Knoxville Moves: Log-In And Get Mobile, Courtney Marie Monroe

Doctoral Dissertations

This dissertation evaluated 1) the efficacy of a course-based Internet-technology intervention rooted in social cognitive theory (SCT) for increasing step counts in university faculty and staff, and 2) the effect of online social support tools on step counts among adults using a randomized control trial.

Thirty-six sedentary/insufficiently active university faculty and staff participated in an eight-week, Internet-delivered walking intervention. They received an Omron HJ-720ITC pedometer, personal step goals, and access to a Blackboard LearnTM website comprised of SCTbased features. Outcomes included daily steps, social support, self-regulation, self-efficacy, and outcome expectations. Participants significantly increased their average daily steps (p < 0.001) between baseline and week 1 by 1800. A similar increase in daily steps was observed between baseline and all other intervention weeks (p < 0.001). Social support and self-regulation significantly improved (p < 0.001). These findings helped inform the design of the second study.

Investigating The Role Of A Reduced-Instruction Approach In Implicit And Explicit Motor Learning Strategies, Kevin Michael Fisher

Doctoral Dissertations

Traditional explanations of motor learning contend that skills are learned explicitly in a process in which learners accumulate declarative knowledge and progress through distinct stages of learning (e.g., Fitts & Posner, 1967). More recently, implicit approaches to instruction have been used in an attempt to bypass accumulation of explicit knowledge. Such approaches have been shown to facilitate motor learning compared to explicit instruction by enhancing skill retention and transfer under conditions involving distraction, increased pressure, or physical stress (Masters & Poolton, 2012). One method thought to invoke implicit learning involves instructions in the form of an analogy (Liao & Masters, …

Active Families In The Great Outdoors: A Family-Centered Program To Increase Physical Activity Levels, Perceptions, And Behaviors, Jennifer Irene Flynn

Doctoral Dissertations

Physical activity levels of adults and children are low, and the amount of time children spend being active outdoors is decreasing. Parents play a critical role in developing health behaviors of children and ways to increase physical activity and encourage an active family culture are needed. Promotion of family outdoor physical activity, which includes at least one parent and one child from a home engaging in physical activity together, is understudied. Therefore, the purpose of this dissertation was to 1) describe the type, frequency, and duration of family physical activity, 2) determine whether changes in the duration and number of …

Effects Of Different Approach Directions And Sizes Of Selected Tennis Forehand Strokes On Knee Biomechanics, Louise Barbara Beggs

Masters Theses

Tennis is a global sport and knee injuries are prevalent, ranging from acute to chronic and minor, to severe. Different directional movements and speeds involved in tennis may lead to a higher chance of injury due to changing loading rates at the knee. This study investigates effects of diagonal and lateral forehand strokes with step or lunge on kinematics and kinetics of the knee on the dominant leg during simulated tennis play. Ten National Tennis Ranking Program (NTRP) players level 4.0 upwards were recruited for the study. A motion analysis system was used to obtain three-dimensional joint kinematics, and force …

Knee Biomechanical Characteristics Of Knee Unfriendly Movements In 42-Form Tai Ji, Chen Wen

Masters Theses

Tai Ji was one of recommended non-pharmacologic treatments for knee OA, but it is not clear that if all of the Tai Ji movements would be suitable and beneficial for knee OA patients. The purpose of this study was to examine 1) GRF and knee kinematic and kinetic characteristics of the identified knee unfriendly Tai Ji movements including lunges, pushdown, kick and pseudo-step 2) effects of high- and low-pose of these movements on those characteristics, and 3) compare biomechanical variables between the Tai Ji movements and slow waking. Seventeen volunteers performed three trials in each of eight movement conditions: high …

Associations Of Total Activity Counts And Physical Activity Intensity Levels With The Metabolic Syndrome: A Structural Equation Modeling Approach, Dana Lizbeth Wolff

Doctoral Dissertations

To clarify the protective benefits of physical activity (PA), epidemiologists and public health researchers continue to seek improved methods of assessing PA. In particular, accelerometers have gained acceptance with researchers as they provide reliable estimates of PA and can record both the amount and intensity of ambulatory movement. However, there is concern that accelerometer data reduction techniques may not provide quantitatively accurate measurements of time spent in various PA intensity categories. One way to circumvent these inaccuracies is to use the accelerometer-derived total activity counts (TAC), which is a more direct expression of what the monitor records.

"It Starts With Having A Conversation": Lesbian Student-Athletes' Experience Of U.S. Ncaa Division I Sport, Jamie Fynes

Masters Theses

According to Griffin (1998), the U.S. NCAA Division I sport environment is not very welcoming for lesbian student-athletes because of existing negative myths and stereotypes. In addition, the experiences of both current and former lesbian collegiate athletes is an underrepresented research topic. Therefore, the purpose of this study was to explore the experiences of 10 former U.S. NCAA Division I lesbian student-athletes using a semi-structured personal identity interview guide (Fisher, 1997) and Consensual Qualitative Research (CQR) (Hill, Thompson, & Williams, 1997). Five domains, 19 categories, and related core ideas were found in the transcribed interviews. In Domain I: Stereotypes and …

Elementary School Teachers’ Perceptions Of The Role Of Physical Activity In Schools, Amanda Millwood Harrison

Masters Theses

The purpose of this qualitative study was to examine and describe elementary school teachers’ perceptions of physical activity among children in an urban, Title I, school in Tennessee. Twelve elementary teachers in Second and Third grade were interviewed using a semi-structured interview. The interview protocol was developed to guide participants from broader concepts regarding physical activity to more focused discussions on the use of physical activity during the school day.

Data presented examines the perceptions of teachers’ overall view of physical activity among children during school hours, the amount of physical activity children engaged in during school hours, the impact …

Physical Activity And Its Effect On Reducing Disease: A Literature Review Of The National Runner's Health Study, Graham William Edson

Kinesiology, Recreation, and Sport Studies Publications and Other Works

In 1996, Dr. Paul Williams began The National Runner’s Health Study. The study had over one hundred thousand respondents who were questioned about their physical activity habits (walking or running), diet, weight, height, and use or previous use of tobacco and alcohol. Some of the participants were involved in case studies of several years. Primarily, the study tested the effects of vigorous physical activity and its ability to reduce disease. For close to twenty years, Dr. Williams has continued an impressive amount of research on various topics in the health and exercise field. The study is one of the most …
