The Physiological Responses To Cycling Stress., Moriah Larsen 2016 Northern Arizona University

The Physiological Responses To Cycling Stress., Moriah Larsen

Skyline - The Big Sky Undergraduate Journal

Background: As the intensity of exercise increases, the risk of incidences for exertional heat illness (EHI) continues to climb. The National Athletic Trainers Association (NATA) has set an official position statement; stating a “gold standard” for obtaining core body temperature is via rectal thermometry. It has been reported that other field-expedient methods of obtaining core body temperature (oral, axillary, tympanic, temporal) are invalid or unreliable sources after intense exercise in hot temperature regions. Purpose: To determine if a relationship exists between rectal temperature measurements and tympanic temperature measurements during intensive long bouts of exercise. Design: Controlled Laboratory Study. Setting: Human ...

Hip Flexor Extensibility And Its Correlation To Hip Hyperextension And Lower Back Pain In Dancers, Tessa Richards

Skyline - The Big Sky Undergraduate Journal

The goal of this research was to measure the correlation between hip flexor extensibility, arabesque height, and lower back pain; specifically, whether a tight iliopsoas group restricts range of motion and correlates with lower back pain in dancers. Through a series of non-invasive measurements, the rectus femoris and iliopsoas group were tested for range of motion and general extensibility. The measurements were as follows: Patrick’s Test, Thomas’s Test, Modified Thomas Test, and prone hip hyperextension. Each subject also completed a pre-screening form to assess degree of lower back pain. The outcomes of the measurements were analyzed to find ...


The Role Of Osteocyte Estrogen Receptor Beta (Erβ) In Regulating The Skeletal Response To Mechanical Loading, Julia P. Townsend, Russell P. Main 2016 Purdue University

The Role Of Osteocyte Estrogen Receptor Beta (Erβ) In Regulating The Skeletal Response To Mechanical Loading, Julia P. Townsend, Russell P. Main

The Summer Undergraduate Research Fellowship (SURF) Symposium

Estrogen’s biological functions are mediated by estrogen binding to estrogen receptors (ER). Understanding what role both ERα and ERβ have in bone maintenance and formation can contribute to possible treatment of osteoporosis. This study examined osteocyte specific deletion of ERβ in mice. The cross of ERβ-floxed mice with DMP1-8kb-Cre mice provided both experimental knockout mice as well as littermate control mice. At 24 weeks of age the left tibiae of all mice were mechanically loaded five days per week for two weeks to induce bone formation. Analysis of cortical bone was conducted using microcomputed tomography (microCT) to measure load-induced ...

Effects Of Antiepileptic Medications On Bone Density In Individuals With Intellectual And Developmental Disabilities, Carly R. Gregory, Hannah L. Stedge, Robyn K. Brandenburg 2016 Cedarville University

Effects Of Antiepileptic Medications On Bone Density In Individuals With Intellectual And Developmental Disabilities, Carly R. Gregory, Hannah L. Stedge, Robyn K. Brandenburg

The Research and Scholarship Symposium

Individuals with intellectual and developmental disabilities (IDD) are commonly prescribed antiepileptic drugs (AEDs) to manage seizures, manage behavior, and stabilize mood. Though research has been done on the effects of antiepileptic medications in patients with epilepsy, little study has been done on the persons with intellectual and developmental disabilities population. After surveying IDD patients with a history and current use of AEDs on osteoprotective behaviors, we were unable to use SPSS due to incomplete surveys and low sample sizes. However, we were still able to analyze for common themes, and we found that the most prevalent use of AEDs was ...


Predictive Value Of The Functional Movement Screen As It Relates To Anterior Cruciate Ligament Injury, Daniel A. Herring, Kyle D. Cherry, Hannah L. Stedge 2016 Cedarville University

Predictive Value Of The Functional Movement Screen As It Relates To Anterior Cruciate Ligament Injury, Daniel A. Herring, Kyle D. Cherry, Hannah L. Stedge

The Research and Scholarship Symposium

Introduction: Anterior cruciate ligament injuries occur over 200,000 times annually in the United States alone (Brophy, et al. 2009). This injury strains the healthcare system and affects the players, teams, parents, and the organization they are a part of. There have been, however, clinically researched risk factors that predispose athletes to ACL injury (Gignac, et al. 2015; Laible, et al. 2014). As a result, there is a clinical need for an effective screening tool to identify those athletes at risk for ACL injury. The Functional Movement Screen has been shown to be an effective screening tool for detecting athletes ...

Intravascular Atp And The Regulation Of Blood Flow And Oxygen Delivery In Humans, Anne Crecelius, Brett Kirby, Frank Dinenno 2016 University of Dayton

Intravascular Atp And The Regulation Of Blood Flow And Oxygen Delivery In Humans, Anne Crecelius, Brett Kirby, Frank Dinenno

Anne R. Crecelius

Regulation of vascular tone is a complex response that integrates multiple signals which allow for blood flow and oxygen supply to appropriately match oxygen demand. Here, we discuss the potential role of intravascular ATP as a primary factor in these responses and propose that deficient ATP release may contribute to impairments in vascular control exhibited in aged and diseased populations.


Vascular Regulation Via Kir Channels And Na+ /K+-Atpase, Anne Crecelius, Frank Dinenno 2016 University of Dayton

Vascular Regulation Via Kir Channels And Na+ /K+-Atpase, Anne Crecelius, Frank Dinenno

Anne R. Crecelius

Despite the longstanding knowledge that blood flow increases in proportion to metabolic activity of skeletal muscle, the underlying mechanisms that govern this response have only recently been identified.1 Given the role of endothelial cells in mediating exercise hyperemia,2 interest has been focused on endothelium-derived vasodilation occurring via the synthesis of nitric oxide (NO) and vasodilating prostaglandins (PGs; i.e. prostacyclin) or endothelium- derived hyperpolarization. A number of studies performed in humans have established a minimal-to-modest role for NO and PGs during mild- and moderate- intensity exercise. In animal preparations, prevention of hyperpolarization attenuates contraction-induced hyperemia; however, performing similar ...


Kir Channel Activation Contributes To Onset And Steady-State Exercise Hyperemia In Humans, Anne Crecelius, Gary Luckasen, Dennis Larson, Frank Dinenno 2016 University of Dayton

Kir Channel Activation Contributes To Onset And Steady-State Exercise Hyperemia In Humans, Anne Crecelius, Gary Luckasen, Dennis Larson, Frank Dinenno

Anne R. Crecelius

We tested the hypothesis that activation of inwardly rectifying potassium (KIR) channels and Na+-K+-ATPase, two pathways that lead to hyperpolarization of vascular cells, contributes to both the onset and steady-state hyperemic response to exercise. We also determined whether after inhibiting these pathways nitric oxide (NO) and prostaglandins (PGs) are involved in the hyperemic response. Forearm blood flow (FBF; Doppler ultrasound) was determined during rhythmic handgrip exercise at 10% maximal voluntary contraction for 5 min in the following conditions: control [saline; trial 1 (T1)]; with combined inhibition of KIR channels and Na+-K+-ATPase alone [via barium chloride (BaCl2 ...


Hip Flexor Extensibility And Its Correlation To Hip Hyperextension And Lower Back Pain In Dancers, Tessa Richards 2016 University of Montana, Missoula

Hip Flexor Extensibility And Its Correlation To Hip Hyperextension And Lower Back Pain In Dancers, Tessa Richards

Undergraduate Theses and Professional Papers

In the world of ballet, flexibility and strength are the keys to success. A leg extended to extraordinary heights is equated with beauty and expertise, whereas a lower height is seen as lesser quality. Dancers are trained from their first ballet lesson to reach their toes to the utmost end of their range of motion, and push themselves beyond the regular restrictions of the human body. Despite the pressure put on dancers to be extremely flexible, tight hip flexor muscles (the rectus femoris and the iliopsoas group) are a common complaint, restricting hip hyperextension (called an arabesque). To compensate for ...

A secondary aim of this research was to determine whether quadriceps strength, voluntary activation, and/or corticomotor excitability assessed in patients prior to ACLr and/or at three months after surgery, is predictive of lower extremity postural control and/or self-reported ...


Displacement Across A Fracture Gap With Axial Loading Of Far Cortical Locking Constructs, Peter Wagner, Dennis Murphy, Kristen Billiar, Judith Siegel, John Wixted 2015 University of Massachusetts Memorial Medical Center

Displacement Across A Fracture Gap With Axial Loading Of Far Cortical Locking Constructs, Peter Wagner, Dennis Murphy, Kristen Billiar, Judith Siegel, John Wixted

Kristen L. Billiar

Purpose: Far cortical locking has been proposed for reducing stiffness and promoting greater dynamic stability in locked plating constructs. Prior studies have shown reduced stiffness with axial loading of these constructs, leading to a theoretical increase in inter-fragmentary motion and secondary bone healing. The purpose of this study was to examine strain across a fracture gap using far cortical locking constructs in a biomechanical model of distal femoral fractures.

Methods: Fourth generation sawbones were cut transversely along the distal diaphysis and plated with distal femoral buttress plates and cortical locking screws. Far cortical locking (FCL) specimens were predrilled in the ...
