Abstract
The velocity (vVO2max) associated with VO2max has been proved to be correlated with performance. The purpose of the study was to validate the field test of vVO2max, 5-min running test proposed by Bethon(1997), in predicting individual aerobic capacity. Twenty male running athletes and sedentary people (23.65 ± 5.86 yrs) were recruited in this study. The subjects participated in four tests including Bruce test for VO2max, 5mile/h steady speed test for running economy,5min running test and 1 mile walk/run test. The athletes' performance of 1500m, 3000m, 5000m, 10000m were also recorded. Pearson's moment product correlation and stepwise regression analysis revealed that the vVO2max was highly correlated with VO2max (r = 0.93, p < .05) as well as 1 mile walk/run test (r = 0.91, p < .05) and different distance performances. The VO2max in 5mile/h running test in treadmill was also correlated with VO2max (r = 0.48, p < .05). The regression equation was developed as following: VO2max (ml/kg/min) = 14.96 VO2max · 4.68, SEE = 4.65ml/kg/min, R2 = 0.87. These results suggest that: 1) In subjects of different fitness levels, people with higher VO2max could run more economically; 2) vVO2max not only well-evaluate individual aerobic capacity but also effectively predict the performance of different distances.
