Knoxville Moves: Log-In And Get Mobile, Courtney Marie Monroe

Doctoral Dissertations

This dissertation evaluated 1) the efficacy of a course-based Internet-technology intervention rooted in social cognitive theory (SCT) for increasing step counts in university faculty and staff, and 2) the effect of online social support tools on step counts among adults using a randomized control trial.

Thirty-six sedentary/insufficiently active university faculty and staff participated in an eight-week, Internet-delivered walking intervention. They received an Omron HJ-720ITC pedometer, personal step goals, and access to a Blackboard LearnTM website comprised of SCTbased features. Outcomes included daily steps, social support, self-regulation, self-efficacy, and outcome expectations. Participants significantly increased their average daily steps (p < 0.001) between baseline and week 1 by 1800. A similar increase in daily steps was observed between baseline and all other intervention weeks (p < 0.001). Social support and self-regulation significantly improved (p < 0.001). These findings helped inform the design of the second study.

Active Families In The Great Outdoors: A Family-Centered Program To Increase Physical Activity Levels, Perceptions, And Behaviors, Jennifer Irene Flynn

Doctoral Dissertations

Physical activity levels of adults and children are low, and the amount of time children spend being active outdoors is decreasing. Parents play a critical role in developing health behaviors of children and ways to increase physical activity and encourage an active family culture are needed. Promotion of family outdoor physical activity, which includes at least one parent and one child from a home engaging in physical activity together, is understudied. Therefore, the purpose of this dissertation was to 1) describe the type, frequency, and duration of family physical activity, 2) determine whether changes in the duration and number of …

Associations Of Total Activity Counts And Physical Activity Intensity Levels With The Metabolic Syndrome: A Structural Equation Modeling Approach, Dana Lizbeth Wolff

Doctoral Dissertations

To clarify the protective benefits of physical activity (PA), epidemiologists and public health researchers continue to seek improved methods of assessing PA. In particular, accelerometers have gained acceptance with researchers as they provide reliable estimates of PA and can record both the amount and intensity of ambulatory movement. However, there is concern that accelerometer data reduction techniques may not provide quantitatively accurate measurements of time spent in various PA intensity categories. One way to circumvent these inaccuracies is to use the accelerometer-derived total activity counts (TAC), which is a more direct expression of what the monitor records.

The Accuracy Of The Progressive Aerobic Cardiovascular Endurance Run To Estimate Aerobic Fitness In Youth, Stacy Nicole Scott

Masters Theses

The FITNESSGRAM’s Progressive Aerobic Cardiovascular Endurance Run (PACER) test is a commonly used field test to estimate peak oxygen uptake (VO_2peak) in youth. However, little research has been conducted to determine the influence of weight status on the accuracy of the equations used to estimate VO_2peak. Purpose: To assess the agreement between VO_2peak measured using indirect calorimetry during the PACER and estimated VO_2peak in normal weight and overweight youth and to determine the influence of weight status on the accuracy of estimated VO_2peak in 10-15 year old youth. Methods: The study …

Validity Of Estimating Minute-By-Minute Energy Expenditure Of Continuous Walking Bouts By Accelerometry, Erin E. Kuffel, Scott E. Crouter, Jere D. Haas, Edward A. Frongillo, David R. Bassett

Kinesiology, Recreation, and Sport Studies Publications and Other Works

Background

Objective measurement of physical activity remains an important challenge. For wearable monitors such as accelerometer-based physical activity monitors, more accurate methods are needed to convert activity counts into energy expenditure (EE).

Purpose

The purpose of this study was to examine the accuracy of the refined Crouter 2-Regression Model (C2RM) for estimating EE during the transition from rest to walking and walking to rest. A secondary purpose was to determine the extent of overestimation in minute-by-minute EE between the refined C2RM and the 2006 C2RM.

Methods

Thirty volunteers (age, 28 ± 7.7 yrs) performed 15 minutes of seated rest, 8 …

Why Is There Still So Much Confusion About Vo2 Plateau? A Re-Examination Of The Work Of A.V. Hill, Richard Vincent Castle

Masters Theses

Maximal oxygen uptake (VO_2max) is regarded as the gold standard for assessing aerobic fitness. In 1923, Hill et al. proposed that VO_2max represents the maximal ability of the body to take in and consume O₂ during strenuous exercise. Recently, however, controversy has arisen over the issue of whether a leveling off, or "plateau" in VO₂ is necessary to verify attainment of VO_2max. Purpose: To compare two different VO_2max protocols and determine if both protocols show direct evidence of an upper limit on VO₂. Methods: Nine runners (18-35 years old) completed …

Validity Of The Crouter 2-Regression Model For Predicting Energy Expenditure: Transitions From Rest To Activity, Erin E. Kuffel

Masters Theses

The Crouter 2-regression model (15) is a new approach for predicting MET values. However, the Crouter 2-regression model may misclassify walking/jogging during transition periods (i.e. during the first and last minute of the activity) due to the high coefficient of variation resulting in an overestimation of MET values. Purpose: The purpose was to examine the Crouter 2-regression model for predicting MET values during transitions from rest to activity and back to rest. It was hypothesized that starting a walking bout partway through a minute will lead to a misclassification, due to the high coefficient of variation, and therefore over-predict MET …
