Abstract

The use of phase (Φ) data collected in Frequency-Domain Near-InfraRed Spectroscopy (FD-NIRS) has not been widespread in measurements of skeletal muscle and has mainly been applied to measure absolute optical properties. We show that single-distance (SD) Φ has a deeper sensitivity compared to SD intensity (I) and can be more sensitive to oxygen consumption in skeletal muscle underneath superficial adipose tissue. We also show the potential benefit of single-slope (SS) or dual-slope (DS) I or Φ in muscle studies.
