Fueling Performance: Determining The Efficacy Of Low-Carbohydrate Diet Models For Athletic Populations, Chelsea Jackle

Honors Theses

Advocates of low-carbohydrate (LC) diets assert that these diets help lessen dependence on sugar while aiding in the metabolism of fat tissue. Additionally, it is believed that lipolysis helps dieters feel more energetic, lose weight, and improve physical performance. For these reasons, many athletes and active people are drawn to diets such as the Atkins Diet, the South Beach Diet, the Paleo Diet, and the Zone Diet. According to current evidence, excessive weight loss, ketosis, reduced glycogen availability, dehydration, and increased stress hormone levels make LC diets that severely limit carbohydrates disadvantageous for athletes. Although LC diets are widely followed, …

Sex Differences In Whole Body Gait Kinematics At Preferred Speeds, Dustin A. Bruening, R. Frimenko, C. Goodyear, A. Fullenkamp

Faculty Publications

Studies on human perception have identified pelvis and torso motion as key discriminators between male and female gaits. However, while most observers would advocate that men and women walk differently, consistent findings and explanations of sex differences in gait kinematics across modern empirical studies are rare. In the present study we evaluated sex differences in whole body gait kinematics from a large sample of subjects (55 men, 36 women) walking at self selected speeds. We analyzed the data through comparisons of discrete metrics and whole curve analyses. Results showed that in the frontal plane, women walked with greater pelvic obliquity …

Faculty Publications

The relationship between dairy consumption and insulin resistance was ascertained in 272 middle-aged, nondiabetic women using a cross-sectional design. Participants kept 7-day, weighed food records to report their diets, including dairy intake. Insulin resistance was assessed using the homeostatic model assessment (HOMA). The Bod Pod was used to measure body fat percentage, and accelerometry for 7 days was used to objectively index physical activity. Regression analysis was used to determine the extent to which mean HOMA levels differed across low, moderate, and high dairy intake categories. Results showed that women in the highest quartile of dairy consumption had significantly greater …

Progressive Resistance Exercise With Eccentric Loading For The Management Of Knee Osteoarthritis., Haniel J. Hernandez, Valerie Mcintosh, Azadeh Leland, Michael O. Harris-Love

Exercise and Nutrition Sciences Faculty Publications

INTRODUCTION: The patient was a 58-year-old African-American male with radiographic evidence of bilateral knee osteoarthritis (OA). He participated in a standardized 12-week eccentric strengthening program within a Veterans Affairs (VA) medical center.

BACKGROUND: The use of an eccentric training paradigm may prove to be beneficial for older adults with knee OA since eccentric muscle actions are involved in the energy absorption at the knee joint during gait and controlled movement during stair descent. Furthermore, in comparison to standard muscle actions, eccentric muscle actions result in higher torque generation and a lower rate of oxygen consumption at a given level of …

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 …
