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 …

Water Immersion Skin Wrinkling: The Influence Of Age, Sex, And Adiposity, Jonathon Kava, Daroonwan Suksom, Hirofumi Tanaka

International Journal of Exercise Science: Conference Proceedings

From the evolutionary perspective, water immersion skin wrinkling (WISW) is the perceived water drainage to enhance grip in wet conditions. In the modern medicine, it is a noninvasive test of limb sympathetic function and can be used to assess peripheral neuropathy. WISW occurs as sympathetically-mediated contraction of subcutaneous glomus bodies after perturbation of ion concentration in palmar sweat glands. This phenomenon has not been studied well. Currently, it is not clear if common demographic variations (e.g., age, sex, and adiposity) that impact overall cardio-autonomic health status also affect WISW. Purpose: The purpose of the present study is to determine if …
