International Journal of Exercise Science: Conference Proceedings

Persistent quadriceps dysfunction following anterior cruciate ligament reconstruction (ACLR) may lead to further pathological complication. Quadriceps weakness has been linked to corticospinal excitability. However, it remains unclear how this altered corticospinal excitability contributes to ACLR patients during knee strength tasks when compared to healthy controls. PURPOSE: The purpose of this study was to examine force reproduction strategies during isometric knee extension between ACLR patients and healthy controls. METHODS: Five ACLR (20.40±1.67yrs, 72.12±12.87kg, 171.07±7.40cm) participants and five matched healthy controls (21.00±1.73yrs, 65.77±13.61kg, 166.62±11.99cm) performed an isometric force reproduction task. They were instructed to maintain 10% of maximal voluntary isometric contraction (MVIC) …

Social Jetlag Inhibits Exercise-Induced Adaptations In The Heart And Alters Markers Of Mitochondrial Dynamics, Graham R. Mcginnis, Michael B. Dial, Elias M. Malek, Greco Neblina, Austin Cooper, Nikoleta Vasileva, Tanner Erwin

International Journal of Exercise Science: Conference Proceedings

Social jetlag (SJL), or the shifting of behavior and sleep times between weekdays and weekends, is a pervasive form of circadian rhythm disruption that affects nearly 70% of the population to some extent. The magnitude of SJL can be determined by the difference in the mid-sleep phase between weekends and weekdays. Higher levels of SJL have been associated with lower levels of cardiorespiratory fitness, and increased incidence of cardiometabolic disease, which may be due, in part, to mitochondrial dysfunction. However, no studies to date have evaluated the effects of long term SJL on cardiac mitochondrial dynamics. PURPOSE: To determine …

Effects Of Partial Hot Water Immersion On Postprandial Blood Glucose And Heart Rate Variability, Jeff Moore, Michael Buono

International Journal of Exercise Science: Conference Proceedings

The acute effects of heat therapy on glycemic markers oppose those of the chronic effects. While the postprandial glucose response is exaggerated during whole body heat exposure, chronic heat exposure lowers HbA1c. Additionally, the acute effects of heat therapy differ depending on the amount of body exposed to heat. Heating a single hand does not increase fasting glucose and lowers postprandial glucose. The opposing effects of partial and whole body heat exposure could be mediated in part from increased sympathetic nervous system (SNS) activity following heat stress. While heating the body increases muscular blood flow and glucose uptake, SNS activation …

Validation Of Vertical Force Measures During Hop Tasks Using Pressure Insoles, Andrew Cho, Erin Cagle, Sylwia Lipior, Susan Sigward

International Journal of Exercise Science: Conference Proceedings

Assessment of vertical ground reaction forces (vGRF) during jumping and landing tasks is commonly used as a tool to quantify limb loading following injury. While embedded force plates are the current gold standard, cost and poor ecological validity limit their feasibility for assessment of loading during sport agility tasks. Wearable pressure insoles can measure plantar pressure wirelessly and may provide an alternative for on-field assessments. Previous studies have assessed the validity of insoles with varying results. Few studies have considered tasks that require both vertical and horizontal forces similar to those required for agility tasks. This may have important implications …

The Lived Experience Of Second-Degree Nursing Students’ Anxiety Before And During Their Initial Clinical Rotation, Shelly Wheatley

Graduate Theses, Dissertations, and Capstones

Anxiety in nursing students can impact learning. Literature has shown that nursing students, especially those in second-degree nursing programs, report higher stress levels compared to other undergraduate students (Penprase & Koczara, 2009). Nursing clinicals can be jarring for students and present many stressors that can impeded learning and cause poor clinical performance. Much research has been done about traditional undergraduate students’ feelings of anxiety. There is a noted gap in research of second-degree, accelerated nursing students and their feelings about their initial clinical placement. Comparisons have often been made between traditional and nontraditional students, but the lived experiences of second-degree …

Endoscopic Retrograde Cholangiopancreatography-Related Early Perforations: A Study Of Effects Of Procedure Duration, Complexity, And Endoscopist Experience, Mark Aloysius, Hemant Goyal, Tejas Nikumbh, Niraj James Shah, Ghassan M Hammoud, Pritesh Mutha, Mairin Joseph-Talreja, Savio John, Ganesh Aswath, Vaibhav Wadhwa, Nirav Thosani

Faculty, Staff and Student Publications

BACKGROUND: Perforations (Perf) during endoscopic retrograde cholangiopancreatography (ERCP) are rare (< 1%) but potentially fatal events (up to 20% mortality). Given its rarity, most data is through case series studies from centers or analysis of large databases. Although a meta-analysis has shown fewer adverse events as a composite (bleeding, pancreatitis, Perf) during ERCP performed at high-volume centers, there is very little real-world data on endoscopist and center procedural volumes, ERCP duration and complexity on the occurrence of Perf.

AIM: To study the profile of Perf related to ERCP by center and endoscopist procedure volume, ERCP time, and complexity from a national endoscopic repository.

METHODS: Patients from clinical outcomes research initiative-national endoscopic database (2000-2012) who underwent ERCP were stratified based on the endoscopist and center volume (quartiles), and total procedure duration and complexity grade of the ERCP based on procedure details. The effects of these variables on the Perf that occurred were studied. Continuous variables were compared between Perf and no perforations (NoPerf) using the Mann-Whitney U test …

Differential Contribution Of Cardiac And Peripheral Blood Flow To Metaboreceptor-Mediated Pressor Responses In Autism Spectrum Disorder, Matthew Pizano Gomez, Gabriel B. Carlota, Stephanie S. Wang, Areum K. Jensen

International Journal of Exercise Science: Conference Proceedings

Young adults with Autism Spectrum Disorder (ASD) experience a higher prevalence of hypertension than the general population. Abnormal blood pressure (BP) response to acute exercise is seen in hypertension. BP response evoked during exercise is the outcome of a central interaction between neural inputs such as the exercise pressor reflex. However, it is unclear if this neurocardiovascular interaction is altered differently to regulate BP during exercise in ASD. PURPOSE: To determine whether contributions of cardiac and peripheral blood flow to metaboreceptor-mediated pressor responses are different during exercise in ASD. METHODS: 21 young adults with and without ASD completed the study. …

International Journal of Exercise Science: Conference Proceedings

Characterizing exercise gas exchange response dynamics reveals important information about physiological control processes and cardiopulmonary dysfunction. However, current methods for extracting exercise response dynamics typically use multiple step-wise transitions, limiting applicability of this technique. PURPOSE: We designed a new protocol (chirp waveform) to extract exercise gas exchange response dynamics in a single visit. We tested the hypothesis that gas exchange response dynamics extracted from chirp forcing would be similar to those extracted from step-wise transitions. METHODS: Thirty-one participants (14 young healthy, 7 older healthy, and 10 patients with chronic obstructive pulmonary disease) visited the laboratory on three occasions. …

Low Back Demand Of Equipment Carriage Tasks In Golf, Guanrong Cai, Jacob Cho, Yunsheng Zou, Jordan Cannon, George Salem

International Journal of Exercise Science: Conference Proceedings

Low back injury is a common concern in golfers and caddies. The literature often points to the biomechanics of the golf swing as the major contributing factor; however, golfers and caddies can regularly walk upward of 10,000 steps on uneven terrain while carrying equipment, which can contribute to the cumulative load on the low back. PURPOSE: To examine the low back biomechanical demands during golf equipment carriage and pick-up tasks. METHODS: Sixteen golfers (11M/5F, 27.4±3.5yrs) participated in 3D motion capture of a golf bag pick-up task and 3 walking tasks (1. unloaded walking [UW], 2. unilateral carrying on …

Examining Stroke Volume Changes During Exercise In Healthy Young Adults, Thomas Clark, Anthony Ciccone, Zane Evans, Keslee Stephenson, Chandler Rose, Carlos Goff, Shane Draper, Nicolas Clark

International Journal of Exercise Science: Conference Proceedings

Cardiac output is determined by the combination of heart rate and stroke volume. While heart rate is primarily influenced by cardiac autonomic input, stroke volume's behavior is more intricate due to the interplay between myocardial response to stretch (Frank-Starling law) and adrenergic changes in contractility. No consensus exist on its behavior during exercise despite extensive data. PURPOSE: The aim of this study was to assess how normalized stroke volume scores (SV) change in young, healthy adult males during a graded exercise test to exhaustion (GXT). METHODS: Participants (n=20; age=22.9±2.4; BMI=23.7±2.4) were instructed to abstain from engaging in vigorous …

Validation Of The Work Capacity Test For Wildland Firefighters, Cassandra Mcfarland, Zachary Hofheins, Janna Thompson, Lexi Sorensen, Andrew Creer, Shane Draper

International Journal of Exercise Science: Conference Proceedings

Much of the reported Wildland Firefighter (WLFF) data use prediction equations which tend to underestimate oxygen consumption (VO2) during load carriage. As a result, the reported metabolic and oxygen consumption data values may actually be higher creating a larger gap between the US Forest Service arduous pack test (APT) and true occupational demand. The reported data regarding the energy cost upon which the APT has been based (22.5 mL/kg/min of oxygen) has overwhelmingly been tested in current WLFF with few participants. However, no studies have recently examined the current energy expenditure of men and women who want to qualify to …
