Abstract

VO₂max is the gold standard to assess cardiovascular fitness, an important factor in the longevity of health. Consequently, not everyone can perform a maximal cardiovascular test. PURPOSE: To determine the accuracy of the 1-mile or 1.5-mile run to predict VO₂max. METHODS: Field runs were counterbalanced and performed on an outdoor, all-weather 400m oval track. Subjects (N=114) warmed up and stretched, then lined up single file and signaled to go in ten-second increments. At the end of the run, HR, RPE (Borg’s 6-20) and time was recorded. VO₂max: subjects were fitted with a Polar heart rate monitor, a headgear to support a one-way valve mouthpiece that was connected to a ParvoMedics TrueOne 2400 metabolic cart and performed a standard Bruce protocol on a motorized treadmill until exhaustion. Pearson’s correlation coefficient were used to assess the relationship between VO₂max and the field runs. A two-way random (constancy) intraclass correlation coefficient (Cronbach’s Alpha) was used to assess reliability between the measures. Repeated measures ANOVA was used to assess differences between actual VO₂max from the treadmill and predicted the timed runs. Simple linear regression was used to create a prediction equation for each field run. Alpha was set at .05 for all tests. RESULTS: VO₂max and VO₂max estimated from the 1-mile run (r(112) = .795, p = .001) as well as VO2max estimated from the 1.5-mile run (r(112) = .845, p = .001). Cronbach’s Alpha indicated high reliability between VO₂max and VO₂max estimated from the 1-mile run (Cronbach’s(113) = .874, p = .001) and from the 1.5-mile run (Cronbach’s(113) =. 916, p = .001). Repeated measures ANOVA show a significant difference among the three measures of VO₂max (F(2, 112) = 69.9, p = .001), with pairwise comparisons indicating a significant difference between VO₂max and VO₂max estimated from the 1-mile run (p = .001, SEE = 5.3 ml/kg/min) as well as between VO₂max and VO₂max estimated from the 1.5-mile run (p = .001, SEE = 5.3 ml/kg/min). New Prediction Equations VO₂max= 75.056-(3.879*1-mile (min)), p = .001, SEE= 4.8 ml/kg/min and =76.775-(2.543*1.5-mile (min)), p = .001, SEE = 4.6 ml/kg/min. CONCLUSION: While significant differences exist between actual and predicted VO₂max, common field equations are quite reliable. In assessing a population similar to this sample, the new equations provide greater accuracy.
