ACCURACY OF PREDICTION EQUATIONS TO ESTIMATE SUBMAXIMAL VO2 DURING CYCLE ERGOMETRY: THE HERITAGE FAMILY STUDY

1883 The purpose of this study was to: (1) determine the accuracy of equations published by the ACSM (Williams & Wilkins, 5th ed., 1995), Latin and Berg(MSSE, 26: 642, 1994), Lang et al. (MSSE, 24: 272, 1992), and Londeree et al.(MSSE 29:775, 1997) for predicting submaximal VO2 during cycle ergometry; and (2) develop new equations. Subjects (715 males and females from the HERITAGE Family Study, ages 16-65 years) completed 2 submaximal steady-state cycle ergometry trials at 60% of VO2max. The VO2(mean±SD) was 1423±438 ml/min. The table shows a significant difference between each of the published equations and the measured VO2 but no significant difference for the developed New-1. New-1 was cross validated with the “jacknife” method. We conclude that New-1 is an improvement over the other equations.Table
