Carbohydrate Effects On Cycling Time To Exhaustion Following Exercise-Induced Glycogen Depletion: Preliminary Data, Ross Moody, Nicole Cipriano, Macilynn E. Coles, Jason Stephens, Sarah Deemer

International Journal of Exercise Science: Conference Proceedings

PURPOSE: In recent years, there has been a rise in the popularity of zero sugar sports drinks which contain fewer calories (from reduced carbohydrate (CHO) content), while maintaining identical electrolyte content. However, substantial evidence demonstrates that CHO consumption before or during exercise enhances performance and supports recovery. Because zero-sugar sports drinks contain only a fraction of the carbohydrate found in traditional full-sugar formulations, they may be less effective for supporting recovery and subsequent performance following muscle-fatiguing exercise. This study investigates whether consuming a full sugar (CHO+), a zero-sugar (CHO-), or water drink following lower-body muscle fatiguing exercise improves cycling …
