About this study
Official title: Graduate Program in Department of Exercise Health Science, National Taiwan University of Sport
Purpose: investigators explored the effect of 3 mg/kg of caffeine supplementation on the cognitive ability and shooting performance of trained e-sports players. Methods: investigators recruited nine e-sports players who had received professional training in e-sports and had won at least eighth place in national-level e-sports shooting competitions. After performing three to five familiarization tests, investigators employed a randomized crossover design to divide participants into a caffeine trial (CAF) and a placebo trial (PL). The CAF group took capsules with 3 mg/kg of caffeine, whereas the PL group took a placebo capsule. After a 1-h rest, the Stroop task, visual search ability test, and the shooting ability test were conducted.

What is being measured
The primary outcome is the main question the study is designed to answer.
Stroop task
The color-word Stroop task and visual search test were conducted using Psych/Lab for Windows. The reaction time (millisecond) were recorded.
Measured: 1 hour after intervention
visual search test
A total of 80 search displays were presented in 5 minutes. In each display, 5, 10, 15, or 20 -Tests were presented. The reaction time (millisecond) were recorded.
Measured: 1 hour after intervention
Secondary outcomes (1)
aim trainer
Participants used the mouse to shoot the electronic targets on the computer screen. The completed time (second) were recorded.
Measured: 1 hour after intervention

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Purpose: investigators explored the effect of 3 mg/kg of caffeine supplementation on the cognitive ability and shooting performance of trained e-sports players. Methods: investigators recruited nine e-sports players who had received professional training in e-sports and had won at least eighth place in national-level e-sports shooting competitions. After performing three to five familiarization tests, investigators employed a randomized crossover design to divide participants into a caffeine trial (CAF) and a placebo trial (PL). The CAF group took capsules with 3 mg/kg of caffeine, whereas the PL group took a placebo capsule. After a 1-h rest, the Stroop task, visual search ability test, and the shooting ability test were conducted.
