Acute Renal Responses To Moderate-Intensity Aerobic Exercise With Non-Traditional Markers Of Renal Health And Function In Healthy Individuals: A Pilot Study, David J. Buckley, Ahmed Ismaeel, Kathleen Adair, Autumn Oliver, Evlampia Papoutsi, Kaitlyn Prezioso, Panagiotis Koutakis, Jeffrey Forsse
International Journal of Exercise Science: Conference Proceedings
Aerobic exercise elicits a multitude of physiological improvements in both healthy and diseased populations. However, acute changes in renal function with aerobic exercise remain difficult to quantify by traditional marker serum creatinine (sCr) to estimate glomerular filtration rate (eGFR). Recently, novel biomarkers cystatin C (CyC) and urine epidermal growth factor (uEGF) have been introduced as more reliable markers of renal health and function to be used in conjunction with sCr to assess changes in renal health and function in mid-spectrum CKD. Potentially, greater changes in novel markers of renal health and function similar to mid-spectrum CKD can be observed in …

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 …

Females Have An Increased Sensitivity To Thermal Stress During Matched Exercise Metabolic Heat Production, Lauren Schoech, Kyleigh Allie, Paolo Miguel Salvador, Mauricio Martinez, Eric Rivas
International Journal of Exercise Science: Conference Proceedings
Females report greater sensitivity in pain and cold exposures. PURPOSE: It is unclear how thermal sensitivity is affected when the change for internal temperature (ΔTin) and metabolic heat production (MHprod) are matched during exposure to hot conditions. This project tested the hypothesis that females have enhanced sensitivity to thermal stress during exercise hyperthermia when ΔTin and MHprod is matched. METHODS:Twenty-two healthy active (7 day activity: 8620±3008 steps/day; VO2max: 49±10 mL/kg/min) adults (11M/11F, 22.4±4.9y, 169±7.6cm, 68.3±13kg) exercised at similar MHprod (M: 7.1±1.5 W/kg, F: 6.9±1.4 W/kg; P=0.32) for 60 min (cycle ergometer) …

International Journal of Exercise Science: Conference Proceedings
Body composition is an integral component of physiology and pathology, as well as an indication of how the musculoskeletal system changes over time in response to training and/or nutritional modifications. Two common methods of estimating body composition include bioelectrical impedance analysis (BIA) and dual-energy X-ray absorptiometry (DXA). There is a debate regarding the agreement between these two methods, and it is thought that the population being tested may influence the similarity of estimates obtained by these technologies. Limited data comparing these two methodologies in athletic populations are available. PURPOSE: The purpose of this study was to take examine the agreement …

Global and regional deficits in cerebral blood flow are reported with concussions, a major public health concern, with approximately 3.8 million incidences occurring annually in the United States alone. Recent studies have identified an increased risk of musculoskeletal injuries in athletes upon return-to-play. Complexity index is a sensitive marker of postural control, with low complexity index indicating a poor physiological adaptation to stress. PURPOSE: Twofold; 1. Examine complexity index and dynamic cerebral autoregulation (dCA) at rest and during physical stress (rhythmic squatting) in collegiate athletes following a concussion in comparison to non-injured controls. 2. Examine the association between complexity …
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
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
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 …

Acute Vs. Chronic Citrulline Malate Supplementation On Muscle Fatigue, Alyssa N. Fick, Tyler M. Farney, Matthew S. Stone, Robert J. Kowalsky, Christopher M. Hearon
International Journal of Exercise Science: Conference Proceedings
Citrulline malate has been proposed to aid in reducing fatigue by increasing blood flow through promoting an increase in the nitric oxide synthase pathway along with the ability to remove ammonia and lactate accumulations. Results on the effectiveness of an acute supplementation are mixed, but it is proposed that regular consumption may help to attenuate the onset of fatigue during exercise. PURPOSE: To investigate the effects of acute and chronic citrulline malate supplementation on fatigue rate of the quadriceps. METHODS: Recreationally trained males (n=18, 24±5 yr, 83±14 kg, 174±6 cm) participated in seven testing sessions. The familiarization …

A Comparison Of An Aerobic Exercise Program And A Resistance Training Program On Cognitive Functioning In Healthy College Students, Samantha H. Gonzalez, Amber M. Shipherd, Tyler Farney
International Journal of Exercise Science: Conference Proceedings
Cognitive functioning declines begin occurring as early as 30 years of age. Research has found evidence that exercise influences cognitive functioning in elderly patients with Alzheimer's and dementia. However, while cognitive functioning has often been linked to academic achievement, there is a lack of research examining exercise and cognitive functioning in young and healthy populations. Furthermore, research has found both aerobic and resistance training can impact cognitive functioning, but there is a lack of literature comparing the impact of exercise mode on cognitive functioning. PURPOSE: To explore the differences between an aerobic and resistance training program on cognitive functioning …

Harty, Baylor A. Johnson, Jacob R. Dellinger, Marqui L. Benavides, Bradley Vincent, Abegale D. Williams, Sarah J. White, Grant M. Tinsley
International Journal of Exercise Science: Conference Proceedings
Two critical components of muscular performance are muscular strength (e.g., the maximal load that can be lifted for a given exercise) and muscular endurance (e.g., the maximal number of repetitions that can be performed at a given load). When seeking improvements in muscular performance, it is common to employ nutritional strategies that create an energy surplus and a resultant gain in body mass. Varying rates of body mass gain are often prescribed to optimize training adaptations, including improvements in muscular performance; however, the relationship between rate of body mass gain and muscular performance improvements, if any, is not entirely clear. …
