Implication

Nomogram underestimation risks misclassifying fitness in young men; leaves open need for validated alternatives across training statuses.

Structured PICO

How accurate is the prediction of maximal oxygen intake from submaximal pulse rate and Vo2 in normal young men?

P
Population
Four groups of normal men, 18-24 years of age, including a sedentary group and a group of ten endurance athletes.
I
Intervention
Prediction of maximal oxygen intake (max Vo2) from submaximal pulse rate and Vo2 using the Åstrand and Ryhming nomogram and regression equations, physical training for 2.5-3 months, and removal of 14% of circulating hemoglobin.
C
Comparator
Actual measured maximal oxygen intake (max Vo2).
O
Outcome
Accuracy of prediction of maximal oxygen intake (max Vo2).surrogate

Prediction of maximal oxygen intake from submaximal pulse rate and Vo2 significantly underestimates actual max Vo2, with accuracy varying based on physical conditioning and nonspecific stresses.
