The Effects Of Two Different Resistance Training Protocols With Similar Volume On Muscular Strength, Muscle Thickness, And Fat-Free Mass, Cory Worthey

Theses and Dissertations

The manipulation of exercise volume, intensity, and order is associated with producing different musculoskeletal changes. These resistance training program variables affect mechanical tension and metabolic stress associated with resistance training, therefore affecting strength and hypertrophic outcomes. PURPOSE: The purpose of this study was to examine the effects of two different volume-equated total body exercise protocols over 9 weeks using compound exercises on muscular strength, muscle thickness, and fat-free mass. METHODS: Eight well-trained men were randomly assigned to a hypertrophy-style protocol (HG) performing 3 sets of 10 repetitions with 90 seconds rest between sets (n = 4) or a strength-style protocol …

Understanding Flow Occurrence: Contributions From The 2x2 Achievement Goal Framework, Devan Antczak

Theses and Dissertations

Flow is often described as an optimal state, a rewarding experience, and highly motivating. Yet, much of how flow occurs is not understood. Multiple factors have been found to be antecedents of flow, one of which is motivation. The purpose of this study was to determine if variations in motivation according to the 2x2 achievement goal theory resulted in differences in occurrence of flow. An experimental design was utilized. Currently training male and female runners (N=60, ages 18-44 years), were randomly assigned to one of the four different achievement goal groups and reported on the level of flow experienced during …

Fission–Fusion Species Under Restricted Living Conditions: A Comparative Study Of Dyadic Interactions And Physical Proximity In Captive Bonobos And Bornean Orangutans, Dorothee Classen, Stefanie Kiessling, Madhur Mangalam, Werner Kaumanns, Mewa Singh

Journal Articles

The present study investigates how the 'fission–fusion-adapted' bonobos and Bornean orangutans manage social relationships when kept under permanent group-living conditions. Our results showed that the bonobos and orangutans did not differ in the overall frequency of dyadic interactions. The orangutans evidently realized a potential to interact with partners, which on a surface did not differ from what was found in the bonobos. However, the bonobos spent more time on sociopositive interactions, especially on grooming and sit in contact, whereas the orangutans agonistically interacted with each other more often. Though frequencies of approaching were similar between the two species, orangutans actively …

Associations Between Mobility, Cognition And Callosal Integrity In People With Parkinsonism, Brett W. Fling, Marian L. Dale, Carolin Curtze, Katrijn Smulders, John G. Nutt, Fay B. Horak

Journal Articles

Falls in people with parkinsonism are likely related to both motor and cognitive impairments. In addition to idiopathic Parkinson's disease (PD), some older adults have lower body parkinsonism (a frontal gait disorder), characterized by impaired lower extremity balance and gait as well as cognition, but without tremor or rigidity. Neuroimaging during virtual gait suggests that interhemispheric, prefrontal cortex communication may be involved in locomotion, but contributions of neuroanatomy connecting these regions to objective measures of gait in people with parkinsonism remains unknown. Our objectives were to compare the integrity of fiber tracts connecting prefrontal and sensorimotor cortical regions …

The Effects Of Caffeine On Reaction Time Of Two Neurocognitive Tests, Kyle Petit

Theses and Dissertations

Context: A concussion is defined as a traumatically induced transient disturbance of the brain caused by a biomechanical force. These problematic injuries can prevent athletes from participating in physical activity for a number of days, weeks, or even months. Caffeine is known for improving mental alertness in everyday tasks and is found in many popular drinks such as, coffee, tea, energy shots, and even soda. Due to its increase in memory, mental alertness, and concentration, caffeine could potentially be utilized to improve the outcomes of post-concussion neurocognitive testing. This improvement would allow athletes to return to play before they have …

This study aimed to: (1) examine the factor structure and composition of sedentary-derived protection motivation theory (PMT) constructs and (2) determine the utility of these constructs in predicting general and leisure sedentary goal intention (GI), implementation intention (II), and self-reported SB. Sedentary-derived PMT (perceived severity, PS; perceived vulnerability, PV; response efficacy, RE; self-efficacy, SE), GI, and II constructs, and a modified SB questionnaire were completed by undergraduate students (n = 596). SE was broken into …

Effects Of Three-Times Daily Diet Soda Consumption For One Week On The Composition Of The Gut Microbiome In Healthy Young Adults, Jenna Abdelhadi, Domenica Simone, Charles Hadley King, Raja Mazumder, Keith A. Crandall, Allison C. Sylvetsky-Meni

GW Research Days 2016 - 2020

Epidemiologic studies report associations between artificial sweetener (ASW) consumption and metabolic abnormalities, yet well-designed human intervention studies in humans are limited. Given that ASW contain no or few calories, one potential mechanism through which ASW may influence metabolic risk is through altering the gut microbiota. As alterations in the gut microbiota are known to be implicated in the development of metabolic disease, the purpose of this study was to investigate the effects of one week of three times daily diet soda (with ASW) consumption on the gut microbiota in healthy college students. We hypothesized that participants randomized to consume diet …

The Effect Of Whole Body Vibration On Exercise-Induced Muscle Damage And Delayed-Onset Muscle Soreness, Ryan Darin Magoffin

Theses and Dissertations

Current scientific evidence suggests that when whole body vibration (WBV) is used as a warm-up prior to performing eccentric exercise, delayed-onset muscle soreness (DOMS) is mitigated and strength loss recovers faster. These benefits were observed primarily in nonresistance-trained individuals. The aim of this study was to determine if WBV could mitigate soreness and expedite strength recovery for resistance-trained individuals when used as a warm-up prior to eccentric exercise. Thirty resistance-trained males completed 300 maximal eccentric contractions of the quadriceps after warming up with (WBV) or without (CON) WBV. Both CON and WBV experienced significant isometric (27.8% and 30.5%, respectively) and …

Perception-Action Mutuality Does Not Obviate Emergence Or The Animal’S Active Role In The Perceptual Act, Dobromir Dotov

Journal Articles

Open peer commentary on the article “Perception-Action Mutuality Obviates Mental Construction” by Martin Flament Fultot, Lin Nie & Claudia Carello. Upshot: The main goal of this commentary is to make more discriminative the comparison between enactive and ecological theories of perception. Emergence at the level of the animal-environment system might be playing the role attributed to mental construction in basic perceptual processes. If correct, this would render some forms of enactivism compatible with the theoretical tenets of the target article.

Acute Changes In Running Mechanics Across Footwear With Various Heel-To-Toe Height Differences, Daniel C. Moody

Theses and Dissertations

There are many different types of footwear available for runners in today's market. Many of these shoes claim to improve a runner's efficiency by altering their stride mechanics. Minimalist footwear claims to aid runners in running more on their forefeet whereas more traditional footwear provides more cushioning specifically for a heel-first landing. The purpose of this research was to determine if runners who were accustomed to running in traditional footwear would acutely alter their running biomechanics when they ran barefoot or in various types of minimalist footwear. Twelve subjects, who were accustomed to running in traditional 12 mm heel/toe differential …

Health Sciences & Kinesiology: Faculty Publications

Background

Athletes have been shown to exhibit better balance compared to non-athletes (NON). However, few studies have investigated how the surface on which athletes train affects the strategies adopted to maintain balance. Two distinct athlete groups who experience different types of sport-specific balance training are stable surface athletes (SSA) such as basketball players and those who train on unstable surfaces (USA) such as surfers. The purpose of this study was to investigate the effects of training surface on dynamic balance in athletes compared to NON.

Methods

Eight NON, eight SSA, and eight USA performed five 20-s trials in each of …

A Comparison Of Blood Flow Changes In Tissues Treated With Therapeutic Ultrasound And Electrical Stimulation, Ryanne Mcdaniel

Theses and Dissertations

Context: Therapeutic ultrasound and electrical stimulation both claim to achieve many effects on the body, one of which is increasing blood flow in tissues. Research on electrical stimulation in regards to blood flow has shown both increased and decreased blood flow, due to the electrode placement and the muscular contractions elicited during the treatment, while research on therapeutic ultrasound has provided mixed results, some suggesting that increased blood flow is seen only with intolerable treatment intensities for the patients. The two treatments have not been previously compared in the same study. Objective: To compare radial artery blood flow following therapeutic …

Manual Therapy Effects On Low Back Pain, Shelby Dale

Theses and Dissertations

Context: Instrument assisted soft tissue mobilization (IASTM), specifically the Graston Technique® (GT), uses six stainless steel instruments to mobilize soft tissue by exploiting the principles of transverse friction massage. Muscle energy technique (MET) is an active technique where the patient contracts specific muscles, when instructed, in a specific direction against a distinctly executed counterforce from the clinician. MET is used to mobilize restricted joints, strengthen weak muscles, reduce pain, stretch tight muscles and fascia, increase range of motion (ROM) and improve circulation.

Objective: The purpose of this study was to compare MET in combination with GT to MET in isolation …

A Systematic Review Of Empathy Development In Medical Education, Sandra H. Sulzer, Claire Wendland, Noah Feinstein

Kinesiology and Health Science Faculty Publications

Context Empathy in doctor–patient relationships is a familiar topic for medical scholars and a crucial goal for medical educators. Nonetheless, there are persistent disagreements in the research literature concerning how best to evaluate empathy among physicians, and whether empathy declines or increases across medical education. Some researchers have argued that the instruments used to study ‘empathy’ may not measure anything meaningful to clinical practice or patient satisfaction. Methods We performed a systematic review to learn how empathy is conceptualised in medical education research. We examined how researchers define the central construct of empathy and what they choose to measure, and …

Effects Of Transcutaneous Electrical Nerve Stimulation On Quadriceps Activation And Walking Mechanics In Patients With Anterior Knee Pain, Brian Wiseman, J. Ty Hopkins

Journal of Undergraduate Research

More than ten million people in the U.S. suffer from knee pain, and one in every two people may develop chronic knee pain by age 85.³ Knee pain is also 1 of 5 leading causes of disability among adults, and alters muscle function and walking mechanics, which in turn, decreases quality of life.⁶ To alleviate the effects of knee pain and its consequences, transcutaneous electrical nerve stimulation (TENS) is often used to decrease perceived pain⁵ and increase quadriceps activation.⁷ However, it is unclear whether these benefits could offer potential improvement for walking mechanics. Therefore, the purpose …

Morphology Of Human Myoblasts In Cultured Muscle Cells By The Novel Small Molecule Sgi, Ryan Matekel, Robert Hyldahl

Journal of Undergraduate Research

Muscle wasting is a symptom of cancer, AIDS, renal failure, heart failure, aging, prolonged bed rest, and has been seen in rodent models for burn, and kidney disease (Han, 2013). Muscle wasting negatively impacts quality of life by decreasing functional independence and increasing morbidity and mortality (Anker, 1997). Muscle wasting is an especially serious issue given that the body weight of an average human is 40-50 percent skeletal muscle (Han, 2013). Myostatin is a protein that negatively regulates muscle mass and is primarily expressed within skeletal muscle (Lee & McPherron, 2001). Genetic studies have shown that inhibition of myostatin signaling …

Effect Of Myostatin Pathway Inhibition On Fibroblast Activity Using A Novel Small Molecule, Seth Hampton, Dr. Robert Hyldahl

Journal of Undergraduate Research

Fibroblasts play a key role in repairing injured tissue by secreting collagen and growth factors into the tissue. In states of disease and overuse, fibroblast activity can become overly abundant and can lead to skeletal muscle fibrosis, decreasing strength and muscle elasticity. This fibrotic condition can lead to muscle wasting disorders, such as muscular dystrophies, that severely decrease the length and quality of life. Previous studies have shown that the TGF-beta signaling family directly increases fibroblast proliferation. It has also been shown that inhibition of myostatin, a member of the TGF-beta family, reduces symptoms of muscular dystrophies and decreases fibrosis. …

Evidence For Regulatory T Cell In Skeletal Muscle Repair, Amanda Gier, Robert Hyldahl

Journal of Undergraduate Research

Testing multiple immunohistochemistry protocols, I was unsuccessful at identifying Tregulatory cells in human skeletal muscle samples. A total of 5 months was dedicated to this original project before I was reassigned to look into the presence of CD8+ cells in skeletal muscle. The new project proved to be fruitful as I was able to confidently identify CD8+ cells and analyze their presence in the process of skeletal muscle repair. Furthermore, the data I collected has be incorporated into a paper Dr. Robert Hyldahl is currently working on titled “Skeletal muscle inflammation following repeated bouts of lengthening contractions in humans.”

Foot Strike Angle Changes During Shod, Minimalist, And Barefoot Running, And Correlation To Injury, Ani Henriksen, Dr. Sarah Ridge

Journal of Undergraduate Research

Running is a popular form of exercise. With high incidence of injury, runners are always looking for the next cure to stay injury free. Many webpages offer conflicting advice about shoes and foot strike. Although recommendations vary, barefoot running and use of minimalist shoes has increased. With the change in footwear, many runners have reported injuries from improper technique and repetitive loading. With the use of current technology we analyzed movements of the foot ignored by other studies. This project analyzed foot strike movement in the frontal plane to help us better understand the ideal foot strike technique for running …

Volumetric Flow Imaging Reveals The Importance Of Vortex Ring Formation In Squid Swimming Tail-First And Arms-First, Ian K. Bartol, Paul S. Krueger, Rachel A. Jastrebsky, Sheila Williams, Joseph T. Thompson

Biological Sciences Faculty Publications

Squids use a pulsed jet and fin movements to swim both arms-first (forward) and tail-first (backward). Given the complexity of the squid multi-propulsor system, 3D velocimetry techniques are required for the comprehensive study of wake dynamics. Defocusing digital particle tracking velocimetry, a volumetric velocimetry technique, and high-speed videography were used to study arms-first and tail-first swimming of brief squid Lolliguncula brevis over a broad range of speeds [0-10 dorsal mantle lengths (DML) s^-1) in a swim tunnel. Although there was considerable complexity in the wakes of these multi-propulsor swimmers, 3D vortex rings and their derivatives were prominent reoccurring features …

Mastoid Vibration Affects Dynamic Postural Control During Gait, Jung Chien, Mukul Mukherjee, Nicholas Stergiou

Journal Articles

Our objective was to investigate how manipulating sensory input through mastoid vibration (MV) could affect dynamic postural control during walking, with and without simultaneous manipulation of the visual and the somatosensory systems. We used three levels of MV (none, unilateral, and bilateral) via vibrating elements placed on the mastoid processes. We combined this with the six conditions of the Locomotor Sensory Organization Test (LSOT) paradigm to challenge the visual and somatosensory systems. We hypothesized that MV would affect both amount and temporal structure measures of sway variability during walking and that, in combination with manipulations of the visual and the …

A Randomized Controlled Trial Comparing Rehabilitation Efficacy In Chronic 1 Ankle Instability, Cynthia J. Wright, Shelley W. Linens, Mary Spencer Cain

Health Sciences Faculty Scholarship

There is minimal patient-oriented evidence regarding the effectiveness of interventions targeted to reduce symptoms associated with chronic ankle instability (CAI). Additionally, clinicians aiming to prioritize care by implementing only the most effective components of a rehabilitative program have very little evidence on comparative efficacy. The objective of this research report is to assess the comparative efficacy of two common ankle rehabilitation techniques [wobble board (WB) balance training and ankle strengthening using resistance tubing (RT)] using patient-oriented outcomes.
