Resistance Training And Running Performance And Economy: A Literature Review, James Bottrill 2023 Portland State University

Resistance Training And Running Performance And Economy: A Literature Review, James Bottrill

University Honors Theses

Running performance is largely determined by maximal oxygen uptake (VO2 max), velocity at VO2 max, fractional utilisation of VO2 max and running economy. Running economy is relatively under-researched and could be improved by resistance training because of its neuromuscular underpinnings. However, existing research on this topic is quite unorganised and inconclusive and is yet to prove a direct linkage between resistance training, running economy and performance. This literature review aimed to provide an organised overview of the existing literature, identify and address confounding variables and provide recommendations for future research. A search for studies was conducted via …

External Workloads Vary By Position And Game Result In Us-Based Professional Soccer Players, Gary M. Long, Sam M. Joyce, Robert T. Herrington, Kyle B. Fox, Jack E. Mumaugh

International Journal of Exercise Science

International Journal of Exercise Science 16(6): 688-699, 2023. Professional soccer is a physically demanding sport that requires players to be highly trained. Advances using GPS allow the tracking of external workloads for individual players in practice and competition, however, there is a lack of evidence on how these measures impact match results. Therefore, we analyzed external workloads by player position and determined if they vary depending on the result of competitive matches. External workloads were analyzed in professional soccer players (n = 25) across 28 competitive games. One-way ANOVA determined if workloads varied by position (striker – ST, wide …

International Journal of Exercise Science

International Journal of Exercise Science 16(2): 700-709, 2023. Reduced cardiac baroreflex sensitivity (cBRS) is an autonomic marker associated with a worse cardiovascular prognosis. Whether cBRS is lowered in people living with HIV (PLHIV) is yet unclear, as well as potential moderator effects of body mass index (BMI) or physical activity (PA) level. The present study aims to compare the spontaneous cBRS in PLHIV vs. HIV-uninfected controls, and to determine among PLHIV the relationship between cBRS vs. body mass index (BMI) and PA level. Total, upward (cBRS+), and downward (cBRS-) cBRS gains were assessed using the sequential method from beat-to-beat …


Unearthing Complexity: Tangible Histories Of Water And Earth, Alexis Violet 2023 Rhode Island School of Design

Unearthing Complexity: Tangible Histories Of Water And Earth, Alexis Violet

Masters Theses

Unearthing Complexity investigates conceptions of time and surface through geological stories of the water and earth. Building on theories of deep time, hydrofeminism, critical zones, and grounding, I hope to foster a deeper awareness of time scales other than our own and a more tangible understanding of the embodied experience of matter in the universe. Working toward a new literacy of the water and earth in which they are recognized as living, changing bodies to which we are inherently tied at a molecular level, the site of this multiscalar inquiry occurs in the coastal zones of the Narragansett Bay where …

Cancer can develop in almost any part of the body since cancer is defined as uncontrolled cell growth. The FLASH Effect is seen when treating …


Gpr75 Deficiency Attenuates High Fat Diet-Driven Obesity And Glucose Intolerance, Sakib Hossain 2023 NYMC

Gpr75 Deficiency Attenuates High Fat Diet-Driven Obesity And Glucose Intolerance, Sakib Hossain

NYMC Student Theses and Dissertations

Recently, a collaboration between Regeneron Pharmaceuticals and the Schwartzman-Garcia labs at New York Medical College published an exome sequencing study of individuals across the United Kingdom, United States, and Mexico which concluded that individuals possessing non-functioning, truncated mutations to the orphan g protein coupled receptor (GPCR), GPR75, had lower BMI and 54% reduced likelihood of obesity. The present study was undertaken to fully characterize the metabolic phenotype of Gpr75 deficient mice when fed a high fat diet (HFD) and explore potential mechanisms by which GPR75 activation links to increased adiposity and decreased glucose tolerance. After 14 weeks of HFD-feeding we …


Does Caffeine Consumption Affect Work Performance Across Different Job Types?, Bryan JS Goh, Joshua Tan, Cleavon Chong, Sean Ker 2023 Embry-Riddle Aeronautical University

Does Caffeine Consumption Affect Work Performance Across Different Job Types?, Bryan Js Goh, Joshua Tan, Cleavon Chong, Sean Ker

Introduction to Research Methods RSCH 202

We propose executing a panel series case study for a large organization in Singapore over a year to examine how caffeine impacts work performance across different job types. Our research question is how does caffeine affect work performance under different conditions due to work type differences. Our dependent variable would be work performance as measured by employees’ Key Performance Indicators (KPIs). We propose to gather data for two of our important independent variables: caffeine use through a recorded pantry system and average sleep hours from a survey. We will analyze the data by using two-factor ANOVA with replication to find …

Social Creatures: The Impact Of Solitary Confinement On Psychophysiological Health And How Inmates Percieve Their Humanity And Social Well-Being, Julia Austin

Honors Projects

This paper will define and examine the use of solitary confinement within the United States prison system and review its mental, physical, and social impacts. As social creatures, human mental and physical well-being depends on meaningful social interactions absent in segregation units. As it currently stands, vulnerable populations, including racial minorities, LGBTQIA+ individuals, and those with developmental disabilities or psychological disorders, are at risk of irrevocable harm and abuse within these facilities from staff as well as other inmates. With a rotating 80,000 inmates held in solitary confinement every day, the current structure of the prison system deemphasizes rehabilitation and …

Eco-Interoception: What Plants, Fungi And Protista Have Taught My Body, Sara Riley Dotterer 2023 Southern Methodist University

Eco-Interoception: What Plants, Fungi And Protista Have Taught My Body, Sara Riley Dotterer

Art Theses and Dissertations

To me, ecology is the relational, full-body awareness that I am made up of and deeply connected to everything around me; and for better or worse, this is reciprocal. I form ecotones, an ecological transitional zone between two ecosystems, with the world around me. I use this ecotonal lens to blur binaries and dissolve boundaries between me and the world “outside my body.” During my Masters of Fine Arts at Southern Methodist University, I have continuously explored and represented the lives of various more-than-human species outside of my body, including plants, fungi and protista through an ecotonal lens. Although these …


An Argument For The Utilization Of Amphibian Stress As An Indicator Of Wetland Condition, Andrew W. Sisson 2023 Murray State University

An Argument For The Utilization Of Amphibian Stress As An Indicator Of Wetland Condition, Andrew W. Sisson

Honors College Theses

Traditional forms of rapid wetland condition assessments focus on foliage health, nutrient enrichment, chemical contamination, and surrounding land usage, often overlooking an evaluation of the animals living in the wetland. More intense assessments include the National Wetland Condition Assessment (NWCA) and indices of biotic integrity, which focus on community composition (e.g., diversity and species richness) and abundances. These indices require expertise in species identification and do not provide information about the animal’s fitness. Animal stress physiology, which generally correlates with measures used to quantify animal fitness (e.g., survival, reproduction, and body condition), may provide a complementary rapid assessment method aimed …

Multichannel Modulation Of Depolarizing And Repolarizing Ion Currents Increases The Positive Rate-Dependent Action Potential Prolongation, Candido Cabo 2023 CUNY New York City College of Technology

Multichannel Modulation Of Depolarizing And Repolarizing Ion Currents Increases The Positive Rate-Dependent Action Potential Prolongation, Candido Cabo

Publications and Research

Prolongation of the action potential duration (APD) could prevent reentrant arrhythmias if prolongation occurs at the fast excitation rates of tachycardia with minimal prolongation at slow excitation rates (i.e., if prolongation is positive rate-dependent). APD prolongation by current anti-arrhythmic agents is either reverse (larger APD prolongation at slow rates than at fast rates) or neutral (similar APD prolongation at slow and fast rates), which may not result in an effective anti-arrhythmic action. In this report we show that, in computer models of the human ventricular action potential, the combined modulation of both depolarizing and repolarizing ion currents results in a …

Heart Rate Response And Locomotor Activity Of Female Skateboarders, Bipoc Skateboarders, And Non-Skateboard Users During A Typical Session At A Community Skatepark, Jeff A. Nessler, Alivia L. Lundquist, Natalie Casas Jimenez, Sean C. Newcomer

International Journal of Exercise Science

International Journal of Exercise Science 16(7): 599-612, 2023. Prior research has demonstrated that male adults and youth engaged in skateboarding at community skateparks achieve heart rates that meet or exceed recommendations for exercise by the CDC. However, these studies do not adequately evaluate other non-traditional or ethnically diverse users who may differ in how they utilize the skatepark and in their cardiovascular response. The purpose of this experiment was to measure heart rate response and locomotor movement in three lesser studied groups that frequently utilize community skateparks, and to compare these results with those reported previously in male adult and …
