Quantifying The Inter-Relationships Amongst Muscle Blood Flow, O2 Uptake And Muscle Deoxygenation Kinetics From Elevated Baseline Metabolic Rates And Increasing Work Rate Amplitudes, Lorenzo Love
Electronic Thesis and Dissertation Repository
Upon an instantaneous increase in work rate (WR), pulmonary O2 uptake (V̇O2p) increases in an exponential-like manner towards a new steady-state. To support this increase in V̇O2p there is an increase in blood flow (BF; O2 delivery) to the muscle. Previous research has shown that the rate of this increase in V̇O2p (which defines V̇O2p kinetics) becomes progressively slower with increasing baseline WR (WRbl). Given the paucity of research on blood flow dynamics and underlying muscle metabolic rate, this thesis examined the effect of metabolic rate on the dynamics and relationships …
