Neuromuscular Adaptations To Voluntary Contraction Following Postactivation Potentiation, Cameron B. Smith

Electronic Thesis and Dissertation Repository

Muscle contractile properties are history-dependent, and following a conditioning contraction, muscle tissue may be fatigued (slower, weaker) or potentiated (faster, stronger). Postactivation potentiation of evoked contractions, such as the electrically stimulated twitch, has been thoroughly studied. However, the effects of potentiation on voluntary contraction are not well understood, and prior study is largely equivocal.

The following studies propose to determine the effects of potentiation during 1) submaximal contractions at different muscle lengths 2) ballistic contractions following tetanic and voluntary conditioning, and 3) motor evoked potentials following tetanic and voluntary conditioning contractions. Evoked twitch potentiation was assessed with all of the …

A Philosophical Analysis Of Ethics Education In The Canadian National Coaching Certification Program For Rowing, Mark M. Williams

Electronic Thesis and Dissertation Repository

This dissertation applies a conception of rationality from the philosophy of science to the coaching education context. The purpose of this dissertation is to present an account of how the exercise of judgment by coaches facing ethical dilemmas can be rational. The discussion in this dissertation begins with a traditional account of rationality that has long been a staple of moral philosophy. Next, the influence of this model in the current Canadian rowing coach education program are highlighted, as are its limitations in providing a complete account of rational ethical-decision making in the coaching context. After establishing these limitations, an …

The Effect Of Attentional Focus Instructions On Golf Swing Performance In Recreational Golfers, Jeffrey D. Eggleston

Boise State University Theses and Dissertations

Previous research has addressed the effectiveness of attentional focus instructions in improving golf performance with a single training session. The purpose of the current study was to investigate the effect of external (EF) attentional focus instructions on recreational golfers’ performance over a distributed training period and extended retention interval. Performance was measured by club head velocity (CHV) and X-factor as both have been correlated with greater performance. The current study extends the work of An, Wulf, and Kim (2013), by increasing the training period and retention interval. It was hypothesized EF group would have greater CHV and X-factor measurements during …

"It Starts With Having A Conversation": Lesbian Student-Athletes' Experience Of U.S. Ncaa Division I Sport, Jamie Fynes

Masters Theses

According to Griffin (1998), the U.S. NCAA Division I sport environment is not very welcoming for lesbian student-athletes because of existing negative myths and stereotypes. In addition, the experiences of both current and former lesbian collegiate athletes is an underrepresented research topic. Therefore, the purpose of this study was to explore the experiences of 10 former U.S. NCAA Division I lesbian student-athletes using a semi-structured personal identity interview guide (Fisher, 1997) and Consensual Qualitative Research (CQR) (Hill, Thompson, & Williams, 1997). Five domains, 19 categories, and related core ideas were found in the transcribed interviews. In Domain I: Stereotypes and …

The Effects Of Apoe Knock Out On Skeletal Muscle Regeneration: A Look Into Markers Of Protein Synthesis And Satellite Cell Function, Joshua Eden Ragland

Graduate Theses and Dissertations

ApoE helps regulate serum cholesterol levels by adding in transport of cholesterol into the cells, as well as, to the liver. ApoE knockout mice (ApoE KO) present a model that demonstrates the effects of hypercholesterolemia. Damage to muscle stimulates a complex regenerative response. The effects of high cholesterol on this regenerative response are not known. PURPOSE: To determine if skeletal muscle regeneration is altered in apoE KO mice by measuring protein synthesis regulator IGF-1, Akt, mTOR, and p70S6K, cell cycle regulator cyclin D1, and myogenic regulatory factors myoD and myogenin. METHODS: Female C57/BL6 (WT) and apoE KO were assigned to …

Quantifying Cognitive Function In Concussed Athletes Before And After Acute Exercise Using A Choice Reaction Time Task, Stephanie A. Ramautar M.Sc., Michael E. Cinelli Ph.D.

Theses and Dissertations (Comprehensive)

Following a concussion, cognitive deficits have been shown to last longer than symptom resolution. Currently clinicians rely heavily on symptom emergence following the fundamental exercises of the return to play (RTP) protocol, which may leave athletes at risk of returning to play too early if cognitive deficits have not been detected. The purpose of this study was to assess the effects of exercise on choice reaction time (CRT) both at rest and following an acute exercise in 3 populations: non-concussed (NC), recently concussed (RC), and post-concussion syndrome (PCS) individuals. A CRT task in the form of an iPad application measured …

The Lived Experiences Of Adult Siblings Of Individuals With Asd, Brianne Redquest

Theses and Dissertations (Comprehensive)

Autism Spectrum Disorders (ASD) are the most prevalent neurological and severe developmental disorder affecting 1 in 88 Canadians, reflecting a 78% increase over the last 6 years (Autism Speaks Canada, 2013). ASD is a lifelong disorder which requires a tremendous amount of support and caregiving from family members. As a result, siblings may have unique experiences associated with having a sibling with ASD. As such, the purpose of this study was to examine the lived experiences of adult siblings of individuals with ASD.

An Exploratory Examination Of Families Engaged In An Adventure Running Kids Program, Heather Isnor

Theses and Dissertations (Comprehensive)

Academics and practitioners have only just begun to delve into the health benefits of outdoor activities in the last few years. In general, the forested settings of these activities have been documented to decrease stress levels, increase recovery rates from disease, and lessen the symptoms of mental illnesses (Kuo & Faber Taylor, 2004). It is believed that the natural environment acts as a setting where humans can engage in physical activity, aesthetic experiences, and social interactions that, in turn, release stress and lead to improved well-being (Bird, 2012). Currently, however, children are experiencing limited exposure to nature and which has …

Antecedents Of Athletes’ Achievement Goal Orientations, Matthew Lachman

Electronic Theses and Dissertations

Theorized by Nicholls (1984), achievement goal theory describes the interaction of one’s perceived ability and two goal orientations, known as “task” and “ego,” that an athlete employs when setting goals. These goal orientations are what athletes employ when playing their sport. The result of this interaction is an athlete’s achievement behavior. Previous research has examined this theory extensively (Newton & Duda, 1999; Chin, Khoo, & Low, 2012; Smoll, Smith, & Cumming, 2007; White & Zellner, 1996). However, few studies have solely looked at factors that predict one’s achievement goal orientations. The purpose of this study is to address which demographic …
