OBJECTIVE:: It has been hypothesized that ribose supplementation rapidly replenishes adenosine triphosphate stores and thereby improves exercise performance. We compared the effects of ribose versus dextrose on rowing performance. DESIGN:: Double-blind randomized trial. SETTING:: Rowing team training area of large midwestern university. PARTICIPANTS:: Thirty-one women collegiate rowers. INTERVENTIONS:: We studied the effects of ribose versus dextrose supplementation (10 g each in 8 oz water) for 8 weeks before and after practice and 2000-m time trials. OUTCOME MEASUREMENTS AND RESULTS:: In the time trials, the dextrose group showed significantly more improvement at 8 weeks than the ribose group (median, 15.2 vs. 5.2 s; P = 0.031). CONCLUSIONS:: We doubt ribose impaired, and hypothesize dextrose enhanced, rowing performance. Further research is needed to define what role, if any, dextrose and ribose play as athletic supplements
Dextrose May Boost Sports Performance
