The Effects Of A 40-Minute Bout Of Aerobic Exercise On State Anxiety In College Age Individuals, Rachael Dozier

Online Theses and Dissertations

The purpose of this study was to determine if a forty-minute bout of aerobic exercise would decrease the state anxiety and heart rate of college aged individuals. This study was prompted due to the higher levels of anxiety in college aged individuals found in literature (Silva & Tucci, 2018). Specifically, college students need healthy alternatives to cope with their anxiety instead of turning to alcohol. Heightened levels of anxiety in this age range have been shown to increase negative coping habits, such as drinking, drugs, and eating disorders. These negative habits not only affect the individual physically, but also can …

Lumbar spine stability is regularly studied by positioning different loads at different heights and distance and measuring trunk muscle activation changes. Some of these studies have reported sex differences, but this needs to be revisited while controlling for confounding factors.

Method

20 males and 20 females sustained three static standing postures, with various loads (0, 5 and 10% of body weight), to evaluate the effect of height and distance. Activation of 12 trunk muscles was recorded with surface electromyography (EMG).

Results

Females activated their external obliques a little more than males, with increases ranging between 1.5 and 2.3% of …

An Evaluation Of Induced Shear Stress On Endothelial Cellular Adhesion Molecules, Edward B. Crabb

Theses and Dissertations

The pathophysiology of atherosclerotic cardiovascular disease (CVD) is highlighted by vascular dysfunction and low-grade vascular inflammation. Furthermore, the site-specific distribution of atherosclerosis throughout the arterial vasculature is primarily determined by local hemodynamic force. Therefore, this dissertation outlines three experiments designed to investigate the role of acute mental and physical (i.e., aerobic exercise), and vascular wall shear stress (SS) on the inflammatory aspects of atherosclerosis. Chapter 2 examines the effect of acute laboratory-induced mental stress on intracellular pro-inflammatory signaling pathways in peripheral blood mononuclear cells. Chapter 3 investigates the impact of acute laboratory-induced mental stress and maximal aerobic exercise on the …

Contralateral Repeated Bout Effect Of The Elbow Flexors Not Observed In Young Women, Bailey Brown

Honors Theses

The contralateral repeated bout effect (CL-RBE) is known as a protective effect in which an initial bout of eccentric exercise reduces muscle damage in the contralateral limb after a similar bout of eccentric exercise. To our knowledge, previous studies on CL-RBE only recruited males or a mixture of both sexes. PURPOSE: To investigate the presence of the CL-RBE of the elbow flexors in women. METHODS: Twelve healthy women (20.9 ± 2.5 years) performed two bouts of 45 maximal eccentric contractions (ECC) of the elbow flexors using the opposite arm separated by 14 days. The isokinetic muscle strength (60°/sec) was measured …

The Impact Of Flexibility On Balance In Rifle Athletes, Ileia Nagelkirk

Williams Honors College, Honors Research Projects

Research has shown that there may be a connection between flexibility and balance when evaluating fall risk in older adults and flexibility’s effect on a balance test (Emilio, Hita-Contreras, Jiménez-Lara, Latorre-Román, & Martínez-Amat, 2014); Overmoyer & Reiser, (2015). Balance is an important component of many sport movements, and has been shown to be particularly important in shooting performance in both novice and Olympic rifle athletes (Mononen, Konttinen, Viitasalo, Era, 2007; Ball, Best, Wrigley, 2003). The purpose of this study was to find if there was a relationship between a rifle athlete’s flexibility and their balance ability, to determine if flexibility …

The Effects Of Concussion On Tandem Gait Performance With Secondary Cognitive Tasks, Angel Lomeli

Cal Poly Humboldt theses and projects

Identifying concussions occurs with a battery of cognitive and motor tests. However, these tests are performed independently as primary tasks. Research has demonstrated amplified motor differences due to concussion when performing simultaneous cognitive tasks (i.e. dual-tasks). The Tandem Gait Test (TGT) is used in concussion assessment and has only moderate sensitivity and specificity alone. The aim of this study was to determine the effect of concussion on TGT performance with secondary cognitive tasks. Six concussed participants (age 22.6 ± 2.8) and fourteen healthy participants (age 23.8 ± 2.7) were recruited through the North Coast Concussion Program within 13 days (7 …
