There is a need for simple and feasible methods for estimation of cardiorespiratory fitness (CRF) in large study populations, as existing methods for valid estimation of maximal oxygen consumption are generally time consuming and relatively expensive to administer. The Danish step test may be a feasible alternative for estimation of VO2max.
To compare a simple fitness test, the Danish step test, to an indirect maximal test, the watt-max test, for estimation of VO2max.
In the population-based Health2008 study, 2218 men and women aged 30-60 years were invited. Altogether, 795 eligible participants (response rate 35.8%) performed the watt max and the Danish step test. Correlation and agreement between the two VO2max test results was explored by Pearson's rho, Bland-Altman plots, Kappa(w), and gamma coefficients.
The correlation between VO2max (ml/kg/min) estimated by the two tests was moderate to high (men: r = 0.69, p < 0.0001; women: r = 0.77, p < 0.0001). The Danish step test slightly overestimated VO2max compared to the watt-max test, more so in women than in men. Agreement between the two tests when VO2max was classified in five levels was gamma = 0.77, Kappa(w )= 0.42 in women, and gamma = 0.64, Kappa(w )= 0.37 in men.
The Danish step test is a safe and feasible alternative to the more time-consuming watt-max test as a method for estimation of VO2max in large adult population-based studies.
在大型研究人群中，需要简单可行的方法来评估心肺功能（CRF），因为现有的最大摄氧量的有效评估方法通常比较耗时且相对昂贵。丹麦台阶测试可能是评估 VO2max 的可行替代方法。
比较简单的体能测试——丹麦台阶测试和间接最大测试——瓦特最大测试，以评估 VO2max。
在基于人群的 Health2008 研究中，邀请了 2218 名 30-60 岁的男性和女性。共有 795 名符合条件的参与者（响应率为 35.8%）进行了瓦特最大和丹麦台阶测试。通过 Pearson's rho、Bland-Altman 图、Kappa(w)和 gamma 系数探讨了两种 VO2max 测试结果之间的相关性和一致性。
两种测试方法估计的 VO2max（ml/kg/min）之间的相关性为中度到高度（男性：r=0.69，p<0.0001；女性：r=0.77，p<0.0001）。与瓦特最大测试相比，丹麦台阶测试略微高估了 VO2max，在女性中比男性更明显。当 VO2max 分为五个水平时，两种测试的一致性为 gamma=0.77，Kappa(w)=0.42（女性）和 gamma=0.64，Kappa(w)=0.37（男性）。
丹麦台阶测试是一种比更耗时的瓦特最大测试更安全且可行的替代方法，可用于大型成人人群研究中评估 VO2max。
