There is limited evidence that the nonmotorized treadmill (NMT) test is able to elicit peak power (PP) and mean power (MP) reliably for high-intensity and short-duration exercises in untrained adults. This study aimed to establish the intra- and intersession reliability of PP and MP derived from the NMT test. Nine untrained men and 9 untrained women participated in the study. They completed 2 sessions of a 10-second NMT test on 2 separate occasions that were scheduled 2 weeks apart (intersession test). Each session consisted of 2 sprints (intrasession test). On the third session, the subjects performed two 30-second Wingate Anaerobic Tests. Inter- and intrasession power measurements were analyzed using repeatability coefficient, typical error, coefficient of variation, change in the mean, and Pearson correlation coefficient. Inter- and intrasession measurements using these statistical tests all showed high reliability of the results. The study clearly showed that PP and MP measurements derived from the NMT test was just as reliable as the current "gold standard."
仅有有限的证据表明，对于未经训练的成年人进行的高强度和短时间运动，非机动跑步机（NMT）测试能够可靠地得出峰值功率（PP）和平均功率（MP）。本研究旨在确定源自NMT测试的PP和MP在不同测试时段内及不同测试时段间的可靠性。九名未经训练的男性和九名未经训练的女性参与了该研究。他们在两个不同的场合完成了两次10秒的NMT测试，这两次测试相隔两周（不同测试时段间的测试）。每次测试由两次冲刺（同一测试时段内的测试）组成。在第三次测试中，受试者进行了两次30秒的温盖特无氧测试。使用重复性系数、典型误差、变异系数、均值变化和皮尔逊相关系数对不同测试时段间及同一测试时段内的功率测量结果进行分析。使用这些统计测试进行的不同测试时段间及同一测试时段内的测量结果均显示出结果的高可靠性。该研究清楚地表明，源自NMT测试的PP和MP测量结果与当前的“金标准”一样可靠。
