Vascular Deficits In Native American Women With Metabolic Syndrome During Dynamic Exercise, Jerene Yazzie, Giselle Quiver, Abraham Gomez, Sydnee Yazzie, Ariel Gomez, Klaudia Szych, Matthew A. Barlow Phd
International Journal of Exercise Science: Conference Proceedings
Native Americans of the Southwest are predisposed to vascular diseases due to health disparate lifestyles influenced by diet, lack of exercise and decreased access to health care. These factors together may be responsible for the co-morbidities developed with Diabetes and Metabolic Syndrome (MetSyn) which are indicators of early onset cardiovascular disease. In a previous study, we evaluated Native Americans (NA) diagnosed with MetSyn or Type II Diabetes and compared the sedentary control NA and Caucasians (CA) during vascular measurements of FMD. We found that NA Control and MetSyn groups exhibited a decrease in vascular function during rate to peak and …

International Journal of Exercise Science: Conference Proceedings
Exaggerated cardiovascular (CV) responses to exercise can lead to adverse CV events. Previous studies have reported that P2X3 receptors, found on the peripheral endings of afferents, contribute to an exaggerated exercise pressor reflex in individuals with CV-related diseases. One way to investigate the role played by these receptors in CV pathophysiology is through immunoblotting. The Jess (Protein Simple) provides an automated option for the protein separation and immunoblotting of the traditional Western Blot and allows for total protein staining, an improvement over the use of loading controls to normalize for sample loading variability. PURPOSE: The purpose of this study …

Oxygen uptake measurements enable performance professionals, clinicians, and scientists to quantify energy expenditure and aerobic work capacity for various purposes. Devices that accurately detect the composition of expired gases and changes in oxygen uptake, open new possibilities in research methodology and accessibility. PURPOSE: The purpose of this study was to compare the O2 uptake measurements of the VO2 Master Pro (VM) to the Cosmed K5 (K5) during walking, jogging, and running in field and lab conditions. METHODS: Twelve proficient runners, with a current 10k pace < 5:19 min/km, performed 3 matched intervals at 3 different speeds (4.82, 8.05, 11.27 kph) on a treadmill and on an outdoor track while expired gasses were measured. Each interval was 10 minutes and data from minutes 6-9 were averaged for comparisons. An airflow test was performed on both devices by forcing air through the devices using a 3 L syringe timed to a metronome at 15, 25, and 35 strokes/min. RESULTS: During walking intervals, the VM did not report data for the majority …

International Journal of Exercise Science: Conference Proceedings
Cardiovascular disease has become the leading public health concern facing our nation. The American Heart Association estimates someone dies every 38 seconds from heart disease. Individuals who experience a severe cardiac incident are often required to undergo rehabilitation as part of their treatment program to improve overall cardiac function. Cardiac rehabilitation provides patients with guided, prescribed exercise programs that encourage the development of healthful behaviors to improve quality of life. Stress has been highly implicated as a contributing factor of cardiovascular disease. Chronic stress causes cardiovascular reactivity, elevations in stress-related hormones and depressed immune function increasing risk of additional cardiac …
Metabolic Costs Of Stair-Stepping Methods, Chelsea Banawis, Edward Merritt
Metabolic Costs Of Stair-Stepping Methods, Chelsea Banawis, Edward Merritt
International Journal of Exercise Science: Conference Proceedings
Walking up stairs is physically demanding, causing high levels of perceived exertion and increased oxygen consumption compared to level walking. While stair-climbing exercise can be used to improve one’s cardiorespiratory fitness, individuals often choose the elevator for convenience and to minimize perceived exertion. Determining if a single step or double step method of stair-climbing requires different levels of oxygen consumption, and thereby exertion, could provide useful information potentially encouraging people to use the stairs. PURPOSE: This study was performed to determine whether stair-climbing using the single step method or double step method on a staircase creates greater oxygen consumption. The …
An Assessment Of The Potential For Standardizing Various Measures Of Arterial Stiffness, Taha A. Alhalimi, Jisok Lim, Hirofumi Tanaka
An Assessment Of The Potential For Standardizing Various Measures Of Arterial Stiffness, Taha A. Alhalimi, Jisok Lim, Hirofumi Tanaka
International Journal of Exercise Science: Conference Proceedings
Arterial stiffness is an independent risk factor for cardiovascular disease. Different measures of arterial stiffness have been used to assess the impacts of exercise training interventions. One of the primary problems faced by investigators conducting systematic reviews and meta-analyses is the lack of standardized methodology to evaluate and compare efficacies of the existing and newly conducted exercise interventions on arterial stiffness. The reference standard measure of arterial stiffness is pulse wave velocity (PWV) while other commonly-used methodologies are ultrasound-derived arterial compliance and distensibility. PURPOSE: To describe standardized equations to convert common ultrasound-based measures of arterial stiffness (arterial compliance, distensibility, ß-stiffness …

International Journal of Exercise Science: Conference Proceedings
Young, otherwise healthy Non-Hispanic Black individuals have been shown to exhibit blunted vascular responsiveness compared to their Non-Hispanic White counterparts, which may be a potential mechanism leading to higher cardiovascular disease risk in this group. Racial differences in vascular function have largely been assessed using flow-mediated dilation (FMD). However, more recent studies have proposed the use of rhythmic handgrip (HG) as an alternative measure of vascular function. PURPOSE: To compare whether rhythmic HG exercise could be an alternative technique to FMD in assessing differences in vascular function between black and white individuals. METHODS: Brachial artery vasodilation was assessed in …

Exploring The Potential Role Of Family History Of Hypertension On Racial Differences In Sympathetic Vascular Transduction, Jane N. Cloud, Ben E. Young, Jody L. Greaney, Paul J. Fadel
International Journal of Exercise Science: Conference Proceedings
The prevalence of hypertension in Non-Hispanic Black (BL) men surpasses all other racial groups. Our laboratory has previously demonstrated exaggerated vasoconstrictor and blood pressure (BP) responses to spontaneous bursts of muscle sympathetic nerve activity (MSNA; sympathetic vascular transduction) in young, healthy BL men compared to their Non-Hispanic White (WH) counterparts. Because a family history of hypertension (FHH) further compounds cardiovascular risk, we wanted to begin to explore the potential impact of a positive (+) FHH on sympathetic vascular transduction. Whether a +FHH influences sympathetic vascular transduction in WH and/or BL men remains unknown. PURPOSE: To begin to explore if +FHH …

Acute Effect Of Hyperglycemia On The Mechanoreflex And Metaboreflex, Yu Huo, Ann-Katrin Grotle, Michelle L. Harrison, Audrey J. Stone
International Journal of Exercise Science: Conference Proceedings
Recent studies in both humans and rodents have shown that the mechanoreflex and metaboreflex are exaggerated in type 2 diabetes mellitus (T2DM). Hyperglycemia is a main characteristic of T2DM and is known to cause damage to both cardiovascular and nervous system structures. However, the acute effect of the presence of hyperglycemia on the mechanoreflex and metaboreflex are not known. PURPOSE: To determine the acute effect of hyperglycemia on the mechanoreflex and metaboreflex. METHODS: Experiments were conducted after an overnight fast in unanesthetized, decerebrated healthy male and female Sprague-Dawley rats. The mechanoreflex was evoked by stretching the Achilles tendon …

International Journal of Exercise Science: Conference Proceedings
Irritable Bowel Syndrome (IBS) is a functional disorder linked to disruptions in autonomic nervous system regulation, which could impair vascular homeostasis. Studies have shown that slow, deep breathing reduces muscle sympathetic nerve activity and arterial stiffness; however, its effects on autonomic regulation in adults with IBS have not been previously investigated. Moreover, the effects of breathing on microvascular endothelium function are unknown. PURPOSE: To investigate the effects of slow, deep breathing on measures of autonomic function and microvascular endothelial function in adults with IBS. METHODS: Adults (ages 18-65 years) with a formal diagnosis of IBS were enrolled and …

A Practical And Easier Measure Of Endothelial Function Applicable To The Routine Clinical Setting?, Melanie Heath, Drew Gourley, Morteza Naghavi, Stanley Kleis, Hirofumi Tanaka
International Journal of Exercise Science: Conference Proceedings
The VENDYS-II is an alternative, fully automated and noninvasive methodology to evaluate endothelial function using temperature change on finger as a surrogate measure of the magnitude of vascular reactivity index (VRI). Due to the simplicity, it could provide a more feasible technique to assess vascular endothelial function in the clinical setting and possibly for home-based measurements similar to blood pressure. A most recent modification to the technique includes the application of cuff occlusion at the base of a finger instead of the upper or lower arm. Purpose: To assess the validity of the VENDYS-II device compared with the standard …
Exaggerated Pulsatility During Exercise Is Associated With Reduced Muscle Strength And Quality In Elderly Hypertensives, Stephen M. Fischer, Arun Maharaj, Arturo Figueroa
Exaggerated Pulsatility During Exercise Is Associated With Reduced Muscle Strength And Quality In Elderly Hypertensives, Stephen M. Fischer, Arun Maharaj, Arturo Figueroa
International Journal of Exercise Science: Conference Proceedings
It is well-established that hypertensive individuals have an exaggerated systolic blood pressure in response to exercise. Leg muscle weakness is related to greater left ventricular (LV) mass in hypertensive individuals via exaggerated increases in blood pressure during aerobic exercise. Pulse pressure (PP) is an indicator of LV pulsatile hemodynamic load. Increased PP is associated with LV hypertrophy and dysfunction in older adults. PURPOSE: To determine differences in PP responses to resistance exercise in normotensive versus hypertensive older adults and the influence of lean mass and strength on these responses. METHODS: Nine normotensive (NTN) and 11 hypertensive (HTN) older adults (NTN …

Cerebrovascular Dysfunction Is Related To Depressive Symptom Severity In Young Adults, Rauchelle E. Richey, John Akins, Jeremiah C. Campbell, Erika F.H. Saunders, R Matthew Brothers, Jody L. Greaney
International Journal of Exercise Science: Conference Proceedings
Cerebral vasodilatory responsiveness is blunted in older adults (~70 yrs) with depressive disorders and is thought to contribute to the link between depressive symptomology and increased risk for neurocognitive (e.g., dementia) and cerebral vascular (e.g., stroke) diseases. In young adults with major depressive disorder (MDD), peripheral vascular endothelial dysfunction is present and graded in relation to the severity of depressive symptoms; however, to date, limited investigations have examined cerebral vasodilatory function in young otherwise healthy adults with MDD. PURPOSE: We tested the hypothesis that cerebral vasodilatory responsiveness to a hypercapnic stimulus would be blunted in young otherwise healthy adults …
The Relation Between Cognitive Function And Cerebral Vasodilatory Reactivity In Young Adults With Major Depressive Disorder, Salwa Shoaib, Rauchelle E. Richey, Sherri M. Pham, John D. Akins, Dahlia Mukherjee, Erika F.H. Saunders, R Matthew Brothers, Jody L. Greaney
The Relation Between Cognitive Function And Cerebral Vasodilatory Reactivity In Young Adults With Major Depressive Disorder, Salwa Shoaib, Rauchelle E. Richey, Sherri M. Pham, John D. Akins, Dahlia Mukherjee, Erika F.H. Saunders, R Matthew Brothers, Jody L. Greaney
International Journal of Exercise Science: Conference Proceedings
Major depressive disorder (MDD) has been associated with an elevated risk of developing neurocognitive diseases (e.g., dementia). Although the precise neurobiological mechanisms remain incompletely understood, cerebrovascular dysfunction is thought to directly contribute, at least in part, to impairments in cognitive function. Cerebral vasodilatory reactivity to a hypercapnic stimulus is blunted in older adults with MDD compared to age-matched non-depressed adults. Further, impaired cerebral vasodilation has been linked to reduced cognitive activity in older adults with depression. However, to date, limited studies have examined the relation between cognitive function and cerebrovascular function in otherwise healthy young adults with MDD. PURPOSE: …
