Relational Memory: A Daytime Nap Facilitates The Abstraction Of General Concepts, Hiuyan Lau, Sara E. Alger, William Fishbein

Publications and Research

It is increasingly evident that sleep strengthens memory. However, it is not clear whether sleep promotes relational memory, resultant of the integration of disparate memory traces into memory networks linked by commonalities. The present study investigates the effect of a daytime nap, immediately after learning or after a delay, on a relational memory task that requires abstraction of general concept from separately learned items. Specifically, participants learned English meanings of Chinese characters with overlapping semantic components called radicals. They were later tested on new characters sharing the same radicals and on explicitly stating the general concepts represented by the radicals. …

Investigation Of Biomolecular Interactions For Development Of Sensors And Diagnostics, Xiaojuan Zhang

Theses and Dissertations

The highly specific recognition processes between biomolecules mediate various crucial biological processes. Uncovering the molecular basis of these interactions is of great fundamental and applied importance. This research work focuses on understanding the interactions of several biomolecular recognition systems and processes that can provide fundamental information to aid in the rational design of sensing and molecular recognition tools. Initially, a reliable and versatile platform was developed to investigate biomolecular interactions at a molecular level. This involved several techniques, including biomolecule functionalization to enable attachment to self-assembled monolayers as well as atomic force microscopy (AFM) based force spectroscopy to uncover the …

Launching Return-Oriented Programming Attacks Against Randomized Relocatable Executables, Limin Liu, Jin Han, Debin Gao, Jiwu Jing, Daren Zha

Research Collection School Of Computing and Information Systems

Since the day it was proposed, return-oriented programming has shown to be an effective and powerful attack technique against the write or execute only (W ⊕ X) protection. However, a general belief in the previous research is, systems deployed with address space randomization where the executables are also randomized at run-time are able to defend against return-oriented programming, as the addresses of all instructions are randomized. In this paper, we show that due to the weakness of current address space randomization technique, there are still ways of launching return-oriented programming attacks against those well-protected systems efficiently. We demonstrate and evaluate …

An Examination Of Diet, Acculturation And Risk Factors For Heart Disease Among Jamaican Immigrants, Carol Renee Oladele

USF Tampa Graduate Theses and Dissertations

Background: The South Florida region is home to over 85,000 Jamaican immigrants. Yet, little is known about the dietary intakes and predictors of risk of disease within this immigrant group. An assessment of dietary intakes and the development of dietary intake methodologies specific to the Jamaican population was important as it permitted accurate estimation of the nutrient intakes of this immigrant population whose dietary habits are not well documented. In addition, nothing is known about the prevalence of risk factors for heart disease or factors influencing risk factors among this immigrant group. The purpose of this study was to assess …

Discriminating Between Copers And Those With Chronic Ankle Instability With Clinical Outcomes, Erik A. Wikstrom, Jessica Plante

International Journal of Exercise Science: Conference Proceedings

Introduction: Chronic ankle instability (CAI) is a common consequence of lateral ankle sprains and a leading cause of post-traumatic ankle osteoarthritis. Despite a history of a lateral ankle sprain, there are some individuals (copers) who appear to have a mechanism that allows them to avoid recurrent lateral ankle sprains and giving way episodes. To date, research has identified differences in perceptual (e.g. self-assessed disability), mechanical (e.g. ligament laxity), and sensorimotor (e.g. balance) outcomes between copers and those with CAI. However, the vast majority of these outcomes are considered research and/or laboratory based and thus impractical for most clinicians to use …

Comparing Dominant And Non-Dominant Torque And Work Using Biodex 3 Isokinetic Protocol For Knee Flexors And Extensors, Joshua Sparks, Jeremy Carter, Kelly Brooks

International Journal of Exercise Science: Conference Proceedings

INTRODUCTION. There is often a misconception when looking at comparing dominant and non-dominant limbs of any sort. Although there will be a lack of control in non-dominant limbs compared to dominant, the amount of torque and power associated with each limb may be equal; even so, there may be an instance of bilateral deficit, where even though the dominant limb may be used to do work on a specific limb, the non-dominant limb may still receive strength benefits. PURPOSE. The main purpose of this study is to directly relate ability (torque and total work) in both dominant and non-dominate limbs …

Influences On Pulmonary And Muscular V’O2-Kinetics, Uwe Drescher, Uwe Hoffmann

International Journal of Exercise Science: Conference Proceedings

Introduction

Muscular and respiratory V’O2-kinetics are influenced by many factors. At cellular level muscular V’O2 (V’O2musc) is affected by O2-delivery and O2-consumption. Further, these factors can be divided into muscle perfusion, capillary density, enzyme activity, mitochondrial proliferation, muscle fiber composition and some more.

Focusing on the difference between V’O2resp and V’O2musc the venous blood volume, the venous O2-stores and the dynamics of cardiac output can be identified as influences. These influences result in a time delay and a distortion of V’O2resp. Usually exercise step responses are used for estimating V’O2resp-kinetics. But it has to be recognized, that V’O2resp may be …

Micro-Fracture Simulation In Human Vertebral Body Due To Weight Lifting, Harcharan S. Ranu

International Journal of Exercise Science: Conference Proceedings

Abstract Lumbar vertebrae are a heavily loaded component of the human body. They are subjected to repetitive loading in daily activities. However, limited information on failure mechanism of lumbar vertebrae are available to date. Thus, the need to develop an analytical model to predict stress-fracture characteristics of vertebral body. A linear elastic fracture mechanics approach has been considered and a mathematical model has been proposed so that the predictions can be made more easily related to the occurrence of injury. Study reveals that for a person weighing 1334 N and lifting a weight of 345 kg during squat exercise causes …

Injury Simulation In Female Gymnasts, Harcharan S. Ranu

International Journal of Exercise Science: Conference Proceedings

Abstract Female gymnasts often place un-physiological extreme repetitive loading on their bodies during the common maneuvers characteristic of this sport. Thus, it was necessity to provide quantitative and qualitative analyses of impact behavior of feet of gymnasts. The response of fracture or injury due to jumping is also important in designing safety equipment related to sports. A linear elastic fracture mechanics approach has been used for this analysis. Typical behavior of crack growth rate for a force of F= 6.1 KN and m being 1.25, revealed that 6 landings were sufficient to initiate micro-fracture of bone due to landing after …

A Leucine-Enriched Diet Enhances Overload-Induced Growth And Markers Of Protein Synthesis In Aged Rat Skeletal Muscle, Rengfei Shi, Hoke Whitworth, William Mixon, Scott E. Gordon

International Journal of Exercise Science: Conference Proceedings

Introduction: The hypertrophic response to overload in fast-twitch skeletal muscle is impaired in aged humans and rats, and impaired protein synthesis pathway activation is hypothesized to be a contributing factor. Muscle growth occurs when protein synthesis exceeds protein degradation. Dietary supplementation of the essential amino acid leucine has been shown to enhance protein synthesis in both young and aged skeletal muscle. Leucine acts in part by activating mammalian target of rapamycin (mTOR; a key upstream regulator of protein synthesis pathways) as well as by attenuating the activation of 5'-AMP-activated protein kinase (AMPK; a negative regulator of mTOR and protein synthesis). …

A Leucine-Enriched Diet Enhances Overload-Induced Growth And Suppresses Markers Of Protein Degradation In Aged Rat Skeletal Muscle, Scott E. Gordon, William Mixon, Hoke Whitworth, Rengfei Shi

International Journal of Exercise Science: Conference Proceedings

Introduction: The hypertrophic response to overload in fast-twitch skeletal muscle is impaired in aged humans and rats, and upregulation of protein degradation pathways are hypothesized to be a contributing factor. Muscle growth occurs when protein synthesis is greater than protein degradation. Dietary supplementation of the essential amino acid leucine has been shown to reduce protein degradation in both young and aged skeletal muscle. Specifically, leucine acts in part by attenuating 5'-AMP-activated protein kinase (AMPK) activation as well as the translocation of the forkhead box transcription factor 3A (FoxO3, known to promote transcription of mRNAs encoding degradation pathway proteins) to the …

Isokinetic Muscle Strength And Fatigue Evaluation Following A Combined Aerobic And Resistance Training Program On A Gravity Independent Flywheel Device, Joshua A. Cotter, Tomasz Owerkowicz, Alvin M. Yu, Marinelle L. Camilon, Theresa Hoang, Per A. Tesch, Vincent J. Caiozzo, Gregory R. Adams

International Journal of Exercise Science: Conference Proceedings

Exposure to microgravity imposes changes on the musculoskeletal and cardiovascular systems leading to decreases in aerobic capacity, muscular strength, and muscular fatigue (1). Anti-gravity muscles, those that play a postural role in a standard gravity environment such as the soleus and quadriceps, are most affected by microgravity (2) with nearly all musculature affected with extended spaceflight (3). The multi-mode exercise device (M-MED) is a gravity independent device that provides both high force resistance type and low force aerobic type modes of exercise. Consequently, the M-MED has the ability to enhance both skeletal muscle function through resistance training exercises as well …

Genetic Regulation Of Myofiber Hypertrophy?, Anna Thalacker-Mercer, Xiangqin Cui, Michael Stec, Edward Merritt, Marcas Bamman

International Journal of Exercise Science: Conference Proceedings

Introduction. Progressive, resistance exercise training (RT) induces skeletal muscle hypertrophy, increases strength, power, and quality of muscle, and is potentially the most promising method to regenerate and re-grow muscle in populations suffering from involuntary atrophy. However, we have previously shown that there is a large degree of intersubject variability for myofiber hypertrophy in response to RT with adults having no response [-16μm2 (mean myofiber growth), Non], a modest response (1111μm2, Mod), or an extreme hypertrophic response (2475μm2, Xtr). Underlying mechanisms for this differential growth response are largely unknown. Therefore, the purpose of this study was to determine whether differences in …

Effects Of Multivitamin Supplementation On Heart Rate Response In Aerobically Untrained College Aged Students, Greg A. Ryan, Charles P. Katica, Stacy H. Bishop, Robert L. Herron, Andy M. Bosak, Mark Sloniger

International Journal of Exercise Science: Conference Proceedings

Multivitamin use is increasingly prevalent in the US among most every population. Yet, previous research noted no performance benefits among individuals following a supplementation period. This study focused on the potential physiological benefits from a three week multivitamin supplementation period using 24 (20.9 ± 2.6yr) aerobically untrained college aged students. Subjects were divided equally into three groups (placebo = PL, multivitamin = MV, control = CL) and asked to perform separate eight minute bouts of exercise, consisting of six min of moderate (60%VO2max) intensity followed immediately by two min of high (85%VO2max) intensity exercise on a cycle ergometer. Following the …

Effect Of Treadmill Versus Elliptical Exercise On Calcaneal Stiffness Index Among College Age Females, Kelly Maloney, Sandie Walker, Stephanie M. Otto Ph.D.

International Journal of Exercise Science: Conference Proceedings

Osteoporosis is a disease that affects many older individuals, resulting in a decrease in bone density. Involvement in impact loading sports has been associated with greater stiffness index (SI) of the calcaneus when compared to non-impact sports and abstinence from sports. However, comparisons between the effectiveness of impact and non-impact exercise equipment on calcaneal SI is less clear. The purpose of this study was to examine the effect of treadmill versus elliptical exercise on calcaneal SI.

Daily Physical Activity And Bone Health Among High School Students, Stephanie M. Otto Ph.D., Don Morgan Ph.D., Richard S. Farley Ph.D., Jwa K. Kim Ph.D., Dana K. Fuller Ph.D., Jennifer L. Caputo Ph.D.

International Journal of Exercise Science: Conference Proceedings

With advancements in healthcare and public education, life expectancy is increasing and the prevalence of age related health conditions such as osteoporosis are rising. It is well known that children and adolescents who engage in healthy behaviors are more likely to carry those behaviors into adulthood. More specifically, children and adolescents who engage in weight bearing physical activity have higher bone density and are less likely to develop osteoporosis later in life. Furthermore, technology that measures daily physical activity is improving and individuals are interested in the amount of activity they and their children should participate in to remain healthy. …

Body Composition And Physical Fitness Of Students In High School Vs. Students Enrolled In High School Sports Academia Programs, Gunnhildur Hinriksdóttir, Frosti Sigurðsson, Anna S. Ólafsdóttir, Ragnar Bjarnason, Sigurbjörn Á. Arngrímsson

International Journal of Exercise Science: Conference Proceedings

In recent years more and more high schools in Iceland are offering sports academia programs. These programs are intended for teenage athletes in various sports who have the potential of becoming elite athletes. The sports academia programs make it easier for these student athletes to focus on training for their sport while attending high school, and thereby, enable them to get a good education and enhance their athletic potential. These programs also have the potential to reduce drop-out in sports because it is easier for the students to balance athletics and academics. Nevertheless, sports performance is not necessarily linked to …

Body Composition, Physical Activity And Fitness In Children With Moderate-To-Severe Intellectual Disability, Sigurbjorn A. Arngrimsson, Ingi T. Einarsson

International Journal of Exercise Science: Conference Proceedings

Introduction: The prevalence of overweight and obesity has been rising in most parts of the world over the past two decades (1, 2). This rise could pose even a greater problem for people with intellectual disability (ID) because they are more likely to be obese than people without ID (3). Furthermore, research has shown that a sedentary lifestyle is more prevalent among people with ID than otherwise healthy people in modern society (4). In the general population, the adverse effects of obesity on health begin early in life and physical inactivity and adiposity are associated with metabolic diseases and cancers …

The Physiological Stress Response To Anaerobic Exercise Is Altered Following Sodium Bicarbonate Supplementation, Dan J. Peart, Richard Kirk, Angela Hillman, Bryna Chrismas, Leigh Madden, Jason Siegler, Rebecca Vince

International Journal of Exercise Science: Conference Proceedings

Sodium bicarbonate (NaHCO3) is a nutritional aid that is proposed to enhance performance by reducing the state of exercise induced acidosis, however research is currently equivocal. Despite this, most research still focuses on its effects upon performance, and not whether the reduced acidosis impacts upon any other factors related to exercise. There is some research to suggest that such a reduction in [H+] can attenuate a number of physiological stress pathways such as stress hormones (1, 4), heat shock protein 72 (HSP72) and oxidative stress (3), suggesting a potential role in exercise recovery. However there are some limitations with this …
