A Nomogram for Calculation of Oxygen Consumption from Minute Ventilation at Varying Workloads

Oxygen consumption can be difficult and time consuming to measure. At the present time there does not exist an accurate method of estimating oxygen consumption during exercise at varying workloads. This study examined the relationship between minute ventilation and oxygen consumption and from the results generated a nomogram which can be used to accurately estimate oxygen consumption from minute ventilation in normal athletic male subjects. It was also determined that although a positive smoking history did not effect the accuracy of this estimate such a history adversely effects the ability to predict maximal oxygen consumption from heart rate at sub-maximal work rates.
