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 …

A Comparison Of The Effects Of Moderate-Intensity Continuous Cycling And High-Intensity Interval Cycling On Postprandial Lipemia And Glycemia, Autumn Oliver, David J. Buckley, James R. Rowe Jr
International Journal of Exercise Science: Conference Proceedings
Both moderate-intensity continuous exercise (MICE) and high-intensity interval exercise (HIIE) has been reported to reduce the magnitude of postprandial lipemia and glycemia. It is unclear if performing MICE or HIIE of similar duration and work would have a comparable effect on postprandial lipemia or glycemia. PURPOSE: Examine the postprandial lipemic and glycemic response following the completion of high-intensity interval cycling (HIIC) and moderate-intensity continuous cycling (MICC) that is of equal duration and comparable work output. METHODS: Participants were mildly active males (n = 12; age = 21.9 ± 1.8 yrs; body mass = 90.1 ± 16.8 kg; BF% = …

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
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: …

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
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 …

International Journal of Exercise Science: Conference Proceedings
Mental toughness (MT) has been associated with competitive and non-competitive performance indicators in sport. On average, mentally tougher participants tend to be more successful. However, even in team-sport research, team MT is often disregarded over individual MT measurements. Results in team settings are trivial on whether team MT is related to athletic achievement/competitive performance. Volleyball is under-investigated in the applied MT literature. PURPOSE: To explore the relationship between team MT levels and competitive performance in volleyball. METHODS: Five national volleyball teams (i.e., Cuba, Mexico, Suriname, Dominican Republic, USA) were recruited during the XIV Men’s Pan American Cup ( …

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 …
