The Effect of Hype Energy Drink on Performance Indicators and Blood Lactate in Elite Badminton Players

In recent years, consumption of energy drinks has increased significantly in athletes to enhance performance during training and to succeed in competitions. The aim of this study was to investigate the effect of Hype energy drink before exercise on performance indicators and blood lactate of elite badminton players. 10 male elite badminton players from Guilan province (mean age 16.6±0.52 years, height 172.9±9.16 cm, weight 68.90±10.33 kg, body fat 11.66±6.3%) were selected purposefully. Subjects consumed 6 mg/kg energy drink and placebo (15 min. before test) using crossover counterbalanced method during two sessions with an interval of 4 days with double blind method. In these sessions, participants performed one repetition maximum and 60% of one repetition maximum in the chest press and leg press, anaerobic Rast test, 45 m sprint, Illinois agility test, Shuttle run 20 m aerobic test after a standard breakfast. Also, 5 cc of blood was collected from brachial vein before, immediately and 5 minutes after Rast test to measure blood lactate and the results were recorded. For data analysis, SPSS version 20 and Paired t test were used. Results showed that aerobic performance significantly improved in energy drink consumers (P<0.05), whereas changes in power, muscular endurance, sprint, agility and anaerobic power were not significant between energy drink and placebo consumers (P>0.05). Also, no significant changes in blood lactate levels were observed before, immediately and 5 minutes after the test between energy drink and placebo consumers (P>0.05). It seems that acute consumption of Hype energy drink has no significant effect on performance indicators and blood lactate of badminton players and it only improves their aerobic performance.
