Relationally-Autonomous Reasons As A Predictor Of Collegiate Athletic Performance, Josef Max Katzman

Online Theses and Dissertations

The current proposed study examines a concept that has been looked at before but now using a new specific population. Previous research examined shows that reasons for motivation affect goal attainment and success. The current study is looking at how relational autonomous reasons for motivation play a role in goal attainment in athletes. Eastern Kentucky University athletes were administered a short questionnaire and their previous athletic performance was used as well. The two sets of data were then used to examine the relationship between the two variables. The results of the study showed a positive correlation between Relationally-Autonomous Reasons (RAR) …

Body Image Self-Discrepancies And Compulsive Exercise: Exploring The Role Of Approach And Avoidance Motivational Selves, Kristin A. Chandler

College of Graduate Studies: Theses & Dissertations

According to Brewer, Davis, Kalmbach, Kaptein, Katzman and Kirsch (1997), problematic exercise occurs in approximately 80% of anorexia nervosa patients and 55% of bulimia nervosa patients. Thus, a comprehensive understanding of unhealthy exercise is necessary for its assessment as well as eating disorder prevention and intervention. One term used to describe unhealthy exercise is compulsive exercise. Although compulsive exercise has been regarded as problematic in the development, treatment, and outcome of eating disorders, little research has investigated the risk factors for this behavior. Given the influence of body image disturbances on disordered eating and the relationship between compulsive exercise and …

Traditionally, aerobic training has been a central focus of exercise promotion for diabetes management. However, people with diabetes have much to gain from other forms of exercise. This article reviews the evidence and recommendations on resistance, balance, and flexibility training, as well as other, less traditional, forms of exercise such as yoga and Tai Chi.

Gait Intervention For Improvements In Human Top Speed Running, Michelle Buechner

Graduate Student Theses, Dissertations, & Professional Papers

Between individuals faster sprinting speeds are achieved by applying greater stance average forces against the running surface. Recent evidence further indicates that elite level performers also strike the ground with leg kinematics that differ from those of non-elites and that these leg movements act to enhance the force transients occurring in the milliseconds following foot-ground impact. I investigated whether sprint performance could be enhanced through a short term gait intervention, consisting of 3 laboratory training sessions wherein subjects (n = 6) completed 5 high-speed runs on an instrumented force treadmill at 90% of their measured top sprint. The subjects received …

Four participants (62.3 ± 6.5 yrs, Hoehn & Yahr 2-4) performed 8 weeks of treadmill training 3 times per week. Weeks 1-4 included forward walking only, while weeks 5-8 included forward and multi-directional walking. Participants were tested every 4 weeks on 4 separate occasions. Outcome …

Intravascular Atp And The Regulation Of Blood Flow And Oxygen Delivery In Humans, Anne R. Crecelius, Brett S. Kirby, Frank A. Dinenno

Health and Sport Science Faculty Publications

Regulation of vascular tone is a complex response that integrates multiple signals which allow for blood flow and oxygen supply to appropriately match oxygen demand. Here, we discuss the potential role of intravascular ATP as a primary factor in these responses and propose that deficient ATP release may contribute to impairments in vascular control exhibited in aged and diseased populations.

Vigorous Exercise Effect On Cardiovascular Health, Aryeh Mahana

The Science Journal of the Lander College of Arts and Sciences

Many studies examine the effects of vigorous cardiovascular exercise on the heart. Intense exercise causes frequent muscle contractions in the heart and specific biomarkers that usually signify a myocardial infarction are released into the bloodstream. However, studies indicate that there might not be a correlation between the release of biomarkers and cardiac function. Another study shows that long term vigorous exercise negatively affects the heart by dramatically increasing the mass and volume of the right and left ventricles, thereby resulting in hypertrophy. The cardiac hypertrophy is still evident even after the subjects have stopped exercising. Cardiac hypertrophy results in myocardial …

Health and Nutritional Sciences Faculty Publications

Background: The purpose of this study was to determine the prevalence of individuals who experienced exercise-induced adverse cardiometabolic response (ACR), following an evidence-based, individualized, community exercise program.
Methods: Prevalence of ACR was retrospectively analyzed in 332 adults (190 women, 142 men) before and after a 14-week supervised community exercise program. ACR included an exercise training-induced increase in systolic blood pressure of $10 mmHg, increase in plasma triglycerides (TG) of .37.0 mg/dL ($0.42 mmol/L), or decrease in high-density lipoprotein cholesterol (HDL-C) of .4.0 mg/dL (0.12 mmol/L). A second category of ACR was also defined – this was ACR that resulted …

Acute Effects Of Dynamic Stretching On Flexibility And Agonist-Antagonist Muscle Activity, Lance T. Beisley

EWU Masters Thesis Collection

"Flexibility is an important determinant of health and important in sport performance. ADS and SPST are the methods most often used in training flexibility for sport. Although ADS appears to dominate SPST in measures of power and agility, the mechanisms are unclear. The purpose of this study was to delineate the effects of ADS on AROM and agonist-antagonist mean and peak EMG. The ADS protocol involved three sets of ten repetitions of leg kicks while in the supine position with the pelvis and contralateral limb fixed in extension. Participants moved the leg at the hip in a kicking motion to …

Effect Of Load Carriage On Tactical Performance, Justin M. Thomas

Theses and Dissertations--Kinesiology and Health Promotion

Special Weapons and Tactics (SWAT) operators are specially trained personnel that are required to carry equipment to perform high risk tasks. Given the need to carry this equipment, it is important to understand the potentially deleterious effect that the additional load may have on tactical performance. Furthermore, it is important to identify physical fitness characteristics that are associated with the potential decrement in performance. Therefore, the purpose of this study was to evaluate the effect of load carriage on tactical performance and identify fitness characteristics associated with any decrement in performance. Twelve male operators performed a simulated tactical test (STT) …

The Effect Of Fluid Periodization On Athletic Performance Outcomes In American Football Players, Christopher W. Morris

Theses and Dissertations--Kinesiology and Health Promotion

For decades strength and conditioning professionals have been seeking optimal training volumes and intensities to yield maximum performance outcomes without the onset of injury. Unfortunately, current studies apply experimental training techniques without considering the individuals’ response to the imposed training load. Due to the vast genetic variability and extraneous environmental factors that affect one’s ability to recover, results from such studies are controversial and inconclusive. Athlete monitoring systems offer an objective assessment that is purported to evaluate an individual’s physiological readiness to adapt to an overload stimulus and thus allow for daily manipulations in training loads (i.e., fluid periodization). However, …

The Effects Of Spinal Manipulative Therapy On Isokinetic Strength And Postactivation Potentiation, Grant D. Sanders

Theses and Dissertations--Kinesiology and Health Promotion

Spinal manipulative therapy (SMT) is a therapeutic procedure employed by various healthcare practitioners for alleviating acute and chronic musculoskeletal complaints. This form of treatment is also delivered to enhance the performance and augment the rehabilitation of athletes. However, despite research findings alleging the strength-modulating effects of SMT alongside numerous professional athletes’ positive anecdotal claims concerning its results, the physiological processes to explain its effects remain largely unexplained. Therefore, the purpose of this work was to investigate the effects of SMT in a college-aged sample population with two experiments.

The first study examined the effect of SMT targeting the lumbosacral region …
