Self-efficacy theory and the self-regulation of exercise behaviour
(University of Waterloo, 2005)Why are people unable to adhere to an exercise program? Adhering to an exercise program is complex, and exercisers struggle with a variety of challenges that require self-regulation (e. g. , making time, learning skills, ... -
Sensory Conflict: Effects on the Perceived Onset of Motion and Cybersickness in Virtual Reality
(University of Waterloo, 2023-01-03)The perception of self-motion involves the integration of multisensory information, however there are scenarios in which the sensory feedback we receive from these different sources can conflict with one another. For ... -
Sensory information to motor cortices: Effects of motor execution in the upper-limb contralateral to sensory input.
(University of Waterloo, 2009-09-29)Performance of efficient and precise motor output requires proper planning of movement parameters as well as integration of sensory feedback. Peripheral sensory information is projected not only to parietal somatosensory ... -
Sex-based differences in IMCL storage and utilization during an acute bout of high intensity interval exercise (HIIE)
(University of Waterloo, 2023-09-21)INTRODUCTION: The contribution of lipids, particularly intramyocellular lipids (IMCL), to energy production during high intensity interval exercise (HIIE) is not well characterized. Sex influences lipid utilization during ... -
Social Factors and Nutrition Risk in Community-Living Seniors During the COVID-19 Pandemic
(University of Waterloo, 2023-01-04)Pandemic countermeasures (e.g., lockdown, restrictions) enacted to minimize the spread of COVID-19 may put older adults at nutrition risk. This thesis uses an online/telephone survey to investigate factors associated with ... -
Soft Tissue Thickness and Composition surrounding the Proximal Femur
(University of Waterloo, 2023-08-17)Introduction: In Canada, approximately 30 000 hip fractures occur each year. Hip fractures are associated with significant morbidity, mortality, and quality of life changes. Trochanteric soft tissues have been shown to ... -
Spine Biomechanics of Prolonged Sitting: Exploring the Effect Chair Features, Walking Breaks and Spine Manipulation have on Posture and Perceived Pain in Men and Women.
(University of Waterloo, 2015-03-03)Purpose: Prolonged sitting while working in an office has become a standard function in our society. While seated postures do conserve energy and permit a worker to focus on a task, the posture also involves a significant ... -
Stabilization Strategies of the Lumbar Spine in Vivo
(University of Waterloo, 2002)In developing a method of quantifying stability in the lumbar spine Cholewicki and McGill (1996) have also broached the notion of sufficient stability, where too much stiffness (and stability) would hinder motion. Thus ... -
Statistical Power in Ergonomic Intervention Studies
(University of Waterloo, 2010-04-21)As awareness of the costs of workplace injury and illness continues to grow, there has been an increased demand for effective ergonomic interventions to reduce the prevalence of musculoskeletal disorders (MSDs). The goal ... -
Strategies and Adaptations Seen with Unilateral Lower Limb Weighting during Level Ground Walking and Obstacle Clearance Tasks
(University of Waterloo, 2010-02-17)Abstract: Previous lower limb weighting studies have placed a load on the legs bilaterally and tested different placement locations. It was previously determined that kinematic changes occur with greater masses and at ... -
Strategies Utilized while Minimizing Ankle Motion Bilaterally and Unilaterally during Level Ground Walking and Obstacle Clearance Tasks
(University of Waterloo, 2010-08-30)A great deal of research has been done on the adaptive strategies of individuals who have been affected by a gait altering ailment, but there is little research on the adaptive strategies to imposed restrictions in the ... -
Studies on the Physiology and Glucose Metabolism of 14-16-Month-Old Female RTSAKO Mice
(University of Waterloo, 2020-09-01)Obesity is a global epidemic. Characterized by an imbalance between energy intake and expenditure, the metabolic and physiological dysfunctions that it yields can result in other diseases such as diabetes. Although several ... -
The suitability and consequence of renal tubule specific adipose triglyceride lipase ablation for the study of targeted lipid accumulation in the kidney
(University of Waterloo, 2015-05-15)Circulating non-esterified fatty acids (NEFA) rise during fasting and are taken up by the kidneys, either directly from the plasma or during re-uptake of albumin from glomerular filtrate, and are stored as triacylglycerol ... -
Supramaximal Testing to Confirm the Achievement of V̇O2max in Acute Hypoxia
(University of Waterloo, 2023-01-23)Incremental exercise tests are often used to quantify an individual’s maximal oxygen uptake (V̇O2max). To confirm V̇O2max, a bout of supramaximal exercise can be performed after maximal exercise and if V̇O2 is within the ... -
Tailored Exercise For Fall And Fracture Prevention In Older Adults: A Family Health Team Approach
(University of Waterloo, 2012-09-27)Background: Exercise interventions reduce falls in older adults. Methods for enhancing uptake and adherence to exercise programs in at-risk individuals are needed. Objectives: This pilot study evaluated feasibility of ... -
Theta-burst rTMS over SI modulates tactile perception on the hand
(University of Waterloo, 2011-05-18)Fine motor control of the hand relies on intact somatosensory integration and feedback. Impaired hand movements are observed in patient groups where touch perception and processing within the primary somatosensory cortex ... -
Thigh-calf contact parameters for six high knee flexion postures: Onset, maximum angle, total force, contact area, and center of force.
(Elsevier, 2018-01-23)In high knee flexion, contact between the posterior thigh and calf is expected to decrease forces on tibiofemoral contact surfaces, therefore, thigh-calf contact needs to be thoroughly characterized to model its effect. ... -
Three-dimensional comparison of static and dynamic scapular motion tracking techniques
(Elsevier, 2014-02)The shoulder is complex and comprised of many moving parts. Accurately measuring shoulder rhythm is difficult. To classify shoulder rhythm and identify pathological movement, static measures have been the preferred method. ... -
TIME VARYING GENDER AND PASSIVE TISSUE RESPONSES TO PROLONGED DRIVING
(University of Waterloo, 2008-08-15)Background: Prolonged sitting in an automobile seat may alter the passive tissue stiffness of the lumbar spine differentially in males and females. Gender specific ergonomic interventions may be indicated for the ... -
