Cardiovascular And Autonomic Nervous System Function: Impact Of Glucose Ingestion, Hydration Status And Exercise In Heated Environments, Kate Suzanne Early
Cardiovascular And Autonomic Nervous System Function: Impact Of Glucose Ingestion, Hydration Status And Exercise In Heated Environments, Kate Suzanne Early
LSU Doctoral Dissertations
Cardiovascular function is under the influence of autonomic nervous system, both of which can be assessed non-invasively. The purpose of this dissertation was to examine these non-invasive markers of cardiovascular and autonomic function and their relationships with exercise training, glucose ingestion and hydration status. A series of three studies were conducted to gain insight to various influences on cardiovascular and autonomic function. The first study examined the influence of exercise training of brachial artery flow-mediated dilation (BAFMD) using meta-analytic techniques. Sixty-six studies included in the analysis demonstrated exercise training improves BAFMD compared to controls. Results indicated exercise training significantly alters …

Vascular Function, Physical Performance And Aging, Devon Dobrosielski
LSU Doctoral Dissertations
This is a series of three experiments with brachial artery flow-mediated dilation (BAFMD) as the major outcome variable. The first study examined the temporal response of the brachial artery diameter following forearm occlusion in sixteen young (28±8 years) and fifteen older (85±8 years) men. Following release of the pressure cuff there is a significant reduction in brachial diameter compared to baseline, followed by a rapid increase to a PEAK. When comparing the magnitude of the decrease in diameter and the BAFMD between Young and Old, older subjects demonstrated a blunted response. A significant relation was noted between the magnitude of …
Arterial And Venous Adaptations To Short-Term Handgrip Exercise Training, Mahmoud Awad Alomari
Arterial And Venous Adaptations To Short-Term Handgrip Exercise Training, Mahmoud Awad Alomari
LSU Doctoral Dissertations
Four studies on vascular and exercise physiology are presented in this document. The 1st study examined the relationships between measures of fitness and FVF in 55 young [22.6 ± 3.5 years] adults. Estimated VO2peak correlated with arterial inflow (Ainf) [r=0.54; p=0.012] and resting venous outflow (Vout) [r=0.56; p=0.016]. Lastly, HG strength was associated with Vcap [r=0.57; p=0.007] and Vout [r=0.67; p=0.001]. The 2nd study examined the relationship between FVF and exercise tolerance (ExT) in 20 patients with HF [age: 59 ± 13 years] and 10 age-matched controls [age: 51 ± 16 years. The ExT was measured as the maximum …
Influence Of Short-Term Endurance Exercise Training On Heart Rate Variability, Clarence Matthew Lee
Influence Of Short-Term Endurance Exercise Training On Heart Rate Variability, Clarence Matthew Lee
LSU Doctoral Dissertations
The purpose of this investigation was to determine if 8 exercise endurance training (ET) sessions over 2 weeks significantly alters cardiac autonomic modulation, as measured by heart rate variability (HRV). Twenty-four college-aged males were recruited for this study and were randomized into either an exercise group (EX; n=12) or a control group (CT; n=12). EX underwent 2 weeks of ET on a cycle-ergometer (frequency: four times/week; duration: 40 minutes; intensity 80-85% HRreserve), whereas CT was instructed not to alter their previous level of physical activity. Five-minute ECG tracings were collected for HRV under the following conditions: 5 minutes of paced …
