The Comparison Of Using The Preferred Or Non-Preferred Wrist When Measuring Physical Activity In College Students, Bryce Daniels

Graduate Theses and Dissertations

Introduction. People who participate in regular physical activity have a decreased risk of chronic diseases and premature death. A dramatic decrease of physical activity occurs from adolescence to young adulthood. With important implications to health, physical activity is an important behavior to measure. However, inconsistencies exist on how to measure physical activity. When using accelerometers, differences between the preferred or non-preferred wrist may result in different estimates of physical activity. Purpose. The purpose of this study was to compare the preferred and non-preferred wrist accelerometry measured physical activity using commonly used research accelerometers during structured daily college activities (Actigraph GT3x-bt …

Disordered Eating Risk And Body Image Dissatisfaction Of Division I Male And Female Cheerleaders, Christopher Blaszka

Graduate Theses and Dissertations

The sport of cheerleading is growing both in the high school and college setting, however there is little research on cheerleaders specifically, both sideline and competitive. It is clear that while this sport does not benefit from being affiliated with the NCAA, the athletes are still at large risk for disordered eating and eating disorders, and are in need of more accurate screening and prevention methods. With the lack of cheerleading studies in general, there is an even larger scarcity of studies that focus on males in cheerleading. The current study aims to fill the gap in the research regarding …

Does Hydration Impact Memory: A Systematic Review, Kelsey Ellis-Lepard

Health, Human Performance and Recreation Undergraduate Honors Theses

With 60% of the adult human body composed of water it makes sense that maintaining proper hydration levels is important to survival as well as living a healthy life. Water has many roles throughout the human body: thermoregulation, being a carrier, being a lubricant, and acting as a reaction medium. As a carrier, water is responsible for allowing exchanges between cells, interstitial fluid and capillaries. In addition, water regulates the blood volume and allows blood circulation. Since water is responsible for these tasks, many systems in the body as well as the brain are reliant upon proper hydration levels to …

Likewise, there are currently no studies exploring athletic retirement from the perspective of student-athlete support or development services, a section of athletic departments that provides programming for the success of their student-athletes. Purpose: The purpose of this study was to explore the implications of athletic retirement from the perspective of directors and/or associate directors of student-athlete support or development services of …

Type 2 Diabetes Impairs The Ability Of Skeletal Muscle Pericytes To Augment Postischemic Neovascularization In Db/Db Mice, Katherine L. Hayes, Louis M. Messina, Lawrence M. Schwartz, Jinglian Yan, Amy S. Burnside, Sarah Witkowski

Exercise and Sport Studies: Faculty Publications

Peripheral artery disease is an atherosclerotic occlusive disease that causes limb ischemia and has few effective noninterventional treatments. Stem cell therapy is promising, but concomitant diabetes may limit its effectiveness. We evaluated the therapeutic potential of skeletal muscle pericytes to augment postischemic neovascularization in wild-type and type 2 diabetic (T2DM) mice. Wild-type C57BL/6J and leptin receptor spontaneous mutation db/db T2DM mice underwent unilateral femoral artery excision to induce limb ischemia. Twenty-four hours after ischemia induction, CD45-CD34-CD146+ skeletal muscle pericytes or vehicle controls were transplanted into ischemic hindlimb muscles. At postoperative day 28, pericyte transplantation augmented blood flow recovery in wild-type …

Influence Of Baseline Muscle Strength And Size Measures On Training Adaptations In Resistance-Trained Men, Gerald T. Mangine, Adam M. Gonzalez, Jeremy R. Townsend, Adam J. Wells

Faculty Articles

The influence of baseline strength or muscle size on adaptations to training is not well-understood. Comparisons between novice and advanced lifters, and between stronger and weaker experienced-lifters, have produced conflicting results. This study examined the effect of baseline muscle strength and size on subsequent adaptations in resistance-trained individuals following a traditional high-volume, short-rest resistance training protocol. Fourteen resistance-trained men (24.0±2.7 y; 90.1±11.7 kg; 169.9±29.0 cm) completed pre-training (PRE) ultrasound measurements of muscle cross-sectional area (CSA) in the rectus femoris (RF), vastus lateralis (VL), pectoralis major, and triceps brachii (TRI) prior to strength assessments (e.g., one-repetition maximum strength bench press and …

Impact Of Prolonged Sitting On Central Hemodynamics: Role Of Intermittent Pneumatic Compression Therapy, Anna Kayleigh Downey

Master's Theses

Prolonged sitting (3-6 hours) negatively impacts peripheral vascular health. Whether sitting similarly impacts central cardiovascular hemodynamics and vascular stiffness is unknown. Purpose: Determine if prolonged sitting increases central blood pressure, aortic pulse wave reflection and vascular stiffness. Methods: In 10 subjects (Age=22±2 yrs, BMI=28±4kg/m², 3 females), brachial artery pulse wave analysis was performed before (baseline-BL), during, and after 3 hours of sitting. Aortic pulse wave velocity (PWV) was examined before and after sitting using carotid applanation tonometry coupled with oscillometry performed on left upper-thigh. For mechanistic insight, intermittent pneumatic compression (IPC) was applied during sitting (i.e., 3, 120 …

The Contribution Of Small And Large Sensory Afferents To Postural Control In Patients With Peripheral Neuropathy, Li Li, Shuqi Zhang, John Dobson

Health Sciences & Kinesiology: Faculty Publications

Peripheral neuropathy (PN) is a multifarious disorder that is caused by damage to the peripheral nerves. Although the symptoms of PN vary with the etiology, most cases are characterized by impaired tactile and proprioceptive sensation that progresses in a distal to proximal manner. Balance also tends to deteriorate as the disorder becomes more severe, and those afflicted are substantially more likely to fall while walking compared with those who are healthy. Most patients with PN walk more cautiously and with greater stride variability than age-matched controls, but the majority of their falls occur when they must react to a perturbation …

Longitudinal Tracking Of Physiological State With Electromyographic Signals., Robert Warren Stallard

Electronic Theses and Dissertations

Electrophysiological measurements have been used in recent history to classify instantaneous physiological configurations, e.g., hand gestures. This work investigates the feasibility of working with changes in physiological configurations over time (i.e., longitudinally) using a variety of algorithms from the machine learning domain. We demonstrate a high degree of classification accuracy for a binary classification problem derived from electromyography measurements before and after a 35-day bedrest. The problem difficulty is increased with a more dynamic experiment testing for changes in astronaut sensorimotor performance by taking electromyography and force plate measurements before, during, and after a jump from a small platform. A …

The Effects Of A Physical Activity Program Called "Minds-In-Motion-The Maze" On Balance And Motor Skills In Middle School Aged Students., Liliana Vargas

Electronic Theses and Dissertations

Competing time demands in the curriculum have left physical education as a low priority among schools. Consequently, school aged children are not meeting the recommended 150 mins/wk of physical activity. We studied the effects of Minds in Motion-MAZE on middle school aged (n=74) children’s balance and motor skills. Minds in Motion-MAZE is a low cost physical activity program designed to improve balance and motor control. Participants participated in Minds in Motion-MAZE for 15 minutes during the 7^th period. A multivariate test did not show a statistical significance of participating in Minds in Motion-MAZE and improved balance and motor skills. …
