Abstract
.0 ± 10.7 ml · kg−1 · min−1). Each subject performed a minimum of two, one-mile track walks as fast as possible. The two fastest walks (T1, T2) with elapsed times within 30s were used for subsequent analyses. Heart rates were monitored continuously and recorded every one-quarter mile. Multiple regression analysis (best sub-sets) to estimate V̇O2max (l · min−1) yielded the following predictor variables: tract walk-1 time (T1); fourth quarter heart rate for track walk-1 (HR1–4); age (yr); weight (lb); and sex (1 = male, 0 = female). The best equation (N = 174) was: V̇O2max = 6.9652 + (0.0091·WT) – (0.0257·AGE) + (0.5955·SEX) – (0.2240·T1) – (0.0115·HR1–4); r = 0.93, SEE = 0.325 1 · min−1. Comparing observed and estimated V̇O2max values in a cross-validation group (N = 169) resulted in r = 0.92, SEE = 0.355 1·min−1. Generalized and sex-specific equations to estimate V̇O2max (ml·kg−1 · min−1) were also generated. The accuracy of estimation as expressed by SEE was similar among the equations. The results indicate that this one-mile walk test protocol provides a valid sub-maximum assessment for V̇O2max estimation ©1987The American College of Sports Medicine...
