Effects of Acute Consumption of a Sport Drink on Athletic Performance in Student Athletes

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. Ten healthy and trained young male athletes students were selected by systematic randomly sampling and after consuming Sport Drinks (experimental group) or placebo (control group) exercised on a treadmill at the intensity of 81/8% heart rate max) %70 VO2 max (until exhaustion. Subjects received 6 ml. kg-1 body weight of Sport Drink or placebo، 40 minutes before starting of exercise bout، and they received 2 ml. kg-1 body weight of Sport Drink or placebo every 15 minutes during each exercise. To evaluate the results، independent T-test was used. Results showed no significant difference between Sport Drink and placebo trials in the total work time to exhaustion، heart rate or RPE (p>0. 05). However plasma glucose concentrations were significantly higher in sport drink group compared with the placebo group (p<0. 05). It can be concluded that the ingredient in the this sport drink did not provide any advantages to running endurance performance.
