Accuracy of self-reported intake of signature foods in a school meal intervention study: comparison between control and intervention period
(Cambridge University Press, 2015-08-28)Bias in self-reported dietary intake is important when evaluating the effect of dietary interventions, particularly for intervention foods. However, few have investigated this in children, and none have investigated the ... -
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 effects of aerobic exercise on cognitive function in individuals with Parkinson’s disease
(Elsevier, 2018-04-03)Deficits in executive functions are highly prevalent in Parkinson’s disease (PD). Although chronic physical exercise has been shown to improve executive functions in PD, evidence of acute exercise effects is limited. This ... -
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 ... -
Acute Regulation of Vascular Tone by AMP-activated Protein Kinase in Arteries of Healthy, Hypertensive and Aged Rats
(University of Waterloo, 2011-12-21)Background, Rationale and General Purpose: Several seminal observations suggest that AMPK mediates vascular tone: 1) in endothelial cell culture and in vitro isolated protein experiments, activation of AMPK stimulates ... -
Age-related changes in the control of mediolateral dynamic stability during volitional and reactive stepping
(University of Waterloo, 2012-04-23)The high incidence of falls and fall-related injuries among Canadians over the age of 65 continues to be a key public health issue. As the current proportion of individuals within this cohort of the population is predicted ... -
The aging spine: The effect of cyclic loading, simulated degeneration and prolonged sitting on joint stiffness across age
(University of Waterloo, 2018-08-22)Background: Low back pain is estimated to have a lifetime prevalence as high as 84%, and both the severity and frequency of low back pain reporting have a dependency on age. The nucleus pulposus and annulus fibrosis of ... -
Agpat4/Lpaat delta deficiency highlights the molecular heterogeneity of epididymal and perirenal white adipose depots
(American Society for Biochemistry and Molecular Biology, 2017-10-01)Acylglycerophosphate acyltransferase 4 (AGPAT4)/lysophosphatidic acid acyltransferase delta catalyzes the formation of phosphatidic acid (PA), a precursor of triacylglycerol (TAG). We investigated the effect of Agpat4 gene ... -
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 ... -
Analysis of Transcranial Doppler Ultrasound Waveform Morphology for the Assessment of Cerebrovascular Hemodynamics
(University of Waterloo, 2012-08-29)The use of transcranial Doppler (TCD) ultrasound for the assessment of cerebral blood flow velocity (CBFV) provides an indication of cerebral blood flow assuming the diameter of the insonated vessel remains constant. Studies ... -
Anticipatory planning in object manipulation: A cross-sectional investigation of children, young adults and older adults
(University of Waterloo, 2016-08-25)Over a series of five studies, this work aimed to investigate anticipatory planning in object manipulation across the human lifespan. Main objectives were to: (a) understand the influence of the movement context; (b) ... -
Aperture Crossing in Challenging Environments: An Examination of the Factors that Influence the Passability of Narrow Spaces
(University of Waterloo, 2016-04-13)In order to get to where we need to go, locomotion often involves walking through narrow spaces. Whether an aperture affords passage is thought to be determined by the body size/aperture size relationship. For normal, ... -
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 ... -
Arm posture influences on regional supraspinatus and infraspinatus activation in isometric arm elevation efforts
(Elsevier, 2019-02)This study aimed to evaluate the effect of arm posture on activation of the anterior and posterior regions of supraspinatus and the superior and middle regions of infraspinatus during resisted isometric arm elevations. ... -
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 ... -
