Diurnal Regulation Of Exercise-Induced Myocardial Signaling And Transcription, Charli Aguilar

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction: Exercise is well known for its many benefits on the body and most notably the heart. Recent emphasis, and significant resources, have been dedicated to elucidating the molecular mechanisms through which exercise exerts its pluripotent beneficial effects on health and the prevention of disease. A continuous evolution in this field has sought to modulate and optimize exercise in various ways to maximize the benefits. In recent years, a growing appreciation for the impact of circadian rhythms has gained traction and their influence on many essential biological functions have been integrated into exercise physiology (i.e. - chrono-exercise), as well as …

Peripheral artery disease (PAD) is an atherosclerotic disease that impairs blood flow and muscle function in the lower limbs. A skeletal muscle myopathy characterized by mitochondrial dysfunction and oxidative damage is present in PAD; however, the underlying mechanisms are not well established. We investigated the impact of chronic ischemia on skeletal muscle microcirculatory function and its association with leg skeletal muscle mitochondrial function and oxygen delivery and utilization capacity in PAD. Gastrocnemius samples and arterioles were harvested from patients with PAD (n = 10) and age-matched controls (Con, n = 11). Endothelium-dependent and independent vasodilation was assessed in response …

Combined Effects Of Aerobic Exercise And 40-Hz Light Flicker Exposure On Early Cognitive Impairments In Alzheimer’S Disease Of 3×Tg Mice, Sang-Seo Park, Hye-Sang Park, Change-Ju Kim, Seung-Soo Baek, Song-Young Park, Cody Anderson, Myung-Ki Kim, Ik-Ryeul Park, Tae-Woon Kim

Health and Kinesiology Faculty Publications

Alzheimer’s disease (AD) is a progressive degenerative brain disease and the primary cause of dementia. At an early stage, AD is generally characterized by short-term memory impairment, owing to dysfunctions of the cortex and hippocampus. We previously reported that a combination of exercise and 40-Hz light flickering can protect against AD-related neuroinflammation, gamma oscillations, reduction in Aβ, and cognitive decline. Therefore, we sought to extend our previous findings to the 5-mo-old 3×Tg-AD mouse model to examine whether the same favorable effects occur in earlier stages of cognitive dysfunction. We investigated the effects of 12 wk of exercise combined with 40-Hz …

The Effects Of Wearable Health Technology On Cancer Survivors’ Physical Activity, Sedentary Behavior, And Weight: A Meta-Analysis, Daphne Blount, Rui Zhang, Anne Blaes, Zan Gao

International Journal of Physical Activity and Health

Wearable health technology (WHT) has been suggested as a health intervention in preventing or reducing health risk factors in clinical populations. Cancer survivors exhibit risk factors prior to cancer diagnosis and acquire comorbidities as a result of their treatment. These conditions may increase likelihood of cancer recurrence and reduce quality of life by inhibiting survivors’ physiological function and predisposing them to other maladies. Several studies have suggested WHTs as an intervention in mitigating these risks. However, there lacks a comprehensive review of the current evidence to determine the efficacy of WHT interventions. Thus, a literature search of WHT studies within …

Path Associations Between Preservice Physical Educators’ Beliefs About Epistemology And Their Value And Self-Efficacy For Sport Education And Teaching Games For Understanding, Ken R. Lodewyk

International Journal of Physical Activity and Health

Teachers’ beliefs about epistemology – that is, their personal broad mental representations about the nature of reality, knowledge, and how people know and learn – have been associated with the many educational outcomes both in the classroom and in physical education. Little is known about whether these beliefs predict physical educators’ value (i.e., interest, importance, like, and usefulness) and self-efficacy (i.e., confidence in performing) for using constructivist teaching models such as sport education and teaching games for understanding. As a result, this study examined path associations from beliefs about epistemology (epistemic worldviews and epistemological beliefs) to value and self-efficacy for …

Health and Kinesiology Faculty Publications

Prolonged sitting in a mild hypercapnic environment impairs peripheral vascular function. The effects of sitting interruptions using passive or active skeletal muscle contractions are still unclear. Therefore, we sought to examine the vascular effects of brief periods (2 min every half hour) of passive and active lower limb movement to interrupt prolonged sitting with mild hypercapnia in adults. Fourteen healthy adults (24 ± 2 yr) participated in three experimental visits sitting for 2.5 h in a mild hypercapnic environment (CO2 = 1,500 ppm): control (CON, no limb movement), passive lower limb movement (PASS), and active lower limb movement (ACT) during …

The Effect Of Task And Environment Constraints On Aquatic Locomotor Behavior: Qualitative Data Analysis, Ernani Xavier Filho, Edison J. Manoel

International Journal of Aquatic Research and Education

Many constraints (environmental, organismic, and task) act on all patterns of motor coordination, although their effects on swimming is less well understood. To this end, we carried out the current study with fifty-six participants, ages ranging from six to twelve years. The experimental tasks were created from the original task in which changes in task speed and environmental context were manipulated. Four aspects in the results were notable: a) a main trend was one of performance with the same developmental status among the tasks; b) when behaviour changed, this occurred due to environmental constraints, leading to more rudimentary patterns of …

Ability Of Lifeguards To Detect Submerged Manikins In Public Swimming Pool Environments, Élie Vignac, Pascal Lebihain, Brice Guignard, Natacha Heutte, Loic Le Minor, Bastien Soulé

International Journal of Aquatic Research and Education

To prevent drownings in public swimming pools (PSP), French legislation requires constant surveillance by state-certified lifeguards. While previous research showed that surveillance was not always effective, this article focuses on efficiency of surveillance when it is effective. We evaluated the ability of 4 volunteer professional lifeguards to detect a submerged manikin under controlled conditions. One hundred and eight (108) tests were carried out in 2 PSP. Four variables were controlled (i.e., distance, depth, surveillance station, attendance). Our results showed that rapid drowning detection was not exclusively linked to the individual detection capabilities of a lifeguard, but rather it emerged from …

Effective Lifeguard Scanning: A Review, Stephen J. Langendorfer Ph.D., Francesco (Frank) A. Pia Ph.D., Angela K. Beale-Tawfeeq Ph.D.

International Journal of Aquatic Research and Education

The purpose of this scientific review was to address the question of what evidence-based visual surveillance/scanning skills exist in the peer-reviewed scholarly literature. It is well known that lifeguards spend a majority of their on-duty time surveying bathers and swimmers in the water. Lifeguards need to quickly distinguish among swimmers in distress and drowning persons from other bathers in order to rapidly come to their aid to prevent drowning. To be able to accomplish this task, Signal Detection Theory reveals that lifeguards need specific and extensive training in identifying the behavioral patterns associated with drowning persons and swimmers in distress. …

Examining Youth Conceptualizations Of Water Safety Behaviors Among Participants In A Learn-To-Swim Program, Austin R. Anderson, Kristina R. Anderson, William D. Ramos, Angela K. Beale-Tawfeeq

International Journal of Aquatic Research and Education

Drowning represents a leading cause of unintentional deaths among children. Concomitantly, while formal swim instruction often incorporates water safety practices, the efficacy of these messages remains largely unexplored. This qualitative-based study sought to evaluate how youth apply learned water safety concepts when posed with a hypothetical aquatic scenario. Semi-structured interviews, augmented by use of a visual illustration prompt, were conducted with 29 participants of a youth Learn-to-Swim (LTS) program. Interviews assessed participants’ expressed water safety behaviors and were coded based on emergent themes. Findings indicated that most participants were able to identify a “struggling” swimmer in the dramatized illustration. When …

Disentangling The Role Of Religiosity In Human Papillomavirus Vaccination Amidst Covid-19 Pandemic, Ayokunle Olagoke, Brenikki Floyd, Rachel Caskey, Jennifer Hebert-Beirne, Andrew D. Boyd, Yamilé Molina

Health and Kinesiology Faculty Publications

Religion is a complex and sociocultural driver of human papillomavirus (HPV) vaccination decisions, but its exact role has been mixed/unclear. We used a cross-sectional study of 342 Christian parents to examine the associations between the three domains of religiosity (organizational, non-organizational, and intrinsic) and the intention to (i) seek HPV information and (ii) receive the HPV vaccine. Organizational religiosity was the only domain that was positively associated with information-seeking intention regardless of the type of covariates included. Mixed findings in the association between religiosity and HPV vaccination decisions may depend on the religiosity domain being assessed.

Parents and caregivers attending children’s swim lessons in July and August 2018 participated in a brief water-safety education program. A pre-post-test design evaluated "Theory of Planned Behavior" indicators to assess for changes. We found significant increases in scores related to water safety knowledge, attitudes on maintaining arms reach distance …

Honor Thyself, Alonzo O. Williams

Dance (MFA) Theses

The black male experience and identity in America are filled with complexity. We struggle to know ourselves. We work to see the way of love and the peace of an unviolated free spirit. We want to engage with ourselves with the highest degree of freedom and comfort, not to continue to question our identity in a life-threatening white patriarchal masculinity ideal. Honoring oneself from the lenses of the Reconstruction era of the United States is essential. Reconceptualizing this history explores the significance of emphasizing Reconstruction in my life as a black male to go through a process of self-discovery and …

Beginnings, Elizabeth Becker

Dance (MFA) Theses

Researcher Elizabeth Becker uses personal experiences of pregnancy alongside scholarly research on the developmental movement patterns of the human embryo, fetus, and newborn’s first year of life to explore the multiplicity of these movement patterns within and outside the womb. Becker explores the relationship between the fertilization, germinal, embryonic, and fetal stages in relation to a newborn and its mother. These movement patterns within the beginning stages of life are valuable to research because they simulate neurodevelopmental patterns, which help wire the central nervous system in early childhood. These movements also help lay the foundation for sensory-motor development and life-long …
