The Acute Effect of Exercise Intensity on Cognitive Function
(University of Waterloo, 2016-08-30)Recent research has found that regular exercise has a positive effect on cognitive function. Some studies indicate that even an acute session of exercise has a slight positive effect on cognitive function, though factors ... -
Acute Regulation of Na+-K+-ATPase Activity in Skeletal Muscles of Different Fibre Type Composition in Response to Insulin Exposure
(University of Waterloo, 2008-01-09)The Na+-K+-ATPase (pump) is a transmembrane, multi-subunit (α and β) protein that is expressed in all cells, and particularly in skeletal muscle cells. In one cycle, it pumps 3 Na+ ions out of the cell and 2 K+ ions into ... -
Acute Regulation of Vascular Tone by AMP-activated Protein Kinase in Arteries of Healthy, Hypertensive and Aged Rats
(University of Waterloo, 2011-12-21)Background, Rationale and General Purpose: Several seminal observations suggest that AMPK mediates vascular tone: 1) in endothelial cell culture and in vitro isolated protein experiments, activation of AMPK stimulates ... -
Age-related changes in the control of mediolateral dynamic stability during volitional and reactive stepping
(University of Waterloo, 2012-04-23)The high incidence of falls and fall-related injuries among Canadians over the age of 65 continues to be a key public health issue. As the current proportion of individuals within this cohort of the population is predicted ... -
Analysis of the effect of rotator cuff impingements on upper limb kinematics in an elderly population during activities of daily living
(University of Waterloo, 2010-02-18)Despite a large prevalence of rotator cuff impingements or tears in the elderly population, little research has focused on understanding how this population adapts to perform tasks of daily living. Past research has focused ... -
Analysis of Transcranial Doppler Ultrasound Waveform Morphology for the Assessment of Cerebrovascular Hemodynamics
(University of Waterloo, 2012-08-29)The use of transcranial Doppler (TCD) ultrasound for the assessment of cerebral blood flow velocity (CBFV) provides an indication of cerebral blood flow assuming the diameter of the insonated vessel remains constant. Studies ... -
Apoptotic signalling and structural alterations in autophagy-deficient murine skeletal muscle
(University of Waterloo, 2014-10-15)Autophagy is a catabolic process by which the cell targets and degrades cytoplasmic materials, such as proteins and organelles. Autophagy is required for the control of muscle mass under catabolic conditions, but is also ... -
An Assessment of the Interplay between the Shoulders and the Low Back in Occupational Tasks: A Manual Patient Handling Example
(University of Waterloo, 2010-12-16)Redundancy and variation are characteristics of humans. Many muscles contribute to producing a movement at a joint, allowing different strategies for task performance. Further, the shoulders and back are involved in many ... -
Axial twist loading of the spine: Modulators of injury mechanisms and the potential for pain generation.
(University of Waterloo, 2008-05-26)There are several reasons to research the effects of axial twist exposures and the resulting loading on the spine. The lack of consensus from the limited work that has previously examined the role of axial twist moments ... -
Biomechanical Assessment of Cycling Helmets: the Influence of Headform and Impact Velocity based on Cycling Collisions associated with Injury Claims
(University of Waterloo, 2015-01-23)The goal of my thesis was to fill some of the gaps in knowledge about cyclist/motor vehicle collisions and testing guidelines for cycling helmets. Cycling collisions with motor vehicles represent a problem for the Canadian ... -
A biomechanical investigation into the link between simulated job static strength and psychophysical strength: Do they share a “weakest link” relationship?
(University of Waterloo, 2011-01-17)Maximum voluntary forces and psychophysically acceptable forces are often used to set force guidelines for exertions as a means to protect against overexertion injuries in the workplace. The focus of this dissertation was ... -
Biomechanical Predictors of Functionally Induced Low Back Pain, Acute Response to Prolonged Standing Exposure, and Impact of a Stabilization-Based Clinical Exercise Intervention
(University of Waterloo, 2009-07-24)Purpose: Biomechanical differences between people with low back pain (LBP) and healthy controls have been shown previously. LBP has been associated with standing postures in occupational settings. A transient pain-generating ... -
Biomechanics of Lateral Hip Impacts: the Influence of Measurement Technique and Contact Area
(University of Waterloo, 2014-02-21)The experiments presented in this thesis provide novel insight into two scarcely studied areas in the field of lateral hip impact biomechanics. The high energy nature of hip impacts requires high sampling rates for accurate ... -
Can Altering Hip Joint Fluid Volume and Intra-Capsular Pressure Influence Muscle Activation Patterns? Neuromuscular Implications on Clinical Practice
(University of Waterloo, 2011-05-03)Although the integrated relationship that exists between the lumbar spine and hip joints is frequently acknowledged in scientific journals and by medical professionals, specific functional and injury relationships, are ... -
Cardiovascular Deconditioning Resulting from 28-hour Bed-rest and the Efficacy of the Fluid Loading Countermeasure
(University of Waterloo, 2010-01-11)This study tested the hypotheses that 1) 28h head-down bed-rest (HDBR) would result in significant hypovolemia and cardiovascular deconditioning, and that 2) NASA’s fluid loading protocol (ingestion of 15 ml/kg water with ... -
Cardiovascular responses of women to orthostatic stress, the effects of the menstrual cycle and age, and a comparison to men
(University of Waterloo, 2010-08-10)Young women are known to exhibit a greater incidence of orthostatic hypotension than men. The exact mechanisms for this are unclear and it has been proposed to be related to cardiac filling, peripheral resistance, and/or ... -
Cerebrovascular and cardiovascular responses to lower body negative pressure and posture change in the elderly
(University of Waterloo, 2012-08-27)Lower body negative pressure (LBNP) is frequently used in the research setting as a means to induce orthostatic stress. This tool is applicable to typical movements during daily living only if the associated responses are ... -
Changes in Conduit Artery Blood Flow and Diameter Post Blood Flow Restriction
(University of Waterloo, 2011-04-19)Flow mediated dilation (FMD) is a non-invasive test that assesses endothelial health and nitric oxide bioavailability; it is commonly used to examine changes in vascular health due to disease or de-conditioning. Currently, ... -
Changes in Physical Activity, Physical Function and Cognitive Function with Transition to Retirement Living
(University of Waterloo, 2014-08-01)Physical activity is associated with slower physical and cognitive decline with aging. However, there are many barriers to physical activity among community-dwelling older adults. Retirement living may facilitate physical ... -
