Cortisol Production In Female Soccer Players, Katelyn Seagraves

ASPIRE 2024

Cortisol is released from the adrenal glands when there is an apparent stressor. Exercise, while beneficial, is seen as stress to the body and incites increased cortisol release. Cortisol is known to increase with exercise, and higher-intensity exercise tends to raise cortisol more compared to lower intensities. However, less is known about interval training and cortisol concentrations.

This review of literature dives into the background of cortisol: how it's produced, what systems it regulates, and differences in production based on gender, stressors, exercise intensity, and duration. This paper identifies some knowledge gaps and links training intensities in soccer to cortisol …

Metabolic Foundations Of Exercise-Induced Cardiac Growth., Kyle Fulghum

Electronic Theses and Dissertations

Regular aerobic exercise promotes physiological cardiac growth, which is an adaptive response thought to enable the heart to meet higher physical demands. Cardiac growth involves coordination of catabolic and anabolic activities to support ATP generation, macromolecule biosynthesis, and myocyte hypertrophy. Although previous studies suggest that exercise-induced reductions in cardiac glycolysis are critical for physiological myocyte hypertrophy, it remains unclear how exercise influences the many interlinked pathways of metabolism that support adaptive remodeling of the heart. In this thesis project, we tested the general hypothesis that aerobic exercise promotes physiological cardiac growth by coordinating myocardial metabolism to promote glucose-supported anabolic pathway …

From Young To Old: The Effects Of Sedentary-Aging And Exercise Interventions On Structural Plasticity Of Lumbar Motor Neurons, Nmj, And Glial Cell Line-Derived Neurotrophic Factor Expression, Alberto Felipe Cintron-Colon

Dissertations

Neuromuscular weakness has been associated with age progression. A possible reason is a disconnection between muscle and neuron, causing components from both the central and peripheral nervous systems to deteriorate. Exercise, however, has beneficial effects for both muscle and nervous tissue, inducing neuroprotection. Neurotrophic factors are powerful regulators of neuronal maintenance and synaptic strength. Glial cell line-derived neurotrophic factor (GDNF) is a neurotrophic factor that has been shown to be a potent survival factor for somatic motor neurons that innervate skeletal muscle.

This study aims to evaluate changes in structural plasticity of motor neurons in the lumbar spinal cord and …

Water Intoxication: Current Developments In Hyponatremia, Allison C. Mosmiller

Student Publications

This paper is a review of recent research on the subject of exercise-associated hyponatremia. Hyponatremia is notoriously difficult to diagnose and to treat due to its general symptoms and required specificity in diagnosis in order to assign appropriate treatment. If left untreated, Hyponatremia can result in the development of complications like cerebral edema, seizures, coma, and sometimes death. The pathogenesis of hyponatremia includes multiple proposed mechanisms, including overconsumption of hypotonic fluids, inappropriate release of antidiuretic hormone, inefficiency of fluid filtration by the kidneys, redirection of fluid into intestinal lumen, and activation of the renin-angiotensin-aldosterone system. Signs and symptoms of hyponatremia …

Effects Of A Demand-Valve Scuba Regulator On Cardiorespiratory Response During Submaximal Exercise Under Normobaric Conditions: A Preliminary Investigation, Christopher R. Kovacs Ph.D., Camille Dhom B.S.

International Journal of Aquatic Research and Education

SCUBA diving fatalities are often related to cardiac events triggered by stress linked to equipment. The purpose of this investigation was to examine the effects of a SCUBA regulator on cardiorespiratory exercise at a submaximal workload. Ten participants (mean = 21.5 yrs; s.d. = 1.16) completed two submaximal exercise tests at 1 ATA; one while breathing normally and a second while breathing directly from a demand valve SCUBA regulator. Total time to test completion (TOT), heart rate (HR), blood pressure (BP), rating of perceived exertion (RPE), and arterial oxygen levels were all assessed. No significant differences between conditions were found …

Examining The Effects Of Exercise-Induced, Physical Stress Overtraining On Stress Biomarkers In Adolescent, C57bl/6 Mice, Curtis Scotty Davis

Theses, Dissertations and Capstones

Exercise has long been established as a therapeutic modality to improve health and related physical fitness, sports performance, and injury/risk reduction in both adults and adolescents (Haff & Triplett, 2015; Kaminsky, 2010). Nonetheless, there is a lack of research investigating the negative effects of exercise overstress (i.e., overtraining syndrome) in these populations, particularly adolescents (Brenner & American Academy of Pediatrics Council on Sports Medicine and Fitness, 2007; Matos & Winsley, 2007). The objective of this study was to examine hormone biochemical markers, anthropometric markers, and behavioral traits, which are associated with overtraining syndrome, in adolescent C57BL/6 mice. A total of …

The Effect Of Sprint Interval Training And Intermittent Fasting On Cognitive Function, Dana Taghaddos

Undergraduate Student Research Internships Conference

This study will explore how a combination of a time-restricted eating (TRE) strategy and a sprint interval training (SIT) exercise program will affect cognitive function. Both TRE and SIT are easily implemented lifestyle habits that have been shown to present significant brain challenges. Participants will be randomized into 3 groups: either SIT + TRE (Group 1), SIT alone (Group 2), or TRE alone (Group 3). We will assess acute effects (single day of TRE, followed by a single session of SIT the next day), and the effects over a 6 week period. The SIT protocol consists of four 30 second …

Effect Of High Intensity Interval Training Vs Low Intensity Training On Fat Loss In Patients With Obesity, Jonathan Aaron Deck, Adarsh Gupta

Rowan-Virtua Research Day

Nowadays, there are several exercise modalities to lose weight, retain, and or build lean body mass. A widely known training philosophy that has gained increased popularity is high intensity interval training (HIIT). HIIT is based on exercising at submaximal or maximal intensity for a brief period then reducing work to minimal intensity for a longer duration in a series of repeated bouts. The benefit of HIIT is to increase fat loss through the scientific principle of EPOC (excess post exercise oxygen consumption). Low intensity training (LIT) also has its benefits in that it is more sustainable but with the caveat …

Commentary: Physiological And Psychological Impact Of Face Mask Usage During The Covid-19 Pandemic, Jennifer Scheid, Shannon Lupien, Gregory Scott Ford, Sarah West

Articles & Book Chapters

In this commentary, we discuss the physiological effects of wearing masks for prolonged periods of time, including special considerations, such as mask wearing among those who engage in exercise training, and concerns for individuals with pre-existing chronic diseases. In healthy populations, wearing a mask does not appear to cause any harmful physiological alterations, and the potentially life-saving benefits of wearing face masks seem to outweigh the documented discomforts (e.g. headaches). However, there continues to be controversy over mask wearing in the United States, even though wearing a mask appears to have only minor physiological drawbacks. While there are minimal physiological …

Zebrafish As A Model To Understand The Impact Of Inactivity And Neuromuscular Electrical Stimulation On Duchenne Muscular Dystrophy, Elisabeth Kilroy

Electronic Theses and Dissertations

Skeletal muscle plasticity is imperative for functional adaptation to changing demands in activity. Although a great deal is known about the structural and functional plasticity of healthy skeletal muscle, far less is known about plasticity in diseased muscle. Here, we combined the power of the zebrafish model with the adaptability of neuromuscular electrical stimulation (NMES) to study the basic mechanisms of plasticity in the zebrafish model of Duchenne Muscular Dystrophy (DMD). Four NMES paradigms, defined by their frequency, delay, and voltage, were designed to emulate the repetition and load schemes of human resistance training programs. Additionally, two inactivity paradigms were …

The Implementation Of Exercise For Chronic Kidney Disease And Dialysis Patients, Syed Ahmad Rizvi

Honors College Theses

While commonly known to be the organ that helps with urine production within the human body, the kidney plays one of the most crucial roles in maintaining homeostasis. When establishing all of the roles the kidney has on keeping humans healthy, there is the question of how does the body cope when a patient is diagnosed with kidney failure. One of the more common treatment options that allows the body to continue to function without a kidney is by beginning a patient on a form of dialysis. However, as with any treatment, there will always be a list of side …

Faculty and Student Publications

© 2020 by the authors. Licensee MDPI, Basel, Switzerland. In this paper we introduce a mechanistic model through which exercise may enhance episodic memory, specifically via attenuating proactive and retroactive memory interference. We discuss the various types of memory, different stages of memory function, review the mechanisms behind forgetting, and the mechanistic role of exercise in facilitating pattern separation (to attenuate memory interference).

The Impact Of Exercise In Spaceflight And Microgravity Environments, William Bybee

Mahurin Honors College Capstone Experience/Thesis Projects

Since mankind’s first spaceflight, a significant barricade in reaching distant planets has been the damaging effects of microgravity upon the human body. Effects range from loss in bone mineral density and severe muscle atrophy to autoimmune disorders. The most effective countermeasure of these effects to date is exercise. Implementation of exercise in microgravity is not an easy task, so various specialized equipment must be utilized to effectively administer it. Even with this equipment, exercise as it is currently used does not entirely prevent body systems from undergoing detrimental changes. New modalities and implementations are currently being investigated that may significantly …

Faculty Scholarship for the College of Science & Mathematics

The purpose of this cross-sectional study was to determine the differences in areal bone mineral density (aBMD) based on alcohol consumption behaviors, bone-loading history as assessed by a bone-specific physical activity questionnaire (BPAQ), and the body mass index (BMI). College-aged female students (N = 112) were recruited from the universities in Seoul and Gyeonggi province, South Korea. The aBMD of the lumbar spine and non-dominant side of the proximal femur (total hip, TH; femoral neck, FN; femoral trochanter, FT) were measured using dual energy X-ray absorptiometry (DXA). Alcohol consumption was determined by the frequency and amount of alcohol intake during …

Examining The Relationship Of Exercise And Sleep In Students Across Multiple Academic Disciplines, Taylor Zewe

Honors Projects

Students in college learn the importance of balancing their academic studies with their sleep and exercise habits. The amount of sleep and exercise a student recieves has been examined in previous research studies. In these studies it was found that exercise had a postive affect on the amount of sleep received. However, there is little research on the affect academic discipline has on sleep habits and/or exercise habits of students in college. The purpose of this study is to examine the sleep and exercise habits among students in multiple academic majors at Bowling Green State University.

The Impact Of Power Training On Balance And Visual Feedback Removal, Juliana Bouton

Senior Honors Theses

Because power training has been known to augment stability, the purpose of this study was to assess whether the removal of visual input affects lower limb muscle power production in young women who are resistance trained to the same degree it affects the untrained. This provided insight as far as the need for resistance training protocols in a largely untrained visually impaired population. To study this, fourteen college-aged female participants (18-23 years) performed a seated double-leg press on a leg sled machine, isolating power production of the lower limbs. After establishing baselines, which involved finding an average of power produced …

METHODS: Participants (8-12 weeks) completed assessments concerning their activity levels, as well as knowledge/beliefs regarding PA, during pregnancy. Next, participants were randomly assigned to either an intervention (IG) or control group (CG). The IG received educational information regarding PA during pregnancy, …

Association Between Perceived Physical Activity And Cognitive Function In Older Adults, Paul D. Loprinzi, Emily Frith

Faculty and Student Publications

© The Author(s) 2018. There is irrefutable evidence that regular participation in physical activity is favorably associated with numerous positive health outcomes, including cognitive function. Emerging work suggests that perceived physical activity, independent of actual physical activity behavior, is inversely associated with mortality risk. In this study, we evaluate whether perceived physical activity, independent of actual physical activity, is associated with cognitive function, a robust indicator of mortality risk. Data from the cross-sectional 1999–2002 National Health and Nutrition Examination Survey were employed (N = 2352; 60+ years of age). Actual physical activity was assessed via a validated survey. Perceived physical …

Interleukin-6 And Exercise; Early Evidence Of A Novel Myokine, Brendan Hogg Mr.

Graduate Student Theses, Dissertations, & Professional Papers

Interleukin-6 (IL-6) was first identified as a pleiotropic cytokine, with a host of body-wide functions. Cytokine functions are characterized by chronically elevated levels within various inflammatory states. In this regard, IL-6 is largely associated with the acute phase response to many stimuli and performs specific actions when produced from certain cell types. Accrued evidence indicates IL-6 release from skeletal muscle often includes myokine functions. Novel myokine functions are adaptive in nature, and as compared to inflammatory/cytokine roles, exhibit a transient time course. Following exercise plasma IL-6 peaks and returns to resting levels within 1-2 hours. In contrast, IL-6 is observed …

The Effect Of Insulin Treatment And Exercise Modality On Skeletal Muscle Fiber Size In Streptozotocin-Induced Type 1 Diabetic Rats, John Z. Nickels

Electronic Thesis and Dissertation Repository

Severe Type 1 Diabetes Mellitus (T1DM) is known to have several negative effects on skeletal muscle mass, a condition known as diabetic myopathy. One of these effects is the atrophy of the glycolytic muscle fibers. However, the role of intensity of insulin treatment and exercise modality in attenuating this loss in fiber cross-sectional area (CSA) specifically has yet to be determined. The purpose of this investigation was to determine the effects of 12 weeks of differing intensity of insulin therapy and exercise modality on the CSA of plantaris muscle fibers, identified by myosin heavy chain (MHC) of STZ-induced T1DM rats. …

Optimal Nutrition For Endurance Exercise: A Systematic Review, Sarah E. Andrus Ms, Bruce W. Andrus Md Ms

Dartmouth Scholarship

Introduction

As fatigue in endurance events correlates with depletion of muscle glycogen, the traditional approach to nutritional support has been carbohydrate loading. However, there has been recent interest in improving athletic endurance performance by novel diets in the days to weeks prior to endurance events, the pre-event meal, and during exercise.

Methods

We searched PubMed and SCOPUS for randomized trials published from 1992-2017 with a primary endpoint of endurance performance. We identified 407 citations which were examined against our inclusion criteria of randomization or crossover allocation to diet and for which a primary outcome was endurance performance.
