The Effects Of Exercise Intensity On Short-Term Memory, Karina Puentes, Joselynn Rivas Dec 2018

The Effects Of Exercise Intensity On Short-Term Memory, Karina Puentes, Joselynn Rivas

Kinesiology Student Research - Archive

The ability to recall information from the past is what is known as memory. There are two types of memory: short-term memory and long-term. Short-term is responsible for small temporary memory that can allocate past information within minutes and seconds. Long-term memory that is responsible to store large information for an extended period of time for months and years. Evidence shows that with increase exercise there is an improvement in memory retention/ cognitive function over time (Coles, 2008). People, more specifically college students, utilize their memory every single day, for example to recall an important note that the professor covered. …

INTRODUCTION: AdvoCare-Spark energy is a multi-nutrient supplement that incorporates ergogenic aids such as creatine and caffeine. The referred ergogenic aids are substances that enhance performance, and is one of the most studied research areas in athletic performance. Many supplements contain nutrients including water-soluble vitamins, metabolic by-products of nutrients, plant extracts, substances found in food (vitamin B6, creatine, caffeine) and are found in high amounts naturally in foods. Studies have shown that ingestion of caffeine pre-exercise can enhance endurance performance by decreasing the rate of perceived exertion. The combination of caffeine . and taurine in Advocare-Spark energy are both stimulants that …


Queen's College Step Test And Its Validity Of Vo(2max) Prediction On Young Healthy Females, Aaron Newland, Kevin Nguyen Dec 2018

Queen's College Step Test And Its Validity Of Vo(2max) Prediction On Young Healthy Females, Aaron Newland, Kevin Nguyen

Kinesiology Student Research - Archive

INTRODUCTION: The Queen's college step test (QCT) is a submaximal exercise test that is used to measure cardiorespiratory fitness. The test consists of 3 minutes of stepping up and down on a 15-inch step at a set rate of 22 steps/min. This test can also be used to estimate maximal oxygen consumption (VO2max). VO2max is an internationally accepted reference standard for assessing cardiorespiratory fitness (Shepard 1968). A lower maximal oxygen capacity is a strong predictor of cardiovascular disease. Despite claims that the QCT is a valid measure of VO2max, its validity in young healthy women has been contested (Chatterjee 2003). …


Development And Validation Of Hybrid Continuum/Structural Finite Element Model For Evaluating Foot And Ankle Biomechanics, Saif Alrafeek Dec 2018

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 …


Reporting Characteristics In Sports Nutrition, Conrad P. Earnest, Brandon M. Roberts, Christopher R. Harnish, Jessica L. Kutz, Jason M. Cholewa, Neil M. Johannsen Dec 2018

Reporting Characteristics In Sports Nutrition, Conrad P. Earnest, Brandon M. Roberts, Christopher R. Harnish, Jessica L. Kutz, Jason M. Cholewa, Neil M. Johannsen

Kinesiology

Purpose: To examine data reporting characteristics in sports nutrition. Methods: We examined 236 papers from ten journals published in 2016. The primary outcome was statistical variance associated with treatment (SD (correct) vs. SEM or CI). Secondary outcomes included the reporting of: (a) effect sizes (Y/N); (b) outcome prioritization (Y/N; primary, secondary, etc.) and (c) statistical variance relative to change from baseline (CI (correct) vs. SD or SEM). As tertiary/exploratory outcome, we examined whether authors stated a directed hypothesis. Statistical evaluation was performed using chi-square analyses. Results: We observed significant trends for all analyses (p < 0.001) and between category comparisons (p < 0.002). For the primary outcome, 128 (59%) articles correctly used SD to denote treatment variance, while 79 (36%) and 11 (5%) used SEM and CI, respectively. For secondary outcomes, 63 articles (29%) reported effect sizes, while 155 (71%) did not. Additionally, 188 articles (86%) did not prioritize outcomes, 134 articles (61%) stated no hypotheses and 40 (19%, out of 100) articles used CI to denote change scores vs. SD (19%, n = 41) and SEM (n = 10, 5%). Eight articles (4%) reported no variance terms. Conclusions: Overall, there are gaps regarding reporting in sports nutrition. Editors, journal publishers, and the field of exercise science alike should consider these outcomes and provide editorial staff, reviewers and authors with more concrete guidelines.

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 Dec 2018

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 Dec 2018

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 …

Human Body Motions Optimization For Able-Bodied Individuals And Prosthesis Users During Activities Of Daily Living Using A Personalized Robot-Human Model, Dimitrios Menychtas Nov 2018

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 …

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 …

Faculty Scholarship

Background

Augmenting fat oxidation is a primary goal of fitness enthusiasts and individuals desiring to improve their body composition. Performing aerobic exercise while fasted continues to be a popular strategy to achieve this outcome, yet little research has examined how nutritional manipulations influence energy expenditure and/or fat oxidation during and after exercise. Initial research has indicated that pre-exercise protein feeding may facilitate fat oxidation while minimizing protein degradation during exercise, but more research is needed to determine if the source of protein further influences such outcomes.
