Abestract Background & Aim: Athletes believe that energy drinks can be used to enhance their performance during training and competition. Therefore, the purpose of this study was to determine the effectiveness of acute ingestion of a sport drink on endurance performance in student athletes. Methods: ten healthy and trained male young athletes students selected systematic randomly and after consuming Sport Drink(experimental group) or placebo(control group) exercised on a treadmill at intensity of 81/8% heart rate max) %70VO2max(, until exhaustion. subjects received 6ml.kg-1body weight of Sport Drink or placebo,40 minutes before starting of exercise bout, and they received 2ml.kg-1 body weight of Sport Drink or placebo every 15 minutes During each exercise . to evaluate the results, independent T-test were used. Results: results showed no significant difference between Sport Drink and placebo trials in the total work time to exhaustion, heart rate, and RPE (p>0/05). but plasma glucose concentrations was significantly higher in sport drink group compared placebo group (p<0/05).
