Excerpt
The purpose of the study was to determine the validity of estimating VO2max in college students from a steady-state one-half mile walk test. In this investigation, 61 male and 33 female students (n = 94), ages 18–30 (22.47 + 2.69), volunteered as subjects. VO2max of subjects was measured using the Bruce treadmill protocol followed by a one-half mile steady-state walk test on nonconsecutive days in which walk time (min) and end exercise heart rate (HR) upon completion of the test were determined. Using regression analysis, the following generalized equation was developed: VO2max (ml. kg-1. min-1) = 143.02 −.0981 × weight (Ibs) + 7.742 × gender −6.318 × walk time (min) - .326 × end HR (bpm). In addition, gender specific equations were developed for males: VO2max (ml. kg-1 · min-1) =161.410 −.099 × weight (lbs) −6.296 × walk time (min) −.413 × end HR (bpm) and females: VO2max (ml · kg-1 · min-1) = 124.273 −.056 × weight (lbs) −5.502 × walk time (min) - .275 × end HR (bpm). The results (validity and error coefficients) are presented in Table 1. It was concluded that the one-half mile steady-state walk test provides a reasonably valid estimate of VO2max in non-laboratory settings. However, the generalized equation developed in this study appears to provide the greates accuracy.
