SYMPOSIUM PROCEEDINGS I956 The bottleneck in the application of indirect calorimetry is still the need for laborious and skilful gas analysis. I t is this bottleneck that is now under attack in this laboratory. If the attack is successful, the results will be, first a robust oxygen analyser for laboratory use, with a very short response time and small dead space, and later an adaptation of it s...

background : underweight as a public health problem in young women is associated with nutritional deficiencies, menstrual irregularity, eating disorders, reduced fertility, etc. since resting metabolic rate (rmr) is a necessary compo-nent in the development of nutrition support therapy, therefore we determined the accuracy of commonly used pre-dictive equations against rmr measured by indirect ...

In critical care, particular attention is paid to disorders which lead to cerebral dysfunction. Hypoxia is the most common example and considerable effort is devoted to avoiding this problem. If the brain is deprived of fuel, as in hypoglycaemia, the outcome is similar yet far less attention is paid to maintaining an adequate and appropriate long-term fuel supply. Indirect calorimetry has been ...

Meal-induced thermogenesis (MIT) research findings have been highly inconsistent, in part, due to the variety of durations and protocols used to measure MIT. In the present study, we aimed to determine the following: (1) the proportion of a 6 h MIT response completed at 3, 4 and 5 h; (2) the associations between the shorter durations and the 6 h measures; (3) whether shorter durations improved ...

In the single stance phase of walking, center of mass motion resembles that of an inverted pendulum. Theoretically, mechanical work is not necessary for producing the pendular motion, but work is needed to redirect the center of mass velocity from one pendular arc to the next during the transition between steps. A collision model predicts a rate of negative work proportional to the fourth power...

AIM The purpose of this review was to assess existing evidence on the effects of chronic dietary macronutrient composition on substrate oxidation during a fasted state in healthy and overweight subjects. METHODS A systematic review of studies was conducted across five databases. Studies were included if they were English language studies of human adults, ≥19 years, used indirect calorimetry (...
