Changes In Swim Performance And Perceived Stress And Recovery In Female Collegiate Swimmers Across A Competitive Season, Jacquelyn Zera, James Mcmillan, Barry Munkasy, A. Joyner, Stephen Rossi

Exercise Science and Sports Studies

Optimal sport performance involves balancing the accumulation of training stress with adequate recovery (Budgett, 2000; Hollander & Meyers, 1995). Continuous evaluation of an athlete's performance levels, stress levels, and recovery states during a competitive season is important in determining an athlete's readiness for competition. Limited examination of these three factors appears for collegiate athletes; thus this study's purpose was to examine effects of training load on psychological and performance variables among collegiate female athletes across a competitive season. Nineteen NCAA Division I female swimmers completed monthly testing including six tethered swim tests and seven Recovery-Stress Questionnaires (RESTQ-76), yielding mean force …

Church Pew Exercise Integrated With Conventional Physical Therapy Following Total Knee Arthroplasty (Tka): Case Report, Randell Gonzales, Jerome V. Danoff

Exercise and Nutrition Sciences Faculty Publications

Background and Purpose: Physical therapy treatment following Total knee Arthroplasty (TKA) consists of a combination of strengthening and range of motion exercises. The exercise technique, church pew exercise (CPE), has been proposed to enhance quadriceps facilitation and improve function. This is a technique that has the patient standing and rocking forward/back. The backward motion is arrested by engagement of the upper calf against a solid object, creating a sudden flexion torque at the knee and a sudden extension torque at the hip. The combination of CPE with standard physical therapy is claimed to provide better quadriceps control and faster walking …

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 …

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 …

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 …

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, …

Investigating The Effects Of Alternative Footwear On Balance, David S. May

Honors Theses

Falls are one of the leading causes of injuries and unintentional deaths in the United States, with 27,800 fatalities attributed to falls in 2012 (National Safety Council, 2014). With two thirds of our body mass located two thirds of our body height above the ground, humans require constant work from balance control systems to prevent these falls (Winter, 1995). Because shoes can alter somatosensory input from the mechanoreceptors on the bottom of the foot and affect these balance control systems (Menant et al, 2008), they must be taken into account when looking into the causes of falls. Traditional footwear designs …
