Sensitivity Of The Vasoactive Range In Determining Aerobic Fitness, Preston L. Bell

Honors Theses

Previous work has demonstrated a direct relationship between aerobic fitness and indices of vasodilatory function (i.e., Flow-mediated Dilation; FMD). Importantly, recent evidence suggests that vasoconstrictor function to reductions in blood flow (i.e., Low-Flow Mediated Constriction; L-FMC), as well as during sympatho-excitation (i.e., Cold Pressor Test), may compliment the FMD measure, thus, providing an overall range of vascular responsiveness. The purpose of this thesis project was to test the hypothesis that vasoactive range indices (peak vasodilation + nadir vasoconstriction) are sensitive to aerobic fitness levels in healthy young men. Fourteen males (age: 22±4 yrs) were recruited, and divided evenly into a …

Effects Of A Virtual Training Partner On Cycling Time Trial Performance In Recreationally Active Females, Janae L. Myers

Celebrating Scholarship & Creativity Day (2011-2017)

Introduction. Fatigue is a result of physiological and psychological limits. Associative thoughts (thoughts of physical sensations) and dissociative thoughts (thoughts not regarding physical sensations) compete for attentional focus during exercise and can influence exercise performance and fatigue. Distractions during exercise, such as watching TV or interactive exercise, increase dissociative thoughts and reduce rate of perceived exertion (RPE). Limited research exists regarding the effects of a virtual training partner on exercise performance and fatigue.

Purpose. To examine whether the use of a virtual training partner (ghost) will improve performance by increasing dissociative thoughts. We hypothesized that the use of a ghost …

Concussions, Why They Go Unreported, Drake Matuska

Celebrating Scholarship & Creativity Day (2011-2017)

Introduction: In the world today, concussions are a major health risk in sports and many other physically demanding activities. Every day, we see former athletes who have experienced multiple concussions complain of cognitive impairment and memory loss. It is the risk every athlete takes when they participate in a sport they love; however, when an individual plays through a concussion that is when a line is crossed. People playing through a concussion lead to the foundation of this study, which is to find out why individuals play through their concussions, why they fail to report, and the core cognitive reasons. …

Assessment Of Anti-Saccades Within 24 To 48 Hours Post-Concussion, Nathan D'Amico

GS4 Student Scholars Symposium

INTRODUCTION: Approximately 90% of concussions involve oculomotor impairment, with saccadic eye movement deficits being the most prominent oculomotor impairment. Saccades are rapid eye movements that bring a fixed point or area of interest into the center of sight and are important for safely navigating through the environment. Anti-saccades are saccadic eye movement deficits that involve a reflexive, involuntary saccade away from a fixed point or area of interest. Assessments of anti-saccades may provide a fast, accurate, and reliable way to screen for concussion. However, little research quantitatively explores anti-saccades post-concussion.

PURPOSE: To investigate anti-saccades between NCAA Division I athletes 24-48 …

Identification Of Kinematic And Kinetic Injury Risk Predictors In Division I Football Athletes, Corbin M. Rasmussen, Guilherme M. Cesar, Shinya Takahashi

UCARE: Research Products

biomechanical patterns and insufficiencies that may influence risk of ligamentous injury, such as an anterior cruciate ligament (ACL) tear. One kinematic pattern that has been identified as detrimental to ACL integrity is frontal plane knee collapse (valgus) during jumping and landing tasks.1 Inter-limb differences in force generation have also been connected to the occurrence of lower extremity injury.2 It is not known, however, whether these patterns contribute to the occurrence of lower extremity (LE) non-contact soft-tissue injury. The counter-movement vertical jump (CMVJ) is one way to simultaneously screen for knee collapse and asymmetrical force production patterns. This method was therefore …

Examining The Relationship Between Training Environment And Muscle Dysmorphia Symptoms, Michelle F. Bubnis

Masters Theses & Specialist Projects

Muscle Dysmorphia (MD) is characterized by preoccupation with muscularity. Although there is a growing body of research concerning MD, there is a lack of research concerning the potential role exercise training environment has on the clinical features of MD. The purpose of this study was to compare MD symptomology in traditional strength-trained (TRAD) individuals to individuals training in communal high intensity functional training environments (HIFT). Participants were recruited from both types of facilities. Participants (N=376) completed online (Qualtrics) demographics survey and Muscle Dysmorphia Inventory (MDI). One-way ANOVA compared the effect of training environment on MDI scores among HIFT, TRAD, both …

The purpose of this study was to examine the effects of a commercially available thermogenic fat loss supplement on RMR and hemodynamic variables in healthy, resistance trained males.

Methods: Ten resistance-trained male participants (29 ± 9 years; 178 ± 4 cm; 85.7 ± 11 kg, and BMI = 26.8 ± 3.7) volunteered to participate in this randomized, double-blind, placebo controlled cross-over study. Participants underwent two testing …

Ingestion Of A Nutritional Supplement Pre-Workout Will Increase Exercise Time-To-Fatigue, Allison D. Bloomer, Beena R. Chemmanchery, Rachel Liebowitz, Hannah M. Zalaker

Kinesiology 288

Everyone fatigues at the end of an intense exercise bout. However, previous research has indicated that ingestion of a mixed nutrient supplement one hour pre-exercise will increase exercise time-to-fatigue¹. For this experiment, four females between the ages 20-50 participated in a controlled pilot study. Exercise was performed using a row machine, where time- to-fatigue was measured from a baseline of 80% max HR (220 minus age). The nutrient supplement was ingested 1 hour pre-rowing and contained 30g of protein, 5g carbohydrate, and 3g of fat. Results showed that pre-exercise ingestion of a mixed protein supplement did increase row time-to-fatigue.

Blood Glucose Levels And High Intensity Exercise With Respect To Meal Timing, Gabriel S. Barnett, Bryan A. Frees

Kinesiology 288

The research conducted was about monitoring blood glucose levels with exercise with respect to meal timing. It has been hypothesized that with short bouts of high intensity exercise, one can raise their blood glucose levels because in acute response to high intensity exercise. Previous research has shown that with long bouts of exercise while fasting you can lower blood glucose levels. This study is testing the meal timing from fasting to right before the exercise and also eating one and two hours before combined with a 50 minute moderate to high intensity workout, keeping the heart rate in zones 3- …

Average Strength Comparison Between Males And Females In Weight Training, Jaz M. Kates, Josh D. Payne

Kinesiology 288

In our research we wanted to look at the comparison in strength between males and females in weight training. In recent research, we were able to look at sex stereotypes when considering sport and exercise. A particular study stated that, “… sport is still viewed as a “male area” in western countries, and recent reports indicate that boys/men still participate more in sports, compared to girls/women” (Boiche 1). So, we took three males and three females from Parkland College to test our hypothesis. Before beginning our research, our hypothesis was that males would be higher in all categories. In other …

Effects Of Combination Ice And Compression Socks On Resting Calf Blood Flow In Trained Male Athletes, Michael John Hudock Jr.

Honors Theses

Compression socks are common tools that are utilized in the realm of athletics. The purpose of the compression is to increase blood flow to the lower extremities, thereby increasing oxygen and energy sources needed for increased skeletal muscle function and/or recovery. Recently, a product has been marketed that combines the compression element with cryotherapy, the goal being increased blood flow to the lower extremities while reducing inflammation post-workout to quicken recovery. However, to our knowledge, direct measures of blood flow using this type of product have not been performed. Thus, this study looks at the effects of compression with and …

The Effects Of Fitness Level And Sex On Epoc Following High Intensity Interval And Moderate Intensity Aerobic Exercise, Rachel Lauren Simmons

Human Movement Studies & Special Education Theses & Dissertations

In the past few years, much attention has been directed toward shorter-duration vigorous intensity aerobic exercise as opposed to longer-duration moderate intensity exercise. There is conflicting evidence as to whether vigorous exercise can result in a greater excess post-exercise oxygen consumption (EPOC) and thus more calories burned when compared to moderate continuous exercise performed for a longer duration. In addition, the literature contains a dearth of information isolating and investigating male and female response to these exercises, as well as fit and unfit subjects. The purpose of this study was to quantify EPOC following moderate intensity aerobic exercise (MOD) and …

The Effects Of A Single-Dose Thermogenic Supplement On Resting Metabolic Rate And Hemodynamic Variables In Healthy Females - A Randomized, Double-Blind, Placebo-Controlled, Cross-Over Trial, Bill I. Campbell, Gina Zito, Ryan Colquhoun, Nicholas Martinez, Kristina Kendall, Laura Buchanan, Matt Lehn, Mallory Johnson, Courtney St. Louis, Yasmin Smith, Brad Cloer, Allison Pingel

Physical Education and Exercise Science Faculty Publications

Background: Recent investigations have identified that commercially available dietary supplements, containing a combination of thermogenic ingredients, can increase resting metabolic rate (RMR). Thermogenic dietary supplements can have a positive influence on RMR, but the magnitude can vary based on the active ingredient and/or combination of active ingredients. Additionally, further safety evaluation is needed on multi-ingredient supplements that contain caffeine, due to its potential effect on heart rate (HR) and blood pressure (BP). The purpose of this study was to examine the effects of a commercially available dietary supplement on RMR and hemodynamic variables in healthy females.

Methods: 13 female participants …
