The Effect of Working Memory on Corticospinal Excitability
(University of Waterloo, 2020-10-26)Skilled behavior is dependent upon the ability to extract and integrate sensory afference into appropriate output from motor cortex. This process is dynamic with executive control, guided by declarative knowledge (i.e. ... -
Effects of 4-hydroxy-2-nonenal on SERCA pump structure and function in skeletal and cardiac muscle
(University of Waterloo, 2015-11-30)The sarco(endo)plasmic reticulum Ca2+-ATPase (SERCA) pumps are approximately 100 kDa transmembranous proteins that catalyze the ATP-dependent transport of cytosolic Ca2+ [Ca2+]i into the sarcoplasmic reticulum (SR), thereby ... -
The Effects of 60 Days of Head Down Bed Rest on Vascular Health
(University of Waterloo, 2006)This study was designed to test the hypothesis that 60 days continuous head down bed rest (HDBR), an Earth-based analogue of the effects of space flight, would elevate factors that increase vasoconstriction and would ... -
The Effects of a Calcineurin Inhibitor on Muscle Fibre Type and the Pathology of Centronuclear Myopathy in PlnOE Mice
(University of Waterloo, 2017-01-27)The sarco(endo)plasmic reticulum Ca2+ ATPase (SERCA) pump is responsible for pumping calcium from the cytosol back into the lumen of the sarcoplasmic reticulum post contraction. SERCA activity can be reduced by an inhibitory ... -
Effects of a Chronic Mental Stress Intervention Protocol on Vasomotor Function in Common Carotid Artery from Wistar-Kyoto and Spontaneously- Hypertensive Rats
(University of Waterloo, 2017-01-23)ABSTRACT Chronic mental stress is emerging as a cardiovascular disease (CVD) risk factor; however, the underlying physiological mechanisms to explain how chronic mental stress may be causing CVD are still under ... -
The effects of a simulated occupational kneeling exposure on squat mechanics and knee joint load during gait
(Taylor and Francis, 2017-12-01)Occupational kneeling is associated with an increased risk for tibiofemoral knee osteoarthritis. Forces on the knee in the kneeling posture, as well as the greater incidence of meniscus tears among workers, likely contribute ... -
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 a Single Shift of Occupational Childcare on Knee Mechanics during Gait
(University of Waterloo, 2024-04-16)The current literature shows that there are ergonomic challenges in occupational childcare, such as inappropriate heights of furniture for adults, and that childcare educators engage in high knee flexion positions beyond ... -
Effects of Acute Aerobic Exercise on Motor Cortex Plasticity in Individuals With a Concussion History
(University of Waterloo, 2022-11-25)The impact of concussions was previously believed to be transient, however neurophysiological tools have revealed that long-term cognitive and motor declines persist past the acute phase of injury. Through a non-invasive ... -
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 Aging in Reaching and Grasping Movements: A Kinematic Analysis of Movement Context
(University of Waterloo, 2011-04-26)Although several studies have investigated the effects of aging on aspects of motor planning and control, there remains a lack of consensus about the underlying mechanisms responsible for the motor slowing associated with ... -
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 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 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 carbonic anhydrase inhibitors on exercise performance in acute hypoxia
(University of Waterloo, 2024-04-24)Acute mountain sickness (AMS) can occur due to rapid altitude ascents and/or insufficient acclimatization. Acetazolamide (AZ) is commonly prescribed for AMS prophylaxis but appears to inhibit exercise performance. Methazolamide ... -
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 ... -
The Effects of Deprivation Amblyopia on Fixation Stability and Optokinetic Nystagmus
(University of Waterloo, 2024-06-04)Vision and oculomotor control play an essential role in visual perception and motor coordination. Individuals born with unilateral cataracts ultimately develop deprivation amblyopia, which is associated with sensory deficits. ... -
The Effects of Dietary DHA During Development on Maternal Tissue and Spatial Memory in Female and Male Pups During Adolescence
(University of Waterloo, 2019-04-23)Sex differences in plasma docosahexaenoic acid (DHA) status during adulthood have been documented previously, and recent studies suggest the effects of DHA supplementation on human cognition are different in females compared ... -
