Comparison between the aerobic power estimated for two field tests

Abstract

The aim this study was to compare the aerobic power estimate produced from the execution of two field tests. To do so, 226 men (23.0 ± 3.0 years) were submitted to the 20-meter shuttle run (20 m-SR) and 12 minutes walking/running (12 min) tests. Although a good correlation has been verified between the tests (r = 0.79-0.81; P < 0.01), as well as a good agreement among the found individual values (Bland-Altman plots), the estimate of the VO₂max generated by 20 m-SR went higher the to have found in the 12 min test (P > 0.01), so much in relative values (46.2 vs. 45.5 ml.kg^-1.min^-1, respectively) as in absolute values (3.36 vs. 3.30 l.min^-1, respectively). The results suggest that the 20 m-SR and 12 min tests, when compared, can to produce different estimate of the aerobic power in adult men.
