Today, due to the massive propaganda that energy drink manufacturers have made in order to increase athletes' performance, this type of beverage has expanded among athletes at various levels. The purpose of this study was to evaluate the effect of energy drinks on blood glucose, fatigue index, heart rate and liver enzymes (AST, ALP) during a basketball match.
11 male basketball players (average age 22.44 ± 2.40 years, mean height 180.22 ± 4.05 cm, weight 70.22 ± 4.17 kg) were selected during two sessions (one session of energy drinking And another session of the placebo) at the time of 10 minutes before the competition (6 ml / kg body weight), and then at 10, 20, 30 and 40 minutes after the start of the competition (2 ml / kg body weight), Consumed energy drinks. 5 cc of blood were collected before consuming energy drinks and immediately after the completion of the competition to assess blood glucose levels, the index Fatigue, heart rate, and liver enzymes (AST, ALP) were collected and analyzed statistically. For data analysis, a Kolmogorov-Smirnov test was used to determine the normality of the data and the measured varibles were compared in the pre and post stages by independent t-test A significant level of (p <0.05) was considered.
The findings of this study showed a significant decrease in fatigue index, AST and ALP levels in the energy drink recipient group before and after the competition. However, the information obtained from heart rate and blood glucose levels in subjects was not significant in spite of relative changes. * Significant level of p <0.05.
The results of this study showed that ergogenic compounds in energy drinks, by delaying the accumulation of ALP and AST in the blood, increased the time to reach fatigue and improve athlete's performance, but there was no significant effect on blood glucose and heart rate in subjects. It is recommended to use energy drinks prior to the start of the competition or in the final stages of the activity to improve the performance of athletes.
