Research And Critical Thinking : An Important Link For Exercise Science Students Transitioning To Physical Therapy, Harvey W. Wallmann, Donald L. Hoover

International Journal of Exercise Science

Int J Exerc Sci 5(2) : 93-96, 2012. Critical thinking skills are increasingly necessary for success in professional health care careers. Changes in the contemporary healthcare system in the United States arguably make these critical thinking skills more important than they have ever been, as clinicians are required on a daily basis to evaluate multiple bits of information about patients with multiple-systemic health concerns and make appropriate treatment decisions based on this information. We believe the IJES, with its emphasis on engaging undergraduate and graduate students in research and scholarly activity, is a valuable resource for promoting the higher-order critical …

A Biomechanical Analysis Of The Gymnastics Cartwheel Using Dartfish Motion Analysis Software, Keilea Bullard

Undergraduate Research Conference

The biomechanical analysis required videotaping two subjects performing the cartwheel to the best of their ability. Strict protocols were followed to ensure the analysis was accurate. In order to measure distances in the Dartfish program, an object of known length had to be recorded. Subjects were asked to hold a scaling rod for ten seconds before beginning their trials. Subjects recorded four trials each and all data was imported into the Dartfish program. Average trials for both subjects were chosen to be analyzed extensively for strengths, weaknesses and most importantly the overall biomechanics of the cartwheel. The subjects’ video was …

Analysis Of A Kinetic Multi-Segment Foot Model. Part Ii: Kinetics And Clinical Implications, Dustin A. Bruening, Kevin M. Cooney, Frank L. Buczek

Faculty Publications

Kinematic multi-segment foot models have seen increased use in clinical and research settings, but the addition of kinetics has been limited and hampered by measurement limitations and modeling assumptions. In this second of two companion papers, we complete the presentation and analysis of a three segment kinetic foot model by incorporating kinetic parameters and calculating joint moments and powers. The model was tested on 17 pediatric subjects (ages 7–18 years) during normal gait. Ground reaction forces were measured using two adjacent force platforms, requiring targeted walking and the creation of two sub-models to analyze ankle, midtarsal, and 1st metatarsophalangeal joints. …

Gait Variability Measures Reveal Differences Between Multiple Sclerosis Patients And Healthy Controls, Jeffrey P. Kaipust, Jessie M. Huisinga, Mary Filipi, Nikolaos Stergiou

Journal Articles

The purpose of this study was to determine the differences in gait variability between patients with multiple sclerosis (MS) and healthy controls during walking at a self-selected pace. Methods: Kinematics were collected during three minutes of treadmill walking for 10 patients with MS and 10 healthy controls. The Coefficient of Variation (CoV), the Approximate Entropy (ApEn) and the Detrended Fluctuation Analysis (DFA) were used to investigate the fluctuations present in stride length and step width from continuous strides. Results: ApEn revealed that patients with MS had significantly lower values than healthy controls for stride length (p < .001) and step width (p < .001). Conclusions: ApEn results revealed that the natural fluctuations present during gait in the stride length and step width time series are more regular and repeatable in patients with MS. These changes implied that patients with MS may exhibit reduced capacity to adapt and respond to perturbations during gait.

Evidence-Based Practice For The Athletic Training Profession, Cailee Elizabeth Welch

Human Movement Studies & Special Education Theses & Dissertations

As evidence-based practice (EBP) becomes a necessity in athletic training, it is essential to recognize current barriers and modes of accessibility to information for enhancement of clinical decision-making. Furthermore, the effectiveness of educational interventions (EI) to enhance knowledge of EBP concepts must be investigated. The aim of Project I was to assess attitudes and beliefs, perceived barriers, and accessibility to resources of EBP among athletic trainers (AT). Project II was designed to investigate the effect of an EI on enhancing AT's knowledge of EBP concepts. Project III explored ATs' experiences of the EI and whether it elicited changes within their …

The Effects Of Acute Hypoxia On Marksmanship, Chelsea Mary Moore

Human Movement Studies & Special Education Theses & Dissertations

Expeditionary warfighters in the military have the responsibility of being ready to deploy on short notice to any part of the world and be able to effectively complete their mission even if deployed to altitude. Studies demonstrate that altitude can significantly effect heart rate, ventilation rate, arterial oxygen saturation (SaO2) and cognition. Decrements in these areas could lead to a reduction in shooting accuracy. Only two studies have looked at the effects of marksmanship at various altitudes and their results are inconclusive. This study evaluated the effects of acute hypoxia on marksmanship and the effect of a physical exertion task …

The Influence Of Interlimb Differences On Anterior Cruciate Ligament Injury Risk Factors In Female Collegiate Soccer Athletes, Eric Kevin Greska

Human Movement Studies & Special Education Theses & Dissertations

Female collegiate soccer athletes suffer anterior cruciate ligament (ACL) injuries at a rate of 0.31 per 1000 athlete-exposures, with 67% of injuries expected to be from a non-contact mechanism. As well, previous studies have demonstrated dissimilarity in non-contact ACL injuries relative to dominant and non-dominant legs; with the non-dominant leg being the involved side in 48-67% of reported incidents. The aim of this study was to examine lower extremity neuromechanics relative to leg dominance during an unanticipated sidestep cutting task, with differing states of fatigue and training.

Twenty female collegiate soccer players performed three valid trials for both the dominant …

Human Movement Studies & Special Education Theses & Dissertations

The rise in prevalence and incidence of type 2 diabetes mellitus (T2D) in the developing world continues unabated. Current treatment strategies, however, fall short of achieving optimal glycemic control. The aim of project I was to investigate the effect of an acute bout of a yogic breathing exercise on heart rate variability (HRV) in individuals with T2D. Project II was designed to assess the effectiveness of the neurohormone melatonin in lowering short- and long-term glucose levels, lipids and oxidative stress in T2D. Project III investigated the differential effects of two different styles of aerobic exercise on postprandial glycemia, mood and …

Analysis Of A Kinetic Multi-Segment Foot Model. Part I: Model Repeatability And Kinematic Validity, Dustin A. Bruening, Kevin M. Cooney, Frank L. Buczek

Faculty Publications

Kinematic multi-segment foot models are still evolving, but have seen increased use in clinical and research settings. The addition of kinetics may increase knowledge of foot and ankle function as well as influence multi-segment foot model evolution; however, previous kinetic models are too complex for clinical use. In this study we present a three-segment kinetic foot model and thorough evaluation of model performance during normal gait. In this first of two companion papers, model reference frames and joint centers are analyzed for repeatability, joint translations are measured, segment rigidity characterized, and sample joint angles presented. Within-tester and between-tester repeatability were …

Estimating Vo2max Using A Personalized Step Test, Catherine Webb

Theses and Dissertations

The purpose of this study was to develop a personalized step test and a valid regression model that used non-exercise data and data collected during the step test to estimate VO2max in males and females 18 to 30 years of age. All participants (N= 80) successfully completed a step test with the starting step rate and step height being determined by the self-reported perceived functional ability (PFA) score and participant's height, respectively. All participants completed a maximal graded exercise test (GXT) to measure VO2max. Multiple linear regression analysis yielded the following equation (R = 0.90, SEE = 3.43 mL/kg/min): 45.938 …

Evaluation Of Transfer Technologies To Preserve Shoulder Function In Sci, Karen Michelle Mann

USF Tampa Graduate Theses and Dissertations

This study investigated a series of independent unassisted and device-assisted transfers from a wheelchair to vehicle mock-up and vice versa while simultaneously capturing kinematic, kinetic and electromyographic (EMG) data of impaired volunteers. The study provides a venue for observation and evaluation of upper extremity (UE) joint stresses, muscular force and functional demands associated with transfers in persons with spinal cord injury (SCI) to ultimately prevent UE injury, minimize excessive stress, preserve functionality and limit pain. If people with SCI lose function of their UEs, due to pain and/or degeneration, they must then rely on others for everyday tasks.

Yoga has been around for centuries and has steadily increased in popularity in the West through the years, but this mind-body-spirit practice has had very little research conducted perceived intensities. PURPOSE: to assess heart rate (HR) and rating of perceived exertion (RPE) of those participating in yoga classes. It is hypothesized that as HR increases, there will also be in increase in RPE. It is also hypothesized that those taking yoga classes have goals of flexibility and stress …

Preliminary Analysis Of The Feasibility And Effectiveness Of Whole Body Vibration As A Therapeutic Intervention In A Skilled Nursing Facility, Kai Williams, Chris Goldstraw, Sheila Kellagher, Steven Tham, William E. Amonette

International Journal of Exercise Science: Conference Proceedings

Skeletal muscle sarcopenia results in loss of strength, power and functional capabilities leading to decreased independence and an increased reliance on the healthcare system. Exercise is an effective countermeasure to age related loss of muscle, but may be difficult in elderly patients with complex functional limitations. Whole body vibration (WBV) is a novel tool used to stimulate the neuromuscular system; research indicates it may improve strength, power, and balance in many populations. Purpose: The purposes of this study were to determine if WBV training is feasible in a skilled nursing facility and if standard of care (SOC) with augmented WBV …

Timed Up-And-Go Scores Are Associated With Balance But Not Lower-Extremity Force Production In Elderly Skilled Nursing Facility Patients, Christopher Barnett, Kai Williams, Chris Goldstraw, Sheila Kellagher, Steven Tham, William E. Amonette

International Journal of Exercise Science: Conference Proceedings

Aging is associated with numerous deleterious muscular, skeletal, and neurologic adaptations that may result in functional performance decrements. These decrements are accelerated during periods of unplanned physical inactivity (e.g. hospitalization). Reductions in gait velocity are well documented in the elderly and may result from fear of falling, poor balance, or inability to accelerate because of reduced ground reaction force capabilities. Purpose: To determine if timed up-and-go scores were related to balance or lower extremity force production in skilled nursing facility patients. Methods: Data were collected on 40 patients (77.1±1.4y; 164.2±1.7cm; 75.3±3.3 kg) in an inpatient skilled nursing facility. The 15 …

The Impact Of Physiologic Reductions In Blood Pressure Upon Oxygen Uptake During Moderate Intensity Leg Cycling, Cory L. Butts, Paul Mcdonough, David Keller, Mitchel Samels, Davor Krnjajic

International Journal of Exercise Science: Conference Proceedings

INTRODUCTION: Control of oxygen uptake (VO2) during the rest-to-exercise transition is thought to be dominated by intracellular processes rather than oxygen delivery. However, large changes in arterial pressure (i.e., supraphysiologic) have been shown to alter VO₂ and its kinetics. Importantly, no studies have investigated the consequence of physiologic alterations in blood pressure on VO₂ and its kinetics during exercise in humans. PURPOSE: The aim of this preliminary study was to assess the effect of modest reductions in MAP achieved via neck suction upon Vo₂ across the rest-exercise transition, to test the hypothesis that physiologic reductions in arterial …
