Effects Of Caffeine Dose Timing On The Time-Course Of Diuresis During Sodium-Aided Hyperhydration, Phillip D. Wickenheiser, Shelby Greene, Elizaveta Roslanova, Dave Morris

International Journal of Exercise Science: Conference Proceedings

When used alone, both caffeine and sodium-aided hyperhydration (SAH) can be ergogenic. Caffeine, when used with SAH, promotes diuresis, but hyperhydration can be achieved, albeit at lower levels than with SAH alone. In previous caffeine and SAH work, caffeine induced diuresis occurred only within 15 min of consumption of a bolus of caffeine, NaCl, and H₂O. This suggests that caffeine-induced diuresis may occur for only 15 min after its consumption, and/or that the diuretic effect of caffeine is dependent on hydration levels. Caffeine has been shown to be ergogenic when taken as little as 5 min before exercise; …

Effects Of Caffeine Dose Timing On Total Urine Excretion During Sodium-Aided Hyperhydration Protocols, Shelby L. Greene, David M. Morris

International Journal of Exercise Science: Conference Proceedings

When used alone, both caffeine and sodium-aided hyperhydration (SAH) can be ergogenic. Although caffeine use in conjunction with SAH promotes diuresis, hyperhydration can be achieved, albeit at lower levels compared to SAH alone. Previous caffeine and SAH work has suggested most of the caffeine induced diuresis occurs within 15 min of consumption of a bolus of caffeine, sodium and water. This response suggests that caffeine-induces diuresis for only 15 min following its consumption, and/or that the diuretic effects of caffeine are dependent on hydration levels. PURPOSE: To determine the effects of caffeine, consumed at different time-points, on diuresis during SAH …

Validity Of Four-Compartment Model Body Fat Using Single- Or Multi-Frequency Bioelectrical Impedance Analysis To Estimate Body Water, M. Lane Moore, Marqui L. Benavides, Jacob R. Dellinger, Brian T. Adamson, Claire P. Underwood, Tyler C. Dierolf, Grant M. Tinsley

International Journal of Exercise Science: Conference Proceedings

Most common body composition assessment techniques make assumptions about the body, including the density and hydration of fat-free mass (FFM). An advantage of the four-compartment (4C) model is the ability to take these FFM characteristics into account when assessing body composition, thus reducing potential error. The total body water (TBW) estimate utilized in 4C models is particularly important due to the large contribution of water to an adult human’s total body mass (~40 - 70%) and FFM (~68 - 81%); however, the impact of utilizing different estimates of TBW within 4C model has not been fully explored. PURPOSE: The …

Forsse, James K. Taylor, Zach Papadakis, Nick Schwedock, Burritt Hess, Jackson O. Griggs Md, Crawford Allison, Ron Wilson Md, Kathleen Adair, Mitch Cholewinski, Peter Grandjean

International Journal of Exercise Science: Conference Proceedings

Inflammation and oxidative stress can be potent modulators of vascular function. These factors may transiently respond to moderate-intensity steady state exercise (SSE) in a manner that improves post-exercise vascular function in healthy adults. Whether exercise imparts similar effects in adults with Stage 3 or 4 chronic kidney disease (CKD) remains understudied. Moreover, a comparison of SSE and high-intensity interval exercise (HIIE) may add to clinically-relevant findings for improving vascular function in mid-spectrum CKD. PURPOSE: To determine the influence of SSE and a comparable amount of HIIE on post-exercise inflammation and oxidative stress in patients diagnosed with secondary Stage 3 or …

Can Acute Galactic Cosmic Radiation-Induced Bone Loss Be Mitigated By Dietary Modulation Of Inflammatory Cytokines?, Sarah E. Little, Heather Cm Allaway, Rihana Bokhari, Kimberly L. Wahl, Derek V. Seidel, Nancy D. Turner, John R. Ford, Larry Suva, Susan Bloomfield

International Journal of Exercise Science: Conference Proceedings

The space environment includes weightlessness and galactic cosmic radiation (GCR), both of which can have a negative impact on bone parameters. In particular, acute exposures to space-relevant doses (2 Gy or less) of simulated GCR lead to a rapid acceleration of bone resorption activity and suppression of bone forming osteoblasts, resulting in diminished bone mineral density (BMD), strength and altered microarchitecture. A key mechanism driving these changes may be a radiation-induced increase in pro-inflammatory cytokines, such as TNF-α. Consuming a diet rich in omega-3 fatty acids has been associated with attenuated reductions in bone parameters in astronauts, mice and elderly …
