The Ventilatory Response To Modified Rebreathing Is Unchanged By Hyperoxic Severity: Implications For The Hyperoxic Hyperventilation Paradox, Joshua D. Huggard
The Ventilatory Response To Modified Rebreathing Is Unchanged By Hyperoxic Severity: Implications For The Hyperoxic Hyperventilation Paradox, Joshua D. Huggard
Electronic Thesis and Dissertation Repository
We measured the ventilatory response to hyperoxic CO2 rebreathing with O2 tension clamped at increasingly higher pressures. We hypothesized that the V̇E versus PCO2 relationship is fixed and independent of PO2. Twenty participants (10 females; mean± SD age: 24±4 years) performed three repetitions of modified rebreathing in 4, randomized, isoxic-hyperoxic conditions: mild: PO2=150 mmHg; moderate: PO2=200 mmHg; high: PO2=300 mmHg; and extreme: PO2≈700 mmHg. For each rebreathing trial, the PETCO2 at which V̇E rose was identified as the ventilatory recruitment threshold (VRT, …

Theses and Dissertations
This paper supports the MFA dance thesis film BodyVerse. Exploring the intertwining relationship of body systems with the natural world, it brings somatic principles such as Body Mind Centering and dance improvisation together with film legacies and digital platforms.
Effects Of A Postural Restoration Focused Intervention On Muscle Activation During Deadlifts, Caleb Richardson
Effects Of A Postural Restoration Focused Intervention On Muscle Activation During Deadlifts, Caleb Richardson
Human Movement Sciences & Special Education Theses & Dissertations
The purpose of this study was to determine the efficacy of implementing two Postural Restoration exercises and relating principles on deadlifts using a hexagonal barbell. Specifically, we aimed to examine the effects of the intervention on muscle activation and the location of the ground reaction force (GRF) center of pressure. Sixteen subjects (age 18-35 yrs.; male (n=14); female (n=2)), with at least 1 year of deadlifting experience, were randomly assigned into a control and intervention group (both n=8). Both groups performed two sets of three repetitions of deadlifts at 50% and at 80% of their estimated one repetition maximum (1-RM). …
Heart Rate Recovery And Blood Pressure Recovery Influenced By A Slow-Breathing Protocol After Exercise In Moderately Trained Females, Emily Layne Zumbro
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
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
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 …
