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 …
Reliability Of Wavelet Analysis Of Heart Rate Variability During Rest And Exercise, Deborah Jean Stone
Reliability Of Wavelet Analysis Of Heart Rate Variability During Rest And Exercise, Deborah Jean Stone
LSU Master's Theses
The reliability of wavelet analysis (DWT), of heart rate variability during rest and exercise was examined for this study. All twenty-three participants visited the lab on two separate occasions no less than four weeks apart. All twenty-three participants were subjected to the spontaneous breathing (SB1), and HG60 exercise condition. Of those twenty-three participants, nine performed the HG20 exercise condition as well. It was found that during the SB1 condition, the R-R intervals were fairly reliable between days. However, the reliability of all the HRV parameters (SDNN, spectral components and wavelet components) were quite poor. Interestingly, however, during HG20, the reliability …
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 …
