Abstract

The purpose of this study was to examine the effect of D-ribose supplementation on the changes of blood fatigue substances (lactate, ammonia, phosphate and hypoxanthine) after maximal exercise performance in college male students. The experimental trials of each subject were divided into the following conditions: placebo supplement trial and D-ribose supplement trial. The subjects exercised using a Concept Ⅱ Indoor rowing ergometer for 2,000 m Single Skull event. The subjects ingested 200 ㎎/㎏ of D-ribose after breakfast, lunch, dinner, as well as thirty minutes before exercising, for six days. Blood fatigue substances were continuously measured before exercise, immediately after exercise, and thirty minutes after exercise. The results indicated a significant difference in blood phosphate and hypoxanthine levels between the two experimental trials in the 30 minute recovery period (p<0.05). However, there were no significant differences in blood lactate and phosphate levels between the two experimental trials. The results of our study suggest that D-ribose supplementation during maximal rowing exercise for 7~8 minutes may contribute to the improvement of metabolic responses as a beneficial ergogenic aid accelerating fatigue clearance.
