Effects Of A Carbohydrate Hydrogel Beverage On Endurance Cycling Performance And Gastrointestinal Comfort, Harrison R. Toney

Masters Theses, 2010-2019

PURPOSE: This study examined the effects of a novel maltodextrin-fructose hydrogel (MF-H) on cycling performance and gastrointestinal distress symptoms. METHODS: Nine endurance-trained male cyclists completed three experimental trials consisting of a 98-min varied-intensity cycling protocol followed by a performance test of ten consecutive sprint intervals. In a cross-over design, subjects consumed 250 mL of a treatment beverage every 15 min of cycling. The treatments consisted of 78 g ^. hr^-1 of either a) MF-H, b) maltodextrin-fructose (MF), and c) maltodextrin only (MD) All data were assessed using repeated measures ANOVA’s. RESULTS: There were no differences in average sprint power …

Caffeine Intake Helps Maintain 3-Km Cycling Performance The Morning Following Sleep Restriction, Erin E. Horil

Masters Theses, 2010-2019

Abstract

Introduction: Although a full understanding of the role of sleep is debated, it is widely accepted that sleep is important for recovery from heavy exercise. Recent research suggests that sleep restriction (SR) may negatively impact recovery and subsequent performance. It is unknown if caffeine supplementation mitigates this performance decrement. Our objective was to investigate the effect of caffeine supplementation on exercise performance following one night of SR in trained cyclists.

Methods: Subjects (n=10) completed a 3-km time trial (TT) and an exhaustive bout of exercise in the evening (EX1), then returned to repeat the TT the following …
