1. Introduction
Near Infrared Spectroscopy (NIRS) has been used to assess tissue oxygenation (saturation/perfusion), local O2 consumption (VO_ 2), a measure of oxidative metabolism, and blood flow in various human tissues including the brain and skeletal muscle.1,2 Combining NIRS with simple physiological interventions, such as venous or arterial occlusions, allows quantitative measurements to be made from skeletal muscle. This provides a tool for assessing two major determinants of the capacity of muscles to exercise: O2 delivery and O2 utilisation. The non-invasive nature of NIRS makes it an appealing technique for use in a dynamic environment and for activities of daily living. Previous review articles have presented a historical overview of NIRS development.1,2 Between 2007 and 2011 three reviews focused on oxidative metabolism and mitochondrial function in skeletal muscle.3e5 A recent article addressed NIRS instrumentation including its progression to allow nearinfrared cerebral imaging (NIRI) in 2D (topography) and 3D (tomography).6 The extent to which the field has been reviewed highlights the rapid development of instrumentation and methodology and also the importance of continuous re-evaluation of NIRS specific to its application. The purpose of this article is to provide a brief synopsis of recent development in continuous wave (CW) NIRS measurements from skeletal muscle. Discussion centres on its applicability for use in a clinical environment in the context of exercise testing as a means to determine the underlying mechanisms relating to reduced exercise capacity in unhealthy or older individuals. The major limitations of NIRS, suggested methods of circumventing them and assumptions regarding signal components are reviewed. An in depth description of NIRS instrumentation and manufacturer specific variation is not covered as this would be beyond the scope of a short review and can be found elsewhere.1,6
