Are There Bad Wins And Good Losses? Outcome Effects In Sport, Richard Erik Inglis

Masters Theses, 2010-2019

Abstract

Outcomes have been shown to distort feeling states, performance evaluations, and subsequent performances. This retrospective distortion represents an outcome bias, a phenomenon that has been studied extensively in a wide array of disciplines and domains. However, despite their importance, the effects of outcomes have received little attention in the sport corpus. In an attempt to remedy this oversight, 60 participants with basketball experience were recruited to take part in a free throw shooting competition. Participants completed two rounds of 20 free throws. Following their first round, participants were randomly assigned to either a negative outcome (lose by one shot) …

Development Of The Running Identity Scale, Matthew Philip Bejar

Doctoral Dissertations

The construct of running identity has been explored in both the sport psychology (e.g., Busanich, McGannon, & Schinke, 2012) and sport sociology literature (e.g., Allen-Collinson & Hockey, 2007). In comparison to other athletes, runners are typically more susceptible to exercise addiction (Coen & Ogles, 1993; Sachs, 1981), eating disorders (Wheeler, Wall, Belcastro, Conger, & Cumming, 1986), and preoccupation with leanness (Allen-Collinson & Hockey, 2007; Busanich et al., 2015). While instruments such as the Athletic Identity Measurement Scale (AIMS; Brewer, Van Raalte, & Linder, 1993) and the Public-Private Athletic Identity Scale (PPAIS; Webb & Nasco, 2006) measure athletic identity, there are …

The Effects Of The Fifa 11+ Warm Up Program In Female Collegiate Soccer Athletes, Stacey O’Neill

Graduate Theses

As of 2010 there were over 265 million registered soccer athletes worldwide, and in particular, the number of women players were rapidly increasing (Soligard, et al., (2010). Consequently, playing soccer accounts for approximately one quarter of all injuries in sport, and due to its nature of jumping, pivoting and cross-cutting, the majority of these are non-contact, lower extremity injuries. Therefore, playing soccer entails a substantial amount of injury risk for its participants. The purpose of this study was to investigate the effects of the FIFA 11+ Warm Up Program in collegiate female soccer athletes.

Examining The Motivations And Benefits Of Student-Athletes Performing Community Service., Matthew Ryan Huml

Electronic Theses and Dissertations

With over 460,000 active student-athletes (NCAA, n.d.), the student sub-population is large enough to investigate potential options for institutions to increase their academic achievement. Additionally, participating in academic-related activities is especially important because of concerns about student-athletes spending more than the 20 hours per week the NCAA allows for working on their sport (Wolverton, 2008). Studies frequently highlight a lack of effort by student-athletes to adjust to academic opportunities and expectations within higher education (Adler & Adler, 1991; Lally & Kerr, 2005; Levine, Etchison, & Oppenheimer, 2014; Miller & Kerr, 2003). To combat this adjustment to higher education, community service …

The Effect Of Descriptive Norms On Resistance Exercise Self-Efficacy In College-Aged Females 2016, Justin Kompf

Master's Theses

Resistance training is a form of physical activity that provides substantial health benefits. Despite these widespread benefits, participation in resistance training is considerably low, particularly among females. To engage in a skill-related activity such as resistance training, individuals need to have confidence in their abilities. Self-efficacy is a cognitive construct that is used to describe situation-specific self-confidence. Descriptive norms are a type of social norm that describes the behavior of others. Descriptive norms have been useful in positively changing health related behaviors. The exact mechanism of how descriptive norms alter behavior is unknown. However, it has been show in research …

Energy Management Mechanisms Employed At The Human-Material Interface Of Traditional And Minimalist Shod Running, Nadine M. Lippa

Dissertations

From recreational to elite athletes, greater than 50% of runners sustain overuse injuries each year, prompting substantial research efforts to identify causes of—and solutions to—the high injury rate. Different shoe types and material property degradation have been related to injury. Two popular footwear types are traditional shoes with thick graded soles and minimalist running footwear with thinner foam and/or non-graded soles. Notwithstanding 45 years of significant modifications to shoe design features, gained knowledge in kinesiology, and advanced technologies in polymer science, runner injury rates have not decreased and EVA foam has remained the primary running shoe midsole material since the …

Relationship Of Force Variables To Vertical Jumps Performance, Hugo A. De Paula Santana

Electronic Theses and Dissertations

The isometric mid-thigh pull (IMTP) has been cited often in the scientific literature; however, there is still a lack of agreement as to the ideal body position used during this test, and how body position impacts the relationship between IMTP performance and dynamic performance. Thus, one aim of this dissertation was to compare two different IMTP positions and correlate the kinetic outputs from each position to vertical jump (VJ) performance. Another purpose of this dissertation was analyze which method of data normalization for IMTP force variables best correlates to squat jump (SJ) and countermovement jump (CMJ) performance.

Identifying And Reducing Risk Of The Female Athlete Triad In Division I Athletes, Jennifer Day

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Physically active females, or female athletes, are at risk for the condition known as the female athlete triad (Triad). The Triad is made up of three components that are distinctly separate, but intertwined: consuming inadequate energy for how much they are exercising, poor bone health, and problems with their menstrual periods. When female athletes don’t consume enough energy for how much they exercise, there can be hormonal imbalances, causing the body to conserve energy from some important functions including menstruation, and increased bone turnover resulting in a higher risk of stress fractures and early osteoporosis. Female athletes at risk for …

Senior Year Experience Student Projects

We had the privilege to give back to our community in the form of manual labor. The Westerville Naturals baseball team needed a hand moving gravel in order to store a shed behind their field. The team provided a gator to transport the gravel from the parking lot to the field. The objective was to scoop shovels full of gravel into the back of the gator. We took multiple trips to load the five tons of gravel and transport it to the new location. Once moved, the sheds needed a facelift so it was decided to paint the sheds. We …

Gait Changes During Exhaustive Running, Nathaniel I. Smith

Masters Theses

Runners adopt altered gait patterns as they fatigue which may increase energy expenditure and susceptibility to certain overuse injuries. Previous investigations have described changes in muscle performance and kinematic gait variables resulting from running fatigue. The purpose of this investigation was to characterize changes in joint moment patterns that develop as runners fatigue in order to better understand the kinetic bases for kinematic fatigue effects. It was hypothesized that when fatigued, runners would demonstrate increases in stance time, peak stance phase knee flexion angle, peak knee extension moment, peak swing phase hip flexion moment, and hip extension and plantarflexion angular …

Effects Of Isolated Core Stability Training On Standing Static Postural Control, Recovery Of Standing Postural Control And Kicking Velocity In Soccer Athletes, Ali El-Kerdi

Seton Hall University Dissertations and Theses (ETDs)

BACKGROUND: About 1/3 of injuries are non-contact in nature and half of these involve the LE’s. There are numerous anatomical and physiological mechanisms and systems involved in stabilizing the trunk for movement of the lower extremities. The ability of the trunk to maintain the position and motion of the trunk over the pelvis and LE’s is predominantly accomplished via quick postural responses to internal and external forces. These pre-programed postural responses are integrated within the neuromuscular system. It is theorized that poor core stability is a result of a failure in the neuromuscular system to support the trunk and pelvis …

Mathematical Modeling Of Heart Rate Deflection Point In Relation To Respiratory Compensation And Treadmill Running Performance, Kayla Baker

Electronic Theses and Dissertations

Heart rate deflection point (HRDP), identified as the second breakpoint in the "intensity / heart rate" relationship, is indicative of the anaerobic threshold (AT). This point can be determined via bi-segmental linear regression (2SEG) or through use of the maximal distance model (D-max); however, the relationship between these methods has yet to be investigated 2. Purpose: To compare the use of 2SEG and D-max methods to determine HRDP and to examine the relationship between these values with a metabolic threshold, respiratory compensation point (RCP), as well as running performance [5,000 meter treadmill time trial (5Ktime)]. Methods: Nineteen recreationally active men …

The Reproducibility And Validity Of Using The Dmax Method To Predict Physical Working Capacity At Fatigue Threshold, Joshua Riffe

Electronic Theses and Dissertations

Although the original (ORG) physical working capacity at fatigue threshold (PWCFT) assessment has demonstrated strong reliability and sensitivity to training and/or nutritional interventions, limitations may exist regarding the method of PWCFT estimation. However, a relatively new mathematical method, called Dmax, has been shown to be objective and reliable when estimating metabolic and neuromuscular fatigue thresholds. To date, however, no study has examined whether the Dmax method for estimating the work rate at PWCFT is similar to the ORG method. PURPOSE: The purpose of this study is to evaluate the reliability and validity of the Dmax-EMG method for estimating and tracking …
