The authors' modification of the Astrand-Rhyming Cycle Ergometer Test is of short duration, has low initial and peak work rates and was in an earlier study applied for population fitness testing (N = 587) at a survey center after other cardiovascular risk factor measures were obtained in the home. To add fitness testing in the home, the authors have designed a safe, brief 10 inch (25.4 cm) high step test for estimating maximal oxygen uptake (VO2max). Measured maximal oxygen uptake for step tests has been shown to be approximately 10% higher than that reported for cycle tests. All test instructions and stepping rates were included on a cassette tape; heart rates were monitored by a digital tachograph during the last 30 seconds of stepping. Maximal oxygen uptake was measured directly on a bicycle, estimated by the step test, and measured by the authors' bike test in 48 men and women aged 19-70 years who took part in a community fitness program in Pawtucket, Rhode Island in January-February 1983. No significant differences in maximal oxygen uptake were found between the bicycle protocols. The step test estimate of maximal oxygen uptake (VO2max) was significantly higher (12%) than directly measured VO2max, reflecting the expected difference between stepping and cycling. The correlation between direct and both estimates was 0.92. The cross-validation correlation between the estimates was 0.98. The authors' protocol provides accurate estimates of maximal oxygen uptake and is safe and suitable for in-the-home assessment of fitness of people aged 19-70 years for epidemiologic studies.
作者对阿strand - 莱明循环测力计测试的改进持续时间短，初始和峰值工作率低，并且在早期一项研究中，在家庭中获取了其他心血管危险因素测量值之后，于一个调查中心用于人群健康测试（N = 587）。为了在家庭中增加健康测试，作者设计了一种安全、简短的10英寸（25.4厘米）高的台阶测试，用于估计最大摄氧量（VO2max）。已表明台阶测试测得的最大摄氧量比循环测试报告的数值约高10%。所有测试说明和踏频都包含在盒式磁带上；在踏台阶的最后30秒内，通过数字转速表监测心率。1983年1月至2月，在罗德岛州波塔基特参加社区健身项目的48名年龄在19 - 70岁的男性和女性中，直接在自行车上测量最大摄氧量，通过台阶测试进行估计，并通过作者的自行车测试进行测量。在自行车测试方案之间，未发现最大摄氧量有显著差异。台阶测试对最大摄氧量（VO2max）的估计值显著更高（高12%），这反映了踏台阶和骑自行车之间预期的差异。直接测量值与两种估计值之间的相关性为0.92。两种估计值之间的交叉验证相关性为0.98。作者的方案能够准确估计最大摄氧量，并且安全且适合在家庭中对19 - 70岁人群进行流行病学研究的健康评估。
