Abstract:This study has been carried out in order to examine the effect of isotonic drink taken as single dose acute by athletes on endurance performance and recovery level. 2 measurements have been applied to the same athletes in this study. 12 athletes aged 18-21 who are continued both measurement programs have been integrated into the study following the evaluation. The study has been planned double blind. The test was started at 0% incline on the treadmill at a running speed of 8 km / h and after three minutes the speed was increased to 10 km / h. After the speed of 10 km/h, the running has continued by increasing the speed 1 km/h in every 3 minutes until the experimental subject stopped running. Before athletes begin to measure and 1 minute before each speed increase and blood was taken from the earlobes. Heart rate counts and lactate values were recorded during the measurement. After the experimental subject had stopped the measurement, blood has been taken from the earlobes once in every five minutes sitting. Recovery time of the athletes has been followed until their lactate level reach the level of 2 mmol/l. The differences of the group in view of the values between measurements (placebo-isotonic) has been examined by using Wilcoxon Mark test. At the end of the study, when the differences between measurements have been examined, there has been a significant difference statistically in isotonic measurements in comparison with placebo measurements in the values of heart rate, lactate and borg scale corresponding to running speed, in lactate levels corresponding to 25 min. recovery time, heart rate corresponding to 40 min recovery time and running speed values corresponding to anaerobic threshold and exhaustion level (p<0,05). As a conclusion, it has been found out that isotonic drink taken as single dose acute retards the blood and lactate levels, it has effect on recovery and exhaustion time. It has been pointed out that endurance performance is higher than the placebo measurement. It can be said that these kinds of isotonic drinks may be useful for the sports requiring long standing endurance performance.
