Effects of Caffeine, L-Theanine, and Diaphragmatic Breathing on Esports Players' Performance

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.
