A new method for detecting anaerobic threshold by gas exchange.
Excess CO2 is generated when lactate is increased during exercise because its [H+] is buffered primarily by HCO-3 (22 ml for each meq of lactic acid). We developed a method to detect the anaerobicExpand

Parameters of ventilatory and gas exchange dynamics during exercise.
To determine the precise nonsteady-state characteristics of ventilation (VE), O2 uptake (VO2), and CO2 output (VCO2) during moderate-intensity exercise, six subjects each underwent eight repetitionsExpand

Effect of interbreath fluctuations on characterizing exercise gas exchange kinetics.
Breathing has inherent irregularities that produce breath-to-breath fluctuations ("noise") in pulmonary gas exchange. These impair the precision of characterizing nonsteady-state gas exchangeExpand

Optimizing the exercise protocol for cardiopulmonary assessment.
Twelve normal men performed 1-min incremental exercise tests to exhaustion in approximately 10 min on both treadmill and cycle ergometer. The maximal O2 uptake (VO2 max) and anaerobic threshold (AT)Expand

Predicted values for clinical exercise testing.
Following thorough evaluation at rest, 265 of 400 current or ex-shipyard workers rode a cycle ergometer with equal work increments each minute to exhaustion while continuous multiple noninvasiveExpand

A test to determine parameters of aerobic function during exercise.
A short-duration cycle ergometer exercise test has been developed that allows four parameters of aerobic function to be discerned. These are the maximum O2 uptake, anaerobic threshold, workExpand

Abstract The measurement of the respiratory gas exchange ratio (R) during a standard exercise test is used to detect the onset of anaerobic metabolism during exercise, which results from failure ofExpand
