Abstract

The purpose of this study was to evaluate equations of Leger (E1, 1988) and Brewer (E2, 1988) to predict VO2max in Korean adults (158 men and 155 women), and reliability tests were randomly conducted among men (n=90) and women (n=29) in addition to VO2max measurements during a graded exercise treadmill test. Both equations significantly underestimated VO2max compared to those from the treadmill test (p<0.01). A strong intra-class correlation between the treadmill result and 20 m shuttle run test was detected (0.86–0.94, p<0.001). 95 percentile limit of agreement of absolute difference in E1 and E2 in both genders were mostly larger than results from the treadmill test. There was a strong correlation between laboratory test and retest but testing hypothesis of equality of means in men showed significant bias (p=0.003), except difference between test and retest in women (p=0.05). The test and retest of the upper and lower of absolute difference ±95% limit of agreement were −4.86 to −19.05 (men) and 13.61 to 27.91 (women). In conclusion, their equations, based on the results, should not be applied for predicting VO2max in Korean adults.
