The Effects Of Eating Disorders And Menstrual Irregularity On Bone Mineral Density In Sorority Women: A Cross-Sectional Study, Rachel Robertson

Honors Theses

Past research has reported bone loss among women diagnosed with eating disorders as a direct result of estrogen imbalance (Cobb et al., 2003; Gibson et al., 1999; Kim et al., 2012; Zuckerman-Levin et al., 2014). Menstrual irregularity may result from estrogen imbalance, which is characteristic of an eating disorder and ultimately causes bone loss. Past studies have focused on this three-way relationship between eating disorders, menstrual irregularity, and bone mineral density (BMD) specifically in female athletes (Cobb et al., 2003; Gibson, Mitchell, Reeve, & Harries, 1999) but rarely in recreationally trained or sedentary females. Previous research has also focused on …

A Comparison Of Warm-Up Modalities On Upper Body Force Production Measures, Mary G. Langford

Honors Theses

Warm-ups are often initiated before an athletic event in order to prepare the athlete's body for competition by increasing blood flow to the working muscles. When a warm-up also activates nerve-muscle function, producing a level of high-intensity power even after the muscle contraction occurs, it is known as post-activation potentiation (PAP). Most PAP warm-ups include high-load, low-velocity conditioning contractions whereas a low-load, high-velocity conditioning contraction may be a more user-friendly warm-up. Therefore, the purpose of this study was to investigate the effects of PAP after low-load, high-velocity conditioning contractions on subsequent upper body power exercises. Ten recreationally trained males (age: …

Investigating The Relationship Between Personality Traits And Athletic Performance Among Elite Hockey Players, Brittney H. Conway

EWU Masters Thesis Collection

"An interesting trend in the personality literature has been the assessment of the relationship between personality traits and athletic performances. In non-sport settings, the conscientiousness trait has been found to be strongly related to a number of good outcomes including job and training proficiency, academic performances, and physical activity (Barrick & Mout, 1991; Poropat, 2009; Rhodes & Smith, 2006). In the athletic setting, similar findings have been found with soccer players (Piedmont, Hill, & Blanco, 1999), football players (Tran, 2012) and Division 1 collegiate athletes (Saale-Prasad, 2014). However, in professional hockey these findings have generally not been replicated (Karp, 2000; …

Online Learning And The Effects On Functional Health: A Pilot Study, Jessica Mangis

EWU Masters Thesis Collection

"Online learning presents a major risk on our emotional and physical health, otherwise known as functional health which results in a trend away from active leisure pursuits and recreational sports and leading us towards a sedentary lifestyle (Wang, Luo, Gao, & Kong, 2012). Sedentary behavior leads to many health risks and conditions such as cardiovascular disease, one of the leading causes of death. A sedentary lifestyle is defined as someone who does not meet the minimum suggested levels of physical activity: 150 minutes of endurance training and two days of strength training a week (American College of Sports Medicine, 2011; …

Upper Extremity Strength And Power Field Tests As Predictors Of Pole Vault Performance In Female Collegiate Athletes, Carmen Schluter

EWU Masters Thesis Collection

"The purpose of this study was to determine if select upper-extremity strength and power field tests, and the test battery, predict pole vault performance in female pole vaulters. There is very little research on female pole vault athletes, specifically non-elite athletes. Field tests previously shown to be predictive of performance in males were examined to determine if they were also predictive for females. Four tests were used (8 lb backwards medicine ball (MB) throw, 3 m seated rope pull, three pull-ups for time, and maximum pull-ups) to determine if pole vault performance (season personal record for each athlete) could be …

The Effects Of A Low Back Pain Vibration Modality On Trunk Postural Control, Adam R. Cornwall

Theses and Dissertations (Comprehensive)

Abstract

Introduction: Low back pain (LBP) is prevalent worldwide and is affecting even more individuals as the population ages. There has recently been an increase in production of low back pain (LBP) vibration modality belts that apply localized vibration to the lumbar region of the spine as it has shown to reduce pain. However, vibration is also known to perturb muscle spindles and thus interfere with proprioception. If a LBP vibration modality causes a proprioceptive deficit in the trunk lumbar region it could potentially increase an individual’s risk of injury due to poor postural control. Therefore, the effects of a …

The Effects Of Manipulated Somatosensory Input On Simulated Falls During Walking, Sarah Mitchell-Ewart

Theses and Dissertations (Comprehensive)

Previous research has demonstrated that there is a distinct relationship between aging and instability. The somatosensory system plays a significant role in balance control in conjunction with vision and the vestibular system (Qiu et al., 2012). Evidence has shown that manipulation of the mechanoreceptors on the plantar surface of the foot has a direct effect on balance control. By manipulating these receptors with hypothermic anesthesia and vibration, researchers are capable of simulating the effect of sensory modification on healthy individuals, in order to understand the role that plantar-surface sensation has in adapting to perturbation during gait (Perry et al., 2001; …

Relationships And Sports: Mechanisms In Relational Motivation And Its Impact On Athletic Performance, Alexandra Szarabajko

Online Theses and Dissertations

Relationally-Autonomous Reasons (RARs) for pursuing goals are motives that take one’s own personal needs and the needs and desires of close others into account. These relational reasons motivate people in pursing health, school, or sports goals. The purpose of this study was to identify what mechanisms drive relational motivation that in turn affects athletic performance. Participants (n = 156) in this study were student-athletes from various sports, who completed a questionnaire. Athletic performance was obtained and standardized through each athlete’s performance statistics within their sport. The results of the study revealed that closeness, support, accountability, and shared values predicted relational …

The Effects Of External Focus Of Attention Exercise Rehabilitation On Dual Task Walking In Parkinson's Disease, Eric N. Beck

Theses and Dissertations (Comprehensive)

Parkinson’s disease impairs control of well-learned movements, and therefore, individuals with Parkinson’s disease are forced to walk with greater conscious control. This causes difficulties while walking and completing a secondary task simultaneously (dual tasking), in that distractions from conscious control of walking increase the risk of falls and injury. Although, attention-based exercise may be a potential avenue to decrease the demands associated with walking in Parkinson’s disease. For example, an external focus of attention (on manipulated objects) has been found to recruit the networks that are important for walking with little conscious control (automatic control networks). In contrast, an internal …

The 2d:4d Ratio, Handedness, And Sex Across The Age Span, Helen A M Protopapas Ms.

Theses and Dissertations (Comprehensive)

The ratio of the difference between the 2nd and 4th digits of the hand (2D:4D ratio) has been demonstrated to be an indirect indicator of prenatal testosterone levels. Prenatal testosterone has been found to play a role in brain development in utero, and thus may influence lateral asymmetries, such as handedness. Consequently, one of the aims of the current study was to examine relationships between the 2D:4D ratio, hand preference, and hand performance with the factors of sex (males and females), handedness (right handers and left handers), and age considered. A total of 104 participants were tested, 90 right handers …

Treadmill-Based Perturbation Training For Preventing Falls Among Young Adults, Patrick Anthony Cereceres

Open Access Theses & Dissertations

Falls present a serious challenge not only among older adults, but for young adults, especially those whose working conditions exposes them to a high fall hazard. Treadmill-based perturbation training, as a task-specific training modality, has emerged as a new paradigm used to prevent falls. However, the training program in previous studies contained up to 30 perturbation trials. It is unclear if a reduced number of perturbation trials could still induce positive effect in preventing falls. The purpose of this study was to investigate the effect of a treadmill-based perturbation training paradigm consisting of 8 slip perturbations on reducing slip-related falls …

The Acute Relationships Between Affect, Physical Feeling States, And Physical Activity In Daily Life: A Review Of Current Evidence, Yue Liao, Eleanor T. Shonkoff, Genevieve F. Dunton

Kinesiology Faculty Publications & Presentations - Archive

Until recently, most studies investigating the acute relationships between affective and physical feeling states and physical activity were conducted in controlled laboratory settings, whose results might not translate well to everyday life. This review was among the first attempts to synthesize current evidence on the acute (e.g., within a few hours) relationships between affective and physical feeling states and physical activity from studies conducted in free-living, naturalistic settings in non-clinical populations. A systematic literature search yielded 14 eligible studies for review. Six studies tested the relationship between affective states and subsequent physical activity; findings from these studies suggest that positive …

The Feedforward And Feedback Controls On Gait In Adults With Diabetes, Chun-Kai Huang

Theses & Dissertations

There are nearly 26 million people with diabetes mellitus (DM) in the US, and half of chronic DMs develop somatosensory deficits due to diabetic polyneuropathy or diabetic peripheral neuropathy (DPN). The absence or impaired somatosensory feedback (e.g. touch sensation or joint proprioception) resulted from the damage of large nerve fiber, and motor deficits such as attenuated muscle strength and abnormal plantar pressure of lower extremity have been identified in DPN, and these sensorimotor impairments lead to an increased number of falls. To reduce the risk of falling, a well-coordinated and adapted limb movement driven by the feedforward (anticipatory) and feedback …

Increased Minimum Toe Clearance Variability In Patients With Peripheral Arterial Disease, Troy Rand, Shane R. Wurdeman, Jason M. Johanning, Iraklis Pipinos, Sara A. Myers

Journal Articles

Individuals with peripheral arterial disease (PAD) report difficulty walking and experience 73% more falls than their healthy counterparts, but no studies have investigated functional mechanisms contributing to increased falls. Minimum toe clearance (MTC) is the minimum vertical distance between the toe of the swinging leg and the walking surface when the leg is swinging, and decreased values are associated with an increased risk for falls. This study is the first such analysis in patients with PAD. Eighteen individuals with PAD and eighteen healthy controls walked on a treadmill before and after the onset of claudication pain. Mean MTC and the …
