Human muscle oxygenation during exercise was studied with near - infrared spectroscopy (NIRS). Ten athletes performed a 12 min aerobic cycling exercise with increasing workloads. Muscle oxygen content (OC), blood lactate (Bla) and heart rate (HR) were measured continuously throughout the test. The values measured showed a linear correlation (r = -0.962) between Bla and OC during aerobic exercise. The athletes and controls were also selected to compare the variation of OC, Bla and HR under exercise of the same workload. In addition, the muscle oxygen decrease and recovery during sprint were determined and discussed. The results demonstrated that NIRS provides an advantageous method for evaluation of oxygen supply and consumption in working muscles during exercise of varying intensity.
利用近红外光谱技术（NIRS）对运动过程中的人体肌肉氧合情况进行了研究。10名运动员进行了12分钟的有氧自行车运动，运动负荷逐渐增加。在整个测试过程中持续测量肌肉氧含量（OC）、血乳酸（Bla）和心率（HR）。所测值显示有氧运动期间Bla与OC之间呈线性相关（r = -0.962）。还选取了运动员和对照组来比较相同工作负荷运动下OC、Bla和HR的变化。此外，还测定并讨论了短跑过程中肌肉氧的减少和恢复情况。结果表明，NIRS为评估不同强度运动期间工作肌肉的氧供应和消耗提供了一种有利的方法。
