Aim: The aim of this study was to investigate the effects of short-term caffeine supplementation on athletes' electroencephalographic signals during a strenuous exercise session. Methods: This quasi-experimental study consisted of a female student-athlete aged 24-28 years with at least two years of experience in sports. From this population, 20 people who voluntarily had the necessary conditions to enter this study were selected as a sample and were randomly divided into two groups of 10: experimental group (athlete consuming caffeine supplement) and control group (athlete taking placebo). And capsules containing caffeine (at a dose of 6 mg / kg body weight) and starch were consumed by each subject without knowing the contents of the capsule and one hour before the start of the exhausting protocol. For both groups, Bruce exhausted exercise protocol was performed to the point of fatigue, which consisted of six to seven three-minute steps with varying inclination and speed of the turntable. Also, all subjects were measured brain waves by electroencephalography in three stages (half an hour before caffeine consumption and one hour after caffeine consumption and after the exhaustion test). Results: The results of this study showed that a session of strenuous exercise along with short-term caffeine supplementation in athletes causes significant changes in delta waves in the right hemisphere forehead and beta waves in the left hemisphere forehead (P <0.05). Conclusion: Short-term caffeine supplementation before participating in an exhausting exercise activity session can improve electroencephalographic signals in athletes.
