Near-infrared spectroscopy is currently used to assess changes in the oxygen saturation of the muscle during exercise. The primary purpose of this study was to assess the reliability of near-infrared spectroscopy in determining muscle oxygen saturation (StO2) in the vastus lateralis during cycling and the gastrocnemius during running for exercise intensities at lactate threshold and maximal effort. Test-retest reliability was determined from an intraclass correlation coefficient obtained from a one-way analysis of variance. Reliability of muscle StO2 for the gastrocnemius at lactate threshold was R = .87, and R = .88 at maximal effort. Reliability of muscle StO2 for the vastus lateralis at lactate threshold was R = .94 and R = .99 at maximal effort.
近红外光谱目前用于评估运动期间肌肉氧饱和度的变化。本研究的主要目的是评估近红外光谱在确定骑行时股外侧肌以及跑步时腓肠肌在乳酸阈值和最大运动强度下的肌肉氧饱和度（StO2）方面的可靠性。通过单向方差分析得到的组内相关系数来确定重测可靠性。腓肠肌在乳酸阈值时肌肉StO2的可靠性为R = 0.87，在最大运动强度时为R = 0.88。股外侧肌在乳酸阈值时肌肉StO2的可靠性为R = 0.94，在最大运动强度时为R = 0.99。
