Exaggerated Pulsatility During Exercise Is Associated With Reduced Muscle Strength And Quality In Elderly Hypertensives, Stephen M. Fischer, Arun Maharaj, Arturo Figueroa Feb 2020

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 …

Reduced Muscle Sympathetic Nerve Activity Response To A Cold Pressor Test In Multiple Sclerosis, Claire E. Trotter, Mu Huang, David M. Keller, Scott L. Davis

International Journal of Exercise Science: Conference Proceedings

Multiple sclerosis (MS) is a neurodegenerative autoimmune disease characterized by demyelination in the central nervous system leading to potential impairments in the autonomic control of cardiovascular function. We have previously demonstrated individuals with MS exhibit a diminished ability to increase blood pressure in response to a hypotensive stimulus compared with healthy controls likely due to impaired sympathetic modulation of the vasculature. PURPOSE: The aim of the current investigation was to test the hypothesis that muscle sympathetic nerve activity (MSNA) responses to a cold pressor test (CPT) are reduced in individuals with MS compared to healthy controls. METHODS: Four …

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: …

Cutaneous And Muscle Reactive Hyperemia In Young Adults With Major Depressive Disorder, Sherri M. Pham, Rauchelle Richey, Salwa Shoaib, John D. Akins, Erika F.H. Saunders, R. Matthew Brothers, Jody L. Greaney

International Journal of Exercise Science: Conference Proceedings

The reactive hyperemic vasodilatory response to a brief period of tissue ischemia provides an index of microvascular function and is an independent predictor of cardiovascular morbidity and mortality. As such, reactive hyperemia is a non-invasive technique that is commonly utilized to provide an index of vascular health in various patient groups. Major depressive disorder (MDD), a non-traditional risk factor for cardiovascular disease (CVD), has been associated with blunted reactive hyperemia, though this is not a universal finding. Further, to date, the quantification of the reactive hyperemic response in adults with MDD has been limited to the forearm muscle, assessed as …

Heart Rate Variability Responses To Exercise In Mid-Spectrum Chronic Kidney Disease, Matthew Peterson, Jeffrey S. Forsse, Zacharias Papadakis, Peter Grandjean Feb 2020

Heart Rate Variability Responses To Exercise In Mid-Spectrum Chronic Kidney Disease, Matthew Peterson, Jeffrey S. Forsse, Zacharias Papadakis, Peter Grandjean

International Journal of Exercise Science: Conference Proceedings

Heart rate variability (HRV) is a measure of autonomic nervous system (ANS) activity, and decreased HRV is associated with many cardiovascular conditions. Chronic kidney disease (CKD) is characterized by a decrease in renal function and may be associated with ANS imbalances in the renal vasculature. Low HRV is associated with CKD incidence. Exercise is able to alter HRV by modulating the ANS. The effect of exercise on HRV in mid-spectrum CKD patients remains understudied. PURPOSE: To determine the effect of steady-state exercise (SSE) and high-intensity interval exercise (HIIE) on post-exercise HRV in patients with stage 3 or 4 CKD. …

Attempting To Acutely Manipulate Ground Contact Time Imbalances Impairs Running Economy, Broderick L. Dickerson, Eric J. Jones, Dani D. Willis, Dustin P. Joubert

International Journal of Exercise Science: Conference Proceedings

Running economy (RE) is a key performance determinant. Biomechanical markers have been linked to RE, including ground contact time (GCT), cadence, and vertical oscillation (VO). Recently, we showed a strong relationship between GCT imbalances and RE. Because these markers can be tracked real-time with consumer-wearable devices, runners now have access to instant feedback concerning their mechanics. PURPOSE: Determine if attempting to correct GCT imbalances real-time alters mechanics and RE. METHODS: 7 recreational runners (38 ± 15 years, 24.7 ± 2.8 kg/m2, 5 male) completed 2, 10-minute running trials (9.65 km/hr) on separate days. For both trials, subjects ran …

Sex Specific Responses To Perceptually Regulated Work-To-Rest Ratios During Resistance Training, Aaron Rinehart, Andrew Wolfe, Matt Laurent Feb 2020

Sex Specific Responses To Perceptually Regulated Work-To-Rest Ratios During Resistance Training, Aaron Rinehart, Andrew Wolfe, Matt Laurent

International Journal of Exercise Science: Conference Proceedings

Recovery has long been an important training variable, receiving increased attention within the scientific literature. While there has been considerable attention to intersession recovery, less is known about optimizing intrasession recovery. Additionally, growing evidence suggest women may experience relatively less fatigue with greater acute recovery as opposed to men when exercising at similar intensities. However, relatively little is known regarding the impact of self-regulated within session recovery between men and women during resistance training. PURPOSE: Therefore, the purpose of the research is to examine the sex specific responses to perceptually regulated work-to-rest ratios during strength training. METHODS: Participants (n …

Body Fat Gain Automatically Increases Lean Mass By Changing The Fat-Free Component Of Adipose Tissue, Matthew T. Stratton, Patrick S. Harty, Robert W. Smith, Jacob Dellinger, Baylor A. Johnson, Marqui Benavides, Abegale D. Williams, Sarah White, Christian Rodriguez, Grant M. Tinsley

International Journal of Exercise Science: Conference Proceedings

Estimating alterations in lean mass in response to various training interventions is a primary concern for many investigations. However, previous reports have suggested that lean mass estimates from weight loss interventions may be significantly altered by attempting to correct for changes in the fat-free component of adipose tissue (FFAT). This component, consisting primarily of water and protein, has been estimated as ~15% of adipose tissue (AT) mass. While a preliminary examination of this correction method has been conducted in the instance of weight loss, it has yet to be investigated after a period of purposeful weight gain and resistance training. …

No Changes In Appetite Stimulating Hormones Following Swimming And Cycling Exercise Interventions, Brandon G. Fico, Mohammed Alkatan, Yuzi Zhang, Hirofumi Tanaka Feb 2020

No Changes In Appetite Stimulating Hormones Following Swimming And Cycling Exercise Interventions, Brandon G. Fico, Mohammed Alkatan, Yuzi Zhang, Hirofumi Tanaka

International Journal of Exercise Science: Conference Proceedings

Swimming is a favorable and ideal modality of exercise for individuals with obesity and arthritis as it encompasses a minimal weight-bearing stress and a reduced heat load. However, the available evidence indicates that regular swimming may not be effective in reducing body weight and body fatness. A current hypothesis is that exercise in cold water somehow stimulates appetite. PURPOSE: We determined the effect of swimming exercise training on fasting concentrations of ghrelin, insulin, leptin, and peptide YY in obese individuals with osteoarthritis. Cycling training was included as a non-weight bearing land-based comparison group. METHODS: Thirty-nine obese participants with …
