The Effects Of Seat Post Angle In Cycling Performance, Saori Hanaki-Martin

Theses and Dissertations--Kinesiology and Health Promotion

Triathlon involves three different modes of endurance events, swim, bike and run, consecutively. Transitions between events are critical to be successful in the sport; however, many triathletes report impaired running performance due to adverse residual effects from cycling. One of the strategies that triathletes use to manage the adverse effects is to use a bicycle with a more vertical seat post angle. There is limited evidence that support the effectiveness of such bicycle geometry, but many of these studies lacks ecological validity.

Twelve triathletes and cyclists completed a 20-km simulated course with instrumentations for 3D motion, kinetic, and electromyographic analyses …

Use Of A Video Game Based Balance Training Intervention On The Balance And Function Of Children With Developmental Disabilities, Gina C. Siconolfi-Morris

Theses and Dissertations--Rehabilitation Sciences

Many children with developmental disabilities (DD) have physical impairments and limitations in their participation. Rehabilitation research often focuses on either physical impairments or participation restrictions, when both need to be investigated. The purposes of these two studies were to evaluate an at home therapist directed video game balance training intervention on balance, gait velocity (GV), hip strength and activities of children with DD. The pilot study was a single-subject non-concurrent multiple baseline design. Balance measures included: weight bearing symmetry; center of pressure area and velocity; time to boundary mean minima and standard deviation; and timed up and go. The participant’s …

Physical Activity, Sleep Patterns, And Health Outcomes In University Law Enforcement Officers, Nicole C. Koebke

Theses and Dissertations--Kinesiology and Health Promotion

Research indicates that law enforcement officers (LEOs) have a higher prevalence of developing coronary artery disease (CAD) compared to the general population. Sleep deprivation and physical inactivity have been found to be related to many risk factors for CAD. This cross-sectional study examined the health status and the relationship between sleep and physical activity outcomes versus CAD risk factors among 27 University LEOs. The subjects’ health behaviors, and CAD and metabolic syndrome risk factors were described using basic statistics. Accelerometer derived sleep and physical activity outcomes were correlated to measures of health to identify potential relationships. 33% of LEOs were …

Relationships Of Access And Affordability To Household Food Security Status Among Rural, Low Income Caregivers, Jodi Elaine Marani

Theses and Dissertations--Kinesiology and Health Promotion

Household food security status in rural areas is a significant issue facing caregivers as positive health outcomes depend on appropriate access to healthy foods necessary to lead an active life. Access and affordability of healthy foods are two mediating factors of household food security that may be improved to ultimately increase rates of food security and overall health status among rural, low income populations.

The purpose of the study was to examine the factors of access and affordability of nutritionally adequate food sources in one rural community in relation to food security status through the perspective of its caregivers. In …

The Clinical Usefulness Of Vector Coding Variability In Female Runners With And Without Patellofemoral Pain, Tommy Joseph Cunningham

Theses and Dissertations--Kinesiology and Health Promotion

It has been suggested that Patellofemoral Pain (PFP) may be the result of a coordinate state which exhibits less joint coordination variability. The ability to relate joint coordination variability to PFP pathology could have many clinical uses; however, evidence to support clinical application is lacking. Vector coding’s coupling angle variability (CAV) has been introduced as a possible analysis method to quantify joint coordination variability. The purpose of this study was to assess the clinical usefulness of CAV measures from a dynamical systems perspective. This involved establishing the precision limits of CAV measures when physiological conditions are held constant, altering control …
