Development of a Wearable Sensor-Based Framework for the Classification and Quantification of High Knee Flexion Exposures in Childcare
(University of Waterloo, 2022-12-19)Repetitive cyclic and prolonged joint loading in high knee flexion postures has been associated with the progression of degenerative knee joint diseases and knee osteoarthritis (OA). Despite this association, high flexion ... -
The Dilemma of Proxy-Agency in Exercise: a Social-Cognitive Examination of the Balance between Reliance and Self-Regulatory Ability
(University of Waterloo, 2005)Social Cognitive Theory (SCT: Bandura, 1997) has been used successfully in understanding exercise adherence. To date, the majority of the exercise research has focused on situations of personal agency (i. e. , self ... -
Does sex or exercise modality influence post-exercise glucose handling or insulin sensitivity?
(University of Waterloo, 2022-09-20)Exercise has long been recognized for its beneficial effects on glucose handling in both insulin sensitive and insulin resistant populations. However, there is conflicting evidence in regards to the best type and duration ... -
Dual-task effects of concurrently coupling aerobic exercise with virtual navigation
(University of Waterloo, 2021-03-01)Aerobic exercise is a modifiable lifestyle factor that is important for maintaining or improving both physical health and brain health. Maintaining or improving executive function throughout the lifespan is a prominent ... -
Effect of arterial blood perfusion pressure on vascular conductance and muscle blood flow at rest and exercise
(University of Waterloo, 2012-05-01)The adaptations of vessel diameter represented by vascular conductance (VC), muscle blood flow (MBF) and oxygen delivery (DO2est) were investigated during rest and exercise using the effects of gravity to manipulate ... -
The effect of concussion history on relevancy-based gating of visual and tactile stimuli
(University of Waterloo, 2018-01-23)At the cortical level, incoming sensory inputs are subject to interruption as they are transmitted to modality-specific cortical areas, in order to prevent excessive processing of task-irrelevant sensory information and ... -
The effect of limited hip mobility on the lumbar spine in a young adult population
(University of Waterloo, 2010-08-26)Limited hip mobility is known to affect the lumbar spine. Much of the previous research has utilized a participant population whose hip mobility is compromised due to arthritic or neurological dysfunctions. Such aetiologies ... -
The Effect of Spironolactone on Cerebral Blood Flow and Cognition
(University of Waterloo, 2018-03-23)Hypertension and arterial stiffness are associated with structural and functional changes in cerebral circulation and cognitive function, but based on existing evidence the effects are potentially reversible by spironolactone ... -
The effects of body composition and body configuration on impact dynamics during lateral falls: insights from in-vivo, in-vitro, and in-silico approaches
(University of Waterloo, 2017-10-24)Fall-related injuries are the current leading accidental cause of emergency room and hospital visits, hospitalizations, and injury-related deaths in Ontario. Hip fractures in particular are associated with poor functional ... -
The effects of physical exercise on cognition of individuals with Parkinson’s disease
(University of Waterloo, 2016-05-13)Despite motor symptoms being the hallmark of Parkinson’s disease (PD), cognitive decline has been shown to affect a large proportion of individuals with PD throughout the course of disease progression. Deficits in cognition ... -
Endothelium-dependent vasomotor responses of hypertensive and type 2 diabetic rats: effects of sex, ageing, and therapeutic interventions
(University of Waterloo, 2009-08-26)Impaired endothelial vasomotor function is a hallmark of many chronic disease states, including essential hypertension and type 2 diabetes mellitus. Loss of the homeostatic role of the endothelium in large conduit arteries ... -
Evaluation of Conventional and Novel Dietary Strategies to Promote Intake of Omega-3 Highly Unsaturated Fatty Acids
(University of Waterloo, 2012-09-27)Intakes of the highly unsaturated fatty acids (HUFA, ≥20 Carbons, ≥3 double bonds) eicosapentaenoic acid (20:5n-3; EPA) and docosahexaenoic acid (22:6n-3, DHA) greater than 0.25 g/d are currently recommended for health ... -
Examination of Healthy Neuromusculoskeletal Control of the Pectoralis Major Muscle
(University of Waterloo, 2020-10-29)The pectoralis major, a large, multipennate muscle, assists in shoulder complex mobility and stability. Although its highly intricate architectural properties allow it to contribute to many upper extremity tasks, its exact ... -
Examination of mechanisms underlying the effect of single-session exercise on cortical plasticity
(University of Waterloo, 2018-10-10)Individuals who routinely participate in physical activity are the beneficiaries of a wide array of health benefits. As well, recent observations in humans have identified that even a single session of aerobic exercise can ... -
Examining Autophagy and Mitophagy as Inducible Mechanisms of Cellular Remodelling
(University of Waterloo, 2017-11-20)Despite an explosion of knowledge regarding the molecular regulation of autophagy since its initial characterization in yeast in the 1990s (including the 2016 Nobel Prize in Physiology or Medicine for Dr Yoshinori Ohsumi), ... -
Examining behavioural and electrophysiological markers of mental workload in individuals with and without a history of concussion
(University of Waterloo, 2021-08-19)Objectives: The goal of this thesis was to examine the neurocognitive mechanisms of mental workload for the purpose of improving our knowledge of the long-term effects of concussion. Four experiments were performed ... -
