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 …

Effects Of Pre-Workout Supplements On Strength, Endurance, And Mood, Anya C. Ellerbroek, Jose Antonio

Internet Journal of Allied Health Sciences and Practice

Purpose: The purpose of this pilot study was to assess the acute effects of consuming pre-workout supplements on indices of muscular strength, endurance and mood states.

Methods: In a double- blind, placebo-controlled, randomized crossover design, fourteen moderate to highly-trained recreational athletes (7 female, 7 male) participated in this investigation. Subjects came to the lab twice between testing sessions. They consumed either pre supplement (mixed with 8 to 12 ounces of water) or placebo 30-minutes prior to testing. The pre-workout supplement combination (Athelite Nutrition Inc.) contained 15.62 grams per serving, 25 kcals, that consisted of a proprietary blend including caffeine (as …
