Effect Of Actigraph's Low Frequency Extension For Estimating Steps And Physical Activity Intensity, Yuri Feito, Lyndsey M. Hornbuckle, Lauren A. Reid, Scott E. Crouter

Faculty Articles

This study examined the effects of the ActiGraph’s (AG) low-frequency extension (LFE) filter on steps and physical activity classification in the free-living environment. Thirty-four African-American women (age, 24.5±5.2 years; BMI, 24.9±4.5 kg/m2) had daily activity measured simultaneously with an AG-GT3X+ accelerometer and a New Lifestyles NL-800 pedometer for seven days. Steps per day (steps/day) and time (minutes/day) spent in sedentary, light, and moderate-to-vigorous physical activity (MVPA) were examined with and without the LFE filter (AG-LFE and AG-N, respectively). The AG-LFE recorded more total steps (13,723±4,983 steps/day) compared to AG-N and NL-800 (6,172±2,838 and 5,817±3,037 steps/day, respectively; p<0.001). Compared to the AG-N, the AG-LFE estimated less time in sedentary behaviors (518.7±92.1 vs. 504.2±105.4 min/day, respectively; p<0.001), and more time in light (247.7±70.4 vs. 279.1±74.7 min/day, respectively; p<0.001) and MVPA (18.9±16.9 vs. 21.5±18.2 min/day, respectively; p<0.001), respectively. These data suggest that steps and physical activity classifications will be affected when using the ActiGraph with and without the LFE filter. Future research should investigate the accuracy of these measures using the LFE filter.

Theses and Dissertations

Physical activity impacts health and disease in multiple body tissues including the intervertebral discs. 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 …

Open Accessarticle Food Shopping And Acquisition Behaviors In Relation To Bmi Among Residents Of Low-Income Communities In South Carolina, Angela D. Liese, Xiaonan Ma, Brett Hutto, Patrica A. Sharpe, Bethany A. Bell, Sarah Wilcox

Faculty Publications

Low-income areas in which residents have poor access to healthy foods have been referred to as “food deserts.” It is thought that improving food access may help curb the obesity epidemic. Little is known about where residents of food deserts shop and if shopping habits are associated with body mass index (BMI). We evaluated the association of food shopping and acquisition (e.g., obtaining food from church, food pantries, etc.) with BMI among 459 residents of low-income communities from two South Carolina counties, 81% of whom lived in United States Department of Agriculture-designated food deserts. Participants were interviewed about food shopping …

Post-Fatigue Recovery Of Power, Postural Control And Physical Function In Older Women, Stephen A. Foulis, Stephanie L. Jones, Richard E. Van Emmerik, Jane A. Kent

Exercise and Sport Studies: Faculty Publications

Low muscle power, particularly at high velocities, has been linked to poor physical function in older adults. Any loss in muscle power following fatiguing exercise or daily activities could impact physical function and postural control until power has fully recovered. To test the overall hypothesis that a common task such as walking can result in prolonged power loss and decreased physical function and balance, 17 healthy older (66–81 years) women completed a 32-min walking test (32MWT) designed to induce neuromuscular fatigue, followed by 60min of recovery (60R). Fatigue and recovery of knee extensor muscle power (3 velocities) were quantified by …

Comparing Reaction Time And Postural Stabilization Based On Activity Groups In Older Adults, Lauren Marie Merk

Graduate Theses and Dissertations

The purpose of this study was to compare reaction time and postural stabilization between activity groups in older adults. These variables are important because older adults are at a high fall risk and two major contributors to fall risk are postural stabilization and reaction time. This study examined if the activity group of an older adult had any influence on reaction time and postural stabilization. Fifty-nine older adults aged 66.46 ± 9.47 years old were used in the study. Thirteen subjects were in the master’s athletes which are individuals over the age of 40 who competed in a nationally sanctioned …

What You Know Makes A Difference: Physical Activity Maintenance And Adherence Of Collegiate Students, Vista Beasley, Brooke Thompson, Patrick R. Young, Itay Basevitch

Journal of Counseling and Psychology

For decades, exercise psychology researchers dismissed health/exercise knowledge as a determinant of physical activity (PA). We sought to overturn this misconception, showing that psychological theory may serve as a basis for informing physical education curriculum. Based on social cognitive and self-determined motivation theories, we examined health/exercise knowledge as a determinant of collegiate students’ PA maintenance (i.e., ≥ 6 months of regular PA involvement); adherence to United States Department of Health and Human Services (USDHHS) 2008 PA guidelines; and PA types (i.e., aerobic, weight training). Collegiate students (n = 231) provided data via online survey. ANOVA analyses revealed that knowledge …

Understanding Differences Between Summer Vs. School Obesogenic Behaviors Of Children: The Structured Days Hypothesis, Keith Brazendale, Michael W. Beets, R. Glenn Weaver, Russell R. Pate, Gabrielle Turner-Mcgrievy, Andrew T. Kaczynski, Jessica L. Chandler, Amy Bohnert, Paul T. Von Hippel

Faculty Publications

Background: Although the scientific community has acknowledged modest improvements can be made to weight status and obesogenic behaviors (i.e., physical activity, sedentary/screen time, diet, and sleep) during the school year, studies suggests improvements are erased as elementary-age children are released to summer vacation. Emerging evidence shows children return to school after summer vacation displaying accelerated weight gain compared to the weight gained occurring during the school year. Understanding how summer days differ from when children are in school is, therefore, essential.

Discussion: There is limited evidence on the etiology of accelerated weight gain during summer, with few studies comparing obesogenic …

The Relationship Between Generalized Joint Laxity And Hip Cartilage Thickness In Ballet And Modern Dancers, Noelle Jeanette Tuttle

Theses and Dissertations

Generalized joint laxity (GJL), a condition in which most joints of the body move beyond the accepted normal range of motion, is present in many ballet and modern dancers. It has been associated with an increased risk of injury, decreased muscle strength, and greater landing forces. Increased joint laxity results in joint instability and may precede the development of osteoarthritis, which is associated with a reduction in cartilage thickness. We hypothesized that dancers with GJL would have decreased hip cartilage thickness, as well as greater hip adduction angles and greater ground reaction force on landings. Twenty female ballet and modern …

The Effects Of A Short-Term Endurance Training Program With Blood Flow Restriction Cuffs Versus Acsm Recommended Endurance Training On Arterial Compliance And Muscular Adaptations In Recreationally Active Males, Brittany N. Esparza

Theses and Dissertations

RESULTS: Significant time and group interaction found in cardiac ejection time (p<.05). Significant condition difference between blood flow restriction (BFR) and control for heart rate (HR) max (p=.05) and maximum oxygen consumption (VO2) (p<.05). Significant time difference found in pulse wave velocity femoral to distal (p<.05). Significant repetition main effect (p<.01) for root mean square (RMS) and median frequency (MDF) of Thorstensson. Significant time and group interaction in vastus lateralis of MDF (p<.01). Significant repetition main effect for RMS and MDF ratio (p<.01) Significant time and repetition interaction in vastus lateralis of RMS ratio (p<.03)

CONCLUSION: The BFR session showed improvement in both post HR max and post VO2 in comparison to the control group. This may have been caused by increased tolerance to pain/metabolic by-products for HR and increased efficiency at extracting oxygen for VO2

Sagittal Abdominal Diameter, Waist Circumference, And Bmi As Predictors Of Multiple Measures Of Glucose Metabolism: An Nhanes Investigation Of U.S. Adults, Shelby Anne Firouzi

Fasting glucose, HbA1c, and HOMA-IR …

The Validity Of Submaximal Exercise Testing In Obese Women, Gabrielle Ringenberg

Mahurin Honors College Capstone Experience/Thesis Projects

Background: Submaximal exercise tests use heart rate responses to low-to-moderate intensity activity in order to predict cardiorespiratory fitness (VO_2max). Currently used tests may be inappropriate for obese populations as obese women have altered heart rate responses to exercise. The purpose of this project is to test the validity of the Modified Bruce Protocol submaximal treadmill test in obese women. Methods: Normal-weight (NWG) and obese women (OBG) completed the Modified Bruce submaximal treadmill test (to predict VO_2max using previously validated equations) and a maximal graded exercise test on a treadmill using the Standard Bruce Protocol (to obtain an …

Assessment Of Endpoint Criteria And Perceived Barriers During Maximal Cardiorespiratory Testing Among Pregnant Women, Caitlin Hesse

Mahurin Honors College Capstone Experience/Thesis Projects

PURPOSE: Plateau in oxygen consumption (VO₂) is the primary indicator for determining if an individual has reached their true maximal aerobic capacity (Howley et al., 1995). Although age and gender-specific secondary criteria (i.e. additional criteria that can be used to identify one’s attainment of maximal effort) have been developed for the healthy population, no secondary criteria have been established for pregnant women (Edvarsen et al., 2014). The primary purpose of this study was to analyze secondary endpoint criteria during VO_2max testing among pregnant women during the 2nd trimester. A secondary purpose was to identify emotional and physical …

Earnest, Paul J. Arciero, Colin Wilborn, Douglas S. Kalman, Jeffrey R. Stout, Darryn S. Willoughby, Bill Campbell, Shawn M. Arent, Laurent Bannock, Abbie E. Smith-Ryan, Jose Antonio

Faculty Publications

Position Statement: The International Society of Sports Nutrition (ISSN) bases the following position stand on a critical analysis of the literature regarding the effects of diet types (macronutrient composition; eating styles) and their influence on body composition. The ISSN has concluded the following. 1) There is a multitude of diet types and eating styles, whereby numerous subtypes fall under each major dietary archetype. 2) All body composition assessment methods have strengths and limitations. 3) Diets primarily focused on fat loss are driven by a sustained caloric deficit. The higher the baseline body fat level, the more aggressively the caloric deficit …

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: …

Background

Globally most children do not engage in enough physical activity. Day length and weather conditions have been identified as determinants of physical activity, although how they may be overcome as barriers is not clear. We aim to examine if and how relationships between children’s physical activity and weather and day length vary between countries and identify settings in which children were better able to maintain activity levels given the weather conditions they experienced.

Methods

In this repeated measures study, we used data from 23,451 participants in the International Children’s Accelerometry Database (ICAD). Daily accelerometer-measured physical activity (counts per minute; …
