Fluid flow within the disc is an indicator of disc health that can be observed using diffusion weighted magnetic resonance imaging. We monitored activity levels of 26 participants, age 35 to 55 yrs, using Actigraph accelerometers for four days to evaluate vigorous-intensity activity, moderate to vigorous-intensity activity, and sedentary time. Participants underwent structural and diffusion weighted magnetic resonance imaging to evaluate intervertebral disc health and fluid flow. They also underwent bone density scans, carotid artery ultrasounds, a treadmill test, and a physical exam for pain, range …


Examination Of The Monoamine Oxidase A Gene Promoter On Motivation To Exercise And Levels Of Voluntary Physical Activity, Erin M. Kinney Jun 2017

Examination Of The Monoamine Oxidase A Gene Promoter On Motivation To Exercise And Levels Of Voluntary Physical Activity, Erin M. Kinney

Senior Theses

Purpose: The purpose of this study was to examine the genetic basis underlying voluntary exercise. Monoamine oxidase A (MAO-A) is an enzyme that acts on monoamine neurotransmitters, such as dopamine, to cause inactivation. There are several polymorphisms in the promoter region of the MAO-A gene, and these variations change transcriptional activity and the amount of MAO-A produced, leading to alterations in available dopamine levels. Interestingly, polymorphisms in MAO-A have been associated recently with physical activity level. This study sought to determine whether there is an association between motivation to exercise, levels of voluntary physical activity, and MAO-A gene polymorphisms.

Methods: …

Effect Of Activity Trackers And Text Messaging On Exercise, Fitness, And Physical Activity Self-Efficacy Of Middle School Students, Alison F. Pittman

Nursing Theses and Dissertations

A decrease in physical activity as children age is a contributing factor to the U.S. obesity epidemic. Middle school children are particularly vulnerable to sedentary activities. Activity trackers show promise as a means to motivate children and adults to increase physical activity (PA). This study examined the effect of a text messaging intervention and use of activity trackers with a companion social website on the body mass index (BMI), body fat percentage, physical fitness, and PA self-efficacy of middle school children. Children aged 11-14 (n=102) were randomly assigned to one of three groups for a 10-week intervention: activity tracker group; …


Evaluating The Effects Of Wearable Technologies To Improve Physical Activity Levels For College Students With Intellectual And Developmental Disabilities, Kelly Nicole Kraiss May 2017

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, in order …


The Effects Of Including Physical Activity In Classrooms With Children With Language Disorders, Shelby E. Auer May 2017

The Effects Of Including Physical Activity In Classrooms With Children With Language Disorders, Shelby E. Auer

Honors Theses

As obesity becomes a rising concern in the United States and the importance of high test scores continues to add stress to students, physical activity opportunities are beginning to become less frequent in schools. The Center for Disease Control reports a total of 12.7 million children were classified as obese from 2011 to 2012 (CDC, 2015). While many researchers have also acknowledged this trend, the majority of studies focus on the correlation of physical activity in the classroom with increases in fitness and cognitive functioning levels among average population students, much like the research done by Webster, Russ, Vazou, Goh, …

The Facilitators And Barriers To Physical Activity: The Perspective Of Adults With Disabilities, Elizabeth K. Keener

Cal Poly Humboldt theses and projects

Children and adults with disabilities are at greater risk of developing higher levels of obesity, and chronic diseases associated with obesity (Centers for Disease Control and Prevention [CDC], 2014). Physical activity is crucial to maintaining health, mobility, and slowing disease progression for all people, especially those experiencing disability. Despite this fact, physical activity levels in individuals with disabilities are very low (Centers for Disease Control and Prevention [CDC], 2006). Lower physical activity levels in are the result of a complex interactions of personal and environmental factors that unfold across a lifespan. Research on the facilitators and barriers to physical activity …

An Evaluation Of Older Adults’ Perceptions Of Psychological Well-Being When Participating In Community Centre Programs, Kayla Rellinger

Theses and Dissertations (Comprehensive)

Multi-purpose organizations, such as community centres, provide opportunities for individuals to participate in various physical and social activities. Although, it has been well established that community centres provide the opportunity and environment to promote health behaviour changes among older adults (Jones et al., 2013; Stewart, 1997; Wallace et al., 1998), there is a dearth of research differentiating between physically active and non-active community centre programming. The purpose of the current study was to evaluate whether participating in community centre programming influenced four key measures of perceived psychological well-being, as well as, to evaluate whether the perceived psychological well-being of community …


The Relationship Between Modifiable Lifestyle Factors And Muscle Lipid Depots In Older Adults, Maja Redzic Jan 2017

The Relationship Between Modifiable Lifestyle Factors And Muscle Lipid Depots In Older Adults, Maja Redzic

Theses and Dissertations--Pharmacology and Nutritional Sciences

Muscle health declines with age, influencing both muscle strength and performance. Modifiable lifestyle factors may mitigate muscle dysfunction by altering muscle lipid depots. Vitamin D status, dietary intake, and physical activity each play a role in muscle health during aging. Low vitamin D status (measured as 25(OH)D) is prevalent among older adults and has been associated with functional limitations and impaired physical performance. Previously, 25(OH)D concentrations were inversely associated with extramyocellular lipid (EMCL) and our lab observed a significant positive relationship between 25(OH)D concentrations and IMCL. Studies have shown mixed results regarding the effects dietary fat intake interventions have on …
