The Effects Of 8 Weeks Of Low Dose Supplementation Of Creatine And Sodium Bicarbonate On Exercise Performance, Amanda Jessica Morris

Master's Theses

Short-term (3-7 days), high doses of creatine (20g/d) and/or sodium bicarbonate (0.5g/kg body weight) supplementation increase exercise performance during short term high intensity activities; however, it remains unclear whether long-term, low doses of these supplements have a positive impact on exercise performance. The purpose of this study was to determine the effects of long-term (8 weeks), low dose creatine supplementation on exercise performance, and whether combining creatine and sodium bicarbonate supplementation has an additive effect. Sixty-three healthy, habitually active, adults (28 M, 35 W; 22+2 years; 23+ 3 BMI) were randomly assigned by sex to one of three supplement groups: …

Formulation To Predict Lower Limb Muscle Forces During Gait, Gil Serrancolí, Jonathan P. Walter, Allison Kinney, A. Barjau, Benjamin J. Fregly, Josep M. Font-Llagunes

Mechanical and Aerospace Engineering Faculty Publications

The human body has more muscles than Degrees of Freedom (DoF), and that leads to indeterminacy in the muscle force calculation. This study proposes the formulation of an optimization problem to estimate the lower-limb muscle forces during a gait cycle of a patient wearing an instrumented knee prosthesis. The originality of that formulation consists of simulating muscle excitations in a physiological way while muscle parameters are calibrated. Two approaches have been considered. In Approach A, measured contact forces are applied to the model and all inverse dynamics loads are matched in order to get a physiological calibration of muscle parameters. …

An Autoethnographical Tapestry Of Feminist Reflection On My Journey Of A Fitness Model Physique, Stephanie A. Paplinskie

Electronic Thesis and Dissertation Repository

Weight training and fitness competitions are increasingly popular activities for many women seeking an aesthetically fit body. This thesis entails a critical reflection of the various factors surrounding my personal decision to partake in body sculpting, examining how these factors parallel the experience of other women in the fitness industry. Using a feminist theoretical framework and autoethnography, a history of feminist theory is incorporated to demonstrate some of the various perspectives surrounding women bodies. Two challenges for women are discussed in this paper: i) the fear of fat, and how it is connected to a woman’s initial decision to attend …

The Effect Of Exercise On Cravings And Ad Libitum Smoking Following Concurrent Stressors, Angela J. Fong

Electronic Thesis and Dissertation Repository

Quitting smoking itself is a stressor; it is likely that other stressors occur concurrently and deplete self-regulatory resources. Failure to cope leads to smoking relapse. Exercise has been shown to attenuate cravings and withdrawal symptoms in previous research and has yet to be examined following concurrent stressors. This study examined the effect of an acute bout of moderate intensity exercise on psychological withdrawal symptoms (PWS), cravings and ad lib smoking after concurrent stressors (i.e., temporary abstinence and depletion). Twenty-five smokers were randomized into exercise or passive conditions. Results showed PWS were significantly exacerbated after temporary abstinence and again after depletion …

The Philosophy Of ‘Playing’ Games: A Lusory Introspection Of The Sincere Player And The Meaning Of Play Amidst The Moral Morass Of Contemporary Sport, Justin M. Rhoden

Electronic Thesis and Dissertation Repository

Play is a fundamental experience embedded within human culture. We all play in some perceptible manner that provides our lives with meaning we don’t ordinarily feel from other pursuits that are means-ended. Sport philosophers have depended upon the seminal theories of Huizinga and Caillois to shape their constraints on the play world. Huizinga’s and Caillois’ definition both use formal analysis to protect the play sphere however, their theories fail in providing justifiable reason to protect the play sphere and the meaning it has. I propose that understanding play from the perspective of existentialism provides a better way to understand its …

Understanding The Volunteer Youth Coaching Environment: A Psychological Contract Perspective, Alanna Harman

Electronic Thesis and Dissertation Repository

The purpose of this dissertation was to explore the volunteer coaching environment using psychological contract theory. Psychological contract posits that volunteers and their organization have implicit and explicit expectations of each other, and the breach and fulfillment of these expectations impact volunteers’ attitude and intended behaviour.

Study 1 explored the content of volunteer coaches’ psychological contract, and influences to the development of it. Interviews with 22 coaches of team sports, representing different demographic factors were included. The results revealed that volunteer coaches possess both transactional and relational expectations. Variation was found by coaching tenure and level of play. Sources external …

"Every Day, We Have The Opportunity To Make A Difference": Ncaa Division I Female Head Coaches' Experiences Of Care, Susannah Kaye Knust

Doctoral Dissertations

According to sport psychology literature, care is an important part of the coach-athlete relationship (e.g., Jowett & Poczwardowski, 2007; LaVoi, 2004; Poczwardowski, 1997; Wylleman, 2000). However, a systematic study of “exemplar” caring coaches is lacking. Therefore, the purpose of this study was to interview 12 National Collegiate Athletic Association (NCAA) Division I head female coaches of female teams who were identified by others as “exemplar” carers. A semi-structured interview guide was developed using a modified version of Gilligan and colleagues’ (1989) Listening Guide. An adaptation of Hatch’s (2002) political analysis was used to identify major themes found in the transcribed …

Exercise Participation During Weight Loss On A High Protein – Low Carbohydrate Diet Plan In Females Aged 15-25 Years, Margaret Mobley-Meulman

Electronic Theses and Dissertations

Weight gain due to poor diet and lack of exercise is responsible for over 300,000 deaths each year (U.S. Department of Health and Human Services, 2010). Obese adults have an increased risk for serious health conditions including high blood pressure and cholesterol, type 2 diabetes, coronary heart disease, stroke, gallbladder disease, osteoarthritis, sleep apnea, respiratory problems, and certain cancers (National Cancer Institute, 2012). Participation in exercise can help control weight, strengthen muscles and bones, and reduce the incidence of cardiac events, stroke, hypertension, type 2 diabetes, colon and breast cancers, osteoporotic fractures, gallbladder disease, obesity, depression, anxiety, and delay mortality …

Design And Development Of A Stair Ascension Assistive Device For Transfemoral Amputees, Casey Michael Barbarino

Master's Theses

Transfemoral amputees around the world experience increased difficulty in climbing stairs due to lack of muscle, balance, and other factors. The loss of a lower limb greatly diminishes the amount of natural force generation provided that is necessary to propel oneself up stairs. This study investigated possible solutions to the problem of stair ascension for transfemoral amputees by the means of designing and developing an externally attachable device to a prosthesis. The number of amputations from military service has greatly increased since 2008, which shows there is a clear need for assistive devices (Wenke, Krueger, & Ficke, 2012). With the …

Associations Between Heart Rate Variability And Metabolic Syndrome Risk Factors, Melanie I. Stuckey

Electronic Thesis and Dissertation Repository

Metabolic syndrome (MetS) is a clustering of risk factors for cardiovascular disease (CVD) and type 2 diabetes (T2D) – two major causes of morbidity and mortality worldwide. Heart rate variability (HRV) is a non-invasive measure of cardiac autonomic regulation that predicts mortality and morbidity. Additionally, HRV is reduced in CVD, T2D and MetS. As such, HRV has potential to be a novel cardiometabolic risk factor to be included in clinical risk assessment. Therefore, the purpose of this thesis was to examine the relationships between MetS and HRV. A systematic review of cross-sectional studies examining relationships between HRV and MetS was …

Aasp-Certified Consultants’ Experiences Of Spirituality Within Sport Psychology Consultation, Trevor Jonas Egli

Doctoral Dissertations

According to Watson and Nesti (2005), the scholarly investigation of spirituality within sport psychology is lacking. Recently, within cultural sport psychology (Schinke & Hanrahan, 2009), a discussion of spirituality has been initiated; however, it has not received the same amount of attention as other aspects of culture that impact sport performance and mental well-being (Butryn, 2002, 2010; Duda & Allison, 1990; Kontos & Breland-Noble, 2002; Krane, Waldron, Kauer & Semerjian, 2010; McGannon & Busanich, 2010). Therefore, the purpose of this study was to understand how AASP-certified (CC-AASP) consultants understand spirituality. Nine AASP-certified (CC-AASP) consultants who have encountered spirituality in their …

Investigations Toward Tunability Of Mechanical, Thermal, And Impact Properties Of Thiol-Ene Networks For Novel High Energy Absorbing Materials, Olivia Devon Mcnair

Dissertations

The UV polymerization of thiols with electron rich alkenes is a highly resourceful reaction that has been utilized by scientists within various disciplines to produce an even more versatile display of applications. This dissertation focuses on a newer application, thiol-ene network (TEN) materials for energy absorption devices. TEN networks display a host of positive polymer properties such as low stress, high optical clarity and uniformity, but they also suffer from unfavorable mechanical properties such as low toughness and elongation at break. The poor mechanical properties demonstrated by TENs prohibit them as choice materials for applications requiring thicker material forms, including …

An Investigation Of Preferred Versus Imposed Exercise, Personality Traits, And Motivation On An Exercise Dependent College Aged Sample 2013, Chelsea M. Norton

Master's Theses

The purpose of this study was to: (a) investigate personality traits and motivation among an exercise dependent sample by using and examining theoretically based assessment tools and (b) measure feeling states under different types of physical activity among those who were considered to be exercise dependent. Four hundred twenty-three college students (54.4% male, 45.6% female) who met the inclusion criteria completed the Exercise Dependence Scale-Revised (EDS-R; Symons Downs, Hausenblas, & Nigg, 2004), Exercise Addiction Inventory (EAI; Terry, Szabó, & Griffiths, 2004), Exercise Identity Scale (EIS; Anderson & Cychosz, 1994), Behavioral Regulations in Exercise Questionnaire-2 (BREQ-2; Markland & Tobin, 2004), and …

An Analysis Of Firearms Training Performance Among Active Law Enforcement Officers, John Thomasson

Graduate Theses and Dissertations

Firearms proficiency is an implicit expectation, held by the public of police officers, due to presumption that the required firearm training is an adequate preparation for a deadly force encounter. However, anecdotal evidence and available data on police shootings suggest that conventional, unrealistic training methods are wholly inadequate. To present stress into firearms training, some departments have opted for exercises such as physical exertion and shoot-house training as a substitute for realistic simulation of force-on-force confrontations.

To determine whether such exercises are comparable, an observation of performance and heart rate levels was conducted on a group of eight police officers, …

Robin Shook

Context: Relationships between socio-environmental factors and obesity are poorly understood due to a dearth of longitudinal population-level research. The objective of this analysis was to examine 45-year trends in time-use, household management (HM) and energy expenditure in women. Design and Participants: Using national time-use data from women 19–64 years of age, we quantified time allocation and household management energy expenditure (HMEE) from 1965 to 2010. HM was defined as the sum of time spent in food preparation, post-meal cleaning activities (e.g., dish-washing), clothing maintenance (e.g., laundry), and general housework. HMEE was calculated using body weights from national surveys and metabolic …

Role Of Satellite Cells In Long Term Fiber Type Shifts, Honglu Liu

Lewis Honors College Capstone Collection

Muscle fiber type shifts in respect to satellite cells, muscle stem cells, are not well understood currently. The Peterson Lab has generated a mouse model (PAX7-DTA) that ablates satellite cells to determine if these muscle stem cells contribute to mouse muscle fiber type changes over an eight week period. In the study, control and satellite-cell-ablated mouse groups were split into control and overload groups (via synergist ablation surgery) and placed under similar environmental conditions. Eight weeks post-experiment, muscles were dissected to obtain the plantaris muscles of animals from all groups. Muscle cross-sections obtained were immunohistochemically stained, imaged, quantified by fiber …

The Change Program: Methodology For Comparing Interactive Co-Active Coaching With A Prescriptive Lifestyle Treatment For Obesity, Don Morrow, Erin Pearson, Jennifer Irwin

Donald Morrow

Studies incorporating Motivational Interviewing via Co-Active life coaching (MI-via-CALC) have elicited positive results among obese adults; however there is a paucity of comprehensive MI-via-CALC-obesity research that includes sufficient statistical power and a validated comparison group. The purpose of this study was to compare two telephone-based interventions for obesity. University students were randomized to either a 12-week: (a) personalized MI-via-CALC program whereby a coach worked with participants to achieve goals; or (b) prescriptive education-based lifestyle treatment following the LEARN Program. This paper contains a detailed methodological account of the study with a view to informing the development of prospective coaching-based programs.
