Near infrared spectroscopy (NIRS) has been frequently used to assess intra-muscular oxygenation past few decades. In recent years, refinement of NIRS hardware and algorithms used to convert changes in optical absorption to changes in concentration improved the validity of oxygenated haemoglobin (HbO2), deoxyhaemoglobin (Hb), myoglobin (Mb) and the oxidised copper compound of cytochrome aa3 , (cyt aa3 ) measurements. Subsequently, the use of NIRS to study the muscle oxygenation profiles during various types of exercise and to monitor differences in oxygenation levels in patients under various pathological conditions is being increased. It would be thought-provoking to combine future muscle studies with MRS and/or electromyography techniques to improve the understanding of intramuscular oxygenation.
在过去几十年里,近红外光谱技术(NIRS)一直被频繁用于评估肌肉内的氧合情况。近年来,NIRS硬件以及用于将光吸收变化转换为浓度变化的算法得到了改进,提高了对氧合血红蛋白(HbO2)、脱氧血红蛋白(Hb)、肌红蛋白(Mb)以及细胞色素aa3的氧化铜化合物(cyt aa3)测量的有效性。随后,NIRS在研究各类运动过程中的肌肉氧合情况以及监测各种病理状态下患者氧合水平差异方面的应用正在增加。将未来的肌肉研究与磁共振波谱(MRS)和/或肌电图技术相结合,以增进对肌肉内氧合的理解,这将是发人深省的。
