The effect of aging on movement characteristics and postural control during stooping and crouching tasks
(University of Waterloo, 2013-12-02)Stooping and crouching (SC) postures are integral to many daily tasks, such as retrieving objects from the floor and reaching to low shelves, yet nearly one in four community-dwelling older adults (24%) report having ... -
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 different manual task simulation methods on hand and forearm demand estimates
(University of Waterloo, 2009-08-28)The force exerted during manual tasks is a dominant risk factor for upper-limb musculoskeletal disorders. To identify tasks that may lead to fatigue over a shift, or increase the risk of injury, the demands placed on the ... -
The Effect of Dual-Tasking on Information Processing in Contact Sport Athletes: Examining the long-term effects of Self-reported Concussion
(University of Waterloo, 2015-09-24)Objective: Concussions have been linked to deficits in executive functions including, memory and attention, and oculomotor dysfunction, all of which are required to play safely and successfully at an elite level. The goal ... -
The Effect of Familiarity and Complexity of Environments, and Mode of Wayfinding on Gaze and Memory
(University of Waterloo, 2015-01-21)Whether we travel the well-known route to work or unfamiliar streets in a new city, we use wayfinding in order to determine and follow a route to get to our destination. Wayfinding is dependent on cognitive processes, ... -
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 Minimal Footwear and Midsole Stiffness on Lower Limb Kinematics and Kinetics in Novice and Trained Runners
(University of Waterloo, 2013-09-05)Background: The most common injuries in new or novice runners include medial tibial stress syndrome and patellofemoral pain syndrome; both overuse injuries. It is known that novice runners use a rearfoot strike pattern 98% ... -
The Effect of Mitochondrial Biogenesis on Apoptotic Susceptibility in L6 Myoblasts
(University of Waterloo, 2010-09-27)Mitochondria play an essential role in cell metabolism as well as apoptotic signaling. Chronic endurance exercise has been shown to increase mitochondrial content in skeletal muscle. Interestingly, endurance exercise has ... -
Effects of a single session of aerobic exercise on cognitive function among patients with chronic stroke
(University of Waterloo, 2014-06-09)The incidence of stroke is increasing and is expected to continue to increase with the aging population, escalating rates of obesity and physical inactivity, and the rising prevalence of heart failure. Stroke is a leading ... -
Effects of Age and Experience on Memory-Guided Movements
(University of Waterloo, 2007-09-14)The purpose of the present research was threefold: 1) to investigate whether natural aging affects the movements to remembered targets when participants make reaching movements under closed-loop feedback conditions, 2) to ... -
Effects of Aging in Pointing to Visible and Remembered Targets
(University of Waterloo, 2009-01-22)Most studies that have compared pointing to visible versus remembered targets have involved situations when both the limb and target are present (closed loop-target present), or when both the limb and target are occluded ... -
Effects of Altering the Sequence of a Combined Aerobic and Resistance Exercise Session on Energy Expenditure and Metabolism
(University of Waterloo, 2010-08-25)Despite the known benefits of performing aerobic and resistance exercise independently, the metabolic effects of performing aerobic and resistance exercise in succession, remain unclear. Several studies suggest that the ... -
The Effects of Body Mass Index and Gender on Pelvic Stiffness and Peak Impact Force During Lateral Falls
(University of Waterloo, 2011-09-28)Fall-related hip fractures are a substantial public health issue. Unfortunately, little is known about whether the effective stiffness of the pelvis, a critical component governing impact force during lateral falls, differs ... -
The Effects of Chronic Hydrogen Sulfide Treatment on Hemodynamics and Vasomotor Function in Adult Spontaneously Hypertensive Rats
(University of Waterloo, 2013-04-04)The endothelial layer of blood vessels is able to produce a number of vasoactive substances, and these substances can work to either relax or contract the underlying vascular smooth muscle. A hallmark of hypertension is ... -
Effects of high-fat feeding on skeletal muscle insulin signalling in sarcolipin knockout mice
(University of Waterloo, 2010-08-26)Type II diabetes mellitus (T2DM) has been associated with the onset of diet-induced obesity, which is currently on the rise worldwide. T2DM is typically characterized by insulin resistance in peripheral tissues such as ... -
The effects of Hip Abductor Fatigue on Low Back Pain Development during Prolonged Standing
(University of Waterloo, 2015-08-13)The goal of this thesis was to use hip abductor fatigue to perturb those who do and do not develop pain from standing and determine changes in muscular and postural responses. Forty young healthy participants performed ... -
The effects of safety flooring on sit-to-stand and quiet stance balance reactions in retirement home-dwellers
(University of Waterloo, 2012-10-26)Fall-related injuries in adults over the age of 65 pose an important public health issue especially with an increasing number of older adults living in retirement homes and nursing homes. Safety floors have been developed ... -
Effects of Sarcolipin Ablation on Mitochondrial Enzyme Adaptations to Exercise Training
(University of Waterloo, 2013-01-25)Changes in intracellular Ca2+ ([Ca2+]f) and high-energy phosphates are known to induce adaptive changes in skeletal muscle during endurance exercising training, including mitochondrial biogenesis. Levels of [Ca2+]f are ... -
