Introduction Nearly all metabolic measurement systems are based on analysis of respiratory gas exchange at the mouth, thus, the calibration of these systems should consist in controlled simulation of the process of breathing. This simulation should incorporate essential physiological characteristics such as the respiration-like pattern of gas flows and the dynamic temporal profiles of O2 and CO2 concentrations, reflecting the …
What is the Gold Standard of Incompetence? Background The reason for this paper is misinformation being fed to unsuspecting prospective buyers of metabolic measurement system. These systems are known generically as Metabolic Carts (MC), CPX systems, Ergospirometry systems in Europe and also as calorimetry measurement systems; for simplicity, we will hereafter refer to them as MC’s. It appears that some …
Cycle ergometers are referred to as “ergometers”, “stationary bicycles”, or simply “bikes”. Your budget and the intended application determine the selection of an ergometer. Obviously, for home use you will expect to spend substantially less than for professional use, but even here it makes a difference whether the user is a fitness buff or a cardiac patient.Things to consider are: …
When most lay people hear the word STRESS TEST, they visualize a person running on a treadmill or pedaling on a stationary bicycle while all kinds of wires are attached. What they think of is the Cardiac Stress Test. It is not immediately obvious to everyone, that a deficiency in the performance of the heart may be caused by an …
If you are teaching physiology, metabolism and/or the use of Metabolic Measurement Systems, perhaps one of the most important subjects you should teach is to understand what factors affect the accuracy of VO2, VCO2 and Flow (volume) measurements and how to find and correct such problems. All too often we hear that a metabolic measurement system is validated by comparing …
By: Andrew Huszczuk and John Hoppe There is no advantage to true BBB measurements, and in fact there are distinct disadvantages! Early publications about measurement of VO2 and VCO2 date back to the early 1900’s, with collection of exhaled gases in bags. Then in the 1930’s Douglas used gas collection bags during his expedition to the Andes; the resulting publicity …
All references to thresholds here are in relation to VO2 testing. A search of the literature, or Google, will find references to other methods of determining some thresholds. But beware, there is much mis-information on the web! For the Aerobic Threshold I found this explanation in Wikipedia(1): “The aerobic threshold (AeT) is a term sometimes used by sports coaches and …
You take a 15-minute walk during your lunch hour, are you fit? Your neighbor plays golf twice a week, is he fit? Your mother tends her garden every day, is she fit? Your cousin runs a marathon several times a year, is she fit? (Oh yah) Who is fit? Who is not?VO2 measurements are useful in a number of applications. …
What is VO2? VO2 means oxygen consumption and usually refers tothe volume of oxygen consumed in 1 minute. The following is written in the context of VO2 measurements for fitness or athletic evaluation. Clinical VO2 testing most often involves the monitoring of EKG and other physiologic indices, and the reason for the test most likely will be to assist in …

Breathing Reserve (BR) is usually determined during a pulmonary exercise stress test. It is the difference between the maximal voluntary ventilation (MVV) and the maximum ventilation measured during the exercise test. Normal males have a breathing reserve of 15 liters per minute or 20 to 40% of the MVV. (Wasserman et al) Some experts do not believe direct MVV measurement …
