A total of 18 male Taekwondo athletes (9 athletes for non-intake group and 9 athletes for intake group) had 90-minutes training 6 times a week for 8 weeks. To analyze the difference between the 2 groups before and after the intake, two-way ANOVA with repeated measure was performed. When looking at the change of cortisol, the main effect of time (p<.001) and interaction between time and group (p<.05) were shown. A statistical significant difference was shown before and after the intake in the groups with and without energy drink intake (p<.05). In terms of the change of serotonin, no statistically significant difference was found, but the serotonin was increased after intake of energy drink in the group with energy drink intake. The intake of energy drink 60 minutes before exercise is thought to help decrease stresses generated in training as it improves secretion of serotonin and cortisol of elite athletes who have high intensity training. However, caffeine increase vital level to offset the decreased effect of cortisol generated by exercise effect.
