Changes in Vascular and Hemodynamic Parameters Following Acute Exercise and Antioxidant Supplementation 2010 1560 Objective: The objective of this study was to investigate the potential additive effects of the multi-flavonoid plus fish oil combination and aerobic exercise on post exercise hypotension (PEH). We hypothesize that the use of a multi-flavonoid plus...
The effects of aerobic exercise timing on sleep architecture 2011 8140 It is well known that the quality of sleep has direct effects on the manifestations of disease. Further, exercise has been shown to enhance the quality of sleep, yet little is known regarding how exercise effects sleep stages. Our laboratory has s...
The Effects of Four Weeks of Aerobic Training on Arterial Stiffness and the Renin-Angiotensin & Aldosterone System on Stage One Hypertensive Obese Individuals 2011 2590 Increases in blood pressure (BP) are directly related to increases in body mass and obesity related hypertension is associated with pronounced activity of the renin-angiotensin-aldosterone system (RAAS) and increased pulse wave velocity (PWV). The p...
Sex Differences in Cardiac Autonomic Modulation and Baroreflex Sensitivity Following Differential Exercise Training 2011 1425 Maintained balance between sympathetic and parasympathetic tone within the cardiac autonomic systems is a vital component of cardiovascular regulation. The alteration of baroreflex function can contribute to chronic parasympathetic withdrawal and sub...
Effects of Aerobic Exercise on Nocturnal Blood Pressure Dipping in Prehypertensive Individuals 2011 3341 Fifteen prehypertensive individuals completed a 30 minute timed bout of moderate intensity aerobic exercise at 7 AM, 1 PM, and 7 PM. Following each exercise bout, the subject’s were outfitted with an ambulatory blood pressure cuff and their blood pre...
Changes in Cardiac Autonomic Modulation in Children Following 4 and 8 Weeks of Supervised Summer Activity 2011 1389 Background: Pediatric obesity is associated with lower physical activity levels and a decrease in cardiac autonomic modulation. Physical activity contributes cardiovascular improvements via increases in heart rate variability. However involvement in ...
The Effects of a Multi-Flavonoid Supplement on Vascular and Hemodynamic Parameters in Older Pre-Hypertensives 2012 1174 Antioxidants have been shown to increase vasodilation, increasing vascular distensibility and decreasing blood pressure (BP) in individuals with elevated BP; therefore an additive effect would be expected when combined with exercise. The purpose of t...
The Effects of a Multi-Flavonoid Supplement on Cardiac Autonomic Regulation 2012 1610 Antioxidant supplementation has been shown to stimulate positive effects on cardiovascular health including a reduction in blood pressure by alleviating arterial stiffness, but little is known of the benefits of antioxidants on the autonomic nervous ...
Hemodynamics and Sleep Architecture Following Acute Alcohol Ingestion in College Age Males 2013 1469 Hypertension is a progressive disease characterized by elevated blood pressures which can cause damage to arteries and increases afterload leading to myocardial remodeling and a progressively worsening cardiovascular function. This increase in afterl...
Effects of Resistance Exercise Timing on Sleep Architecture 2014 2696 Short sleep duration and poor sleep quality have been associated with numerous health risks. Prior research has suggested that regular aerobic exercise improves sleep quality; however, less is known regarding how resistance exercise (RE) may affect ...
Resistance Exercise Timing Effects on Blood Pressure 2014 2377 Research shows that resistance exercise can lower blood pressure, yet little is known regarding the best time for resistance exercise for the greatest blood pressure benefit; therefore, the purpose of this study is to evaluate the effects of resistan...
Effects of a History of Concussions on Cognitive Function in Collegiate Wrestlers 2015 1727 A history of concussions has shown to affect neurocognitive degeneration, but it has not been investigated whether or not these aspects affect baseline cognitive scores. The purpose of this study was to investigate the effects a history of concussion...
Comparing Water Immersion Skin Wrinkling and Tilt Table Testing in a Young Healthy Population 2015 597 Tilt table testing (TTT) is the golden standard in evaluating vasovagal syncope, an autonomic function. Water immersion skin wrinkling (WISW) has recently been linked to autonomic function. The purpose of this study is to compare WISW and TTT in a yo...
Autonomic Function Responses Comparing Cold Pressor and Tilt Table Testing in a Healthy, Normotensive Population 2015 823 The autonomic nervous system regulates unconscious body functions, such as blood pressure, heart rate, respiration, and thermoregulation. Testing for autonomic dysfunction can be dangerous or costly, though it is crucial for individual wellbeing and...
Autonomic Function in Indoor Versus Mountain Bike Riding 2015 516 Road cycling and cross country mountain biking are common cycling disciplines. Cross country biking creates an adrenaline rush, which causes sympathetic nervous system, stimulation which can increase heart rate. Sympathetic and parasympathetic nerv...
Initial Validation Of Withings Pulse Wave Velocity And Body Composition Scale 2017 1438 Mobile devices, wearable technology, smartphone apps, and home fitness tracking have become popular to monitor personal health. While cardiovascular diseases are the leading cause of mortality, these devices have become a part of people’s lives as th...
Cardiovascular And Autonomic Responses To Resistance Training In Individuals With Down Syndrome 2018 205 Down syndrome (DS), also referred to as Trisomy 21, is a genetic disorder caused by a partial or full extra copy of the chromosome 21. Studies show that physical activity levels in individuals with DS are much lower than individuals without DS. Indiv...
Comparison Of Withings Bodycardio To Gold Standard Measurements Of Pulse-Wave Velocity And Body Compositon 2018 70 General Wellness Products (GWP) are widely used by consumers, human physiology scientists, and healthcare practitioners. However, current research on GWP accuracy is limited and often reports large inaccuracies. Purpose: The purpose of this study was...
Investigation Of Sex Differences Between Withings Body Cardio And SphygmoCor Applanation Technology 2019 84 Pulse wave velocity (PWV) is a widely utilized measure of cardiovascular health as a reflection of arterial stiffness. There is an emerging technology revolution to assess health with mobile monitors. The Nokia Health platform includes the Body Cardi...
Validity Of Withings Pulse Wave Velocity Scale Versus Gold Standard Applanation Tonometry And Body Composition Analysis In A Young Healthy Population 2019 90 Cardiovascular disease currently is the leading cause of death nationwide. Pulse Wave Velocity (PWV) is now considered a gold standard for measuring arterial health. Deleterious changes in arterial distensibility are risk factors for cardiovascular d...
