Evaluating The Effects Of Wearable Technologies To Improve Physical Activity Levels For College Students With Intellectual And Developmental Disabilities, Kelly Nicole Kraiss

Doctoral Dissertations

Regular physical activity can decrease the likelihood of being overweight or obese as well as other negative health outcomes. Adults with intellectual and developmental disabilities (I/DD) are more likely to be obese, less likely to be physically active, and at greater risk for health conditions and disease. Thus, there is a need for interventions that aim to increase the physical activity levels of adults with I/DD. However, interventions and related research in this field are limited. The purpose of this dissertation was to examine two independent single-subject design interventions that incorporated the use of wearable technology, a Fitbit ...

Effects Of A Raised Surface On Lower Extremity Kinematics, Kinetics, And Muscle Activation During A Sidecut In Recreational Female Softball Players, Lauren Elizabeth Schroeder May 2017

Effects Of A Raised Surface On Lower Extremity Kinematics, Kinetics, And Muscle Activation During A Sidecut In Recreational Female Softball Players, Lauren Elizabeth Schroeder

Masters Theses

Noncontact anterior cruciate ligament (ACL) injury is a common sports-related injury. “High-risk” dynamic movements, such as a sidecut, have been associated with increasing the risk of noncontact ACL injury. Certain biomechanical abnormalities, specifically at the hip and knee, and neuromuscular abnormalities, such as unbalanced quadriceps-to-hamstrings activation ratios and certain activation patterns prior to initial contact and after initial contact, have also been associated with an increased likelihood of noncontact ACL injuries occurring. Approximately 78% of all NCAA Division I softball game-day injuries are classified as noncontact where there is no direct contact to a player. Internal derangement of the knee ...

Effects Of Synthetic Turf And Shockpads On Impact Attenuation Related Biomechanics During Drop Landing, Hang Qu

Masters Theses

Synthetic turf has been widely utilized in sports since 1964. Discrepancies, however, in injury incidence on synthetic turf and natural grass have been reported throughout studies. Adding a shock pad under synthetic turf carpet is claimed to aid in energy absorption and decrease impact loading. Although some studies have conducted materials tests and compared mechanical characteristics of synthetic turf with different shock pads, no studies have examined biomechanical characteristics of impact related human movements on an infilled synthetic turf system with different underlying shock pads. The purpose of this research was to investigate effects of an infilled synthetic turf with ...

Effects Of Wider Step Width On Knee Biomechanics In Obese And Healthy-Weight Participants During Stair Ascent, Derek Scott Yocum

Masters Theses

An increased likelihood of developing obesity-related knee osteoarthritis may be associated with increased peak internal knee abduction moment. Increases in step width may act to reduce this moment. This study focused on how step width influenced the knee joint during stair ascent by healthy and obese participants. Participants ascended stairs while walking at their preferred speed and under one of two step width conditions – preferred and increased. Obese participants experienced greater mediolateral and vertical ground reaction forces (GRFs), as well as increased peak knee extensor moments and push-off peak internal knee adduction moments. The findings of this study indicate that ...

Static Frontal Plane Tibiofemoral Alignments And Their Effects On Knee Biomechanics During Level Walking And Stair Ascent Tasks, Hunter Jared Bennett

Doctoral Dissertations

Knee osteoarthritis is a degenerative joint disease that can onset due to abnormal knee adduction moments (KAMs), which are related to frontal plane knee joint alignment. Gait modifications including toe-in (TI) and wider step widths have been proposed as individual intervention strategies, but have not been previously combined, to reduce abnormal frontal plane loading in healthy and osteoarthritic populations. Study One investigated clinical based measurements to predict radiographic frontal plane knee joint alignment, measured as the mechanical axis angle (MA). Study Two compared three different hip joint center estimation methods on MA predictions using three-dimensional motion capture. Study Three and ...

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 Dec 2014

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, 2001). Researchers ...

Associations Of Total Activity Counts And Physical Activity Intensity Levels With The Metabolic Syndrome: A Structural Equation Modeling Approach, Dana Lizbeth Wolff May 2014

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.

In order to ...
