Abstract

This pilot study investigated hemodynamics in bone and muscle of the same leg during resistance exercise, using near-infrared spectroscopy (NIRS). Total (tHb) and oxygenated (O2Hb) hemoglobin increased in bone but decreased in muscle. Absolute peak tHb and O2Hb changes in bone were much smaller than absolute antipeak changes in muscle. Bone tHb and O2Hb reached an initial peak quickly and then decreased progressively; muscle tHb and O2Hb decreased initially and then plateaued. Bone perfusion changes during exercise appear independent of metabolism, suggesting that bone hemodynamics measured using NIRS during resistance training are driven by blood vessel compression and release.
