Understanding Components Of Motor Imagery Ability And The Association With Motor Proficiency In Children And Young Adults, Chadwick Tyler Fuchs

Kinesiology Dissertations - Archive

Motor imagery (MI) refers to the imagination of a motor task without actual movement execution (Decety & Grézes, 2006) and is believed to represent one’s ability to accurately utilize forward internal models of motor control (Williams et al., 2006). Moreover, MI seems to rely on a network involving motor related regions including fronto-parietal areas and subcortical structures, supporting the view that MI and motor execution are very similar processes (Hétu et al., 2013). This ability has been shown to emerge between 5 and 7 years of age and improve during childhood and adolescence (Molina, Tijus, & Jouen, 2008; Spruijt, van …

Novel Mechanisms Of Peripheral Vascular Dysfunction In Patients With Type 2 Diabetes, Ben Earl Young

Kinesiology Dissertations - Archive

Currently, over 30 million adults in the United States have been diagnosed with Type 2 Diabetes mellitus (T2D). Importantly, T2D disproportionately augments the risk for the development of cardiovascular disease (CVD), which is currently the leading cause of morbidity and mortality in the United States. A hallmark characteristic of T2D is insulin resistance (IR), defined as a reduced tissue responsiveness to insulin stimulation, which contributes to prolonged periods of post-prandial hyperglycemia and is associated with a compensatory rise in pancreatic insulin secretion (hyperinsulinemia). Importantly, there is a well-known bi-directional association between the degree of IR/hyperinsulinemia and hypertension (HTN), with nearly …

Dysregulated Calcium Signaling In Cardiomyocytes From Diabetic Atrial Fibrillation To Chemotherapy-Induced Cardiac Hypertrophy, Xian Liu

Kinesiology Dissertations - Archive

Ca2+ is a vital second messenger in cardiomyocytes and controls excitation-contraction coupling. It also regulates cell cycle, apoptosis, hypertrophy and downstream gene transcription in the heart remodeling. Calcium homeostasis is a complicated network and the intracellular Ca2+ signaling is composed of different Ca2+ movements like Ca2+ spikes [1], waves and oscillations [2-4]. The spatially-temporally regulated Ca2+ signaling is orchestrated with the Ca2+ release through ryanodine receptor (RyR) or IP3 receptor (IP3R) from Ca2+ stores such as sarcoplasmic/endoplasmic reticulum (SR/ER), recycling of Ca2+ from cell plasma back to the ER and Ca2+ influx through plasma membrane (PM) from extracellular space. There …

Folk Physics In The Twenty-First Century: Understanding Tooling As Embodied, Dorothy M. Fragaszy, Madhur Mangalam

Journal Articles

Povinelli’s (2000) studies with chimpanzees (Pan troglodytes) reported in “Folk Physics for Apes” were firmly grounded in a Cartesian view of knowledge, which posits that humans use abstract concepts such as force, gravity, and shape to reason causally about events and plan our actions (with tools in the case of Folk Physics for Apes). Povinelli set out to examine if chimpanzees, like humans, used causal concepts to solve mechanical problems, as the Cartesian view predicts. However, Povinelli’s findings uniformly challenged his expectations. Povinelli’s book stimulated research and contributed to the development of alternate understandings of how animals (including humans) use …

The Influence Of Cerebellar Transcranial Direct Current Stimulation On Motor Function In Parkinson’S Disease, Lidio Lima De Albuquerque

UNLV Theses, Dissertations, Professional Papers, and Capstones

Parkinson's disease (PD) is the most common movement disorder and the second most common neurodegenerative disorder. PD is characterized by dopaminergic cell loss in the substantia nigra pars compacta, which leads to a reduction in dopamine in the striatum. These physiological mechanisms lead to a number of motor impairments such as bradykinesia, rigidity, tremor, and postural instability that severely limit the ability of individuals with PD to perform many essential daily living activities. Although current pharmacological, surgical, and physical exercise treatment approaches are valuable they are either only mildly effective, expensive, or associated with a variety of side effects. Therefore, …

Effects Of Intermittent Fasting And Physical Activity On Salivary Expression Of Reduced Glutathione And Interleukin-1b, Colton Allen, Brandon Sellers, Mackinzie Smith, Alyssa Edwards, Kirsten Gateless, Bailey Aab, Kalee Sherrard, Carl Bolyard, Shawn Stover

International Journal of Exercise Science

International Journal of Exercise Science 13(7): 1063-1071, 2020. Previous research has consistently demonstrated that regular exercise promotes antioxidant production and decreases the expression of inflammation markers. However, there is very little research examining the effects of intermittent fasting (IF) on oxidative stress and inflammation. The present study investigated the hypothesis that a combination of IF and physical activity will reduce the need for glutathione (GSH) production by decreasing oxidative stress. In addition, it was hypothesized that a combination of IF and physical activity will significantly reduce inflammation, as indicated by a decrease in interleukin-1b (IL-1b) concentration. For three months, subjects …

Black Drowning Deaths: An Introductory Analysis, Alena Gadberry, James Gadberry

International Journal of Aquatic Research and Education

Black children between the ages of 5 and 14 are 2.6 times more likely to drown than white children. A systematic exclusion from public pools and other forms of water activities over time has led to a lack of cultural capital involving aquatics among black families. Pierre Bourdieu has provided a theoretical foundation in which to understand this issue. The social fields created by generational socialization have made blacks feel like they have no place in the water. It will take a restructuring of the social institutions to set in motion the socialization (or a re-socialization) of new and more …
