Mottola et al developed an equation to predict the maximum oxygen consumption of a pregnant woman during exercise. The authors are from the University of Western Ontario in London, Ontario.
Testing protocol: progressive treadmill test of women from 16 to 22 weeks, using a modified Balke protocol to volitional fatigue
(1) body weight in kilograms
(2) height in meters
(3) peak heart rate in beats per minute
(4) percent incline at peak (grade of slope, as a whole number from 0 to 100)
(5) speed in miles per hour (mph)
(6) body mass index (BMI) in kg per square meter
predicted peak oxygen consumption in mL oxygen per kilogram per minute =
= (0.055 * (peak heart rate in beats per minute)) + (0.381 * (percent incline)) + (5.541 * (speed in mph)) - (0.090 * (BMI)) - 6.846
• The peak oxygen consumption correlates with the woman's fitness level.
