Summary

The purpose of this study is to investigate whether caffeine, L-theanine (a natural amino acid found in tea), and diaphragmatic breathing exercises can help improve the game performance of esports players. Esports players often need fast reaction times, high accuracy, and mental focus during competitive gaming. This study will look at how caffeine and L-theanine supplements, either separately or together, and breathing exercises impact key performance factors like reaction time and accuracy during gameplay. The goal is to determine if these strategies can help esports players perform better by reducing stress, improving concentration, and speeding up reaction times. The findings could help inform safe, effective methods to enhance cognitive and physical performance in gaming.

Detailed description

This study explores the effects of caffeine, L-theanine supplementation, and diaphragmatic breathing exercises on esports players\' game performance, focusing on reaction time and accuracy. Caffeine is widely recognized for its stimulating effects, improving attention and reducing fatigue, while L-theanine, found in tea, is known to reduce stress and balance the effects of caffeine. Diaphragmatic breathing exercises are designed to lower stress levels, improve focus, and enhance cognitive function. The study utilizes a randomized, single-blind crossover design, where participants-esports players aged 18-30-will undergo three different interventions: caffeine only, caffeine combined with L-theanine, and caffeine combined with diaphragmatic breathing exercises. Performance outcomes, including reaction time and accuracy, will be assessed using game-based software and tests. Participants will have their performance measured before and after each intervention, allowing for comparison between the different strategies. This study aims to determine whether these supplements and exercises, alone or in combination, can serve as effective ergogenic aids, helping esports players optimize their performance by improving cognitive and motor skills, while also reducing stress. These findings could have broader applications for enhancing mental performance in competitive environments.
