ACL Injury Mechanisms and the Kinetic Chain Linkage: The effect of proximal joint stiffness on ACL injury risk.
(University of Waterloo, 2016-08-30)Recent literature has suggested that core and gluteal neuromuscular deficits are involved in the mechanism of non-contact ACL injury. Several research groups have identified dynamic valgus of the lower extremity to be an ... -
Acute Cardiac Responses to Respiratory Muscle Unloading at Different Exercise Intensities
(University of Waterloo, 2022-08-29)Respiration is accomplished by alterations in intrathoracic pressure (ITP) and has physiological implications on the heart. For example, the negative ITP during inspiration is transmitted to the right atrium, which augments ... -
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 ... -
Analysis of high and low physical functioning breast cancer survivors within two years of treatment
(University of Waterloo, 2017-08-29)The five year survivorship rate of females diagnosed with breast cancer is 88% across Canada (Canadian Cancer Society, 2015). Often, treatments can cause damage to the tissue which may lead to impairment of upper limb ... -
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 ... -
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 ... -
Assessing pre-existing movement and muscular recruitment differences in prolonged standing, transient low back pain developers compared to non-pain developers
(University of Waterloo, 2018-09-26)Epidemiological studies have reported occupational prolonged standing to be associated with low back pain (LBP). Studies that have conducted simulations of prolonged standing work in healthy individuals have demonstrated ... -
Assessing Workers’ Ability to Recognize Lifting Risk Factors for Low Back Pain: Investigating the Efficacy of a Simple Educational Message.
(University of Waterloo, 2015-12-21)Introduction: Participatory ergonomic approaches have been shown to be an effective method for identifying work place hazards. Since in many workplaces, expertise in ergonomics is not available, simple educational messages ... -
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 ... -
The Association between Fractures, Posture and Physical Performance Measures in Women Over the Age of 65
(University of Waterloo, 2016-10-06)Background Information: Vertebral fractures are a common type of osteoporotic fracture, associated with increased morbidity and mortality. An accumulation of vertebral fractures may lead to postural changes including ... -
Attention and Age-Related Components of Visual-Tactile Modulation of Somatosensory Cortex and Motor Implications
(University of Waterloo, 2010-06-16)Successful interaction with the external world requires continual sensory detection, sensorimotor translations and goal-directed motor execution. Attention to task-relevant stimulation can facilitate sensory detection and ... -
Autophagy Regulates the NOTCH Signaling Pathway During Skeletal Muscle Cell Differentiation
(University of Waterloo, 2021-06-01)Research has indicated a crucial role for autophagy during skeletal muscle differentiation. More so, the inhibition of autophagy using 3MA (3-methyladenine), CQ (chloroquine), and shRNA against Atg7 has been shown to impair ... -
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 ... -
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 ... -
Cardiac motion simulation in cadavers and carotid artery longitudinal wall behaviour
(University of Waterloo, 2023-12-21)Carotid artery longitudinal motion (CALM) is a bidirectional, multiphasic motion of the intima-media complex of the common carotid artery (CCA) wall. This motion has exhibited changes with aging, elevated cardiovascular ... -
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 ... -
Cause or Consequence? The Interrelationship Between Physical Activity and Fractures
(University of Waterloo, 2021-08-30)Our study characterized the physically active and non-active circumstances during which fractures occur and explored long-term effects on physical activity following one or more fractures of the hip or pelvis, spine, upper ... -
Central Nervous System Control of Dynamic Stability during Locomotion in Complex Environments
