Establishing A Normative Respiratory Baseline For Diaphragmatic Breathing In The Geriatric Population, Madison M. Jensen, Connor J. Wright, Ty K. Hacking, James D. Mead, Ulrike Mitchell, Lauren Adams

Library/Life Sciences Undergraduate Poster Competition 2024

Respiratory function can be assessed through lung volume measurements such as tidal volume and vital capacity. It can also be assessed by measuring diaphragm mobility and thickness. The diaphragm is a muscle that contributes up to 75% of normal lung ventilation. It averages 1-2 cm of excursion during quiet breathing; this increases significantly to about 7-11 cm during forced breathing. Aging has influences on respiratory function. Diaphragmatic muscle strength decreases, and lung function, capacity, and compliance also decline. There is a steadily growing elderly population in the US and globally. Due to an aging population and the significance respiratory function …


Effects Of A Demand-Valve Scuba Regulator On Cardiorespiratory Response During Submaximal Exercise Under Normobaric Conditions: A Preliminary Investigation, Christopher R. Kovacs Ph.D., Camille Dhom B.S. Feb 2022

Effects Of A Demand-Valve Scuba Regulator On Cardiorespiratory Response During Submaximal Exercise Under Normobaric Conditions: A Preliminary Investigation, Christopher R. Kovacs Ph.D., Camille Dhom B.S.

International Journal of Aquatic Research and Education

SCUBA diving fatalities are often related to cardiac events triggered by stress linked to equipment. The purpose of this investigation was to examine the effects of a SCUBA regulator on cardiorespiratory exercise at a submaximal workload. Ten participants (mean = 21.5 yrs; s.d. = 1.16) completed two submaximal exercise tests at 1 ATA; one while breathing normally and a second while breathing directly from a demand valve SCUBA regulator. Total time to test completion (TOT), heart rate (HR), blood pressure (BP), rating of perceived exertion (RPE), and arterial oxygen levels were all assessed. No significant differences between conditions were found …


Heart Rate Recovery And Blood Pressure Recovery Influenced By A Slow-Breathing Protocol After Exercise In Moderately Trained Females, Emily Layne Zumbro Jan 2017

Heart Rate Recovery And Blood Pressure Recovery Influenced By A Slow-Breathing Protocol After Exercise In Moderately Trained Females, Emily Layne Zumbro

Electronic Theses and Dissertations

Heart rate (HR) and blood pressure (BP) increases in order to meet metabolic demands as a result of exercise primarily through way of the sympathetic nervous system (SNS) and parasympathetic nervous system (PNS). This study aimed to build on previous research in finding the best method to rapidly decrease HR and BP after exercise during the recovery period. PURPOSE: The purpose of this study was to determine the effectiveness of a breathing technique on HRR and BPR within a healthy female population during an exercise recovery period compared to active recovery and upright passive recovery. METHODS: Nine moderately trained female …


Effects Of Breathing Cool Air During Cycling Exercise In The Heat, Christian B. Ridings Aug 2014

Effects Of Breathing Cool Air During Cycling Exercise In The Heat, Christian B. Ridings

Graduate Theses and Dissertations

INTRODUCTION: The purpose of this study was to establish the ability of the Core Cooler device to prevent rises in physiological heat strain of trained male cyclists during cycling exercise in the heat. METHODS: 15 healthy male cyclists cycled at 50-70% VO2max for 75 minutes in a heat chamber of 31°C & 55% RH while breathing through the Core Cooler device under three different conditions: 1:4 ratio without ice termed control (CN), 1:4 ratio with ice termed low intermittent (LI), and at 1:1 ratio with ice termed high intermittent (HI). Data collected every 15 minutes assessing intestinal temperature (TGI), heart …


The Effect Of Wearing Mouthguards On Vo2, Ventilation, And Perceived Exertion At Two Different Exercise Intensities, Jeffrey Scott Hurst Mar 2004

The Effect Of Wearing Mouthguards On Vo2, Ventilation, And Perceived Exertion At Two Different Exercise Intensities, Jeffrey Scott Hurst

Theses and Dissertations

Objective: To assess the effects of wearing a protective mouthguard during exercise on ventilation and oxygen consumption.
Design and Setting: All participants performed a graded maximal exercise test on a cycle ergometer to determine peak oxygen consumption (VO2peak). Each participant also performed 6 submaximal exercise tests while wearing one of two facemasks (nasal or non-nasal breathing) and one of three mouthguard conditions (no mouthguard, boil and bite, custom-fit). Steady-state VO2, rate of perceived exertion (RPE), and other ventilatory values were measured at 60% and 80% of VO2max during each submaximal exercise test. All 6 submaximal exercise tests were completed within …
