A Comparison of predictive methods for estimating aerobic fitness

&nbsp;&nbsp;The purpose of this investigation was to compare the acceptability of three exercise tests for estimating maximal oxygen uptake(VO₂max). Sixteen healthy female subjects(M±S.D.=35.38±4.27) performed the maximal treadmill test, submaximal Cycle test(Siconolfi et al. 1982), submaximal Step test(Sharkey, 1977), and submaximal one-mile walk test(Cline et al., 1987).<BR>&nbsp;&nbsp;VO₂max determined by maximal treadmill test was 38.92±4.06ml/㎏/min. Predicted VO₂max was also estimated from cycle test(31.84±3.84), step test(39.56±3.69), and one-mile walk test(39.57±3.20). Predicted VO₂max were obtained for each subject from heart rate(HR) at submaximal work loads. During the submaximal tests, heart rates were recorded from polar system(Finland).<BR>&nbsp;&nbsp;Paired sample t-test revealed significant mean difference between criterion treadmill VO₂max and cycle test. The one-mile walk test and step test VO₂max values were not significantly different from the criterion treadmill VO₂max. The correlations between criterion VO₂max and VO₂max estimated from cycle test, step test, and one-mile walk test were r=0.65, r=0.64, and r=0.83, respectively. These results suggest that step test and one-mile walk test are satisfactory predictive method for VO₂max estimation in 30 to 39-year-old females.
