Physical Activity And Sarcopenia In Older Adults, Nathan Frederick Meier Jan 2018

Physical Activity And Sarcopenia In Older Adults, Nathan Frederick Meier

Graduate Theses and Dissertations

The aging process is typically associated with loss of muscle mass, strength, and function. At a certain threshold, low levels of muscle mass, strength, and function are considered a disease called sarcopenia, which is associated with increased risk of falls, loss of independence, mobility issues, and mortality. Evidence suggests some of the risk factors for sarcopenia, such as sedentary lifestyle, low physical activity, bedrest, chronic disease, certain drug treatments, malnutrition, anabolic resistance, intermuscular adipose tissue infiltration, and decreased neuromuscular activation, are modifiable. Also, both the prevention and treatment of sarcopenia call for prescription of physical activity. Therefore, the overall interest ...

Physical Activity In The Preschool Classroom: An Approach To Enhance Executive Functioning Through The Move For Thought Prek-K Program, Morgan Nichole Morse

Graduate Theses and Dissertations

The purpose of this study was to assess the Move For Thought PreK-K Program (M4T) activities on inhibitory control via response time and accuracy, as well as the level of feasibility, engagement, and program satisfaction. Eight preschool (3-5 years old) classes participated with four classrooms being randomly assigned to the early implementation group (intervention, N=52) and four classrooms to the late implementation group (control, N=51), whom would get to participate once the study was complete.

Prior to and following the cessation of the eight-week intervention, all children participated in the computerized day/night executive function task to assess ...


Estimation Of Physical Activity Intensity Using Triaxial Actigraph Accelerometers In Youth Populations: Impact Of Data Type, Attachment Site, And Modeling Approach, Including Adaptations Of The Sojourn Method For Varied Use In Youth, Paul Hibbing Jan 2016

Estimation Of Physical Activity Intensity Using Triaxial Actigraph Accelerometers In Youth Populations: Impact Of Data Type, Attachment Site, And Modeling Approach, Including Adaptations Of The Sojourn Method For Varied Use In Youth, Paul Hibbing

Graduate Theses and Dissertations

Adequate physical activity (PA) in youth is essential for short- and long-term health. However, it is difficult to perform large-scale assessments of youth PA levels and be assured of accurate results. Recent developments in accelerometer-based PA monitoring for adults (e.g. the Sojourn method) have enhanced the accuracy attainable by those devices, but the same has not been accomplished for youth. PURPOSE: The purpose of this study was to develop and cross-validate versions of the established Sojourn method that can be used for research with youth. METHODS: The study involved two phases. In Phase 1, existing ActiGraph monitor data from ...


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 ...


Validation And Calibration Of Self-Report Methods: The Youth Activity Profile, Pedro Frederico De Saint-Maurice Maduro Jan 2013

Validation And Calibration Of Self-Report Methods: The Youth Activity Profile, Pedro Frederico De Saint-Maurice Maduro

Graduate Theses and Dissertations

The development of more accurate and precise methods of assessing physical activity behavior is an important public health research priority. Objective monitoring devices have advantages but the high cost and burden of data processing make them impractical for large scale applications. Subjective (survey-based) tools are inexpensive and easy to use but these suffer from questionable validity. Objective measures are often used to validate less accurate measures such as subjective instruments but this does not directly improve the accuracy or precision of the self-report instrument. The proposed line of research developed and tested a calibration equation approach that enabled data from ...


Integrated Classroom Physical Activity: Examining Perceived Need Satisfaction And Academic Performance In Children, Miriam Ann Blom Skrade Jan 2013

Integrated Classroom Physical Activity: Examining Perceived Need Satisfaction And Academic Performance In Children, Miriam Ann Blom Skrade

Graduate Theses and Dissertations

Physical activity is related to better academic performance and prevention of childhood obesity. Classroom-based physical activities, based on recent research studies, seem to target both areas successfully. Move for Thought (M4T) is a recently developed kit that integrates physical activities into academic lessons in the classroom. This thesis is the first to examine the kit's impact on children's motivation and math performance. The study aimed to see (a) if eight weeks of M4T integrated with math, compared to traditional lessons (control), would elicit a gain in math performance and (b) if the basic psychological needs in math (autonomy ...


The Effectiveness Of Self-Monitoring Tools And Texting Prompts To Increase Physical Activity In The Workplace, Molly Webb Jan 2013

The Effectiveness Of Self-Monitoring Tools And Texting Prompts To Increase Physical Activity In The Workplace, Molly Webb

Graduate Theses and Dissertations

Lack of physical activity is one contributing factor to the obesity epidemic currently affecting the United States. Increasingly sedentary jobs have added to this societal lack of activity, so worksites are a promising location for interventions to increase physical activity. Such interventions have shown mixed results and can be costly. New technologies including self-monitoring devices, text messaging reminders, and online health coaching are promising tools to improve such interventions. The purpose of this study was to determine the effectiveness on increasing physical activity of employees in a worksite setting of the combined use of a self-monitoring device (SWA) along with ...


Methods Of Physical Activity Assessment In Older Adults, Colleen Marie Campbell Jan 2012

Methods Of Physical Activity Assessment In Older Adults, Colleen Marie Campbell

Graduate Theses and Dissertations

Introduction: This study examined the validity of several methods of physical activity assessment in older adults. The physical activity questionnaires (PAQs) used included two designed for use with older adults known as the Yale Physical Activity Survey (YPAS) and the Physical Activity Scale for the Elderly (PASE) and one designed for use in the general population, the 7 Day Physical Activity Recall (PAR). These PAQs along with one accelerometer, the ActiGraph GT1M (GT1M), were examined in comparison to the criterion method, the SenseWear Pro 3 Armband (SP3).

Methods: Participants (n = 36; age = 69.7 ± 5.9 years) wore the SP3 ...


Using A Social-Ecological Model To Examine Obesity Interventions, Susan Lee Brown Jan 2011

Using A Social-Ecological Model To Examine Obesity Interventions, Susan Lee Brown

Graduate Theses and Dissertations

The Nutrition and Physical Activity Program to Prevent Obesity and Other Chronic Diseases at the Centers for Disease Control and Prevention employs a five-level Social-Ecological Model (SEM) to address and understand the issues of overweight and obesity (Hamre et al., 2006). The model suggests that there are multiple levels of influence, and that effective prevention and reduction programs should address each of these levels. This research evaluated the effectiveness of programs and institutions with an emphasis on reducing childhood overweight and obesity. The first study evaluated the effectiveness of the Trim Kids program (Sothern, von Almen & Schumacher, 2001), a program ...
