Prevalence Of Mental Health Issues In Division Iii Athletes, Logan Streety

Honors Theses

College athletes have always struggled with their mental health, and it has recently become more widely recognized because of their lifestyle. Between managing schoolwork, team responsibilities, and having a social life, it is extremely easy to become overwhelmed and put other things before one’s psychological health. In this study, the SUNY Cortland Women’s Basketball team was surveyed to determine if depression, anxiety, and stress are prevalent in athletes at SUNY Cortland. The DASS-21 questionnaire was distributed to each of the women’s basketball athletes. This 21-question survey produced scores that determined whether they are experiencing symptoms of depression, anxiety, and/or stress. …

The Influence Of Music Tempo On Bench Press Power Production In College-Aged Males, Samuel Linderbaum, Reese Pantila

Applied Health Sciences Student Works

Previous research suggests that music with a tempo exceeding resting heart rate may stimulate the sympathetic nervous system (SNS), releasing catecholamines (epinephrine and norepinephrine). These hormones have physiological effects such as increased heart rate and muscle strength in cardiovascular exercise. This study aims to see if the effect of music in cardiovascular exercise is also present in strength training. This will be done by examining whether pre- and intra-exercise music listening at different tempos affects power output during bench press repetitions in young adult males. It is hypothesized that music at a higher tempo will stimulate the SNS and result …

Acl Bracing: Is It Still Being Done Clinically And Does It Influence Confidence And/Or Biomechanical Performance During A Drop Vertical Jump?, Bailey Watson

Masters Theses & Specialist Projects

Introduction: Anterior cruciate ligament (ACL) ruptures account for 60% of sports-related injuries and the gold standard for treatment is surgical intervention to replace the damaged ligament to restore function of the ACL. Braces are typically used to return to previous physical activity levels; however, there are no clear guidelines on their utilization. Beyond the physical consequences of undergoing ACL reconstruction surgery, the psychological component is often ignored.

Purpose: The aim of this study is to better understand the impact of knee bracing on both biomechanical factors and confidence following ACL reconstruction. Two aims comprise the overarching purpose; the first is …

Evaluating The Effect Of Garden-Based Education On Young Learners’ Preferences For And Willingness To Try Healthy Food, Sierra Gregory

Agricultural Economics and Agribusiness Undergraduate Honors Theses

Childhood obesity in American children has tripled in the last 20 years, and 85% of current healthcare spending is linked to diet-related diseases. The consumption of highly processed foods is linked to these trends and makes up more than half of an average American youths’ diet. Reducing the consumption of highly processed foods in children’s diets can be addressed, in part, by addressing childhood neophobia (willingness to try new foods) associated with whole foods like fruits and vegetables. Influence over behavioral areas such as nutrition and in early childhood is essential to long-term sustained health, and garden-based interventions shows promise …

Cannabidiol (Cbd) And Resistance Training: Does Cbd Attenuate Acute Pain?, Guillermo Pacheco

Masters Theses & Specialist Projects

INTRODUCTION: Resistance training (RT) is an advantageous form of physical activity for health and performance benefits; these benefits are maximized when done strenuously. However, strenuous RT can induce acute inflammatory pain which can lead to delayed-onset muscle soreness (DOMS). Common analgesics like non-steroidal anti-inflammatory drugs (NSAIDs) can block protein synthesis, so other alternatives are needed for exercise and athletic communities to maintain physiological adaptations. Cannabidiol (CBD) is a non-psychotropic cannabinoid with purported anti-inflammatory, anti-oxidative, and analgesic properties. One of the main reasons for the use of CBD in exercise is pain alleviation; however, research in humans is limited. Therefore, the …

Phenotypic Plasticity In Pigmentation: Investigating Coloration Patterns In Anablepsoides Hartii Population Responses To Environmental Variation, Jasdeep Kaur

2024 Spring Honors Capstone Projects - Archive

In this study, we investigated the color-changing capabilities of Trinidadian killifish, Anablepsoides hartii, through exposure to varied color conditions over defined periods of time. Our experiment aims to understand adaptive responses when killifish are subjected to different color backgrounds, exploring their mechanisms to change color. By subjecting the species to different environmental color variations, we sought to discern color change patterns, which could indicate adaptive responses related to camouflage, stress, behavior clues, and physiological adjustments. Carefully controlling environmental factors, we monitored and documented the fishes’ color changes, aiming to provide insights into the interplay between fish’s developmental plasticity and its …

Evaluating The Epidemiological, Hormonal, And Psychosocial Sex-Based Differences In Sports-Related Concussion Outcomes, Samantha Kanny

All Dissertations

Sports-related concussions (SRCs) affect approximately 3.8 million athletes in the United States per year. A multitude of risk factors including age, sex, concussion history and prior medical conditions have been observed to significantly increase sports-related concussion symptom burden. Researchers have posited many reasons to explain sex-based differences in SRC outcomes, often categorized by biological characteristics or sociocultural factors, however, females are vastly underrepresented in sports-related concussion research, making it difficult to understand the true mechanisms underlying SRC sex-based differences. The goal of this dissertation is to help fill the current gap in knowledge on sex-based differences in sports-related concussion outcomes. …

The Role Of Oncomodulin In The Central Nervous System Inflammation, Evan Paltjon

Honors Theses

Acoustic overexposure in mice leads to an excess of calcium influx in outer hair cells (OHCs) and causes permanent hearing loss due to death of OHCs. Oncomodulin is a parvalbumin calcium buffering protein located in OHCs of the cochlea. Early pilot studies indicate that genetic deletion of OCM results in immune-related pathology throughout the cochlea. Why and how this occurs is unknown. Studies in wild type (WT) and OCM knockout (KO) mice demonstrate greater numbers of immune cells are associated with noise exposure in an OCM knockout than in WT. Expression of toll-like receptor 4 (TLR4) leads to the recruitment …

Effects Of Maternal Infant-Directed Sensory Cues On Early Weaned Piglet Behavior, Mattie Still

Animal Science Undergraduate Honors Theses

In the commercial pig production industry, weaning is a stressful time. Stress is related to loss in production due to increased incidence of illness, increased aggression, and reduced rate of gain, which results in economic losses for the producer. The purpose of this continuous behavior study was to explore the effects of provisional own-mother olfactory and auditory stimuli on early weaned piglet behavior and growth. During days 7-14 postpartum, the grunting of 12 individual sows was recorded while their piglets nursed. The audio files were put into a single loop with grunting occurring for 20 minutes followed by 60 minutes …

Transcranial Magnetic Stimulation And The Rtpj (Right Teaching Parietal Junction), Molly Skowron

Theses, Dissertations and Culminating Projects

Theory of Mind (ToM) is conceptualized as the ability to infer the thoughts and feelings of others. Many studies have found that ToM abilities play a central role in collaborative communication between adults, and that teachers are more effective when they have high levels of ToM. One of the main brain regions implicated in ToM is the right temporoparietal junction (rTPJ), which is thought to be responsible for evaluating a person’s belief formation process. The current study had participants engage in a Lego model building task consisting of a director who instructed a builder on how to create duplicate models …

Maternal Experience-Driven Changes In Oxytocin Neuron Co-Localization With Crf Receptors In The Hypothalamus Of Mice, Katherine Parra

Legacy Theses & Dissertations (2009 - 2024)

The postpartum period is a time of adaptiveness for new mothers who have to not only maintain their own health and well-being, but also that of a brand-new life. In both humans and across various common laboratory species like rats, mice, and non-human primates, priorities must shift greatly for a new mother to now include initiation and maintenance of offspring-focused behaviors regardless of her circumstances.The neurobiology of this adaptivity includes a complex sequence of changes that amount to suppression of hypothalamic-pituitary-adrenal (HPA) axis activity. Corticotropin-releasing factor receptor 1 (CRFR1) is a receptor involved with initiating the physiological stress response and …

Methods: Healthy young adults (n = 9) completed 3 experimental trials consisting of 4-hour sedentary periods. The trials consisted of an uninterrupted sedentary period (control), treadmill walking every 30 minutes for 5 minutes, and bodyweight-based muscular strengthening exercises every 30 minutes for 5 minutes. Blood glucose was measured at baseline and every 30 minutes thereafter. Blood pressure and fatigue were measured at baseline and every hour thereafter. …

The Impact Of One Night Of Sleep Restriction On Perception Of Subsequent Aerobic Exercise Performance, Erin G. Meier

Senior Honors Projects, 2020-current

Introduction: Previous research has established that poor sleep quality negatively impacts aerobic exercise performance. A majority of that research has examined extreme sleep disruption like complete sleep deprivation or multiple nights of reduced sleep. Little research exists examining the effect of a singular night of sleep restriction (SR) on performance, and there is even less research on the associated perceptual feelings and outcomes from SR that may influence performance. Previous research from our laboratory has suggested that a single night of SR may impair performance, but did not account for sleep inertia or examine any perceptual factors. Therefore, the …

It is predicted that 68% of people will live in cities by 2050. The City of Greenville is a rapidly growing city in South Carolina that has been losing its tree canopy to development(City of Greenville, 2023). The Urban Tree Canopy (UTC) is a community asset that provides many quality-of-life benefits including improved air quality, stormwater management, carbon sequestration, mental and physical well-being, increased mobility and access, aesthetics, a reduction in energy costs, …

The Anti-Diabetic Drug Metformin Disrupts Feeding And Sleeping Behaviors In Drosophila Melanogaster., Lucas Fitzgerald

College of Arts & Sciences Senior Theses

Dimethylbiguanide, also known as metformin, is the single most prescribed oral treatment for non-insulin dependent diabetes mellitus, or type 2 diabetes, in Western countries. The primary mechanism of action that metformin acts through is the activation of AMP kinase, an important regulator of energy homeostasis. While the anti-diabetic effects of metformin are well documented, its effects on feeding and sleeping behaviors are not well characterized. Using the model organism Drosophila melanogaster, the mean daily quantity of food consumed was measured and compared between groups treated with several dosages of metformin. Feeding interactions such as meal frequency and length were …

The Influence Of Researcher Disturbance On Raccoon Predation Of American Alligator Nests, Clarissa Tuten

Electronic Theses and Dissertations

Raccoons (Procyon lotor) are a dominant predator of American alligator (Alligator mississippiensis) nests in the southeastern United States, using a combination of olfactory, visual, and tactile cues to identify nest locations. Studies on alligator nesting ecology typically require researchers to create paths through marsh habitat, potentially introducing visual and olfactory cues raccoons may use to locate nests. The purpose of this study was to evaluate the effect of human visitation to alligator nests on the frequency of raccoon nest predation at two sites in coastal South Carolina, Tom Yawkey Wildlife Center (TYWC) and Santee Coastal Reserve (SCR). We hypothesized that …

Stories Of Motivation And Values Of Small-Scale Farmers In Jamaica And The United States, Raquel Taylor

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Small-scale farmers add to global and local food systems through various means such as connecting communities to local food and support economies. Small-scale farms can address issues related to food and nutritional security. However, farming can be a challenging career to engage in, especially for those who are small-scale farmers. Matters related to succession, higher paying off-farm employment, policies, and more can make it challenging to engage in farming. Leaving the question of what would motivate someone to engage in small-scale farming. Motivation can be viewed through multiple lenses; this study chose to use self-determination theory to understand the motivations …

Vibratory Noise Impacts The Sensory Ecology Of A Funnel-Weaving Spider, Brandi June Pessman

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Animals experience their world through diverse sensory systems, leveraging information from prey, predators, and potential mates to inform behavioral decisions. Environmental noise disrupts information via spectral or amplitude masking, degradation, or distortion, potentially leading to costly errors in responses. Critically, urbanization has accelerated the proliferation of novel noise sources, triggering significant shifts in communication, foraging, and predator-prey dynamics among urban wildlife. While vertebrate studies have illuminated urban animals’ flexibility to anthropogenic acoustic noise, a comprehensive understanding requires broader investigations across diverse animal taxa and sensory modalities. To address these gaps, my dissertation explored the impacts of anthropogenic substrate-borne (vibratory) noise …

Mate Guarding Against Strong Men Displaying Affiliative And Aggressive Humor, Jacob Pauley

Biological Sciences Undergraduate Honors Theses

Mate retention behaviors serve to discourage partner defection from a current pairbond. Such behaviors are oftentimes more prevalent toward intrasexual rivals exhibiting physical and behavioral cues implicating that rival as an optimal mate. Among these features in men are their upper body strength, a feature diagnostic of heritable fitness, and men's ability to produce humor, a cue to their social competence. This study considered the intersection of these desirable features in shaping men's mate retention behavior toward an intrasexual rival. After learning of a hypothetical interloper exhibiting high or low upper body strength while similarly using humor in an affiliative …

Effect Of Progesterone On Cognition Among College Aged Women, Katelyn Helberg

Biological Sciences Undergraduate Honors Theses

Women who have a reoccurring menstrual cycle and do not take hormonal birth control naturally experience changes in the amount of sex hormones that their body produces. These sex hormones help promote sexual development, fertility, and mood regulation, but can be hard to study due to their conflicting effects on each other. One such hormone, progesterone, is produced in different concentrations throughout the menstrual cycle to prepare the uterus for a potential pregnancy. However, it also may have secondhand effects on how well women can complete everyday tasks involving memory, attention, processing speed, and more which is what we measured …

The Effect Of Hormonal Contraceptive Use On Dominance And Prestige Tactics, Carson Chappell

Biological Sciences Undergraduate Honors Theses

This study was designed to investigate the relationship between hormonal contraceptives and prestige and dominance status-seeking tactics. Existing literature has examined how the hormones estrogen and progesterone, especially in relation to the fertile window of the menstrual cycle, are associated with prestige and dominance but has yet to look in depth at how hormonal contraceptives might alter this impact. The current study asked participants to complete a 22- item questionnaire assessing dominance and prestige. I hypothesized that women on hormonal contraceptives would have lower scores for prestige and dominance compared to women who are naturally cycling. The results did not …

A Comparison Of Spinal Reflex Function And Morphological Adaptations Of The Achilles Tendon Between Individuals Chronically Post-Stroke And Healthy Controls, Migi Contreras, Mira Seekins, Johanna Mendez, Trevor Diez

UNLV Theses, Dissertations, Professional Papers, and Capstones

Purpose/Hypothesis: The hallmark gait deviation in individuals with post-stroke hemiparesis is slow walking speed. Reduction in gait speed after stroke is influenced by decreased propulsive forces, which may likely be related to impaired spinal circuit function and spasticity of the paretic plantarflexors. Chronic muscle tone maladaptations in paretic ankle plantarflexors can result in altered Achilles tendon (AT) morphology, therefore leading to altered mechanical properties, force transmission capabilities and subsequent insufficient propulsive forces during walking. The purpose of this study is to characterize the chronic maladaptations in both the spinal Ia afferent loop excitability and AT morphology after stroke lesions in …
