在过去的15年里，由于包括近红外光谱(NIRS)在内的非侵入性技术的逐步引入，运动医学中对人体肌肉能量学的研究发生了根本性的变化。近红外线(700-1000纳米)穿透皮肤、皮下脂肪和下层肌肉，并被(氧合和脱氧)血红蛋白吸收或散布在组织内。近红外光谱是一种非侵入性且成本相对较低的光学技术，正在成为一种广泛使用的测量肌肉氧饱和度和血红蛋白体积变化的仪器。肌肉O(2)饱和度代表了毛细血管、小动脉和静脉床等小血管中O(2)供应和消耗之间的动态平衡。NIRS的优势在于，与(31)P-磁共振波谱相比，对肌肉性能的限制更少，并且更舒适，更适合于高时间分辨率(高达10赫兹)的多个肌群的监测。本文就近红外光谱的仪器和测量参数、近红外光谱在肌肉运动生理学中的作用及其在运动医学中的应用作一综述。报道了近红外光谱测量在骨骼肌休息和锻炼中的优点和存在的问题。多项研究的结果表明，近红外光谱是一种成功应用于运动医学的有力工具。近红外光谱可以客观地评估运动员的肌肉氧化代谢及其在潜在的治疗策略和特定的训练计划后的修改。
In the last 15 years the study of the human muscle energetics in sports medicine underwent a radical change thanks to the progressive introduction of non-invasive techniques, including near infrared (NIR) spectroscopy (NIRS). NIR light (700-1000 nm) penetrates skin, subcutaneous fat and underlying muscle, and is either absorbed (by oxy- and deoxy-haemoglobin) or scattered within the tissue. NIRS is a non-invasive and relatively low cost optical technique that is becoming a widely used instrument for measuring muscle O(2) saturation and changes in haemoglobin volume. Muscle O(2) saturation represents a dynamic balance between O(2) supply and O(2) consumption in the small vessels such as the capillary, arteriolar and venular bed. NIRS offers the advantage of being less restrictive than (31)P-magnetic resonance spectroscopy with regard to muscle performance and more comfortable and suitable for the monitoring, with high temporal resolution (up to 10 Hz), of multiple muscle groups. The aim of this review is to summarise the NIRS instrumentation and the measurable parameters, the role of NIRS in muscle exercise physiology, and the applications in sports medicine. The advantages and the problems of NIRS measurements, in resting and exercising skeletal muscles, are reported. The results of several studies suggest that NIRS is a powerful tool for being applied successfully in sports medicine. NIRS can objectively evaluate muscle oxidative metabolism in athletes and its modifications following potential therapeutic strategies and specific training programs.
