Playground And Garden Physical Activity Levels In Young Children, Ashlyn Nicole Schwartz May 2017

Playground And Garden Physical Activity Levels In Young Children, Ashlyn Nicole Schwartz

Masters Theses

The purpose of this study was to determine the differences in time spent in physical activity (PA), as assessed by the amount of time spent in PA, vector magnitude (counts/15 sec.), MET values, and energy expenditure (kcal/min), between two outdoor environments (natural playground and garden) in preschool children. Participants were twenty-five children (4.4±0.7 years) enrolled in a university laboratory preschool. PA was assessed using an ActiGraph GT3X+ accelerometer that was worn on the right hip. Each child completed four randomly ordered conditions (30 min each), which included two bouts of unstructured PA on the natural ...


Accuracy Of Energy Expenditure Predictions And Activity Identification In Consumer-Based Activity Monitors, James Andrew Woodman Aug 2015

Accuracy Of Energy Expenditure Predictions And Activity Identification In Consumer-Based Activity Monitors, James Andrew Woodman

Masters Theses

INTRODUCTION: Consumer-based physical activity (PA) monitors are increasingly common, and must be validated against criterion measures to determine which models are accurate. Such studies will aid PA intervention research and individual consumers purchasing these devices. METHODS: Thirty participants (mean ±[plus or minus] SD; age, 25.5 ± 3.7 years; BMI, 24.9 ± 2.6 kg/m2[meters squared]) completed a structured PA routine including 11 activities ranging from sedentary behaviors to vigorous intensities. During the routine participants wore an Oxycon portable calorimeter (criterion measure of energy expenditure (EE)), a Basis Peak and Garmin Vivofit on the non-dominant wrist, and three ...


Elementary School Teachers’ Perceptions Of The Role Of Physical Activity In Schools, Amanda Millwood Harrison May 2014

Elementary School Teachers’ Perceptions Of The Role Of Physical Activity In Schools, Amanda Millwood Harrison

Masters Theses

The purpose of this qualitative study was to examine and describe elementary school teachers’ perceptions of physical activity among children in an urban, Title I, school in Tennessee. Twelve elementary teachers in Second and Third grade were interviewed using a semi-structured interview. The interview protocol was developed to guide participants from broader concepts regarding physical activity to more focused discussions on the use of physical activity during the school day.

Data presented examines the perceptions of teachers’ overall view of physical activity among children during school hours, the amount of physical activity children engaged in during school hours, the impact ...


Classification Accuracy Of The Wrist-Worn Genea Accelerometer During Structured Activity Bouts: A Cross-Validation Study, Whitney Allegra Welch Aug 2012

Classification Accuracy Of The Wrist-Worn Genea Accelerometer During Structured Activity Bouts: A Cross-Validation Study, Whitney Allegra Welch

Masters Theses

Purpose: The purpose of this study is to determine whether the left wrist cutpoints of Esliger et al., for the triaxial GENEA accelerometer, are accurate for predicting intensity categories during 14 different activities including; treadmill-based, home and office, and sport activities. Methods: 130 adults wore a GENEA accelerometer on their left wrist while performing various lifestyle activities. The Oxycon Mobile Portable Metabolic Unit was used to measure oxygen uptake during each activity. Statistical analysis used Spearman’s rank correlations to determine the relationship between measured and estimated intensity classifications. Cross tabulation tables were constructed to describe under or over estimation ...


The Effectiveness Of A Health Communication Campaign In Increasing Awareness Of The 2008 Physical Activity Guidelines For Americans Among College Students Living In Residence Halls, Virginia Marie Frederick May 2012

The Effectiveness Of A Health Communication Campaign In Increasing Awareness Of The 2008 Physical Activity Guidelines For Americans Among College Students Living In Residence Halls, Virginia Marie Frederick

Masters Theses

The college years are an important time for young adults to learn and implement healthy lifestyle behaviors, such as physical activity (PA). In order to develop these habits, college students should be made aware of public health recommendations, such as the 2008 Physical Activity Guidelines for Americans (PAG). However, no studies have examined the level of awareness of these guidelines among college students. PURPOSE: To determine the level of awareness of the 2008 PAG in college students and study the effectiveness of a PA health communication campaign (HCC) designed to increase awareness. METHODS: This study utilized a quasi-experimental, two-group design ...


High And Low Active Transit Accessibility On Greenways: The Relationship With Physical Activity, Dana Lizbeth Wolff Aug 2011

High And Low Active Transit Accessibility On Greenways: The Relationship With Physical Activity, Dana Lizbeth Wolff

Masters Theses

Greenways (GW) can be sited to increase the potential for individuals to access the GW through active transit (AT) and provide opportunities for individuals to meet PA guidelines. PURPOSE: To determine if GWs, with varying AT access potential, relate to user characteristics and their GW-related PA. METHODS: A trail intercept survey measuring access mode, GW-specific PA, and demographics of GW users was administered to 611 adults on 2 GWs with high and low AT potential (GWhigh vs. GWlow). RESULTS: Users of GWhigh(N=216) compared to GWlow (N=400) were more likely to be younger, male ...
