The use of "Energy Drinks" ( @entity457 ) is increasing in India. Students specially use these drinks to rejuvenate after strenuous exercises or as a stimulant during exam times. The most common ingredient in EDs is @entity5834 and a popular @entity457 available and commonly used is Red Bull, containing 80 mg of @entity5834 in 250 ml bottle. The primary aim of this study was to investigate the effects of Red Bull energy drink on Auditory reaction time and @entity2472 . A homogeneous group containing twenty medical students (10 males, 10 females) participated in a crossover study in which they were randomized to supplement with Red Bull (2 mg/kg body weight of @entity5834 ) or isoenergetic isovolumetric noncaffeinated control drink (a combination of Appy Fizz, Cranberry juice and soda) separated by 7 days. @entity2472 ( @entity2472 ) was recorded as the highest of the 3 values of maximal isometric force generated from the dominant hand using hand grip dynamometer (Biopac systems). Auditory reaction time (ART) was the average of 10 values of the time interval between the click sound and response by pressing the push button using hand held switch (Biopac systems). The energy and control drinks after one hour of consumption significantly reduced the Auditory reaction time in males ( @entity457 232    59 Vs 204    34 s and Control 223    57 Vs 210    51 s; p < 0.05) as well as in females ( @entity457 227    56 Vs 214    48 s and Control 224    45 Vs 215    36 s; p < 0.05) but had no effect on @entity2472 in either sex (males @entity457 381    37 Vs 371    36 and Control 375    61 Vs 363    36 Newton, females @entity457 227    23 Vs 227    32 and Control 234    46 Vs 228    37 Newton). When compared across the gender groups, there was no significant difference between males and females in the effects of any of the drinks on the ART but there was an overall significantly lower @entity2472 in females compared to males. Both energy drink and the control drink significantly improve the reaction time but may not have any effect on muscular performance. Energy drink per se is no better than control drink, which may indicate that there is no role of @entity5834 in the beneficial effect seen after the drinks.
