Development of Field Tests of Aerobic Fitness
“Field-based” tests are developed by having a large group of participants complete a given test along with a “lab-based” test. With some statisticalprocedures, a “line of best fit” is created to represent the overall trends among the participants. Once the equation is developed, individuals can get estimates of their fitness level just by completing the field test. The accuracy of the estimates depends on the representative nature of the sample and the sample size. (Separate equations would typically be developed for different genders and would include age and other predictors such as weight in the equation)
This slide provides a brief description of the derivation of most field based assessments of aerobic fitness. Field tests are necessary because it is not easy or practical to have everyone complete lab based fitness assessments.
By using the procedures described here, scientists have developed equations that predict fitness levels based on the results of the field test. These tests work quite well for most applications.
Because the fitness determinations are only estimates and because individuals may perform differently on different tests, results may vary across tests.
