Skin Pigmentation And Arterial Stiffness In Young Health Black And White Adults, Zoe R. Lincoln Apr 2022

Skin Pigmentation And Arterial Stiffness In Young Health Black And White Adults, Zoe R. Lincoln

Honors College Theses

Cardiovascular disease (CVD) is currently the leading cause of death worldwide, killing over half a million people in the US every year. This issue is only becoming more prominent, as both the world and US population are experiencing increased rates of CVD risk factors such as hypertension, type 2 diabetes, and obesity. Black Americans specifically are experiencing increased rates of these risk factors, possibly due to lifestyle, socioeconomic, and genetic variables, ultimately leading to a higher prevalence of CVD in this population. One possible mechanism for this health disparity is racial differences in skin pigmentation, which can influence cardioprotective Vitamin …

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 Apr 2022

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 …

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. Mar 2022

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. …

Chronic kidney disease is a progressive, incurable condition that involves a gradual loss of kidney function. While there are no non-invasive biomarkers available to determine whether individuals are susceptible to developing chronic kidney disease, small RNAs within urinary exosomes have recently emerged as a potential candidate to use for assessing renal function. Ultracentrifugation is the gold standard for urinary exosome isolation. However, extravesicular small RNA contamination can occur when isolating exosomes from biological fluids using ultracentrifugation, which may lead to misidentifying the presence of certain small RNA species in human urinary exosomes. Therefore, we characterized human urinary exosomal preparations isolated …
