International Journal of Exercise Science

International Journal of Exercise Science 13(4): 49-61, 2020. The barbell back squat provides a highly effective training stimulus to improve lower body strength, speed, and power, which are considered key components of athletic performance in many sports. The barbell hip thrust exercise utilizes similar musculature, and is popular among practitioners, but has received far less scientific examination. The purpose of this study was to evaluate the effects of an in-season resistance training program with hip thrusts or back squats on physical performance in adolescent female soccer players. Fourteen players completed identical whole-body resistance training twice per week for 6 weeks, …

Reliability And Test-Retest Agreement Of Mechanical Variables Obtained During Countermovement Jump, Alisson Alves Souza, Martim Bottaro, Valdinar Araujo Rocha Jr, Victor Lage, James J. Tufano, Amilton Vieira

International Journal of Exercise Science

International Journal of Exercise Science 13(4): 6-17, 2020. The countermovement jump (CMJ) is often used as performance measure and monitoring tool. Traditionally, jump height (JH) is most often studied and reported, but other variables (e.g. force, velocity, power) can also be obtained during CMJ testing on a force plate. The aim of this study was to determine the intra-rater reliability of mechanical variables obtained during CMJs. For this, 41 physically active men (24 ± 4 years) performed four CMJs on a force plate with an interval of 48 to 168 hours (test-retest design). Six variables were analyzed: 1) jump height …

Rate Of Perceived Exertion And Cardiorespiratory Fitness In Older Adults With And Without Alzheimer's Disease, Andrea Bevan, Eric Dennis Vidoni, Amber Watts

International Journal of Exercise Science

International Journal of Exercise Science 13(3): 18-35, 2020. Exercise has many benefits for physical and cognitive health in older adults, yet there are many barriers to exercise adherence in this population. Subjective perception of exercise difficulty, or rate of perceived exertion (RPE), may especially be a barrier to exercise in individuals with Alzheimer’s disease (AD), due to changes in initiation and motivation that accompany changes in cognition and brain function. RPE is the most commonly used measure of subjective effort in exercise research, yet the relationship between RPE and objective fitness is not fully understood in older adults. A better …

Post Exercise Hypotension Following Concurrent Exercise: Does Order Of Exercise Modality Matter?, Whitley J. Stone, Mark A. Schafer, Scott W. Arnett, Scott Lyons

International Journal of Exercise Science

International Journal of Exercise Science 13(2): 36-48, 2020. Cardiovascular (CV) and resistance training (RT) can moderate negative effects of aging, disease, and inactivity. Post-exercise hypotension (PEH) has been used as a non-pharmacological means to control and reduce BP. Few have evaluated PEH response following a bout of exercise combining CV and RT, whether or not there is an order effect, or if PEH continues when activities of daily living (ADLs) are resumed. Participants (N= 10) completed a non-exercise control, a graded exercise test (GXT), and two concurrent sessions (CVRT and RTCV). Each session was followed by a 60-minute …

New Author Guidelines In Statistical Reporting: Embracing An Era Beyond P < .05, Samantha Johnson, Whitley J. Stone, Jennifer Bunn, Scott Lyons, James W. Navalta

International Journal of Exercise Science

International Journal of Exercise Science 13(1): 1-5, 2020. Statistical reporting of quantitative research data has been plagued by potential bias and reporting suppression due to a single numerical output: the p-value. While there is great importance in its merit, creating a pass-fail system (set at point of .05) has created a culture of researchers submitting their project’s data to a filing cabinet if it does not yield “statistical significance” based on this value. The editors of the International Journal of Exercise Science are following the American Statistical Association’s call for statistical reform by adjusting our reporting guidelines to the …

Acute Exercise On Memory Function: Open Vs. Closed Skilled Exercise, Justin Cantrelle, Grace Burnett, Paul D. Loprinzi

Faculty and Student Publications

© 2020 The Author(s). Background: Previous studies suggest that acute exercise may improve memory function. Few studies, however, have investigated the differential effect of the acute exercise movement patterns on memory. Such an effect is plausible, as research demonstrates that open-skilled exercise (e.g., racquetball) may have a greater effect on memory-related neurotrophins (e.g., brain-derived neurotrophic factors) when compared to closed-skilled exercise (e.g. treadmill exercise). A key distinction between open- and closed-skilled exercise is that open-skilled exercises are those that require an individual to react in a dynamic way to a changing, unpredictable environment. Our aim in this study was to …

Nanoformulation Of The Superoxide Dismutase Mimic, Mntnbuoe-2-Pyp5+, Prevents Its Acute Hypotensive Response, Sarah L. Schlichte, Svetlana Romanova, Kenichi Katsurada, Elizabeth A. Kosmacek, Tatiana K. Bronich, Kaushik K. Patel, Rebecca E. Oberley-Deegan, Matthew C. Zimmerman

Journal Articles: Cellular & Integrative Physiology

Scavenging superoxide (O₂^•-) via overexpression of superoxide dismutase (SOD) or administration of SOD mimics improves outcomes in multiple experimental models of human disease including cardiovascular disease, neurodegeneration, and cancer. While few SOD mimics have transitioned to clinical trials, MnTnBuOE-2-PyP⁵⁺ (BuOE), a manganese porphyrin SOD mimic, is currently in clinical trials as a radioprotector for cancer patients; thus, providing hope for the use of SOD mimics in the clinical setting. However, BuOE transiently alters cardiovascular function including a significant and precipitous decrease in blood pressure. To limit BuOE's acute hypotensive action, we developed a mesoporous silica nanoparticle …

The purpose of this study was to utilize a validated screening tool to explore quantifiable presence of depression among college students who engage in recreational prescription opioid misuse (RPOM). Additionally, gender differences in depression and co-occurring substance use are examined. Methods: Students (n = 104) of a large …

Protocol Development And Optimization For Rnls Mouse Characteristic Assessment, Hasan Farid

Browse all Theses and Dissertations

Protocol development and optimization are vital in the scientific method process. By having accurate protocols, one can properly assess the characteristics of their animal model for any given experiment. One animal newly adopted in our lab was the novel regulatable nuclear localization sequence (rNLS) mouse model. This novel mouse model displays symptoms of Amyotrophic Lateral Sclerosis (ALS) and Frontotemporal dementia (FTD), after the accumulation of the hTDP-43 (TAR DNA-binding protein 43) aggregate in the central nervous system. The expression of this protein occurs after the removal of deoxycycline from the mouse’s food source. Once the removal of the drug, this …

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 …

Use Of Kalman Filtering In State And Parameter Estimation Of Diabetes Models, Cassidy Le

HMC Senior Theses

Diabetes continues to affect many lives every year, putting those affected by it at higher risk of serious health issues. Despite many efforts, there currently is no cure for diabetes. Nevertheless, researchers continue to study diabetes in hopes of understanding the disease and how it affects people, creating mathematical models to simulate the onset and progression of diabetes. Recent research by David J. Albers, Matthew E. Levine, Andrew Stuart, Lena Mamykina, Bruce Gluckman, and George Hripcsak¹ has suggested that these models can be furthered through the use of Data Assimilation, a regression method that synchronizes a model with a …

Seen In Science: Lgbtq+ Inclusivity In Anatomy & Physiology Texts, Harshini Sirvisetty, Kat Ray King, Linda Catherine Fuselier

Undergraduate Arts and Research Showcase

Biology is unique from other science disciplines in that concepts taught in core classes can inform our student’s understanding of sex and gender. A biology major encounters lessons on sex determination, sexual reproduction, and sex characteristics in their courses. The language used in these units matters. It is imperative that educators consider how the language, examples, and content that we use in classrooms drive (or not) inclusivity for gender- and sexuality-diverse (GSD) (aka LGBTQ+) individuals. We chose to analyze four college-level human anatomy/physiology (AP) textbooks for GSD population inclusivity. We adopted a queer theory framework to critically examine how sex, …

Testosterone And Interpersonal Attraction: A Placebo-Controlled Design, Stefan M. Goetz

Wayne State University Dissertations

Testosterone has long been implicated as a neuroendocrinological mechanism in the expression of reproductive strategies. Humans the world over form and maintain pair-bonds suggesting that pair-bonds may serve to enhance reproductive fitness. However, infidelity is a perennial threat to these bonds. The data in humans suggests that testosterone is associated with mate-seeking but may be detrimental to relationship maintenance. However, past work has relied on correlational studies and additional findings from nonhuman animal models suggest that acute changes rather than baseline concentrations in testosterone may in fact protect extant pair-bonds. The present research sought to test the causal role of …

Clinical Practice in Athletic Training

There are significant health risks associated with the female athlete triad (Triad), therefore early detection and prevention is key. Athletic trainers often serve as the frontline defense and can have a crucial role in identifying the Triad. Yet knowledge, confidence, and practice standards in the recognition, referral and treatment is lacking. The purpose of the following Quality Improvement document is to provide athletic trainers with a framework for improving Triad-specific knowledge, confidence, and practice standards. The 2014 Female Athletic Triad Coalition consensus statement provides an evidence-based risk stratification system for detection and referral of the Triad. The Coalition suggests including …

Point-Of-Care Research: Retrospective Analysis Of The Evaluation And Classification Of Tendon Pathology In Athletic Training, Ashley J. Reeves, Russell T. Baker, Scott W. Cheatham, Alan Nasypany

Clinical Practice in Athletic Training

Tendon pathology has been studied across healthcare professions but remains poorly understood. Imaging and clinical findings have been used to diagnose tendon pathology, but these findings are discrepant. It is vital that clinicians use sound clinical judgment to determine the most accurate clinical diagnosis and treatment options given documented clinical findings. The purposes of this study were to assess athletic trainers’: 1) documented clinical findings for patients presenting with tendon pain, 2) use of documented findings to inform clinical diagnosis of tendon pathology, and 3) change in tendon pathology classification when presented with a novel diagnostic term.

Functional Balance Assessment Of Firefighters During Mass-Screening Examinations, Rachel M. Eiler, Zachary K. Winkelmann, Kenneth E. Games

Clinical Practice in Athletic Training

Firefighters are tactical athletes who are required to complete rigorous tasks as part of their job functions. The focus of this clinical outcomes assessment was to assess functional balance assessment through the use of the anterior reach test with and without personal protective equipment (PPE) during a mass-screening examination. The screening was completed with 61 active firefighters in a local fire department with access to athletic training services. The results of the anterior reach assessment identified a significant difference of a firefighter’s anterior reach when donning and doffing PPE. Anterior reach distances were significantly reduced (P < 0.001) on the right leg with (mean = 55.78 cm ± 7.53 cm) and without PPE (mean = 58.92 cm ± 6.47 cm). Similarly, significant decrements (P = 0.003) in left leg anterior reach distance in firefighters donning (mean = 57.67 cm ± 8.25 cm) and doffing (mean = 59.82 cm ± 6.31 cm) PPE. Clinical application of these findings suggests that healthcare providers working with tactical athletes, specifically firefighters, should consider the risks associated with donning PPE such as functional balance deficits.

Deep Vein Thrombosis In Lower Extremity Of A Female Collegiate Volleyball Athlete: A Case Study, Lucas D. Dargo, Kendra Borton, Rachel Roths, Zachary Dougal

Clinical Practice in Athletic Training

Deep vein thrombosis (DVT) occurs when a blood clot forms in deep veins in the body, usually in the lower extremity. DVT is commonly seen in older or hospitalized patients. This case is unique because the patient is a 20-year-old female division III collegiate volleyball athlete, which is not the typical age or population affected by DVT or clotting disorders. The patient presented with swelling, pain, and decreased knee flexion (3/5) and plantarflexion (4/5) strength in her left lower extremity. These impairments reduced her ability to walk or run. The patient’s athletic trainer (AT) initially diagnosed her with a left …

Posterior Glenoid Dysplasia As A Secondary Finding To Labrum Tear And Subscapularis Strain: A Case Study, S. Andrew Cage, Brandon J. Warner, Diana M. Gallegos

Clinical Practice in Athletic Training

The purpose of this disablement model case study was to describe the case of a collegiate baseball pitcher suffering from a labral lesion and supraspinatus strain that may have been the result of posterior glenoid dysplasia. Despite gross instability and glenohumeral external rotation weakness, the patient was initially able to continue to pitch. While posterior glenoid dysplasia has been described in literature, there have not been studies that have evaluated soft tissue changes that may be associated with this bony morphology abnormality. In this case, the patient reported to the athletic training staff complaining of pain, tightness, and a “clunking” …

Glp-1 Mediated Diuresis And Natriuresis Are Blunted In Heart Failure And Restored By Selective Afferent Renal Denervation, Kenichi Katsurada, Shyam Sundar Nandi, Hong Zheng, Xuefei Liu, Neeru M. Sharma, Kaushik K. Patel

Journal Articles: Cellular & Integrative Physiology

BACKGROUND: Glucagon-like peptide-1 (GLP-1) induces diuresis and natriuresis. Previously we have shown that GLP-1 activates afferent renal nerve to increase efferent renal sympathetic nerve activity that negates the diuresis and natriuresis as a negative feedback mechanism in normal rats. However, renal effects of GLP-1 in heart failure (HF) has not been elucidated. The present study was designed to assess GLP-1-induced diuresis and natriuresis in rats with HF and its interactions with renal nerve activity.

METHODS: HF was induced in rats by coronary artery ligation. The direct recording of afferent renal nerve activity (ARNA) with intrapelvic injection of GLP-1 and total …

Squids Use Multiple Escape Jet Patterns Throughout Ontogeny, Carly A. York, Ian K. Bartol, Paul S. Krueger, Joseph T. Thompson

Biological Sciences Faculty Publications

Throughout their lives, squids are both predators and prey for a multitude of animals, many of which are at the top of ocean food webs, making them an integral component of the trophic structure of marine ecosystems. The escape jet, which is produced by the rapid expulsion of water from the mantle cavity through a funnel, is central to a cephalopod's ability to avoid predation throughout its life. Although squid undergo morphological and behavioral changes and experience remarkably different Reynolds number regimes throughout their development, little is known about the dynamics and propulsive efficiency of escape jets throughout ontogeny. We …
