Impact Of Astaxanthin Supplementation On Postprandial Oxidative Stress, Liliana I. Renteria, Matthew J. Mcallister Feb 2020

Impact Of Astaxanthin Supplementation On Postprandial Oxidative Stress, Liliana I. Renteria, Matthew J. Mcallister

International Journal of Exercise Science: Conference Proceedings

Astaxanthin is a naturally occurring carotenoid found in salmon and microalgae that has antioxidative properties. Previous research shows dietary supplementation may result in increased endogenous antioxidant status and reduced markers of oxidative stress (OS). Research suggests OS causes increased risk for cardiometabolic and other chronic diseases, making it important to find interventions that can decrease occurrence of OS. While astaxanthin has been shown to be antioxidative, most studies observing the impact of astaxanthin has on OS has involved rodent models, therefore human trials are needed. PURPOSE: The purpose of this study was to assess whether four weeks of astaxanthin supplementation …

Impact Of Fluid Consumption On Estimates Of Intracellular, Extracellular, And Total Body Water From Multi-Frequency Bioelectrical Impedance Analysis, Marqui Benavides, Baylor A. Johnson, Patrick S. Harty, Matthew T. Stratton, Jacob Dellinger, Robert W. Smith, Abegale D. Williams, Christian Rodriguez, Sarah White, Grant M. Tinsley

International Journal of Exercise Science: Conference Proceedings

Multi-frequency bioelectrical impedance analysis (MFBIA) is able to distinguish between total body water (TBW), extracellular water (ECW) and intracellular water (ICW). Low-frequency currents are thought to primarily pass through ECW, while high-frequency currents pass through all body fluids (i.e., TBW). ICW can then be estimated by subtracting ECW from TBW. As such, MFBIA may have utility for monitoring health conditions resulting in water retention within specific fluid compartments. However, the sensitivity of fluid estimates from MFBIA is not fully established. PURPOSE: To evaluate the effects of acute fluid ingestion on body water estimates produced by a MFBIA analyzer. METHODS …

Is Age An Independent Factor In Assessing Renal Health And Function In Healthy Individuals? A Pilot Study, Eleasar Valadez, David J. Buckley, Ahmed Ismaeel, Autumn Oliver, Kathleen Adair, Evlampia Papoutsi, Kaitlyn Prezioso, Andreas Stamatis, Panagiotis Koutakis, Jeffrey S. Forsse

International Journal of Exercise Science: Conference Proceedings

Estimated glomerular filtration rate (eGFR) is a measure of renal filtration and clearance of serum creatinine and is conventionally used to characterize the progressive decline in renal function. Assessment of renal function and health is traditionally believed to be age-dependent. However, in the absence of cardiometabolic diseases (hypertension, diabetes, hyperlipemia, etc.), this may not be the case. Recently, novel markers of renal health and function support the notion that age is a secondary factor influencing renal decline. PURPOSE: To determine the magnitude of age as an influencing factor involved in the decline of renal function with novel markers of renal …
