Waiting On The World (Of Allied Healthcare) To Change: How Undergraduate Preparedness Curriculum Dis/Includes Ability, Brianna Donnelly

West Chester University Doctoral Projects

Significant concerns for healthcare practitioners and allied health professionals continue to arise regarding treatment of persons with disabilities. Whether disability exists as apparent or non-apparent, temporary, or chronic, people with disabilities tend to be in poorer health and tend to use health care at a significantly higher rate than people who do not have disabilities. Importantly, the absence of professional training on disability competency issues for health care practitioners is one of the most significant barriers that prevent people with disabilities from receiving appropriate and effective health care. This qualitative narrative analysis explores the inclusion of disability concepts and people …

Effects Of Aging On Patellofemoral Joint Stress During Stair Negotiation On Challenging Surfaces, Nicholas Lynn Hunt

Boise State University Theses and Dissertations

Introduction: Patellofemoral pain is an incessant lower limb musculoskeletal disorder that may be underreported in older adults. During common locomotor activities, such as when negotiating stairs, older adults (over the age of 65 years) adopt knee biomechanics reported to increase patellofemoral pain. Negotiating stairs with a challenging surface, such as uneven or slick, may place greater demand on the knee and further exacerbate joint biomechanics related to PFJ stress. Yet, it is unknown if older adults exhibit increases in patellofemoral joint (PFJ) stress when negotiating stairs with challenging surfaces. Purpose: The purpose of this study was to examine the effect …

Mindfulness And Physical Activity As Moderators Of Behavioral Inhibition Sensitivity And Psychological Distress, Edward Silber

LSU Master's Theses

Framed in Reinforcement Sensitivity Theory, the current study examined the moderating effects of mindfulness and moderate-to-vigorous physical activity (MVPA) on the relationship between behavioral inhibition system (BIS) sensitivity and psychological distress. Participants (N=183) were college students at a large public university in the Southeastern United States. Data were collected using an online survey with self-report questionnaires that demonstrated acceptable reliability. Data analysis utilized multiple linear regression models to test study hypotheses. Findings revealed a significant positive relationship between BIS sensitivity and psychological distress, with mindfulness and MVPA significantly moderating this association. Specifically, increased reports of mindfulness and MVPA …

A Time-Course Characterization Of Muscle Function And Mitochondrial Markers During Colorectal Cancer-Induced Cachexia In Tumor-Bearing Male Mice, Ana Cabrera Ayuso

Graduate Theses and Dissertations

Cachexia is a multisystemic and multifactorial syndrome prevalent in cancer patients. It is clinically defined by involuntary loss of >5% weight in a six-month window, despite nutritional interventions. A negative energy balance characterizes cancer cachexia (CC), it is associated with weakness and fatigue in skeletal muscle. Impaired muscle function is associated with lower quality of life in cancer patients. Defects in mitochondrial function are strongly associated with muscle wasting. This study explored muscular contractile function and mitochondrial quality control (MQC) markers in soleus, gastrocnemius, and tibialis anterior (TA) muscles of C26-induced male tumor-bearing mice during a 25-day time course. It …

Leadership-As-Disciplinary Stewardship: A Social Movement For Kinesiology’S Future Success In The 21st Century University, Jenna R. Lorusso

Electronic Thesis and Dissertation Repository

Some scholars in kinesiology have advocated for the adoption of the leadership-as-disciplinary stewardship (LDS) construct as a way for the discipline to survive and thrive in the challenging 21^st Century university climate. Despite budding interest in LDS, there is a lack of empirical research on the construct and the limited conceptual literature lacks the specificity, practicality, and transformative quality necessary for realistic and fruitful application. This participatory research, informed by the social movement theory of collective action frames, investigated the meaning, need, development, and motivation of LDS in kinesiology by engaging 10 senior scholars from various countries and sub-disciplinary …

Neuromotor Control Of The Hand During Smartphone Manipulation, Prasanna Kumar Acharya

LSU Doctoral Dissertations

The primary focus of this dissertation was to understand the motor control strategy used by our neuromuscular system for the multi-layered motor tasks involved during smartphone manipulation. To understand this control strategy, we recorded the kinematics and multi-muscle activation pattern of the right limb during smartphone manipulation, including grasping with/out tapping, movement conditions (MCOND), and arm heights.

In the first study (chapter 2), we examined the neuromuscular control strategy of the upper limb during grasping with/out tapping executed with a smartphone by evaluating muscle-activation patterns of the upper limb during different movement conditions (MCOND). There was a change in muscle …

Comparing Knee Joint Mechanics Across Phases Of The Menstrual Cycle, Bethany Kilpatrick

Cal Poly Humboldt theses and projects

Anterior cruciate ligament (ACL) injuries are among the most commonly occurring knee injury. Compared to men in the same sports, females are two to eight times at higher risk for ACL injury. Research suggests that hormone fluctuations across the menstrual cycle (MC) play a crucial role in ACL injuries due to their effect on tendons and ligament's mechanical properties. PURPOSE: To examine knee joint laxity during dynamic movements across three-time points of the MC. METHODS: Seven young, healthy females with regular MCs performed three jump-landing tasks (double leg depth jump, single-leg lateral jump, and single-leg forward jump) across the early-follicular, …

The Effects Of Anterior Cruciate Ligament Thickness, Knee Joint Laxity, Activity Level, Neuromuscular Imbalances And Lower Extremity Muscular Activation Patterns On Anterior Cruciate Ligament Loading, Zachary A. Sievert

Human Movement Sciences & Special Education Theses & Dissertations

There are numerous known mechanisms of anterior cruciate ligament (ACL) injury risk that span from knee joint laxity to landing mechanics. However, the relationship of these mechanisms to ACL loading during landing is unclear. In addition to landing mechanics, anthropological aspects such as ACL diameter, which can now be obtained via ultrasound, may also be an important mechanism for ACL loading. However, the relationship between ACL diameter to ACL loading and landing mechanics remains unknown. This study was conducted with three primary purposes. The first purpose of this study was to examine the inter and intra-rater reliability of using ultrasound …

The Influence Of Time Spent In Beginning And End-State Postures On Grasp Choice, Rachel Modersitzki

Undergraduate Honors Capstone Projects

The choice to end comfortably often requires adoption of uncomfortable beginning states, demonstrating that a sequence of movement is planned in advance of movement onset. Many factors may influence the choice of comfortable end-state postures including the greater precision and speed afforded by postures at joint angle mid-ranges (Short & Cauraugh, 1999). There has been no evaluation of the hypothesis that postures are chosen based on minimizing time spent in postures. Typically, the time spent in beginning and end-states are not explicitly constrained, but the end-state posture is likely held for the longer amount of time due to greater precision …

How Do Social Norms Affect Physical Activity And Performance On An Endurance Task?, Keith David Randazzo

LSU Doctoral Dissertations

Despite the extensive benefits associated with a physically active life style, less than 50% of US adults engage in recommended levels of physical activity (PA), so finding ways to structure environments to promote PA is an important concern. Social norms, conceptualized as an individual’s perception of peer behavior, provide a framework for exploring factors that influence decisions to be physically active. Although researchers have investigated how social norms influence a variety of behaviors, the PA domain has not been fully explored. The focus of this dissertation is to apply social norms theories to investigate how normative information influences PA intentions …

Estimates Of Persistent Inward Current Decline In Human Soleus Motor Units During Fatigue, Kirby Mendes

Theses and Dissertations (Comprehensive)

Fatigue is defined as any exercise induced reduction in strength or power, and can be attributed to central and peripheral components. Many central and peripheral mechanisms have been extensively studied, but few studies have looked at the changes in the intrinsic properties of motor neurons and their contribution to fatigue. Persistent inward current (PIC) is an important intrinsic property of motor neurons responsible for setting a large increase in the gain of motor output and may contribute to fatigue. Inhibitory inputs such as reciprocal inhibition (RI) have been shown to turn off PICs and reducing the gain of output. PIC …

The Comparative Effects Of Hot Yoga And Thermoneutral Yoga On Flexibility, Heart Rate, Sweat Rate, And Mood, Hannah Kirkland Campbell

Graduate Theses and Dissertations

Yoga is an ancient Indian philosophy, described as a therapeutic intervention and health maintenance practice that unites the mind and body to aid healing through the combination of physical postures, breathing techniques, and meditation. There is ample research regarding yoga practiced in an environment that is thermoneutral, or in an environment that does not alter the metabolic heat production or evaporative heat loss of people. However, minimal research exists on the increasingly popular form of yoga known as hot yoga, or yoga practiced in an environment that is often humidified and 95° F or warmer. This exploratory study compared the …

Staff Perceptions Of Youth Recreation Programs, Lana L. Huberty

Culminating Projects in Kinesiology

In the past, recreation agencies defined their youth service mission as engaging children in fun and games. This mission involved keeping youth off the streets and out of trouble. However, expectations often were limited to opening facilities and hiring minimum wage, part-time employees to baby-sit the youth and facility. As programs have developed, and youth development professionals have acquired a more sophisticated understanding of the potential of youth programming, a new mission has evolved. This mission involves professional staff members including the youth in program planning and development. These programs also aim at teaching youth confidence, self-esteem and other non-traditional …
