Health and Kinesiology Faculty Publications

BACKGROUND

Effective nonpharmacological interventions targeting the enhancement of vascular function and decline of body fatness (BF) in obese individuals are indispensable for the prevention of hypertension and cardiovascular events in young adults. Mat Pilates training (MPT) has gained significant popularity worldwide, yet its effects on vascular function and body composition are understudied. We examined the effects of MPT on vascular function and BF in young obese women with elevated blood pressure (BP). METHODS

Twenty-eight young obese women with elevated BP were randomized to an MPT (n = 14) or a nonexercising control (CON, n = 14) group for 12 …

Use Of A Novel Whole-Body Imaging Approach To Predict Resting Metabolic Rates In Athletes, Nicole Vencil

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Prediction of energy expenditure allows for calculation of appropriate energy requirements, which is especially important for athletes. Resting metabolic rate (RMR) is the greatest contributor to total daily energy expenditure (TDEE) and is typically measured via indirect calorimetry. Indirect calorimetry is not always available, which results in the need for predictive equations. Most predictive equations have been developed with participants resembling the general population and have not been found to be appropriate for athletes, as they may incorrectly predict RMR due to the unique differences of body composition between athletes and the general population. The purpose of the present study …

Exercise and Sport Studies: Faculty Publications

Background: Hepatocellular carcinoma (HCC) is the third most common cause of cancer-related death in the world. Choline deficiency has been well studied in the context of liver disease; however, less is known about the effects of choline supplementation in HCC. Objective: The objective of this study was to test whether choline supplementation could influence the progression of HCC in a high-fat-diet (HFD)-driven mouse model. Methods: Four-day-old male C57BL/6J mice were treated with the chemical carcinogen, 7,12-dimethylbenz[a]anthracene, and were randomly assigned at weaning to a cohort fed an HFD (60% kcal fat) or an HFD with supplemental choline (60% kcal fat, …

Integrating Survivors Of Stroke Into Cardiac Rehabilitation, Elizabeth Wherley Regan

Theses and Dissertations

Stroke is the leading cause of disability in the United States (U.S.). Impairments after stroke typically result in reduced physical activity which increases the risk for stroke recurrence and the development or worsening of comorbid health conditions. Physical activity and exercise behaviors can reduce cardiovascular risk factors and improve endurance for survivors of stroke. Despite these known significant benefits, survivors of stroke face barriers to participating in regular physical activity due to limited self-efficacy, safety concerns, environmental restrictions and lack of accessible community programs.

Cardiac Rehabilitation (CR) is a structured exercise and behavior modification program for people with cardiovascular disease …

Piloting A Smartphone-Based Sedentary Behavior Reduction Intervention For Adults With Overweight Or Obesity: Take A Stand 4 Health, Chelsea Larsen

Theses and Dissertations

INTRODUCTION: Previous studies have shown a relationship between sedentary behavior as an independent and novel risk factor for high blood pressure. However, most of the evidence comes from cross-sectional and experimental studies, with only a few studies examining whether blood pressure is improved in individuals participating in a behavioral intervention. None of these studies utilized mHealth approaches, which hold potential for behavioral interventions, and none have focused on individuals with hypertension as a part of their target population. Therefore, the purpose of the dissertation was to 1) Examine the efficacy of a smartphone-mediated multi-component sedentary behavior reduction intervention for individuals …

Efficacy Of A Motivational Video On Heart Rate, Rpe, And Total Work Performed During Stationary Cycling, Hannah Angelella

Undergraduate Theses and Capstone Projects

Sedentary lifestyles are a very common way of life for 21st century Americans. Lack of enjoyment and motivation are two common factors that deter people from engaging in physical activity and exercise on a regular basis (1). However, it has been found that visual stimulation may help motivate or distract from exertion (2–4). The purpose of this study was to compare the effects of watching a motivational video (Tour de France (MV)) versus a calming video (Bob Ross painting (PV)) while cycling. Ten recreationally active subjects from the University of Lynchburg staff, faculty, and student population partook in a within-subjects …

Kinematic Analyses Of Parkour Landings From As High As 2.7 Meters, Boyi Dai, Jacob S. Layer, Taylour J. Hinshaw, Ross F. Cook, Janet S. Dufek

Integrated Health Sciences Faculty Research

During landing tasks, forces and moments are generated by the musculoskeletal system at surface contact to progressively decelerate the velocity of the body (Dufek and Bates, 1990; McNitt-Gray, 1993). When landing after a forward jump, the body’s downward velocity must be decelerated by an upward acceleration, while its forward velocity needs to be decelerated by a backward acceleration. Inappropriate landing patterns can cause excessive loading to the body, resulting in musculoskeletal injuries. The anterior cruciate ligament is commonly injured by abnormal landing patterns during athletic activities (Dai et al., 2015b; Krosshaug et al., 2007). Military training also involves jump-landing tasks …

Loading Rate Has Little Influence On Tendon Fascicle Mechanics, Michael V. Rosario, Thomas J. Roberts

Biology Faculty Publications

Mechanically, tendons behave like springs and store energy by stretching in proportion to applied stress. This relationship is potentially modified by the rate at which stress is applied, a phenomenon known as viscosity. Viscoelasticity, the combined effects of elasticity and viscosity, can affect maximum strain, the amount of stored energy, and the proportion of energy recovered (resilience). Previous studies of tendons have investigated the functional effects of viscoelasticity, but not at the intermediate durations of loading that are known to occur in fast locomotor events. In this study, we isolated tendon fascicles from rat tails and performed force-controlled tensile tests …

The Effects Of Exercise On Mental Health, Xavier A. Pinex

Honors Thesis

Exercise is an extremely important aspect towards positive mental health. Multiple studies have been done previously that show one benefit or another that exercise has towards mental health, but previously there had been no attempt to summarize the findings of these studies. The benefits that exercise has to an individual’s mental health are numerous, but despite this exercise is an underutilized tool in the quest for better mental health. There are many variables that affect the benefits of exercise to an individual’s mental health and it is important to understand all these variables to understand how to properly exercise to …

Hemodynamic Effects Of Graston Technique On Trigger Points In The Upper Trapezius In Patients With Neck Pain, Hannah Harris

Theses and Dissertations

Background: Non-specific neck pain (NS-NP) is defined as neck pain without a specific diagnosis with varying causes such as poor posture, occupational stressors, and muscular trigger points. Individuals often present with poor posture, including forward head and rounded shoulders. In this position, the upper trapezius muscle becomes tight due to sustained muscle activity leading to trigger points as a result of decreased oxygen to the muscle. Graston Technique® (GT) is a form of manual therapy that uses stainless steel instruments to break down tissue adhesions. GT on trigger points has been presumed to increase local blood flow leading to tissue …

Effects Of Footedness And Stance Asymmetry Confirm An Inter-Leg Metastable Coordination Dynamics Of Standing Posture, Steven J. Harrison, Jeffrey M. Kinsella-Shaw, Dobromir Dotov

Journal Articles

We investigated the patterns of coordination between the left and right legs that support the task of maintaining an upright standing posture. We used cross-wavelet analyses to assess coordination between the centers of pressure under the left and right feet. We recruited participants with a lateralized functional preference for their right leg, and we manipulated whether these participants stood with symmetric/asymmetric stances and whether their eyes were open or closed. Our hypotheses were derived from the Haken-Kelso-Bunz (HKB) model of interlimb coordination dynamics. Consistent with HKB model predictions, we observed (1) coordination taking the form of metastable, transient epochs of …

PURPOSE: To investigate the relationship between sprint speed and tests of jumping performance, muscular strength/endurance, agility, and anaerobic capacity in children and adolescents. METHODS: The analysis included 402 boys and 148 girls (ages 7 to 18 years) participating in a baseline musculoskeletal fitness evaluation. Sprint speed was assessed via a 10-yard and 20-yard sprint. Agility and anaerobic capacity were assessed via the pro-agility and 200-yard shuttle run, …

A Modified Lean And Release Technique To Emphasize Response Inhibition And Action Selection In Reactive Balance, David A.E. Bolton, Manhoud Mansour

Kinesiology and Health Science Faculty Publications

Assessment of reactive balance traditionally imposes some type of perturbation to upright stance or gait followed by measurement of the resultant corrective behavior. These measures include muscle responses, limb movements, ground reaction forces, and even direct neurophysiological measures such as electroencephalography. Using this approach, researchers and clinicians can infer some basic principles regarding how the nervous system controls balance to avoid a fall. One limitation with the way in which these assessments are currently used is that they heavily emphasize reflexive actions without any need to revise automatic postural reactions. Such an exclusive focus on these highly stereotypical reactions would …

The Design And Development Of A Wrist-Hand Orthosis, Amber Gatto

USF Tampa Graduate Theses and Dissertations

Individuals with an incomplete C5-C7 spinal cord injury (SCI) lose grasping abilities but wrist function is almost universally retained. Most rehabilitation techniques apply the tenodesis effect, however, current tenodesis wrist-hand orthoses (WHOs) engage only the thumb and index finger, meaning that only 20% of activities of daily living (ADLs) can be completed.

This study tested the feasibility of a student-designed powered WHO by testing the device on healthy subjects to see if they could complete a variety of ADLs. A simulation software was then used to analyze wrist, thumb, and index finger joint angles. Additionally, an Assistive Technology Survey was …

The Unique Demands Of Playing Posture On Youth Violinists And Violists, Liam Carroll

Honors Program: Senior Projects (Public)

The high prevalence of performing arts injuries is an acknowledged challenge facing the performing arts medicine community. The injuries seem to affect string players the most among orchestral musicians, specifically violinists and violists. The asymmetrical posture, head and neck displacement, and spinal displacement required by the posture to play violin and viola can lead to discomfort or injury in the performer. Performance related musculoskeletal disorders (PRMDs) can have an adverse impact on the life of a musician, preventing them from performing or making it uncomfortable. While there is a large body of research on PRMDs relating to adult musicians, there …

International Journal of Aquatic Research and Education

In 2015, drowning in Brazil was responsible for 6,043 deaths and was the second leading cause of death in children. Although several prevention strategies have been promoted to reduce drowning, most are still based on low levels of evidence. This study evaluated the effectiveness of prevention and water safety interventions in reducing drowning mortality. Data obtained from the National Mortality System for 36 years were split in two time periods to allow the comparison of drowning mortality numbers before and after implementation of SOBRASA’s drowning prevention and water safety programs and to check for any positive effects attributable to such …

A Comparative Analysis Of Army Body Composition Standards For U.S. Army Recruits, Adam Garrett Tedford

Student Theses and Dissertations

PURPOSE: to determine if there were comparable differences using air plethysmography and skinfold measurements to the U.S. Army standard means of measuring BF%. METHODS: BF% was measured in 27 women (21.5 ± 1.8 years) using: 7-site skinfold, air plethysmography, and Army Body Composition (ABC) measurements. The Initial Physical Fitness Test (IPFT) was used to determine if participants met the criteria required for admittance into basic combat training. RESULTS: Pairwise comparisons revealed that the BF% estimate for ABC was 7.05 ± 1.11 % higher compared to skinfold (p < .001). The air plethysmography method (26.9 ± 8.4 %) yielded statistically higher (p < .001) BF% compared to skinfold. Of the 27 total participants, 4 (14.8%) passed IPFT but failed the ABC. CONCLUSION: Primary findings suggest that use of the ABC method for measuring body composition of females overestimated BF% when air plethysmography was used as criterion measure.

Weavil, Jay R. Hydren, Van Reese, Robert H. I. Andtbacka, John R. Hyngstrom, Russell S. Richardson

Health and Kinesiology Faculty Publications

Recognizing the age-related decline in skeletal muscle feed artery (SMFA) vasodilatory function, this study examined the link between vasodilatory and mitochondrial respiratory function in the human vasculature. Twenty-four SMFAs were harvested from young (35 ± 6 yr, n = 9) and old (71 ± 9 yr, n = 15) subjects. Vasodilation in SMFAs was assessed, by pressure myography, in response to flow-induced shear stress, acetylcholine (ACh), and sodium nitroprusside (SNP) while mitochondrial respiration was measured, by respirometry, in permeabilized SMFAs. Endothelium-dependent vasodilation was significantly attenuated in the old, induced by both flow (young: 92 ± 3, old: 45 ± 4%) …

A Comparison Of Variability Between Absolute And Relative Blood Flow Restriction Pressures, Daphney Stanford

Graduate Student Council Research Grants

Overview: My name is Daphney Stanford and I am a first-year doctoral student with good standing in the Health and Kinesiology graduate program. For my Graduate Student Council project we plan to apply blood flow restriction to the upper arm and compare the change in blood flow for three different restrictive pressures.

Intellectual Merit: Currently, blood flow restriction research emphasizes the importance of using a restriction pressure relative to the individual instead of an absolute pressure (e.g. 100 mmHg). To make pressure relative to the individual, the minimum pressure necessary to occlude blood flow is measured and a percentage of …

Effects Of Heated Water-Based Versus Land-Based Exercise Training On Vascular Function In Individuals With Peripheral Artery Disease, Song-Young Park, Alexei Wong, Won-Mok Son, Elizabeth J. Pekas

Health and Kinesiology Faculty Publications

Peripheral artery disease (PAD) is an atherosclerotic disease that is associated with poor vascular function, walking impairment, and reduced quality of life. Land-based exercise therapy (LBET) is frequently recommended to improve walking and reduce symptoms. Recently, evidence has suggested that heated-water exercise therapy (HWET) is an effective intervention for PAD. However, the efficacy of LBET versus HWET in PAD patients had not been elucidated. Therefore, we sought to compare effects of LBET with HWET on cardiovascular function, exercise tolerance, physical function, and body composition in PAD patients. PAD patients (n = 53) were recruited and randomly assigned to a …

Mmp9 Mediates Acute Hyperglycemia-Induced Human Cardiac Stem Cell Death By Upregulating Apoptosis And Pyroptosis In Vitro, Santosh K. Yadav, Tyler N. Kambis, Sumit Kar, Song-Young Park, Paras K. Mishra

Health and Kinesiology Faculty Publications

Providing a conducive microenvironment is critical to increase survival of transplanted stem cells in regenerative therapy. Hyperglycemia promotes stem cell death impairing cardiac regeneration in the diabetic heart. Understanding the molecular mechanisms of high glucose-induced stem cell death is important for improving cardiac regeneration in diabetic patients. Matrix metalloproteinase-9 (MMP9), a collagenase, is upregulated in the diabetic heart, and ablation of MMP9 decreases infarct size in the non-diabetic myocardial infarction heart. In the present study, we aim to investigate whether MMP9 is a mediator of hyperglycemia-induced cell death in human cardiac stem cells (hCSCs) in vitro. We created MMP9−/− hCSCs …

Effects Of A Dual-Task Paradigm And Gait Velocity On Dynamic Gait Stability During Stair Descent, Qipeng Song, Wei Sun, Cui Zhang, Min Mao, Li Li

Health Sciences & Kinesiology: Faculty Publications

Falls during stair negotiation have become one of the leading causes of accidental death. The effects of a concurrent cognitive or manual dual-task paradigm on dynamic gait stability remain uncertain. How much dynamic gait stability is influenced by gait velocity is also not clear. A total of 16 healthy young females descended a staircase under three different walking conditions: descend stairs only (single task), descend stairs while performing subtraction (cognitive dual-task), and descend stairs while carrying a glass of water (manual dual-task). An eight-camera Vicon motion analysis system and a Kistler force plate embedded into the third step of the …

The Effects Of Strength And Conditioning On Functional Movement Screen™ Scores In Secondary School Basketball., Rollin Ross Dexter, Christopher P. Renggli, James May, Lindsay Larkins

Journal of Sports Medicine and Allied Health Sciences: Official Journal of the Ohio Athletic Trainers Association

Purpose: Injury prevention and mitigation are among the primary responsibilities of Athletic Trainers. Research has indicated that basketball players at the secondary-school level suffer up to 2.1 time loss injuries (TLI) per 1,000 athletic exposures (AE). It has been suggested that Functional Movement Screen (FMS™) composite and individual task scores may help determine injury risk. Researchers have suggested that a variety of strength and conditioning strategies may positively alter both composite and individual FMS™ task scores and reduce movement asymmetry. Methods: During a retrospective analysis of the records of all junior varsity and varsity basketball players at one secondary school …
