Health and Kinesiology Faculty Publications

Although theoretically sound, the accuracy and precision of 31P-magnetic resonance spectroscopy (31P-MRS) approaches to quantitatively estimate mitochondrial capacity are not well documented. Therefore, employing four differing models of respiratory control [linear, kinetic, and multipoint adenosine diphosphate (ADP) and phosphorylation potential], this study sought to determine the accuracy and precision of 31P-MRS assessments of peak mitochondrial adenosine-triphosphate (ATP) synthesis rate utilizing directly measured peak respiration (State 3) in permeabilized skeletal muscle fibers. In 23 subjects of different fitness levels, 31P-MRS during a 24-s maximal isometric knee extension and high-resolution respirometry in muscle fibers from the vastus lateralis was performed. Although significantly …

Effects Of A High-Intensity Interval Training Program Versus A Moderate-Intensity Continuous Training Program On Maximal Oxygen Uptake And Blood Pressure In Healthy Adults: Study Protocol For A Randomized Controlled Trial, Victor Hugo Arboleda Serna, Elkin Fernando Arango Vélez, Rubén Darío Gómez Arias, Yuri Feito

Faculty Articles

Background: Participation in aerobic exercise generates increased cardiorespiratory fitness, which results in a protective factor for cardiovascular disease and all-cause mortality. High-intensity interval training might cause higher increases in cardiorespiratory fitness in comparison with moderate-intensity continuous training; nevertheless, current evidence is not conclusive. To our knowledge, this is the first study to test the effect of high-intensity interval training with total load duration of 7.5 min per session. Methods: A randomized controlled trial will be performed on two groups of healthy, sedentary male volunteers (n = 44). The study protocol will include 24 exercise sessions, three times a week, including …

Mitochondrial Function In Heart Failure: The Impact Of Ischemic And Non-Ischemic Etiology, Song-Young Park, Joel D. Trinity, J. R. Gifford, Nikolaos A. Diakos, Lauren Mccreath, Stavros Drakos, Russell S. Richardson

Health and Kinesiology Faculty Publications

Background

Although cardiac mitochondrial dysfunction is associated with heart failure (HF), this is a complex syndrome with two predominant etiologies, ischemic HF (iHF) and non-ischemic HF (niHF), and the exact impact of mitochondrial dysfunction in these two distinct forms of HF is unknown.

Methods and results

To determine the impact of HF etiology on mitochondrial function, respiration was measured in permeabilized cardiac muscle fibers from patients with iHF (n = 17), niHF (n = 18), and healthy donor hearts (HdH). Oxidative phosphorylation capacity (OXPHOS), assessed as state 3 respiration, fell progressively from HdH to niHF, to iHF (Complex I + …

Harness Suspension Stress Physiological And Safety Assessment, James Marc Beverly

Health, Exercise, and Sports Sciences ETDs

Background: No robust trials including imaging or biomarkers have been performed to evaluate the possible stress of hanging motionless in a harness (harness suspension stress -HSS). Untoward effects are from case reports and sparsely documented data, leaving the topic open to debate. No cause-effect relationship has been established, therefore providing no guide to diagnostic, prognostic, or therapeutic evaluation or treatment for possible detrimental effects of HSS. Expert opinion provides the majority of the literature concerning HSS. Many of the effects of HSS have been correlated to other syndromes or causes, but none have been excluded, and none have been established. …

Method: Forty-six internal medicine residents participated in this purposely designed computerized study. Every participant solved four case scenarios with one of two versions of a patient's picture for each scenario. In this study simulated patients’ pictures were used to play the role of poor and dirty patients in one condition and rich and clean in another condition. …

The Relevance Of Neuroscientific Research For Understanding Clinical Reasoning, Jerome. I. Rotgans, Naomi Low-Beer, Lucy Victoria Rosby

Health Professions Education

The current debate on clinical reasoning revolves primarily around Dual-Process Theory. This theory suggests that there are two distinctively separate cognitive systems underlying thinking and reasoning; commonly referred to as System 1 and System 2.1 System 1 is considered intuitive, fast and reliant on automatic activation of “illness scripts” stored in memory and leading to effortless pattern recognition. System 2 on the other hand is considered analytic, slow, deliberate, and systematic. The clinical reasoning literature is divided; one group of researchers defending System 1 reasoning as the hallmark of expert decision-making, whereas the other camp of researchers considers System 2 …

Experiential Learning, Spatial Visualization And Metacognition: An Exercise With The “Blank Page” Technique For Learning Anatomy, Helen L. Naug, Natalie J. Colson, Daniel Donner

Health Professions Education

Purpose: Undergraduate students in the allied health science disciplines are normally required to complete a human anatomy course in their first year. Such courses, while popular, present challenges in that the content requires students to engage different approaches to learning. Recent literature reflects an increased interest in active, experiential learning activities to improve the learning of anatomy and physiology, but activities that focus on the development of metacognitive skills and visual-spatial thinking have been lacking. To address these inadequacies we developed a plasticine modeling and drawing activity in a tutorial room devoid of resources and visual cues referred to as …

The Effects Of The Fifa 11+ Warm Up Program In Female Collegiate Soccer Athletes, Stacey O’Neill

Graduate Theses

As of 2010 there were over 265 million registered soccer athletes worldwide, and in particular, the number of women players were rapidly increasing (Soligard, et al., (2010). Consequently, playing soccer accounts for approximately one quarter of all injuries in sport, and due to its nature of jumping, pivoting and cross-cutting, the majority of these are non-contact, lower extremity injuries. Therefore, playing soccer entails a substantial amount of injury risk for its participants. The purpose of this study was to investigate the effects of the FIFA 11+ Warm Up Program in collegiate female soccer athletes.
