Effects Of Glucose Supplementation And Submaximal Exercise On Short-Term Memory Recall, Insaf Abughoush, Jane Cloud

Kinesiology Student Research - Archive

INTRODUCTION: Short-term memory recall is the ability to hold a limited amount of information easily accessible by the brain. Research has shown the positive trends of increased memory through aerobic exercise and regular blood glucose levels in separate studies. Reasons for increased memory from exercise and glucose include building stronger synapses which allows for increased communication between the hippocampus and cortical brain regions and glucose is the primary energy source of the brain. PURPOSE: The purpose of this research study was to find how glucose supplementation and submaximal exercise affects short-term memory recall. METHODS: Five female college students (age 21.75 …

The Effects Of Dietary Nitrate On Oxygen Consumption In College Aged Males, Simi Tometi, Jean Plaisimon

Kinesiology Student Research - Archive

INTRODUCTION: Nitrate (NO3-) is an inorganic polyatomic ion readily available in foods such as lettuce, celery, spinach, and beetroot. Once ingested nitrate is ultimately converted into nitric oxide (NO) by several metabolic pathways. NO is a well-known vasodilator which has been shown to improve exercise performance. Therefore, several researchers have studied the effects of dietary nitrate on exercise performance. Additionally, dietary nitrate supplementation has exhibited the ability to reduce the body's oxygen demand during submaximal work. The Bruce protocol is an incremental maximal exercise test used to determine oxygen consumption. PURPOSE: The purpose of this study was to examine the …

The Influence Of Time Spent In Beginning And End-State Postures On Grasp Choice, Rachel Modersitzki

Undergraduate Honors Capstone Projects

The choice to end comfortably often requires adoption of uncomfortable beginning states, demonstrating that a sequence of movement is planned in advance of movement onset. Many factors may influence the choice of comfortable end-state postures including the greater precision and speed afforded by postures at joint angle mid-ranges (Short & Cauraugh, 1999). There has been no evaluation of the hypothesis that postures are chosen based on minimizing time spent in postures. Typically, the time spent in beginning and end-states are not explicitly constrained, but the end-state posture is likely held for the longer amount of time due to greater precision …

Development And Validation Of Hybrid Continuum/Structural Finite Element Model For Evaluating Foot And Ankle Biomechanics, Saif Alrafeek

Dissertations

Bone is composed of two structures: compact bone and spongy bone. Spongy bone porosity highly affects the strength and the physical endurance of bone to carry loads. Most studies use continuum finite element (FE) approaches to model spongy bone and neglect porosity. Neglecting porosity may not efficiently assist orthopaedic surgeons to treat patients who experience bone physical disability. The purpose of this study is to demonstrate an inexpensive approach that simulates spongy bone with more accurate capturing of porosity and less requirements of bone information. The approach is developed through investigating the mechanical characteristics of spongy bone; that is, by …

Health and Kinesiology Faculty Publications

Little is known about vascular mitochondrial respiratory function and the impact of age. Therefore, skeletal muscle feed arteries were harvested from young (33 ± 7 yr, n = 10), middle-aged (54 ± 5 yr, n = 10), and old (70 ± 7 yr, n = 10) subjects, and mitochondrial respiration as well as citrate synthase (CS) activity were assessed. Complex I (CI) and complex I + II (CI+II) state 3 respiration were greater in young (CI: 10.4 ± 0.8 pmol·s−1·mg−1 and CI+II: 12.4 ± 0.8 pmol·s−1·mg−1, P < 0.05) than middle-aged (CI: 7 ± 0.6 pmol·s−1·mg−1 and CI+II: 8.3 ± 0.5 pmol·s−1·mg−1) and old (CI: 7.2 ± 0.4 pmol·s−1·mg−1 and CI+II: 7.6 ± 0.5 pmol·s−1·mg−1) subjects and, as in the case of complex II (CII) state 3 respiration, were inversely correlated with age [r = −0.56 (CI), r = −0.7 (CI+II), and r = 0.4 (CII), …

There have been limited efforts to characterize the use of mEMDA in behavioral research settings. Objective: The aims of this study were to summarize mEMDA protocols used in research to date, to characterize key aspects of these assessment approaches, and to discuss the advantages and disadvantages …

The Effect Of Coronal Prosthetic Alignment Changes On Socket Reaction Moments, Spatiotemporal Parameters, And Perception Of Alignment During Gait In Individuals With Transtibial Amputation, Hiroshi Hashimoto, Toshiki Kobayashi, Fan Gao, Masataka Kataoka, Kuniharu Okuda

Kinesiology and Health Promotion Faculty Publications

Introduction: The alignment of a prosthesis is clinically determined based on observations by clinicians and the subjective perception of amputees during gait. However, this process has been reported to be unreliable. Socket reaction moment has been reported to be significantly impacted by alignment changes, but the impact of these alignment changes on other gait parameters is unclear. The aim of this study was to investigate the effects of coronal alignment changes of a transtibial prosthesis on socket reaction moment, spatiotemporal parameters, and perceptions of alignment during gait in amputees.

Methods: Nine individuals with transtibial amputation participated in this study. Socket …

Human Body Motions Optimization For Able-Bodied Individuals And Prosthesis Users During Activities Of Daily Living Using A Personalized Robot-Human Model, Dimitrios Menychtas

USF Tampa Graduate Theses and Dissertations

Current clinical practice regarding upper body prosthesis prescription and training is lacking a standarized, quantitative method to evaluate the impact of the prosthetic device. The amputee care team typically uses prior experiences to provide prescription and training customized for each individual. As a result, it is quite challenging to determine the right type and fit of a prosthesis and provide appropriate training to properly utilize it early in the process. It is also very difficult to anticipate expected and undesired compensatory motions due to reduced degrees of freedom of a prosthesis user. In an effort to address this, a tool …

Autophagy And Aging: Maintaining The Proteome Through Exercise And Caloric Restriction, Kurt A. Escobar, Nathan H. Cole, Christine M. Mermier, Trisha A. Vandusseldrop

Faculty Articles

Accumulation of dysfunctional and damaged cellular proteins and organelles occursduring aging, resulting in a disruption of cellular homeostasis and progressive degen-eration and increases the risk of cell death. Moderating the accrual of these defunctcomponents is likely a key in the promotion of longevity. While exercise is knownto promote healthy aging and mitigate age‐related pathologies, the molecular under-pinnings of this phenomenon remain largely unclear. However, recent evidencessuggest that exercise modulates the proteome. Similarly, caloric restriction (CR), aknown promoter of lifespan, is understood to augment intracellular protein quality.Autophagy is an evolutionary conserved recycling pathway responsible for thedegradation, then turnover of cellular proteins …

Perspectives Of Caregivers And Volunteers On Stepping Stones For People With Dementia, Areum Han, Diane Brown

Health & Kinesiology Faculty Publications and Presentations

Rationale: Current knowledge in experiences and potential benefits of group-based activity programmes on people with dementia and their caregivers is inconsistent, depending on the quality of interventions. Lacking standardisation in the programme’s content and structure, therefore, requires research in a structured group-based activity programme with more details. Objectives: This study explored perspectives of spouses of people with dementia and older volunteers about Stepping Stones, involving a theme-based activity group and a support group. Methodology: Interpretative phenomenological analysis was used to analyse individual interview data with 12 people. Results: Findings suggest that (1) Stepping Stones promotes participation of people with dementia …

When Coordinating Finger Tapping To A Variable Beat The Variability Scaling Structure Of The Movement And The Cortical Bold Signal Are Both Entrained To The Auditory Stimuli, Steven Harrison, Michael Hough, Kendra K. Schmid, Boman Groff, Nicholas Stergiou

Journal Articles

Rhythmic actions are characterizable as a repeating invariant pattern of movement together with variability taking the form of cycle-to-cycle fluctuations. Variability in behavioral measures is atypically random, and often exhibits serial temporal dependencies and statistical self-similarity in the scaling of variability magnitudes across timescales. Self-similar (i.e. fractal) variability scaling is evident in measures of both brain and behavior. Variability scaling structure can be quantified via the scaling exponent (α) from detrended fluctuation analysis (DFA). Here we study the task of coordinating thumb-finger tapping to the beats of constructed auditory stimuli. We test the hypothesis that variability scaling evident …

Engage A Voice, Repress Fatigue; The Coincident Evolution Of Hominin Vocalization And A Metabolic Threshold, Galen A. Morton 9935238, Martin L. Morton

Shared Knowledge Conference

Physiologically self-protective mechanisms borne from hominin evolutionary history that increase survivability are not unknown to science. In reviewing exercise science literature regarding testing and assessment measures of subjects talking while exercising, a logical question has materialized: To what degree has evolution facilitated synchronization of comfortable oral communication with sustainable exercise intensity? An individual able to engage a voice, represses fatigue. The Talk Test, is a practical strategy whereby a subject deliberately speaks during an exercise protocol. It is a common tool in both kinesiology and clinical fields because it inherently identifies a pivotal metabolic threshold. The coincidence of comfortable ability …
