Prediction of maximum oxygen consumption from walking, jogging, or running

Area of Science:

• Exercise Physiology
• Sports Science
• Cardiorespiratory Fitness Assessment

Background:

• Accurate assessment of maximal oxygen uptake (VO2 max) is crucial for evaluating cardiorespiratory fitness.
• Existing maximal tests can be time-consuming and require specialized equipment.
• Submaximal tests offer a practical alternative for large-scale fitness evaluations.

Purpose of the Study:

• To develop and validate a submaximal, 1.5-mile endurance test for estimating VO2 max in college-aged students.
• To provide a reliable and accessible field test for assessing cardiorespiratory fitness.
• To compare the accuracy and reliability of the developed test with existing methods.

Main Methods:

• 101 college students (ages 18-26) completed a 1.5-mile walking, jogging, or running test twice at a "somewhat hard" intensity (RPE=13).
• Participants also underwent a maximal graded exercise test for comparison.
• Multiple linear regression analysis was used to develop prediction equations for VO2 max.

Main Results:

• A prediction equation using gender, body mass, and elapsed time demonstrated acceptable validity (R=.86) and reliability (ICC=.93).
• A secondary equation incorporating heart rate showed higher validity (R=.90).
• The test is comparable in accuracy and reliability to other field tests for VO2 max estimation.

Conclusions:

• The developed submaximal 1.5-mile test provides a valid and reliable method for estimating VO2 max in college students.
• The test is practical for mass testing, requiring minimal equipment (stopwatch, measured distance).
• It accommodates a wide range of fitness levels, making it versatile for diverse populations.
