Near-infrared spectroscopy (NIRS) has been shown to be one of the tools that can measure oxygenation in muscle and other tissues in vivo. This review paper highlights the progress, specifically in this decade, that has been made for evaluating skeletal muscle oxygenation and oxidative energy metabolism in sport, health and clinical sciences. Development of NIRS technologies has focused on improving quantification of the signal using multiple wavelengths to solve for absorption and scattering coefficients, multiple pathlengths to correct for the influence of superficial skin and fat, and time-resolved and phase-modulated light sources to determine optical pathlengths. In addition, advances in optical imaging with multiple source and detector pairs as well as portability using small wireless detectors have expanded the usefulness of the devices. NIRS measurements have provided information on oxidative metabolism in various athletes during localized exercise and whole-body exercise, as well as training-induced adaptations. Furthermore, NIRS technology has been used in the study of a number of chronic health conditions. Future developments of NIRS technology will include enhancing signal quantification. In addition, advances in NIRS imaging and portability promise to transform how measurements of oxygen utilization are obtained in the future.
近红外光谱（NIRS）已被证明是一种可以测量肌肉和其他组织中氧合作用的工具。本文综述了近十年来在运动、健康和临床科学领域评估骨骼肌氧合和氧化能量代谢方面的进展。NIRS 技术的发展集中在使用多波长来提高信号的定量，以解决吸收和散射系数的问题，使用多个光路来纠正表面皮肤和脂肪的影响，以及使用时间分辨和相位调制光源来确定光程。此外，使用多源和多探测器对的光学成象以及使用小型无线探测器的便携性方面的进步扩大了这些设备的用途。NIRS 测量提供了各种运动员在局部运动和全身运动以及训练诱导适应期间氧化代谢的信息。此外，NIRS 技术已用于许多慢性健康状况的研究。NIRS 技术的未来发展将包括增强信号定量。此外，NIRS 成像和便携性方面的进步有望改变未来获得氧利用率测量的方式。
