We developed and validated a graded exercise protocol suitable for operational use on space station. The new treadmill protocol has three level-grade stages (3-min each) at 70, 80, and 90% of estimated VO2peak. The protocol maintains the third stage speed while grade increases each minute to produce work rates equivalent to 100, 107, and 115% of the estimated VO2peak. We compared the new protocol's peak and submaximal responses to those observed during a NASA graded exercise test. All mean protocol differences, including peak work rate (-1.8%), VO2peak (-6.4%), HRpeak (-2.4%), and VEpeak (-9.7%), were not significantly different from the expected measurement errors. We observed similar results for indices (the oxygen uptake at a HR of 150 and the HR's at 70, 80, and 90% of VO2peak) of the submaximal HR-VO2 relationship. The new protocol is an acceptable graded exercise test for periodic operational fitness tests.
我们开发并验证了一种适合在太空站实际操作使用的分级运动方案。新的跑步机方案有三个分级阶段（每个阶段3分钟），强度分别为预计最大摄氧量（VO2peak）的70%、80%和90%。该方案在保持第三阶段速度的同时，坡度每分钟增加，以产生相当于预计VO2peak的100%、107%和115%的工作负荷。我们将新方案的峰值和次最大反应与美国国家航空航天局（NASA）分级运动测试中观察到的结果进行了比较。所有方案的平均差异，包括峰值工作负荷（-1.8%）、VO2peak（-6.4%）、心率峰值（-2.4%）和通气量峰值（-9.7%），与预期测量误差相比均无显著差异。对于次最大心率-摄氧量关系的指标（心率为150时的摄氧量以及VO2peak的70%、80%和90%时的心率），我们也观察到了类似的结果。新方案是用于定期进行操作适应性测试的可接受的分级运动测试。
