Protocol - Cardiorespiratory Fitness - Non-Exercise Test Estimate
Cardiorespiratory fitness is estimated from a non-exercise test model that includes gender, age, body mass index, resting heart rate, and self-reported physical activity. Capture this information via standard methods, and add the values to Jurca and colleagues’ (2005) worksheet. Follow the equation in the worksheet to determine the maximal metabolic equivalent level.
There may be inappropriate expectations of the precision of the estimate of maximal capacity. The measure may be used to estimate the relative level of cardiorespiratory fitness of an individual within a group but may not be an accurate predictor of an individual’s capacity. Specifically, research has shown that this non-exercise test predicts a person’s cardiorespiratory fitness within 1.5-2.0 METs of the true fitness score.
Measure and record the following information about the participant.
- Age (years)
- Height (centimeters)
- Weight (kilograms)
- Body Mass Index (BMI) in kilograms per meter2 - BMI = (weight in lbs X 703)/(height in inches)2 or (weight in kilograms)/(height in meters)2
- Resting heart rate (HR) - measured HR from person’s wrist pulse after 5 minutes of rest in the supine position
Administer the questions from the five-category physical activity scale, found in Step 1 of the worksheet of Jurca et al. (2005). Add age, height, weight, and so forth to the equation in Step 2 of the worksheet to calculate the estimated MET value.

Personnel and Training Required
This protocol requires a technician who is trained to collect anthropometric measures such as height (centimeters), weight (kilograms), and resting heart rate.
Digital scale, stadiometer
|Specialized requirements for biospecimen collection||No|
|Average time of greater than 15 minutes in an unaffected individual||No|
Mode of Administration
Ages 18 or older
This method of determining maximal metabolic equivalent level is reportedly reliable in three large studies of different age groups. The measurements are frequently obtained in health care settings. After the values are added to the model, the results may be used as a measure of aerobic capacity (a predictor of chronic disease morbidity) and to estimate a person’s disease prognosis.

Cardiorespiratory Fitness - Non-Exercise Test Estimate
May 10, 2010
This measure of aerobic capacity combines anthropometric measurements with self-reported physical activity to estimate cardiorespiratory fitness.
The purpose of this measure is to assess cardiorespiratory fitness, a predictor of chronic disease and mortality.
