The Feasibility Of Using The Super Tracker Website For Behavior Changes In The Adolescent Population, Ebony Taylor, Diana Cuy Castellanos

Health and Sport Science Faculty Publications

Research suggests technology such as health websites may be a viable way to effect lifestyle behavior and promote health. Several websites utilize self-monitoring of physical activity and diet as well as provide health-related education as a method to impact behavior. One such site is the Super Tracker tool on ChooseMyPlate.gov, created by the United States Department of Health. The site was created to encourage healthy diet and physical activity within the US population. Therefore, the aim of this original research was to examine the acceptability and feasibility outcomes of a self-monitoring physical activity intervention delivered by the Super Tracker website …

Pre-Training Muscle Characteristics Of Subjects Who Are Obese Determine How Well Exercise Training Will Improve Their Insulin Responsiveness, Charles A. Stuart, Michelle L. Lee, Mark A. South, Mary E. A. Howell, Brian M. Cartwright, Michael W. Ramsey, Michael H. Stone

ETSU Faculty Works

Pre-training muscle characteristics of subjects who are obese determine how well exercise training will improve their insulin responsiveness. J Strength Cond Res 31(3): 798–808, 2017—Only half of prediabetic subjects who are obese who underwent exercise training without weight loss increased their insulin responsiveness. We hypothesized that those who improved their insulin responsiveness might have pretraining characteristics favoring a positive response to exercise training. Thirty nondiabetic subjects who were obese volunteered for 8 weeks of either strength training or endurance training. During training, subjects increased their caloric intake to prevent weight loss. Insulin responsiveness by euglycemic clamps and muscle fiber composition, …

Implementing Comprehensive School Physical Activity Programs: A Wayne State University Case Study, Erin E. Centeio, Nate Mccaughtry

Kinesiology, Health and Sport Studies

Comprehensive school physical activity programs (CSPAPs) have been highlighted by numerous public health and education agencies for their potential to improve the health and academic achievement of American youth. A CSPAP integrates physical activity throughout the school environment before, during and after school by engaging educators, children, families and community organizations. As the design, implementation and evaluation of effective CSPAP programs has inched forward, so has the call for physical education teacher education (PETE) programs to prepare the next generation of physical educators with the skills and knowledge needed to one day lead CSPAP efforts in K-12 schools. The purpose …

Movement Arts, Health Promotion and Leisure Studies Faculty Publications

This study developed an interdisciplinary approach by utilizing the principles of ecological task analysis and movement coordination from areas of motor leaning and biomechanics to examine the skill of slo-pitch softball hitting. The purpose of this study was to examine the influence of a task constraint, stride technique, and an environmental constraint, pitched ball location, on the participants’ movement patterns. Ten elite male softball players participated in the study and a two-way ANOVA of 2 locations of pitch (inside and outside) x 3 strides (open, parallel and closed) repeated measure study was conducted. The results showed that participants demonstrated different …

The Effects Of Flexor Pronator Mass Fatigue On Medial Elbow Stability, Nathaniel Harvey Millard

Theses, Dissertations and Capstones

Introduction: The medial elbow is supported from valgus loading with the ulnar collateral ligament (UCL), the flexor pronator mass (FPM), and the radial head. Fatigue of muscle can lead to a decrease in force production. The decrease in force production can lead to a decrease in joint stability. This study tested the effect of fatigue of the FPM muscles on the width of the medial joint space.

Methods: Thirty-one participants volunteered for this study (18 female and 12 male, 1 excluded; mean height 170.2±10.1 cm, mean weight 71.2±15.6 kg, mean age 21.53±1.87 years old). Ultrasound images of the width of …

The Validity Of Height As A Determinant Of Takeoff Distance To Hurdle One In Ncaa Division Iii Hurdlers 2017, Phillip Wiltshire

Master's Theses

The purpose of this study was to determine if the relationships between the height of a hurdler and the takeoff distance to the first hurdle for men and women as reported by Frye (2008) were valid for NCAA Division III 100 m and 110 m hurdlers. With no specific research reported to validate Frye’s data, it is unclear how the suggested takeoff distances were developed. It is also unclear whether hurdler height or another factor is the main determinant of takeoff distance for the high hurdlers. Participants in this study were three female 100 m hurdlers and four male 110 …

The Neuropsychology Of Sport And Performance, Arthur C. Maerlender

Center for Brain, Biology, and Behavior: Faculty Publications

Neuropsychological theory has been a mainstay for understanding pathology within the brain-behavior context. However, our theories for predicting superior behavior are not as well developed. Sport neuropsychology was developed on the presumption that athletes represent a population in a relatively well-controlled environment for studying brain pathology due to injury. This study of pathology within a high-performance environment has been responsible for identifying the effects of mild traumatic brain injury (mTBI) on individual functioning. Far less attention has been paid to the other end of the performance continuum, and yet, viable brain-behavior hypotheses should hold true across the spectrum of function …

Validity And Reliability Of Baseline Testing In A Standardized Environment, Kathryn L. Higgins, Todd Caze, Arthur C. Maerlender

Center for Brain, Biology, and Behavior: Faculty Publications

Objective — The Immediate Postconcussion Assessment and Cognitive Testing (ImPACT) is a computerized neuropsychological test battery commonly used to determine cognitive recovery from concussion based on comparing post-injury scores to baseline scores. This model is based on the premise that ImPACT baseline test scores are a valid and reliable measure of optimal cognitive function at baseline. Growing evidence suggests that this premise may not be accurate and a large contributor to invalid and unreliable baseline test scores may be the protocol and environment in which baseline tests are administered. This study examined the effects of a standardized environment and administration …

Measurement Of Cortisol In Saliva: A Comparison Of Measurement Error Within And Between International Academic‑Research Laboratories, Jessica L. Calvi, Frances R. Chen, Victoria Brann Benson, Eleanor Brindle, Matt Bristow, Alpana De, Sonja Entringer, Helen Findlay, Christine Heim, Eric A. Hodges, Heiko Klawitter, Sonia Lupien, Holly M. Rus, Jitske Tiemensma, Silvanna Verlezza, Claire-Dominique Walker, Douglas A. Granger

Center for Brain, Biology, and Behavior: Faculty Publications

Objective: Hundreds of scientific publications are produced annually that involve the measurement of cortisol in saliva. Intra- and inter-laboratory variation in salivary cortisol results has the potential to contribute to crossstudy inconsistencies in findings, and the perception that salivary cortisol results are unreliable. This study rigorously estimates sources of measurement variability in the assay of salivary cortisol within and between established international academic-based laboratories that specialize in saliva analyses. One hundred young adults (Mean age: 23.10 years; 62 females) donated 2 mL of whole saliva by passive drool. Each sample was split into multiple- 100 μL aliquots and …

Patterns Of Referral In High School Concussion Management Programs: A Pilot Study Of Consultants From Different Disciplines, Jonathan Lichtenstein, Kate S. Linnea, Arthur C. Maerlender

Center for Brain, Biology, and Behavior: Faculty Publications

School-based concussion management programs cover thousands of young athletes, yet there is little in the way of research to assess program processes or outcomes. This study examined the referral patterns of consultants working with ten high school concussion management programs. In addition to the number of referrals made to specialists, other potential outcome variables were explored. The sample included over 5,000 athlete-seasons and 298 concussions managed directly by certified athletic trainers. All programs used computerized neuropsychological testing (both baseline and post injury). Two groups were compared: five programs used a clinical neuropsychologist (NP) as the testing consultant and five used …

Attention Is Associated With Postural Control In Those With Chronic Ankle Instability, Adam B. Rosen, Nicholas T. Than, William Z. Smith, Jennifer M. Yentes, Melanie L. Mcgrath, Mukul Mukherjee, Sarah A. Myers, Arthur C. Maerlender

Center for Brain, Biology, and Behavior: Faculty Publications

Chronic ankle instability (CAI) is often debilitating and may be affected by a number of intrinsic and environmental factors. Alterations in neurocognitive function and attention may contribute to repetitive injury in those with CAI and influence postural control strategies. Thus, the purpose of this study was to determine if there was a difference in attentional functioning and static postural control among groups of Comparison, Coper and CAI participants and assess the relationship between them within each of the groups. Recruited participants performed single-limb balance trials and completed the CNS Vital Signs (CNSVS) computer-based assessment to assess their attentional function. Center …

Sandbagging On The Immediate Post-Concussion Assessment And Cognitive Testing (Impact) In A High School Athlete Population, Kathryn L. Higgins, Robert L. Denny, Arthur C. Maerlender

Center for Brain, Biology, and Behavior: Faculty Publications

The Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) is a computerized neuropsychological test battery commonly used to assess cognitive functioning after a concussion. It is recommended that application of ImPACT utilizes a baseline administration so athletes have an individualized baseline with which to compare post-injury results should they sustain a concussion. It has been suggested that athletes may provide suboptimal effort, called “sandbagging,” in order to return to their baseline cognitive scores, and thus to play, more quickly. This research examines ImPACT baseline scores when high school athletes were asked to attempt to “sandbag,” and compares those scores with scores …

Psychological And Neural Contributions To Appetite Self-Regulation, Luke E. Stoeckel, Leann L. Birch, Todd Heatherton, Traci Mann, Christine Hunter, Susan Czajkowski, Lisa Onken, Paige K. Berger, Cary R. Savage

Center for Brain, Biology, and Behavior: Faculty Publications

Objective: This paper reviews the state of the science on psychological and neural contributions to appetite self-regulation in the context of obesity. Methods: Three content areas (neural systems and cognitive functions; parenting and early childhood development; and goal setting and goal striving) served to illustrate different perspectives on the psychological and neural factors that contribute to appetite dysregulation in the context of obesity. Talks were initially delivered at an NIH workshop consisting of experts in these three content areas, and then content areas were further developed through a review of the literature.

Pilot Study Of Endurance Runners And Brain Responses Associated With Delay Discounting, Laura E. Martin, Jason-Flor V. Sisante, David R. Wilson, Angela A. Moody, Cary R. Savage, Sandra A. Billinger

Center for Brain, Biology, and Behavior: Faculty Publications

High levels of endurance training have been associated with potentially negative health outcomes and addictive-like symptoms such as exercise in the presence of injury and higher levels of impulsivity. This pilot study examined the relationships among self-report measures of addictive symptoms related to exercise and behavioral and neural measures of impulsivity in endurance runners. We hypothesized endurance runners would have increased preference for immediate rewards and greater activation of cognitive control regions when making decisions involving delayed rewards. Twenty endurance runners (at least 20 miles/week) were recruited to undergo measures of self-report exercise addiction symptoms, impulsive decision-making (delay discounting) and …

Lateral Hypothalamic Activity Indicates Hunger And Satiety States In Humans, Omid Talakoub, Raquel R. Paiva, Matija Milosevic, Marcelo Q. Hoexter, Ruth Franco, Eduardo Alho, Jessie Navarro, Jose F. Pereira Jr., Milos R. Popovic, Cary Savage, Antonio C. Lopes, Pedro Alvarenga, Durval Damiani, Manoel J. Teixeira, Euripides C. Miguel, Erich T. Fonoff, Marcelo C. Batistuzzo, Clement Hamani

Center for Brain, Biology, and Behavior: Faculty Publications

Lateral hypothalamic area (LHA) local field potentials (LFPs) were recorded in a Prader–Willi patient undergoing deep brain stimulation (DBS) for obesity. During hunger, exposure to food-related cues induced an increase in beta/ low-gamma activity. In contrast, recordings during satiety were marked by prominent alpha rhythms. Based on these findings, we have delivered alphafrequency DBS prior to and during food intake. Despite reporting an early sensation of fullness, the patient continued to crave food. This suggests that the pattern of activity in LHA may indicate hunger/satiety states in humans but attest to the complexity of conducting neuromodulation studies in obesity.

Relationship Of Stress, Sleep, Physical Activity, And Food Insecurity On Eating Behaviors And Obesity, Amy Lee Richards

Electronic Theses and Dissertations

There is an urgent need to find effective interventions to prevent and reduce obesity as it is associated with chronic disease and decreased quality of life. Gaining a better understanding of how modifiable variables such as stress, sleep, physical activity, and food insecurity are related to eating behaviors associated with obesity is essential to guide the direction of future interventions and research. Interventions that hold promise need to be tested to determine if they have merit or not. This dissertation presents three papers. Two papers are cross-sectional studies evaluating associations between eating behaviors, obesity, and modifiable variables (stress, sleep, physical …

The Effect Of Delayed Onset Muscle Soreness On Jumping Mechanics And Performance, Ryan J. Engels

Electronic Theses and Dissertations

Background: Delayed onset muscle soreness (DOMS) is an exercise-induced muscle soreness resulting from high-intensity eccentric muscular contractions. DOMS appears to be more prevalent in athletes at the beginning of an athletic season or when new movements or exercise are first introduced. The acute effect of DOMS on jumping mechanics is currently unknown. PURPOSE: The purpose of this study is to determine the effect of delayed onset muscle soreness on vertical jump performance and jumping mechanics. METHODS: Twenty college aged, recreationally active males participated in this study (age: 21.54 ± 2.61; height: 1.82 ± 0.067; mass: 81.36 ± 9.53). Participants were …

EWU Masters Thesis Collection

The purpose of this study was to examine the effect that vibration through self-myofascial release in combination with a dynamic stretch routine had on maximum power output. Twenty-one collegiate volleyball athletes agreed to participate in the study. The design was a randomized cross-over design in which all participants served as their own control by participating in all three interventions, which consisted of; a) dynamic stretch routine (DS), b) non-vibrating foam rolling combined with dynamic stretch routine (NVFR), and c) vibrating foam rolling combined with dynamic stretch routine (VFR). The foam rolling protocol consisted of rolling each limb bilaterally for 30 …

Effects Of An Acute High-Volume Isokinetic Intervention On Circulating Levels Of Tnf-Α And Stnfr: Influence Of Age, Eliott Arroyo Delgado

Electronic Theses and Dissertations

The immune system has been implicated in recovery and muscle regeneration following exercise. In response to muscle damage, the immune system responds with an increase in circulating pro-inflammatory cytokines with the goal of recruiting leukocytes to the damaged area. Tumor Necrosis Factor-alpha (TNF-α), in particular, has been shown to be implicated in both muscle regeneration and muscle wasting. However, it remains unclear whether TNF-α is responsible for the age-related losses in muscle size and function. Also, due to the high clearance rate of TNF-α from circulation, analyzing the circulating levels of soluble TNF-α receptors 1 and 2 (STNFR1 and STNFR2) …

Effects Of An Acute High-Volume Isokinetic Intervention On Inflammatory And Strength Changes: Influence Of Age, Joseph Gordon

Electronic Theses and Dissertations

PURPOSE: The purpose of this study was to compare the effects of a high volume isokinetic intervention on lower body strength and inflammation, as well as markers of muscle damage in the subsequent 48 hours between younger and middle-aged men. METHODS: 19 healthy, recreationally trained men were randomly assigned to two groups, younger adults (YA: 21.8 ± 2.0 y; 90.7 ± 11.6 kg; 21.5 ± 4.1 % body fat), or middle-aged adults (MA: 47.0 ± 4.4 y; 96.0 ± 21.5; 24.8 ± 6.3 % body fat). Both groups reported to the human performance laboratory (HPL) on four separate occasions. On …

Role Of Skeletal Paracrine Signals In The Proliferation And Chondrogenic Differentiation Of Interzone Cells, Parvathy Thampi

Theses and Dissertations--Veterinary Science

Articular cartilage in mammals has a limited intrinsic capacity to repair structural injuries and defects, a fact that contributes to the chronic and progressive nature of osteoarthritis. Current treatment modalities do not enable articular cartilage to achieve a complete and permanent restoration of normal structure and function with large or partial thickness lesions. In contrast to mammals, Mexican axolotl salamanders (Ambystoma mexicanum) have demonstrated the remarkable ability to spontaneously and completely repair even large joint cartilage lesions, an intrinsic healing process that involves interzone cells in the intraarticular space. Further, when interzone tissue is transplanted into critical sized …

The Effects Of Off-Season And In-Season Training On Lactate Threshold In Ncaa Division Iii Female Soccer Players, Rachael M. Nelson

Departmental Honors Projects

Soccer requires a significant amount of aerobic and anaerobic training to improve one’s performance. Because lactate threshold (LT) is an important component of endurance sport performance, testing the LT of soccer players in response to their off-season and in-season training regimens could help to gauge the success of those programs in improving or maintaining fitness levels. This study evaluated the effects of off-season training and in-season training types on LT in 11 NCAA Division III female soccer players (age 19.5 +/- 1.3 years). Off-season training was comprised of aerobic and anaerobic workouts, while in-season training was more sport-specific, and involved …

The relationship between cell free DNA (cf-DNA), C-reactive protein (CRP), creatine kinase (CK), testosterone (T), cortisol (C), testosterone-cortisol ratio (T:C), body mass and body composition were also examined. Eight weightlifters (5 males and 3 females, age = 25 ± 3.5 yr, body mass = 88.3 ± 22.7 kg, height = 173.8 ±8.4 cm) volunteered to participate in this study. Venous blood samples, body mass and body composition were taken six times, each corresponding to the end of …

Frequency Of Chronic Gastrointestinal Distress In Runners: Validity And Reliability Of A Retrospective Questionnaire, Patrick B. Wilson

Human Movement Studies & Special Education Faculty Publications

Gastrointestinal (GI) symptoms may affect up to 90% of competitors during endurance races. Studies have typically assessed GI symptoms retrospectively or only over an acute timeframe, and information on the validity and reliability of the questionnaires employed is lacking. This investigation aimed to estimate the frequency of GI distress experienced by runners over 30 days and to establish the validity and reliability of a retrospective GI symptom questionnaire. Runners (70 men, 75 women) recorded GI symptoms with a prospective journal for 30 days. Retrospective GI symptom data were then collected after the 30-day period on two occasions within one week. …

The Influence Of Different Pre-Exercise Routines On Sprint Performance, Rok Mravljak

Masters Theses

Sprint performance can be enhanced by interventions for short-term (acute) purposes and/or long-term purposes. Acute neuromuscular responses are usually achieved by using different pre-exercise routines at the end of the warm-up period. Recently, there have been several studies examining the effects of various pre-exercise routines on sprint performance, yet there has not been a research study designed that compared the three most commonly used pre-exercise routines in professional and recreational sports (static stretching, dynamic stretching and foam-rolling). Therefore, this study investigated and compared the results of static stretching, dynamic stretching, self-myofascial release and the control group, in order to provide …

The Effect Of Repetitive Head Impacts On Postural Control Over The Course Of A Single Season, Katelyn E. Grimes

College of Graduate Studies: Theses & Dissertations

INTRODUCTION: Recently neurocognitive dysfunction has been linked to poor postural control in concussed athletes. While the detrimental effect of repetitive head impacts on cognitive function have been shown to mirror the effects of concussive injury, very little research has investigated the physical consequences of repetitive head impacts. PURPOSE: To observe the effects of RHI on postural control, both static and dynamic, in NCAA Division I athletes over the course of a single season. METHODS: 9 NCAA Division I football athletes (CON) were recruited from a single university as the experimental group, as well as 9 NCAA Division I baseball players …

The Reliability Of The Navicular Drop Test And Its Transferability To Dynamic Movement, Joshua Krispin

College of Graduate Studies: Theses & Dissertations

Background: Navicular drop can be defined as the distance the navicular tuberosity moves from a standing weight bearing to a standing neutral position, as the subtalar joint moves from a relaxed position to a neutral position. Navicular drop is an important measurement for clinicians used to describe foot function, pronation, and excessive movement seen in several pathologies. Objective: The purpose of this study is to see if navicular drop is influenced by mode or speed of locomotion, if it is will there be other influences such as the forefoot and heel soft tissue, and will those factors influence those measures. …
