The relationships of prolonged standing induced low back pain development with lumbopelvic posture and movement patterns
(University of Waterloo, 2014-11-10)Over 80% of individuals will suffer from low back pain at least once in their lifetime. The cause within the population is not homogenous, leading to sub-classifications of non-specific low back pain. One such sub-classification ... -
Representing fine-wire EMG with surface EMG in three thigh muscles during high knee flexion movements
(Elsevier, 2018-12-01)Activation waveforms of vastus intermedius, adductor magnus, and semimembranosus have not been reported for high knee flexion activities such as kneeling or squatting, likely due to the invasive procedures required for ... -
Resolving the influence of work sequencing which includes overhead work: implications for job cycle designs
(University of Waterloo, 2013-01-25)Many industrial workplaces involve tasks that require work to be performed in overhead postures. Epidemiological evidence suggests that working in these unavoidable, awkward postures leads to development of shoulder fatigue, ... -
Risk Assessment and Interventions for Individuals at Risk of Osteoporotic Fractures
(University of Waterloo, 2022-08-30)Older adults, especially with low bone mass, hyperkyphosis or vertebral fractures (OVF), and individual with spinal cord injury (SCI) are at increased risk of fragility fractures. Individuals with SCI and OVFs are subgroups ... -
Risk Factors for Falls in Home Care and Long-Term Care Settings: A Focus on Dementia and Parkinson's Disease
(University of Waterloo, 2013-06-21)It is well established that there are many intrinsic and extrinsic risk factors associated with falls in older adults. Less well-known is what risk factors predict falls in more vulnerable populations, such as those with ... -
The Role of Activities of Daily Living in Healthy Vascular Aging
(University of Waterloo, 2022-01-05)Normal aging leads to endothelial dysfunction and arterial stiffening implicated in cognitive decline. Cerebral blood flow also declines with aging. Elevated blood flow during exercise produces laminar shear stress which ... -
The Role of Acute High-Intensity Interval Exercise as a Potential Facilitator for Improved Executive Functions and Affect in Healthy Young and Older Adults
(University of Waterloo, 2021-01-06)A single bout of aerobic exercise has been shown to improve executive functions and affect across the lifespan. The magnitude of improvements appear to be influenced by exercise-dependent factors, including the intensity ... -
The Role of Apoptosis Repressor with Caspase Recruitment Domain in Aging Mouse Skeletal Muscle Morphology and Apoptotic Signaling
(University of Waterloo, 2015-01-23)Abstract Aging is associated with a loss of skeletal muscle mass, known as sarcopenia, which results in numerous degenerative alterations and decreased strength. One of the major mechanisms influencing muscle wasting in ... -
The Role of Binocular Vision during the Performance of Complex Manipulation Skills
(University of Waterloo, 2015-09-14)The overall goal for this thesis was to examine the significance of binocular vision during the performance of complex manipulation tasks in visually-normal children and adults. The goal of study 1 was to examine the ... -
THE ROLE OF CYTOSOLIC CALCIUM IN POTENTIATION OF MOUSE LUMBRICAL MUSCLE
(University of Waterloo, 2014-04-09)Following contractile activity, fast twitch skeletal muscle exhibits increases in submaximal force known as potentiation. Although there is no consensus on the purpose of potentiation, it is known to enhance power during ... -
The role of glutathione depletion in skeletal muscle apoptotic signalling in young and old rats
(University of Waterloo, 2010-09-27)There is substantial evidence that oxidative stress causes negative outcomes in many cell and tissue types. This is especially true of skeletal muscle, as it is continually subjected to various sources of reactive oxygen ... -
The Role of Heat Shock Protein 70 in Protecting Muscle Mechanical Function & SERCA Function in Human Skeletal Muscle
(University of Waterloo, 2009-04-23)Two studies were conducted to determine if Hsp70 is able to protect human skeletal muscle from muscle mechanical damage and alterations in SERCA activity associated with prolonged concentric exercise. In the first study, ... -
The role of phospholamban (PLN) in potential protection of sarc(endo)plasmic reticulum Ca2+-ATPase (SERCA) against oxidative stress
(University of Waterloo, 2015-01-23)Sarco(endo)plasmic reticulum Ca2+ ATPase (SERCA) sequesters Ca2+ from the cytosol to: i) aid in muscular relaxation and ii) refill SR Ca2+ stores for release upon subsequent stimulus for contraction. SERCA function is ... -
The Role of Phospholamban and Sarcolipin in Skeletal Muscle Disease
(University of Waterloo, 2016-01-19)Sarcolipin (SLN) and phospholamban (PLN) are two small proteins that physically interact with and inhibit the sarco(endo)plasmic reticulum Ca2+-ATPase (SERCA) pump. Results from our laboratory and others have shown that, ... -
The Role of Sarcolipin in Calcium Handling and Obesity
(University of Waterloo, 2010-05-19)Sarcolipin (SLN), a small molecular weight, hydrophobic protein found in skeletal muscle, is a known regulator of sarco(endo)plasmic reticulum Ca2+ ATPase (SERCA) pumps. Earlier in vitro reconstitution experiments have ... -
The Role of Sarcolipin in Muscle Adaptation with Aging
(University of Waterloo, 2024-04-08)The sarco(endo)plasmic reticulum Ca2+-ATPase (SERCA) pump facilitates the transport of Ca2+ against a concentration gradient from the cytosol to the lumen of the SR, eliciting relaxation and maintaining Ca2+ homeostasis. ... -
