Glossary of Terms
Accuracy - Accuracy is the sum of the absolute value of the bias plus the
precision. Reported accuracy is given as percent of reading, unless
otherwise specified.
AeT - Aerobic Threshold. The oxygen consumption level where complete
aerobic metabolism is no longer sufficient, and anaerobic energy pathways
begin to assist with energy production.
AT - Anaerobic Threshold (ventilatory threshold) - During exercise, the
oxygen consumption above which aerobic energy production is
supplemented by anaerobic mechanisms, causing a sustained increase in
lactate and metabolic acidosis. Lactic acid (which is a byproduct of energy
being made from glucose) starts to build up quickly in the blood.
bias - Bias is the measurement of central tendency based on the mean.
common-mode pressure - The pressure applied to
both
ports of the
differential pressure transducer.
ergometer - An apparatus which measures work or energy expended
during a period of physical exercise.
FSO – Full scale output.
hyperventilation - Exhaling more than is being inhaled during accelerated
breathing.
level - A subset of settings within a particular protocol designed for testing
clients with different levels of fitness. These levels will appear as options
when the protocol is chosen for testing.
LPM – Liters per minute.
metabolism - The chemical processes that occur within living organisms in
order to maintain life.
METS - Metabolic equivalents. Used in exercise testing, exercise
prescription, and evaluation of functional capacity. One metabolic
equivalent (MET) is defined as the amount of oxygen consumed while
sitting at rest and is equal to 3.5 ml O2 per kg body weight x min. The MET
concept represents a simple, practical, and easily understood procedure for
expressing the energy cost of physical activities as a multiple of the resting
metabolic rate. The energy cost of an activity can be determined by dividing
the relative oxygen cost of the activity (ml O2/kg/min) x by 3.5.
