined on the same 21 ...
Energetics and mechanics of terrestrial locomotion. I. Metabolic energy consumption as a function of speed and body size in birds and mammals.
(1982-04)
This series of four papers investigates the link between the energetics and the mechanics of terrestrial locomotion. Two experimental variables are used throughout the study: speed and body size. Mass-specific metabolic ...
A comparison of gastrointestinal water content and osmolality in East African herbivores during hydration and dehydration
(University of Nairobi, 1978-07)
A wealth of information is available concerning the ‘normal’ gastrointestinal mechanisms within various species of herbivores (Alexander, 1962; Church, 1971; Quarterman, Phillips & Lampkin, 1957). In addition, the effect ...
