The reliability of heart rate responses to non-steady-state tasks among 37 men with spinal cord injuries (lesion level: C4/5-L5) was examined with a simple heart rate recording device (Sport Tester PE3000). Three identical trials of 6 different transfers and an 8-cm curb ascent were performed on one day (Trial 1 and 2; n = 37) and one week later (Trial 3; n = 12). Pearson's r and intraclass correlations for the highest and the mean heart rate provoked during Trial 1 and 2 ranged from 0.73 to 0.97 for the transfers and from 0.92 to 0.97 for the curb ascent. Correlations were somewhat lower for Trial 1 versus Trial 3. A paired t-test revealed lower heart rate responses to Trial 2 and 3, suggesting a moderate learning effect and/or a reduction in psychological stress. It was concluded that heart rate responses to non-steady-state tasks, as recorded by a Sport Tester PE3000, are reproducible in men with spinal cord injuries.
使用一款简单的心率记录设备（运动测试仪PE3000），对37名脊髓损伤男性（损伤平面：C4/5 - L5）在非稳态任务中的心率反应可靠性进行了检测。在一天内进行了3次相同的试验，包括6种不同的转移动作和一次8厘米高的路缘上升试验（试验1和2；n = 37），并在一周后进行了第三次试验（试验3；n = 12）。试验1和2期间诱发的最高心率和平均心率的皮尔逊相关系数r以及组内相关系数，转移动作的范围为0.73至0.97，路缘上升试验的范围为0.92至0.97。试验1与试验3之间的相关性略低。配对t检验显示试验2和3的心率反应较低，表明存在适度的学习效应和/或心理压力降低。得出的结论是，运动测试仪PE3000记录的脊髓损伤男性对非稳态任务的心率反应具有可重复性。
