Abstract

The monitoring of a single muscle location does not reflect the heterogeneity of the muscle groups activation during exercise. In the past, measurements of oxygen consumption (VO₂) at single muscle locations could be carried out non-invasively by near-infrared continuous wave spectroscopy (NIR_CWS) at rest or during isometric contractions. In the present study, human regional quadriceps (vastus lateralis and rectus femoris) VO₂ was investigated at rest and during maximal voluntary contractions using a 12- channel NIR_CWS system with an acquisition time of 0.1 s.
