Equations of Voutilainen et al for Estimating Maximal Oxygen Uptake from the Ratio of Heart Rates at Maximum Exertion and at Rest in a Middle-Aged Male
Voutilainen et al reported equations for estimating maximal oxygen uptake from ratios of heart rate taken after maximal exercise and at rest. The authors are from the University of Eastern Finland.
Patient selection: around 50 years old without cardiovascular disease, asthma or cancer
Parameters:
(1) heart rate at rest in beats per minute
(2) heart rate at maximal exercise
heart rate ratio =
= (heart rate at maximal exercise) / (heart rate at rest)
estimated VO2max in mL per min per kg =
= (8.43 * (ratio)) + 10.46
estimated VO2max in mL per min per kg =
= 12.11 * (ratio)
To improve accuracy the score can be adjusted for BMI, smoking status and daily physical activity.
