NIR spectroscopy allows monitoring of muscle oxygenation and perfusion during contraction. The knowledge of modifications of blood characteristics in body tissues has relevant clinical interest. A compact and reliable device, which makes use of two laser diodes at 750 and 810 nm coupled with the skin surface through optical fibres, was tested. NIR and surface EMG signals during isokinetic contractions were studied. A set of parameters was analysed in order to obtain information about metabolic modifications during muscle fatigue.
