This is a comparative study of two exercise testing protocols.
The objective of this study was to compare maximal oxygen uptake (VO max) and achieved criteria for maximal exercise testing between the Sunnaas Protocol-a newly designed treadmill exercise test protocol-and the Modified Bruce Protocol in persons with incomplete spinal cord injury (SCI).
This study was conducted in Sunnaas Rehabilitation Hospital, Norway.
Twenty persons (19 men) with incomplete SCI (AIS D) capable of ambulating without assistive devices performed two treadmill walking exercise tests (Sunnaas Protocol and Modified Bruce Protocol) until exhaustion 1-3 days apart. The key differences between the protocols are the smaller increments in speed and shorter duration on each workload in the Sunnaas Protocol. Cardiovascular responses were measured continuously throughout both tests.
The subjects exhibited statistically significantly higher VO max when using the Sunnaas Protocol (37.1±9.9 vs 35.4±9.8 ml kg min, P=0.01), with a mean between-test difference of 1.8 ml kg min (95% confidence interval: 0.49-3.16). There was no significant difference in mean maximal heart rate (HR max). Nineteen (95%) subjects achieved at least three of the four criteria for maximal oxygen uptake using the Sunnaas Protocol. Thirteen (65%) subjects achieved at least three of the criteria using a Modified Bruce protocol.
The small differences in both VO max and achieved criteria in favor of the Sunnaas Protocol suggest that it could be a useful alternative treadmill exercise test protocol for ambulating persons with incomplete SCI.
这是一项对两种运动测试方案的比较研究。
本研究的目的是比较在不完全性脊髓损伤（SCI）患者中，新设计的跑步机运动测试方案——桑纳斯方案与改良布鲁斯方案之间的最大摄氧量（VO₂max）以及达到的最大运动测试标准。
本研究在挪威桑纳斯康复医院进行。
20名（19名男性）能够在无辅助设备情况下行走的不完全性SCI（AIS D级）患者，进行了两次跑步机步行运动测试（桑纳斯方案和改良布鲁斯方案），两次测试间隔1至3天，直至力竭。两种方案的关键差异在于桑纳斯方案中速度增量较小，且每个工作量的持续时间较短。在两次测试过程中持续测量心血管反应。
使用桑纳斯方案时，受试者的VO₂max在统计学上显著更高（37.1±9.9 vs 35.4±9.8 ml kg⁻¹ min⁻¹，P = 0.01），两次测试之间的平均差异为1.8 ml kg⁻¹ min⁻¹（95%置信区间：0.49 - 3.16）。平均最大心率（HRmax）无显著差异。19名（95%）受试者使用桑纳斯方案达到了最大摄氧量四个标准中的至少三个。13名（65%）受试者使用改良布鲁斯方案达到了至少三个标准。
VO₂max和达到的标准方面有利于桑纳斯方案的微小差异表明，它可能是一种适用于能够行走的不完全性SCI患者的有用的替代跑步机运动测试方案。
