The paper “Oxygen Consumption During Fire Suppression: Error of Heart Rate Estimation” (Ergo- nomics [1991]: 1469–1474) reported on a study in which x 5 oxygen consumption (in milliliters per kilogram per minute) during a treadmill test was determined for a sample of 10 firefighters. Then y 5 oxygen consumption at a comparable heart rate was measured for each of the 10 individuals while they performed a fire-suppression
