The Effects Of Dry Cupping Therapy On Touch Pressure Threshold In Collegiate Baseball Players., S A. Cage, R L. Peebles, J D. Volpi, L E. Trail, B J. Warner

Clinical Practice in Athletic Training

Introduction: Cupping therapy is a therapeutic modality that uses negative pressures to achieve therapeutic benefits. Various published studies report that cupping therapy decreases pain, increases range of motion, and improves blood flow. Previous studies also report an effect on tissue tenderness. However, there do not appear to be any studies assessing the effects of cupping therapy on touch pressure threshold, which measures skin sensitivity. Changes in touch pressure threshold may provide more information on the neurological effect cupping therapy has on treated tissues. The purpose of this study was to compare the effects of cupping therapy on touch pressure threshold …

Clinical Practice in Athletic Training

Background: Low back pain can be a tough injury to endure, especially in the growing high school athlete.3 LBP in a high school athlete can be caused by various factors, such as structural deformities, mobility deficits, and so much more. The majority of LBP in adolescents is nonspecific LBP, which is defined as LBP that does not cause systemic or structural changes.5 Nonspecific LBP is often a result of other etiologies such as hypermobile or hypomobile segments of the spine, hip mobility deficits, gait, sleeping positions, or improper weightlifting form. Differential Diagnoses: Other possible diagnoses of LBP in adolescents could …

Figure-8-Reconstruction Of Posterior Sternoclavicular Joint Dislocation 18 Days Post Initial Injury, M Suri, S Bunemann

Clinical Practice in Athletic Training

Introduction: Traumatic sternoclavicular joint injuries account for less than 3% of all traumatic joint injuries1. Although rare, posterior dislocation of the sternoclavicular joint has the potential to be life-threatening due to the proximity of vital structures posterior to the manubrium. This injury typically requires a high-energy force applied through the joint2. SC dislocations become increasingly difficult to reduce after 24 hours, so timely diagnosis and treatment are important. Glass et al. found mediastinal compression occurred 30% of the time with posterior dislocations. If left untreated, prolonged pressure on the superior mediastinum can cause erosion of the great vessels, tracheoesophageal fistula, …

How Aquatic Insects Mitigate Temperature-Oxygen Challenges Via Behavioral, Morphological, And Physiological Plasticity, Jackson H. Birrell

Graduate Student Theses, Dissertations, & Professional Papers

How do organisms respond to environmental challenges and to environmental change? These questions occupy a central place in ecology and answering them will help us to understand why species live where they do, how organisms are affected by human activities, and, ultimately, how to choose among alternative conservation strategies. These questions are difficult, however, for two reasons. First, environmental challenges often involve multiple, interacting stressors. Second, individual responses can be modified by behavioral, morphological, and physiological plasticity. My dissertation investigates how interactions between temperature and oxygen influence the performance and survival of aquatic insects and how plasticity allows individuals to …

A Picture Worth A Thousand Words: Factors Influencing Disability Accommodations, Alicia E. Martin

Cal Poly Humboldt theses and projects

Because not all disabilities look the same it is difficult to label a person with disabilities just by looking at them. Given that our knowledge, attitudes, and perceptions impact how we interpret our world and our willingness to act, people, including professors, may be biased toward providing accommodations for those with easily recognizable disabilities and biased against those with non-recognizable disabilities, and this may impact the disabled person’s ability to learn. This thesis aims to address whether professors’ disability-related attitudes, perceptions of accommodation reasonableness, and willingness to provide accommodations differ when the disability is recognizable (student is pictured in a …

Review Of Diagnostic Accuracy Of The Ottawa Knee Rules In Adult Acute Knee Injuries, Sean L. Glover, Amy M. Loveless, Sara A. Posson, Zachary K. Winkelmann

Clinical Practice in Athletic Training

Acute knee injuries are commonly found in athletic populations. The wide range of knee injuries can present a challenge deciding which injuries require imaging. Currently, radiography is considered the gold standard of imaging for knee fractures. However, imaging is often costly not only for the patient, but also for the healthcare system. Since imaging is expensive, it is critical that clinicians decipher which patients require such testing. The Ottawa Knee Rules (OKR) is a predictor tool created by Stiell et al in 1995 to help clinicians accurately distinguish potential knee fractures from non-fractures for imaging purposes. The OKR guidelines state …

The Effect Of Alkalinity On Lampricide Effectiveness And Gill Physiology In Invasive Sea Lamprey (Petromyzon Marinus), Alexandre J. Walsh

Theses and Dissertations (Comprehensive)

The pesticides, 3-trifluoromethyl-4-nitrophenol (TFM) and niclosamide are used to control populations of invasive sea lamprey (Petromyzon marinus) in the Laurentian Great Lakes of North America. Added to streams infested with larval sea lamprey, the effectiveness of these pesticides, commonly called lampricides, are strongly influenced by water pH, with greater toxicity for both TFM and niclosamide in lower pH than higher pH water. However, the TFM and niclosamide sensitivity of sea lamprey are also greater in poorly buffered, low alkalinity water than in high alkalinity water but it is unclear why. One goal of my thesis was to propose …

The goal of this study is to determine if physiologically relevant cholesterol levels and media types impact porin gene expression and antibiotic resistance in K. pneumoniae. To accomplish this, …

Elucidation Of The Role Of Agouti-Signaling Protein Throughout Folliculogenesis And Early Embryonic Development In Cattle, Heather L. Chaney

Graduate Theses, Dissertations, and Problem Reports (ETD)

The oocyte expresses certain genes during folliculogenesis to regulate the acquisition of oocyte competence. Oocyte competence, which refers to the presence of imperative molecular factors in the oocyte that are critical for high oocyte quality, is directly related to the ability of the oocyte to result in a successful pregnancy following fertilization. Over the past few decades, the development and optimization of assisted reproductive technologies, particularly in vitrofertilization, have enabled the beef and dairy industries to advance cattle genetics and productivity. However, only approximately 40% of bovine embryos will develop to the blastocyst stage in vitro. In addition, bovine embryos …

The Investigation Of Novel Bovine Oocyte-Specific Long Non-Coding Rnas And Their Roles In Oocyte Maturation And Early Embryonic Development, Jaelyn Zoe Current

Graduate Theses, Dissertations, and Problem Reports (ETD)

Early embryonic loss is a significant factor in livestock species' infertility, resulting in an economic deficit. In cattle, the in vivo fertilization rate is ~90%, with an average calving rate of about 55%, indicating an embryonic-fetal mortality rate of roughly 35%. Further, 70-80% of total embryonic loss in cattle occurs during the first three weeks after insemination, particularly between days 7-16. Growing evidence indicates that the oocyte plays an active role in regulating critical aspects of the reproductive process required for successful fertilization, embryo development, and pregnancy. However, defining oocyte quality remains enigmatic. Recently, many have abandoned the notion that …

Longitudinal Sport Science Implementation In American Collegiate Men’S Basketball, Jason Stone

Graduate Theses, Dissertations, and Problem Reports (ETD)

The expanding opportunities to implement sport science frameworks in elite-level basketball environments coincide with the sport’s increasing global prominence. Concomitant to these opportunities is the continual growth of the sport technology market (e.g., wearables, force plates) and computational power (e.g., data management tools, coding capabilities), which yields solutions and challenges for both athletes and practitioners. Due to the rapid influx of new sport technologies in high performance environments, particularly American Collegiate Men’s Basketball, more formal and ecologically valid research on how to effectively utilize data derived from them, particularly over long periods of time (i.e., multiple seasons) is needed. To …

Sex Differences In Endothelial Function, Metabolism, And Sleep: Responses To Disrupted Circadian Rhythms, Olga Hecmarie Meléndez-Fernández

Graduate Theses, Dissertations, and Problem Reports (ETD)

Circadian rhythms are endogenous cycles that recur approximately every 24 h, and manifest in virtually every physiological and behavioral process among the vast majority of organisms. These rhythms, sustained by the central circadian clock, the suprachiasmatic nucleus (SCN) of the hypothalamus, allow for optimal timing of biological processes that ensure organisms’ homeostasis, and are entrained to precisely 24 h by daily exposure to light. Disruption of the molecular mechanisms that drive these rhythms have negative consequences on physiology and behavior that may impair survival. The molecular mechanisms that underlie these effects are widely studied and linked to multiple diseases and …

Most Army ROTC programs conduct physical training (PT) only 3 days per week and no study has directly compared the effects of conducting PT 5 days per week on ACFT scores, ruck march performance, and aerobic capacity. Past research has indicated greater performance adaptations with a concurrent training program and some research has shown that current ROTC PT programs may not be optimal in physically preparing ROTC cadets. Purpose: To examine the effectiveness of a 5-day per week periodized tactical strength and conditioning program on ACFT scores, and aerobic capacity in Army ROTC cadets. Methods: Eight ROTC cadets from UNI …

Association Between Baseline Field Test Performance And Match Physical Performance In D1 Female Soccer Players, Benito Joel Cecenas

Graduate Student Theses, Dissertations, & Professional Papers

Background: Fitness testing is utilized by numerous soccer programs as a means for evaluation of player physical capacity. Previous literature has shown Yo-Yo Intermittent Recovery Test Level 1 (YYIR1) performance is associated with match physical performance in elite adult and youth soccer players. Until now, these relationships have not been investigated in the collegiate soccer setting, despite the YYIR1 being regularly utilized at the collegiate level to determine eligibility for competition, influence playing time, and to assess adaptation to training programs. For these reasons the association between the YYIR1 and match physical performance was investigated in women’s collegiate soccer.

Quantifying Life History Energetics Of An Oviparous Elasmobranch Subject To Future Warming Water, Carolyn R. Wheeler

Graduate Doctoral Dissertations

Marine ectothermic fishes – fishes that do not regulate internal body temperature independent from the water temperature – are some of the most vulnerable organisms to rapid and alarming increases in environmental temperature occurring due to climate change mediated-ocean warming. For tropical fish species that live near their thermal maxima, this warming could be of grave consequence to individuals, populations, and whole marine ecosystems. Certain key life stages such as embryos and reproducing adults may be particularly vulnerable to warming given the excess energetic costs of these life stages, which may disallow compensation for extreme changes in temperature. One taxonomic …

A Systematic Review Of The Effects Of Meditative And Mindful Walking On Mental And Cardiovascular Health, Dustin W. Davis, Bryson Carrier, Kyle Cruz, Brenna Barrios, Merrill Russen Landers, James W. Navalta

International Journal of Exercise Science

International Journal of Exercise Science 15(2): 1692-1734, 2022. Meditative and mindful exercise are types of physical exercise during which people pay attention, on purpose, to each new present moment without judging their experience. The goal is to apply an accepting awareness of the environment, bodily sensations, thoughts, and emotions without labeling them (e.g., good or bad). The literature centers on qigong, tai chi, and yoga, which are types of mindful exercise that improve mental and cardiovascular health. It is unclear if meditative and mindful walking also improve these health domains. To the authors’ knowledge, this question has not been addressed …

Heat Stressed Exercise Elicits Shifts In Cooling Strategies Across Body Mass In Tropical Songbirds, Kristen Dee Oliver

Biology ETDs

In resting animals, water use positively correlates with metabolic rate, for example smaller animals using proportionally more water per gram of body mass. However, animals also must endure heat and exertion, and evaporative cooling requires additional water use that may not scale similarly with body size. How evaporative water loss allometrically scales with body mass during heat-stressed exercise is poorly resolved, particularly for birds, yet is critically important for understanding the consequences of climate warming on the fitness of bird populations. Here, we evaluated how air temperature (T_a) influenced evaporative water loss during exercise (EWL_exercise) across …

Physical Activity Independently Predicts Perceived Stress During The Covid-19 Pandemic In Private University Students, Curtis W. Brownell, Laura S. Kabiri, Cassandra S. Diep, Heidi Y. Perkins, Amanda M. Perkins-Ball, Augusto X. Rodriguez

International Journal of Exercise Science

International Journal of Exercise Science 15(7): 1680-1691, 2022. Physical activity has significantly declined during the COVID-19 pandemic. Declines in physical activity have correlated with increased levels of perceived stress, though studies examining physical activity and stress have failed to account for critical confounds. The present study aims to determine whether physical activity independently predicts perceived stress in students attending private four-year universities. Physical activity, socioeconomic status, resilience, gender, and perceived stress data were collected from 85 students and used in a multiple linear regression analysis.
