Effects Of Energy Drink On Metabolic Response And Exercise Performance Post Basketball Game Simulation, Kristin Russell, Frank B. Wyatt, Deok Su Yoo, Soon-Mi Choi Dr.
International Journal of Exercise Science: Conference Proceedings
Intermittent sports are characterized by intermittent bursts of high-intensity exercise and are dependent upon a combination of anaerobic and aerobic energy systems, both of which rely on carbohydrate as an important fuel source. A potential reason for athletes to use energy drinks is due to the conception that energy drinks would promote improvement of performance and this practice has been common among athletes in recent history. PURPOSE: This study examined the effects of an energy drink on metabolic parameters and exercise performance following basketball game simulation (BGS). METHODS: Six female college basketball players, aged 21.5±1.9 yrs, volunteered for this study …

International Journal of Exercise Science: Conference Proceedings
The defining feature of cancer cachexia is extensive weight loss and skeletal muscle atrophy. It is clinically important because cachexia reduces patient survival, results in functional impairment, and is estimated to be directly responsible for 20-40% of cancer deaths. Unfortunately, no clinical therapy exists and therefore, it is important to understand the molecular mechanisms responsible for rapid muscle wasting. Compared to limb muscles, the diaphragm is relatively understudied in cancer cachexia, but is likely to be adversely affected because cachexia is a systemic disease. Wasting of the primary inspiratory muscle may result in difficulty breathing and inability to adjust minute …

Effects Of Hypohydration On Muscular Performance In Females: An Ongoing Study, Joshua J. Gann, Thomas L. Andre, Paul S. Hwang, Brooke L. Roemer, Darryn S. Willoughby
International Journal of Exercise Science: Conference Proceedings
Dehydration (~3%) has been shown to negatively affect anaerobic performance. A majority of this research has been conducted using male participants. Like males, females have been shown to underestimate sweat loss, which could lead to insufficient rehydration and thus hypohydration. Additionally, due to differences in thermoregulation, it is possible that females respond to hypohydration differently than males. To date, no research has examined the effects of previous night dehydration on muscular performance in females. PURPOSE: The purpose of this ongoing study was to determine the effects of previous night dehydration on muscular strength, muscular endurance, lower body power, and …

Effects Of Dose Timing On Fluid Excretion During Sodium-Aided Hyperhydration Protocols, Shelby L. Greene, Elizaveta Roslanova, David Morris
International Journal of Exercise Science: Conference Proceedings
Co-consumption of sodium and water has been shown to be superior in promoting hyperhydration compared to consumption of an equal amount of water alone. Most sodium-aided hyperhydration studies have provided subjects with a bolus of fluid followed by a urine collection period. However the effect of providing equal amounts of fluid in a single vs. multiple doses over time on fluid retention has not been systematically studied. PURPOSE: To compare the effects of different dosing strategies on urine excretion levels following the consumption of consistent amounts of sodium and water. METHODS: Urine excretion was measured during five separate …

International Journal of Exercise Science: Conference Proceedings
The cardiovagal baroreflex is fundamental to understanding normal autonomic neural function, but can be difficult to assess. PURPOSE: In this study, we highlight the utility of the Valsalva maneuver for the assessment of cardiovagal baroreflex sensitivity during both vagal inhibition and activation. METHODS: Thirteen supine male subjects (21 ± .7 yrs; 173 ± 2 cm; 78 ± 4 kg) were instrumented with an electrocardiogram and a finger photoplethysmograph (Finometer, to assess beat-by-beat arterial pressure). Subjects then exhaled against resistance to an expiratory pressure of 40 mmHg for 15 s followed by a 2-min recovery. Subjects performed three trials, and we …
Time-Course Of Diuresis During Sodium-Aided Hyperhydration Protocols With And Without Caffeine, Elizaveta Roslanova, David M. Morris
Time-Course Of Diuresis During Sodium-Aided Hyperhydration Protocols With And Without Caffeine, Elizaveta Roslanova, David M. Morris
International Journal of Exercise Science: Conference Proceedings
When used alone, both caffeine and sodium-aided hyperhydration (SAH) are ergogenic. When caffeine is used in conjunction with SAH, diuresis occurs, but hyperhydration is still achieved albeit at lower levels when compared to SAH alone. Caffeine has been shown to be ergogenic when taken as little as 5 min, or as much as 6 hr prior to the start of exercise. Thus, determining the temporal aspects of caffeine induced diuresis when used in conjunction with SAH may lead to superior pre-exercise nutritional strategies. PURPOSE: To investigate the time-course of caffeine-induced diuresis during a 90 min SAH protocol. METHODS Subjects …

International Journal of Exercise Science: Conference Proceedings
A lifestyle compromised of predominantly sedentary behavior is a risk factor that promotes the development of metabolic syndrome. It has been demonstrated that individuals with blunted insulin sensitivity (IS) and metabolic flexibility (MF) tend to be more prone to develop the disease. An increase in physical activity is recommended in order to prevent cardiovascular disease and type 2 diabetes mellitus. PURPOSE: to determine whether healthy, sedentary, normoglycemic, Mexican American men without a family history of type 2 diabetes are able to improve IS and MF after participating in a combined (aerobic/resistance) exercise intervention. METHODS: Subjects (n=6; 21.83±0.8 years; BMI 28.92 …

Nexrutine® Mimics Exercise Preservation Of Muscle In Tramp Mice By Decreasing Proteolysis-Inducing Factor, Derek J. Wallace, Sarah Senger, Kira Pamerleau, Darpan Patel
International Journal of Exercise Science: Conference Proceedings
Cachexia is an adverse effect of prostate cancer (PCa) characterized by skeletal muscle loss which significantly impacts mortality and quality of life. Recently, proteolysis-inducing factor (PIF) mediated activation of the ubiquitin proteasome system has been identified as a potential target for treating cachexia. Oncologists encourage nutritional and physical intercession to improve outcomes, however, it is unclear how these interventions impact PIF activity. PURPOSE: To test the hypothesis that Nexrutine® (a natural bark extract of the Amur cork tree with anti-inflammatory capabilities) and exercise can independently attenuate muscle loss in a transgenic adenocarcinoma of mouse prostate (TRAMP) model by modulating …

The Relationship Of Visceral Adipose Tissue With Markers Of Energy Homeostasis Following Weight-Loss, Marcus A. Breden, Bryan K. Smith, Matthew P. Harris, Brooke Burgess, Adam Gloeckner, Melody D. Phillips, Joshua S. Wooten
International Journal of Exercise Science: Conference Proceedings
Excess levels of adipose tissue, in particular visceral adipose tissue (VAT), is closely associated with the metabolic syndrome and dysregulation of energy homeostasis. It is hypothesized that leptin resistance results in overconsumption of calories and reduced satiety. Recently, brain derived neurotrophic factor (BDNF), beyond functioning in learning and memory, is shown to play a role in energy homeostasis via its positive satiety effects on the hypothalamus. However, it remains to be elucidated how changes in visceral adipose tissue are associated with changes in circulating leptin and BDNF after weight-loss. PURPOSE: To identify changes in adiposity and circulating leptin and …

The Influence Of A Single Bout Of High-Intensity Interval Exercise On Postprandial Lipemia And Glycemia, Stephen Decker
The Influence Of A Single Bout Of High-Intensity Interval Exercise On Postprandial Lipemia And Glycemia, Stephen Decker
International Journal of Exercise Science: Conference Proceedings
A single bout of moderate-intensity aerobic exercise performed for a prolonged period of time (≥ 1 hour) has been reported to reduce the magnitude of postprandial lipemia and glycemia in both healthy and at-risk populations. High-intensity interval exercise (HIIE) bouts are generally performed in brief intervals (≤ 1 minute) followed with brief periods of rest (1 - 3 minutes) for up to 30 minutes in duration. The influence that a single bout of HIIE would have on postprandial lipemia and glycemia is not clear. PURPOSE: Examine the effects of high-intensity interval exercise (HIIE) on postprandial (PP) triglyceride (TG), glucose, and …

Fish-Oils Increase Bambi Expression To Protect Against Fibrotic Activity In Lps Stimulated Hepatic Tissue, Megan L. Schaller, Matthew P. Harris, Dakota R. Kamm, Kenneth A. Witt, Karin E. Sandoval, Joshua S. Wooten
International Journal of Exercise Science: Conference Proceedings
Non-alcoholic steatohepatitis (NASH), defined as excess hepatic lipid and chronic inflammation, provides an environment prone for the development of hepatic fibrosis. Recent evidence suggests that the antifibrotic protein BAMBI (BMP-Activin membrane bound inhibitor) is downregulated in the presence of inflammation, and may be central to the development of fibrosis. Diets rich in omega-3 (w-3) fatty acids are known to provide anti-inflammatory effects; however, the effects of w-3 fatty acids on hepatic fibrosis are not well-established. PURPOSE: To determine the effects of fish-oils on the hepatic fibrosis signaling cascade, following 32-weeks of high-fat feeding in a LPS-induced model of NASH. METHODS: …

The Effect Of A Western Diet On Hepatic Autophagy In Age Accelerated Samp8 Mice, Matthew P. Harris, Megan L. Schaller, David Umbaugh, Karin Sandoval, Kenneth A. Witt, Joshua S. Wooten
International Journal of Exercise Science: Conference Proceedings
Non-alcoholic steatohepatitis (NASH) is characterized as a dysregulation of hepatic lipid metabolism and a chronic inflammatory state. It is hypothesized the link between lipid dysregulation and inflammation may be due in part to defective hepatic autophagy and reduced mitochondrial capacity to oxidize fatty acids. It remains to be determined; however, the effects of a Western diet on hepatic autophagy and mitochondrial function during aging. PURPOSE: The purpose of this study was to determine the effect of a high-fat high fructose diet (HFF) on markers of hepatic autophagy and mitochondrial function in an age accelerated mouse model. METHODS: Twenty …
