近红外光谱（NIRS）监测肌肉氧饱和度（SmO 2）正在迅速扩展到应用体育设置。然而，该技术是有限的，因为它无法传达量化的价值。建立了一个测试组合，以评估由市售NIRS设备建模的0%至100%量表的可靠性和有效性。该测试组合应用了一种常用技术，即动脉闭塞法（AOM），以评估重复性、再现性和表面有效性。共有22名参与者完成了测试组合，以仔细检查器械提供的0%至100%量表。所有参与者都在被动和主动条件下进行了重复AOM测试。从AOM中获得SmO 2最小值和SmO 2最大值，并用于后续分析。对重复性和再现性进行了等效性检测，并生成了Bland-Altman图。面效度进行了评估，通过测试血氧饱和度值对一个先验定义的阈值混合静脉血在AOM反应。该设备具有适当的功能0%至100%的规模，在可重复性和再现性方面是可靠的。在测试组合设计中应用的条件下，认为该器械在运动中应用有效。(C)作者。由SPIE在知识共享署名4.0未移植许可下发布。
Near-infrared spectroscopy (NIRS) to monitor muscle oxygen saturation (SmO2) is rapidly expanding into applied sports settings. However, the technology is limited due to its inability to convey quantifiable values. A test battery to assess reliability and validity of a 0% to 100% scale modeled by a commercially available NIRS device was established. This test battery applies a commonly used technique, the arterial occlusion method (AOM) to assess repeatability, reproducibility, and face validity. A total of 22 participants completed the test battery to scrutinize the 0% to 100% scale provided by the device. All participants underwent repeated AOM tests in passive and active conditions. The SmO2 minimum and SmO2 maximum values were obtained from the AOM and were used in the subsequent analysis. Repeatability and reproducibility were tested for equivalency and Bland-Altman plots were generated. Face validity was assessed by testing SmO2 values against an a priori defined threshold for mixed venous blood during AOM response. The device exhibits an appropriately functional 0% to 100% scale that is reliable in terms of repeatability and reproducibility. Under the conditions applied in the test battery design, the device is considered valid for application in sports. (C) The Authors.
