The Mediation Of Perfectionism And Rumination On Mindfulness And Burnout In Collegiate Athletes, Nicholas S. Mcmillen

College of Graduate Studies: Theses & Dissertations

Several positive and negative sport-related experiences can occur throughout an athlete’s career, which can affect the continuation or termination of said career. Although research has associated sport participation with positive outcomes (e.g., increases in motivation, autonomy), there are also negative sport-related outcomes such as burnout (Akhrem & Gazdowska, 2016; Garcia, 2015). Specifically, burnout has been identified as a multidimensional construct that includes three dimensions. Furthermore, mindfulness has been studied to minimize the risk of experiencing burnout (Kabat-Zinn, 2003). While several studies have examined mediators between mindfulness and burnout, there has been a dearth of research on perfectionism and rumination as …

The Effect Of Asymmetry On Pregnancy-Related Pain In The Postpartum Period, Krista G. Meder

Graduate Theses, Dissertations, and Problem Reports (ETD)

Nearly 50% of women experience back pain and other lower extremity pain during pregnancy, with many reporting lasting pain postpartum. Pregnant women experience changes to their pelvis and lower extremities that do not always return to pre-pregnancy baseline. Not much is known of the lingering effects of pregnancy related asymmetry and its relationship to pain. Therefore, the purpose of this study was to assess asymmetries of the pelvis and lower extremities to determine whether malalignment is related to areas of pain at the low back, hip, thigh, knee, leg, and foot/ankle. Methods: Seventeen postpartum women and seven nulliparous controls were …

Sprint Interval Training: Assessing Effectiveness And Adherence In A Real-World Setting, Gregory Howe

Theses and Dissertations (Comprehensive)

Introduction: Perceived lack of time is an oft-cited reason for not engaging in physical activity. One proposed solution is high-intensity interval training (HIIT), or a more intense version known as sprint interval training (SIT), which involves repeated “all-out” efforts interspersed with short recovery periods. Although convincing evidence demonstrates the efficacy of SIT on cardiorespiratory fitness and other health factors, whether individuals will independently perform and benefit from this type of exercise outside the supervised lab setting is unknown. Purpose: To compare the effectiveness and adherence of performing running SIT and moderate-intensity continuous training (MICT) protocols in a real-world setting. Methods: …

Influence Of Gluteus Medius Strength On Interlimb Asymmetry In Female Recreational Runners., Morgan Meyer, Olivia Moody, Kathryn Harrison, Gregory Crosswell, Bhushan Thakkar

UROP Posters

PURPOSE: Running-related injuries are most often single-sided and are partially attributed to lower limb movement and loading asymmetries.¹ Gluteus Medius (GM) plays a significant role in lower limb alignment, especially in the frontal and transverse planes by its influence on the pelvis and the femur.² Female runners are more prone to GM weakness which has been proposed to be a risk factor for overuse injuries.³ These strength deficits contribute to abnormal lower limb kinematics and kinetics during dynamic tasks like running and jumping.⁴ These changes include an increase in peak hip adduction angle (HA), hip internal …

The Effects Of Acute Exercise And Learning Strategy Implementation On Episodic Memory Performance, Faith A. Harris

Honors Theses

Over the years, a growing body of research has shown that exercise has beneficial impacts on various types of memory function. However, most of these studies have focused on children or older adults, with less research conducted among young adults, despite research demonstrating that memory function may start to decline in early adulthood. This thesis provides background information regarding the effects of exercise on memory function, as well as different learning-based strategies to help facilitate learning and memory retention. Furthermore, the research I completed for this thesis specifically evaluated the experimental effects of acute exercise, a specific learning strategy (3-R …

The Effects Of Footwear On Stride Length In Adolescent Baseball Pitchers, Alexandra Adderholt

Honors Theses

The baseball pitch is considered one of the most dynamic athletic motions. Due to its complexity, multiple variables are taken into consideration for risk of injury. Previous studies have investigated variables that influence factors of a baseball pitch such as fatigue and stride length; however, footwear has not been considered. This study's objective was to examine whether or not baseball footwear on different surface inclinations altered stride length. Eleven adolescent pitchers (Age: 13.18 ± 1.72 yrs.; Height: 179.01 ± 15.72 cm.; Mass: 61.00 ± 14.66 kg) participated in this study throwing in four shoe-surface conditions: flat ground (FG) x molded …

The Sidewalk Problem: An Examination Of The Avoidance Behaviours Employed During A Head-On Collision Course With An Approaching Person, Lana M. Pfaff

Theses and Dissertations (Comprehensive)

Individuals use visual information in order to guide their avoidance behaviours. More specifically, individuals may directly perceive the time prior to colliding with an approaching obstacle (i.e., time to contact, TTC) in order to determine when to avoid. However, if the path of the approaching obstacle is highly predictable, individuals do not use a consistent TTC (Cinelli & Patla, 2007). Additionally, individuals use body- and action-scaled information to control their movements (Fajen, 2013). These avoidance behaviours differ when avoiding a human obstacle compared to an inanimate object (Hackney, Cinelli, & Frank, 2015; Knowles, Kreuser, Haas, Hyde, & Schuchart, 1976). As …

Differences In Perceptions Of Aperture Crossing During A Virtual Reality Choice Reaction Task Between Non-Athletes And Varsity Athletes, Jaime Mitchell

Theses and Dissertations (Comprehensive)

Background: Vision will guide the actions and behaviors that allow us to circumvent environmental obstacles. When passing through a gap, individuals will consistently elicit a shoulder rotation (SR) if the gap is 1.4 times their shoulder width (SW) or narrower, with this behaviour being produced under various environmental conditions. Although a few studies have investigated perceptual predictions regarding gap passage, the effect of physical activity and the differences between trained and untrained athlete’s behaviours has not been examined. This study investigated the perceptual judgements of non-athletes and varsity athletes regarding the action they would utilize to pass through a dynamically …

The Role Of Circulating Mirnas As Clinical Biomarkers Of Insulin Sensitivity And Exercise Adaptation In Young Offpsring Of Type 2 Diabetes Patients, Cesar Arturo Meza

Open Access Theses & Dissertations

Background: A family history of Type 2 Diabetes (FH) is considered a risk factor for development of type 2 diabetes (T2D). Exercise training is an effective strategy to improve insulin resistance. Recently, micro-RNAs (miRNAs) have emerged as mediators of various intracellular processes, including insulin signaling, and may act as signaling molecules when released into circulation. The miRNAs -29a, -133a and -155 have been implicated in the regulation of insulin sensitivity, however their roles in exercise training-induced improvements in insulin sensitivity are yet to be elucidated. The purpose of this study was to determine whether circulating miRNA-29a, miRNA-29b, miRNA-29c, miRNA-133a, miRNA-133b …
