Muscle oxygen saturation and iliac artery flow limitation with Jem Arnold | EP#358
Manage episode 342877923 series 1382133
Jem Arnold is a physiotherapist, coach and PhD student. Currently, his main research focus is investigating FLIA: blood flow limitation of the iliac artery, a condition that affects certain athletes even at the very elite level, sometimes with surgery as the end outcome. Jem is also very involved and knowledgeable in using NIRS (near-infrared spectroscopy) to measure muscle oxygen saturation (SmO2). We dive deep into how using NIRS and SmO2 can inform workout execution as well as training interventions and athlete profiling.
IN THIS EPISODE YOU'LL LEARN ABOUT:
-What is NIRS and what is muscle oxygen saturation?
-The balance of oxygen delivery (to the capillaries surrounding muscle tissue - supply) and extraction (by the muscles from the capillaries - demand)
-NIRS testing protocols, and how it relates (and does not relate) to oxygen uptake (VO2) and lactate measurments
-Using NIRS to profile athletes
-Using NIRS in high-intensity workouts to optimise interval execution
-Blood flow limitation of the iliac artery (FLIA) - what is it, and what is its prevalence among athletes
-Risk factors for FLIA
-Current detection and diagnosis methods of FLIA, as well as treatment options
-How Jem's research aims to find methods by which FLIA detection can be improved
