The Associations Of Cardiovascular Disease, Physical Activity Intensities, And Measures Of Obesity On Static Balance In Middle-Aged And Older Adults, Hannah Martha Twiddy

Human Movement Studies & Special Education Theses & Dissertations

The burden of falls is widely known in older adults, though less research has targeted middle-aged adults (40-64 years of age), particularly at the population level. The purpose of this dissertation was to explore the roles of cardiovascular disease, physical activity (PA) intensity, and body anthropometrics on balance among middle-aged adults. Study 1 sought to determine if balance was impaired in middle-aged adults with poor ankle-brachial pressure index (ABPI), a marker of cardiovascular disease. Study 2 determined the associations between PA intensity with odds of having good static balance. Study 3 explored how strongly a variety of anthropometric measures, including …

Methods: Twenty-one adult LLP users (8 female, 13 male; 85% at K3 level; mean age=50.5) were recruited from prosthetic clinics in the Southern Nevada region. Verbal interactions between LLP users and their prosthetists (mean experience=10 years, range=4-21 years) during …

Effects Of A Remote Exercise Intervention On Aerobic Endurance In Individuals With Down Syndrome, Andrew Murata, Elena Wolf, Jonathan Crimm, Benjamin Lee

UNLV Theses, Dissertations, Professional Papers, and Capstones

Purpose: Down syndrome (Ds) or Trisomy 21 is a common genetic birth condition, and those with Ds typically display decreased cardiorespiratory fitness compared to those without Ds, potentially leading to an increased risk for cardiovascular conditions and mortality. Low cardiorespiratory fitness is partially caused by low physical activity levels in this population. The COVID-19 pandemic caused community-based activity programs to shut down, as individuals with Ds are at increased risk for COVID-19 hospitalization and death. Thus, it was vital to explore alternatives of in-person exercise during the pandemic. The purpose of this study was to investigate the effects of a …

The Effect Of Attachment Design And Aligner Material On The Efficiency Of Maxillary Canine Distalization In Premolar Extraction Cases, Najem Anbari

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background: Clear Aligner Therapy (CAT) is regarded as a popular esthetic alternative to conventional orthodontic treatment with fixed labial appliances. The mechanism of action, force delivery and limitation of this treatment modality remain largely unknown despite its popularity, the high demand and the relatively long evolutionary track of clear aligners. There are only few studies that addressed the elements that influence the efficiency of clear aligners, namely, the attachment design and aligner materials. It is widely believed that clear aligners are not suitable for extraction cases due to their lack of control over the root movement.

Methods: Participants were 13 sedentary individuals with 8+ migraines/month (age = 30 ± 11 yrs, 167 ± 6 cm, 86 ± 28 kg). Participants were categorized into morning-/evening-types based on the Morning/Eveningness Questionnaire and instructed to complete 1 month of …

Attentional Focus And The Development Of Skilled Performance, Harjiv Singh

UNLV Theses, Dissertations, Professional Papers, and Capstones

A central question in the development of skilled movement is: how a performer should focus their attention while preparing for the execution of a motor skill? Considerable evidence has shown that directing attention towards an intended movement effect (i.e., external focus) results in performance benefits relative to focusing on body movements (i.e., internal focus). While most of the previous research has emphasized the effects of internal versus external foci, evidence also suggests that external foci located at greater distances from the body (distal foci) are more effective than external foci located in greater proximity to the body (proximal foci) and …

Examining The Relationship Between Heart Rate And Perceived Exertion During A Division Iii Women’S Basketball Season, Natalie Hoffman, Taylor Vines, Mikayla Roman

21st Annual Celebration of Undergraduate Research and Creative Activity (2022)

BACKGROUND: “Internal load” represents the physiological and psychological stress experienced by athletes during training and competition. The ability to accurately monitor and assess an athlete’s internal load can be valuable for both training purposes and injury prevention. Advances in wearable technology provide the ability to objectively quantify an athlete’s internal load via the continuous measurement of heart rate (HR). This HR data can be used to determine an athlete’s training impulse (TRIMP) which is a validated measure of internal load. An athlete’s ability to self-monitor their perceived exertion during practice (sRPE) might also prove helpful in assessing internal load. However, …
