The Effect Of Music Cadence On Step Frequency In The Recreational Runner, Micaela A. Galosky Jul 2014

The Effect Of Music Cadence On Step Frequency In The Recreational Runner, Micaela A. Galosky

Graduate Theses and Dissertations

Music appears to have advantageous effects during exercise as it has been shown to increase motivation, decrease ratings of perceived exertion (RPE), and improve exercise performance. The improvement of running performance in particular, is the main effect recreational runners want to focus on as many want to improve their time in road races. Running velocity, indicated by a faster time to completion is thought to improve with an increase in step frequency, step length, or a combination of these variables. Currently, there is limited research that observes methods to help increase step frequency or step length. The manipulation of music ...


Analysis And Application Of Passive Gait Rehabilitation Methods, Ismet Handzic Jul 2014

Analysis And Application Of Passive Gait Rehabilitation Methods, Ismet Handzic

Graduate Theses and Dissertations

Human gait is elegant and efficient in propelling the body forward. While a healthy human gait is symmetric, any deviation from symmetry can cause inefficiencies to the entire body. Such asymmetries may present themselves in hemiplegic patients, prosthetic users, lower limb injuries, limb height and weight discrepancies, or abnormal overground foot rolling. In this dissertation, practical passive methods to alleviate such asymmetric walking dynamics are presented. The novel concepts presented in this manuscript can all be related and applied to passive gait rehabilitation, that is, the rehabilitation of a person's gait through methods that do not require external power ...


Asymmetric Unilateral Transfemoral Prosthetic Simulator, Tyagi Ramakrishnan May 2014

Asymmetric Unilateral Transfemoral Prosthetic Simulator, Tyagi Ramakrishnan

Graduate Theses and Dissertations

amputation, which includes reduced force generation at the knee and ankle, reduced control of the leg, and different mass properties relative to their intact leg. The physical change in the prosthetic leg leads to gait asymmetries that include spatial, temporal, or force differences. This altered gait can lead to an increase in energy consumption and pain due to compensating forces and torques. The asymmetric prosthesis demonstrated in this research aims to find a balance between the different types of asymmetries to provide a gait that is more symmetric and to make it overall easier for an amputee to walk.

Formative Evaluation Of Intervention Methods Designed To Improve Behavior Change Strategies, Erin Mackinzie Nelson Jan 2014

Formative Evaluation Of Intervention Methods Designed To Improve Behavior Change Strategies, Erin Mackinzie Nelson

Graduate Theses and Dissertations

Obesity is a complex condition, often resulting from an imbalance between energy expenditure and energy intake. Preventing and treating this condition is challenging and sustainable weight loss is often unsuccessful. Behavior change models are becoming more popular in combating obesity. Motivational interviewing (MI) is a method used to promote behavior change in individuals by activating internal motivation for change. The use of technology including self-monitoring, text messaging and online health coaching is also emerging as a useful method for improving health behaviors. The purpose of this study was to determine the effectiveness of these approaches in improving behavior change strategies ...


The Blossom Project Online: Use Of A Behaviorally-Based Website To Promote Physical Activity And Prevent Excessive Gestational Weight Gain In Previously Sedentary Pregnant Women, Katie Marie Smith Jan 2014

The Blossom Project Online: Use Of A Behaviorally-Based Website To Promote Physical Activity And Prevent Excessive Gestational Weight Gain In Previously Sedentary Pregnant Women, Katie Marie Smith

Graduate Theses and Dissertations

Obesity and incidence of chronic disease continue to rise in the United States. The current medical paradigm focuses on treatment of chronic disease. A shift from the management of disease to prevention of obesity and its associated co-morbidities including diabetes mellitus and cardiovascular disease is necessary to protect the health of future generations. Pregnancy is a "teachable moment" offering a time when many women are motivated to make healthier lifestyle choices to optimize the health of their unborn child. This critical stage of the life cycle offers a unique opportunity to influence the health of future generations by modifying the ...


Childhood Obesity Prevention Intervention: Exploring Food Preferences And Physical Activity Self-Efficacy, Hannah Ostrander Jan 2014

Childhood Obesity Prevention Intervention: Exploring Food Preferences And Physical Activity Self-Efficacy, Hannah Ostrander

Graduate Theses and Dissertations

BACKGROUND: Overweight and obese children and adolescents are at greater risk for being overweight or obese as adults as well as developing one or more chronic diseases. Approximately one third (31.8%) of children in the Unites States are either overweight or obese (16.9% being obese). The causes of obesity are complex and multifactorial, an interaction between biological, psychological, and environmental factors. Physical activity and dietary habits are two major contributing modifiable factors in determining one's health and weight status. Interventions are needed to help curb the obesity epidemic by working toward improving the health status of children ...


Association Of Sleep And Inflammation In Law Enforcement, Braden Ray Everding Jan 2014

Association Of Sleep And Inflammation In Law Enforcement, Braden Ray Everding

Graduate Theses and Dissertations

The law enforcement profession has been associated with an increased risk for cardiovascular diseases (CVD), but the mechanisms are unclear. Previous research suggests a mechanism other than traditional CVD risk factors may be an underlying cause. Sleep health has been reported as an issue among LEO. Poor sleep health has been associated with increased CVD risk. Sleep disorders have been shown to increase biomarkers of inflammation. CVD is increasingly being recognized as an inflammatory disease. We sought to further investigate this issue by evaluating the sleep health, CVD risk, mental health, and inflammatory biomarkers of 133 LEO in the Iowa ...
