Modeling Percentile Rank of Cardiorespiratory Fitness Across the Lifespan.

ABSTRACT:

Purpose

The purpose of this investigation was to create an equation for continuous percentile rank of maximal oxygen consumption (VO₂ max) from ages 20 to 99.

Methods

We used a two-staged modeling approach with existing normative data from the American College of Sports Medicine for VO₂ max. First, we estimated intercept and slope parameters for each decade of life as a logistic function. We then modeled change in intercept and slope as functions of age (stage two) using weighted least squares regression. The resulting equations were used to predict fitness percentile rank based on age, sex, and VO₂ max, and included estimates for individuals beyond 79 years old.

Results

We created a continuous, sex specific model of VO₂ max
