A number of submaximal step tests have been developed to predict maximal aerobic capacity. Because step height may influence biomechanical efficiency and heart rate, step tests based on subjects' stature may more accurately predict maximal aerobic capacity. Eighteen women performed the Queens College step test and a modified Queens College step test. The modified step test was performed with the height of the bench set even with the height of the foot at a knee angle of 90 degrees. Analysis of the data indicated a lower recovery heart rate following this test (p < .05). Further, correlations between maximal aerobic capacity and recovery heart rate for both tests were moderate (r = -.80 and -.75, respectively). Our results suggest that step tests based on subjects' stature do not more accurately predict aerobic capacity than those using a standardized bench height.
已经开发了一些亚极量台阶试验来预测最大有氧能力。由于台阶高度可能会影响生物力学效率和心率，基于受试者身高的台阶试验可能更准确地预测最大有氧能力。18名女性进行了皇后学院台阶试验和改良的皇后学院台阶试验。改良的台阶试验是在长凳高度与膝盖角度为90度时的脚的高度齐平的情况下进行的。数据分析表明，在此试验后恢复心率较低（p <.05）。此外，两种试验的最大有氧能力与恢复心率之间的相关性均为中等（分别为r = -.80和-.75）。我们的结果表明，基于受试者身高的台阶试验并不比使用标准化长凳高度的试验更准确地预测有氧能力。
