Verification of Maximal Oxygen Uptake in Obese and Nonobese Children.

Verification of Maximal Oxygen Uptake in Obese and Nonobese Children.:

Purpose: The purpose of this study was to examine whether a supramaximal constant load verification test at 105% of the highest work rate would yield a higher V[Combining Dot Above]O2max when compared with an incremental test in 10 - 12 year old nonobese and obese children.

Methods: Nine non-obese (BMI percentile: 57.5 +/- 23.2) and nine obese (BMI percentile: 97.9 +/- 1.4) children completed a two-test protocol that included an incremental test followed 15 minutes later by a supramaximal constant-load verification test.

Results: The V[Combining Dot Above]O2max achieved in verification testing (Nonobese: 1.71 +/- 0.31 and Obese: 1.94 +/- 0.47 L/min) was significantly higher than that achieved during the incremental test (Nonobese: 1.57 +/- 0.27 and Obese: 1.84 +/- 0.48 L/min; P
