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 …

Oculomotor Task-Switching Performance Improves And Persists Following A Single Bout Of Aerobic Exercise, Diksha Shukla
Electronic Thesis and Dissertation Repository
Executive function includes the core components of response inhibition, working memory, and cognitive flexibility. Interestingly, an accumulating evidence has reported that inhibitory control and working memory improve following a single bout of exercise. It is, however, largely unclear whether cognitive flexibility elicits a similar post-exercise benefit. Accordingly, Chapter Two of my thesis examined whether 20-min of aerobic exercise provides an immediate post-exercise ‘boost’ to cognitive flexibility. Chapter Three examined for how long a putative post-exercise benefit persists. Cognitive flexibility was examined via an AABB task-switching paradigm wherein participants alternated between a well-practiced and a novel oculomotor task pre- and post-exercise. …
