Validity of a submaximal 1-mile track jog test in predicting VO2max in fit teenagers

The purpose of this study was to validate the ability of the 1-mile jog test to predict VO(2)max in fit teenagers. Forty-one males and 42 females performed the steady-state, submaximal jogging test on an indoor track, along with a maximal graded exercise test (GXT) on a treadmill. Open circuit calorimetry was used during the GXT to measure maximal oxygen consumption (VO(2)max). We generated the following age-specific prediction equation applicable to boys and girls 13-17 years old (n = 83, R-adj = .88, SEE = 3.26 ml . kg(-1) . min(-1)): VO(2)max = 92.91 + 6.50 x gender (0 = female, I = male) - 0.141 x body mass (kg)- 1.562 x jog time (min) - 0.125 x heart rate (bpm). Cross-validation results were acceptable (SEEpress = 3.44 ml . kg(-1 .) min(-1)). As a field test, the submaximal I-mile jogging rest may alleviate probicms associated with pacing, motivation, discouragement, injury, and fatigue that are sometimes associated with maximal effort timed or distance run tests.
