This study compared the W170 scores of 9 male subjects in kgm/kg X min resultant from the following protocols: 2 X 6 min workloads (3 min rest between each bout), 3 X 4 min workloads (1 1/2 min rest between each bout), and 4 X 3 min workloads (1 min rest between each bout). Each subject experienced 2 preliminary rides in order to overcome the problems of learning and habituation and the order of the 3 experimental treatments was randomly assigned to each subject. An analysis of variance repeated measures design revealed that there was no statistically significant difference between the 3 protocols at the 0.05 level. The scores for the three W170 protocols correlated -0.084, 0.040, and -0.142 with VO2 max in ml/kg X min. The correlation coefficient between actual VO2 max in ml/kg X min and that predicted from the Astrand-Ryhming nomogram was 0.723.
本研究比较了9名男性受试者在以下方案下得出的以kgm/kg X min为单位的W170分数：2次6分钟工作量（每次之间休息3分钟）、3次4分钟工作量（每次之间休息1.5分钟）以及4次3分钟工作量（每次之间休息1分钟）。每位受试者都进行了2次初步骑行，以克服学习和适应问题，并且将3种实验处理的顺序随机分配给每位受试者。方差分析重复测量设计显示，在0.05水平上，这3种方案之间没有统计学上的显著差异。这三种W170方案的分数与以ml/kg X min为单位的最大摄氧量（VO2 max）的相关性分别为-0.084、0.040和-0.142。以ml/kg X min为单位的实际最大摄氧量与根据阿斯特兰德-赖明诺模图预测的最大摄氧量之间的相关系数为0.723。
