The Contribution Of Psychophysiological Stress Factors On Muscle Cramp Susceptibility, Lauren D. Levine

UNLV Theses, Dissertations, Professional Papers, and Capstones

Exercise-associated muscle cramps (EAMCs) are painful phenomenon that involves involuntary muscle spasms occurring during physical activity or directly after. 1 The landscape of the research on EAMC etiology has expanded from focusing on a single prevailing cause (e.g., hydration status) to a more holistic approach of how numerous factors contribute to the onset of neuromuscular fatigue, and the significance of each factor in those who suffer from EAMC. Following the multifactorial theory of cramp pathophysiology, this research sought to advance the knowledge of cramp susceptibility by investigating if there is a relationship between common psychophysiological factors like high anxiety, sleep …

Comparison Of Gluteal Muscle Central Activation In Individuals With And Without Patellofemoral Pain, Michael Carpio, John S. Donohue, Jacob P. Kissman

UNLV Theses, Dissertations, Professional Papers, and Capstones

Purpose/Hypothesis: Individuals with patellofemoral pain (PFP) often present with knee valgus during weight-bearing activities. Weakness in the gluteal muscles is thought to contribute to this condition, but recent studies suggest that hip weakness might be a secondary problem in this population. Central nervous system adaptations have been noted in persons with PFP, which can lead to altered muscle function, faulty movement patterns, and poor function. Experimentally, central activation can be quantified by a central activation ratio (CAR) via superimposed burst (SIB) during a maximum voluntary isometric contraction (MVIC) where the ratio of volitionally activated motor units to total motor units …

The Relationship Between Concussion History And Lower Extremity Biomechanics During A Land And Cut Task, Nghi G. Vu, Warren O. Forbes, Jason M. Avedesian

Undergraduate Research Symposium Posters

In high impact landing tasks, athletes with a history of sports related concussion (SRC) have been found to demonstrate lower extremity (LE) biomechanics that are associated with elevated injury risk. However, the exact relationships between SRC history and LE biomechanics are inconclusive.

Designing A Mechanical Linkage Capable Of Decreasing Force Transfer From The Facemask To The Protective Helmet When Loading Occurs, Levi Hansen

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction

Sports that involve extensive personal contact have a high incidence of injury. The introduction of regulations mandating the use of personal protective equipment in these sports is the most common injury control strategy (Marshall et al., 2002). Negligible attention has been paid to the mechanical linkage between the facemask and helmet as a means of reducing force transfer from the facemask, through the helmet, and to the head and or neck of the athlete.

Methods

A novel prototype mechanical linkage of reasonable simplicity that provides 360° of freedom in motion capable of decreasing force transfer from the facemask to …

Dietary Supplement Increases Plasma Norepinephrine, Lipolysis, And Metabolic Rate In Resistance Trained Men, Richard Bloomer, Kelley Fisher-Wellman, Kelley Hammond, Brian K. Schilling, Adrianna Weber, Bradford Cole

Kinesiology and Nutrition Sciences Faculty Research

Background

Dietary supplements targeting fat loss and increased thermogenesis are prevalent within the sport nutrition/weight loss market. While some isolated ingredients have been reported to be efficacious when used at high dosages, in particular in animal models and/or via intravenous delivery, little objective evidence is available pertaining to the efficacy of a finished product taken by human subjects in oral form. Moreover, many ingredients function as stimulants, leading to increased hemodynamic responses. The purpose of this investigation was to determine the effects of a finished dietary supplement on plasma catecholamine concentration, markers of lipolysis, metabolic rate, and hemodynamics.

Methods
