n-3 PUFA status in school children is associated with beneficial lipid profile, reduced physical activity and increased blood pressure in boys
(Cambridge University Press, 2013-10-14)Dietary n-3 long-chain PUFA (LC-PUFA) improve dyslipidaemia and hypertension and may affect insulin resistance and adiposity. Increasing numbers of children show signs of the metabolic syndrome (MetS), but few studies have ... -
NADPH Oxidase-dependent ROS Production and Impaired Ca2+ Regulation are Associated with Exercise-induced Cardiac Fatigue in the Rat
(University of Waterloo, 2015-12-10)Cardiac fatigue is a phenomenon that is characterized by a transient reduction in left ventricular contractile and/or relaxation function following acute aerobic exercise. Few studies have utilized rodent models to examine ... -
Negotiating Varying Ground Terrain during Locomotion: Insights into the Role of Vision and the Effects of Aging
(University of Waterloo, 2006-12-18)We continually encounter different ground terrain such as slippery, compliant, uneven, rocky, and irregular terrain when walking, yet we know very little about how individuals safely negotiate this type of complex environment. ... -
Neural control of the healthy pectoralis major from low-to-moderate isometric contractions
(American Physiological Society, 2021-07-01)The pectoralis major critically enables arm movement in several directions. However, its neural control remains unknown. High-density electromyography (HD-sEMG) was acquired from the pectoralis major in two sets of experiments ... -
Neural correlates of trait anxiety in sensory processing and distractor filtering
(University of Waterloo, 2022-10-25)Anxiety, generally defined as an anticipatory heightened state of arousal, has been shown to affect neural markers of cognition and executive components used in sensorimotor function; however, this has infrequently been ... -
The Neural Processes of Perceived Simultaneity and Temporal Order in Younger and Older Adults using EEG.
(University of Waterloo, 2017-08-02)In order to make sense of the world, the central nervous system (CNS) must determine the temporal order of events and integrate cues that belong together. The process of integrating information from multiple sensory ... -
Neuromuscular Control of Gait and Squatting Following a Simulated Occupational Kneeling Exposure
(University of Waterloo, 2016-01-20)Frequent and prolonged occupational high knee flexion postures such as kneeling and squatting are associated with an increased risk for the initiation and development of knee osteoarthritis. In order to reduce the prevalence ... -
Neurophysiological mechanisms of motor cortical modulation associated with bimanual movement
(University of Waterloo, 2008-09-11)The neural correlates of bilateral upper limb movement are poorly understood. It has been proposed that interhemispheric pathways contribute to the modulation of motor cortical excitability during bimanual movements, ... -
New Insights into the Landing Phase of Reactive Stepping: Predictors of Control, Muscle Recruitment, Movement Restraints and Two-Step Responses
(University of Waterloo, 2017-09-27)Preventing falls and fall-related injuries are public health challenges of the upmost importance for Canadians, particularly for older adults. Due to the severe consequences that can accompany a fall (e.g., traumatic brain ... -
Non-pharmacological Management of Osteoporotic Vertebral Fractures: A Qualitative Analysis of Patient and Health-Care Professional Perspectives and Experiences
(University of Waterloo, 2021-09-07)Introduction: Osteoporosis is a chronic disease that is characterized by a femoral neck or lumbar spine bone mineral density (BMD) less than 2.5 standard deviations below the mean of young adult females and encompasses ... -
Normative kinematics of reaching and dexterity tasks: moving towards a quantitative baseline for Functional Capacity Evaluations(FCEs)
(Taylor and Francis, 2017-12-15)Purpose: This work generates a comprehensive description of upper extremity and torso kinematics of a healthy population during reaching and dexterity Functional Capacity Evaluation (FCE) tasks. Methods: Upper limb and ... -
Novel Compliant Flooring Systems from Head to Toes: Influences on Early Compensatory Balance Reactions in Retirement-Home Dwelling Adults and on Impact Dynamics during Simulated Head Impacts
(University of Waterloo, 2011-06-21)The overall goal of my research was to advance our understanding of the potential for novel compliant flooring systems to reduce the risk for fall-related injuries in older adults, including fall-related traumatic brain ... -
Occupational Health Research in Workplaces Transitioning from Modernity to Post-Modernity
(University of Waterloo, 2024-04-11)Occupational health is a complex concept and the offspring of a marriage between law and science. The marriage is influenced by multiple extended families or networks, which act together and in opposition to create policy ... -
Omega-3 Fatty Acid Blood Biomarkers Before and After Acute Fish Oil Supplementation in Men and Women
(University of Waterloo, 2007-09-17)Omega-3 fatty acids, particularly docosahexaenoic (DHA) and eicospentaenoic acid (EPA), are important mediators for cardiovascular disease, fetal/infant development, neurological disorders and inflammatory diseases. ... -
The Organizational Structure and Effectiveness of Canadian National Sport Governing Bodies
(University of Waterloo, 2016-09-15)In this study, voluntary amateur sport organizations were examined from an organizational perspective using Weber's theory of bureaucracy as a conceptual framework. The first purpose was to examine the relationships between ... -
Oxygen uptake and blood flow kinetics following the onset of exercise in trained humans
(University of Waterloo, 2010-10-01)The main hypothesis of this thesis was that the regulation of oxygen uptake (VO2) kinetics at the onset of exercise in trained young men is linked to cardiovascular adaptations. Two studies were conducted to investigate ... -
Participant-Specific Modelling of the Proximal Femur during Lateral Falls: A Mechanistic Evaluation of Risk Factors
(University of Waterloo, 2019-01-10)Falls among older adults are a common occurrence with the potential to result in substantial injury. Hip fractures are among the most frequent and devastating fall induced injuries, resulting in increased morbidity and ... -
Passive Frontal Plane Knee Joint Laxity Following Anterior Cruciate Ligament Reconstruction Within 6 Months to 5 Years
