Functional near-infrared spectroscopy (fNIRS) long channels signals are contaminated by motion artifacts and extra-cerebral tissues activity during motor production. In this study, we aimed at quantifying these limitations using an fNIRS continuous-wave system during whole-body movement (i.e., cycling task). Using motion-capture recordings, physiological monitoring and short channels, our results showed a high stability of the headset during whole-body movements production and demonstrated the ability of short channels to capture physiological extra-cerebral activity.
